Is Your AC Ready for a Missoula Summer?

May is the sweet spot in Missoula. The snow has melted, the hiking trails are opening up, and warm afternoons are right around the corner. But before those hot July days arrive, there's one thing every Missoula homeowner and business should put on the to-do list: making sure your air conditioning system is ready to perform.

At Air Quality Mechanical, we've been serving the Missoula community for more than 27 years. Every spring, we see the same pattern: people wait until the first heat wave hits, then scramble to get their AC looked at and often find a simple issue that could have been caught months earlier. This May, we want to help you get ahead of the curve.

Why May Is the Best Time for AC Maintenance

Montana summers can arrive fast. Once temperatures climb into the 90s, HVAC technicians across the valley get slammed with service calls. Scheduling your AC tune-up in May means:

You'll get your preferred appointment time with no waiting a week in the heat
Any needed parts or repairs can be handled before peak demand
Your system will run more efficiently from day one of summer, saving you on energy bills
Problems caught early are almost always cheaper to fix than emergency breakdowns

What Does an AC Tune-Up Include?

When our technicians come out for a spring AC check, we are thorough, not just quick. Here's what a typical maintenance visit covers:

Inspecting and cleaning the evaporator and condenser coils
Checking refrigerant levels and looking for any signs of leaks
Testing and calibrating the thermostat for accurate temperature control
Inspecting electrical connections, capacitors, and contactors
Lubricating moving parts to reduce wear and tear
Clearing the condensate drain to prevent moisture buildup and water damage
Checking airflow through the system and inspecting ductwork for issues

A well-maintained system doesn't just cool better and it lasts longer and costs less to operate. We service and install top brands including Daikin, Goodman, and Honeywell, so whether you have a central AC unit or a ductless mini-split, our team has the experience to keep it running right.

Signs Your System Needs More Than Just a Tune-Up

Sometimes a maintenance visit reveals that a system is past the point of a simple tune-up. Here are warning signs that your AC may need repair or replacement this spring:

Warm air blowing from your vents even when the AC is running
Unusual noises such as banging, squealing, or grinding
Frequent cycling on and off (short-cycling)
Higher-than-normal energy bills without a clear reason
Uneven cooling in different rooms or areas of your home
The unit is 10 to 15 years old or older

If any of these sound familiar, don't wait until summer to address them. Our team can diagnose the issue quickly and we will walk you through your options, whether that's a targeted repair or a conversation about upgrading to a more efficient system.

Consider a Ductless Mini-Split for Problem Rooms

If you have a garage, sunroom, addition, or room that never seems to cool down properly, a ductless mini-split system might be exactly what you need. Mini-splits provide targeted heating and cooling without requiring ductwork, making them a great solution for older Missoula homes or spaces that aren't connected to your central HVAC system.

Air Quality Mechanical installs and services ductless systems for both residential and commercial customers. These systems are energy-efficient, quiet, and give you zone-by-zone control over your comfort. Call us to find out if a mini-split is a good fit for your space.

Don't Forget Your Indoor Air Quality

Missoula residents know all too well how wildfire smoke can blanket the valley during summer months. When air quality outside drops, the air inside your home matters even more. This May, it's also a good time to think about:

Replacing your HVAC air filter (or upgrading to a higher-MERV filter)
Scheduling a duct vac cleaning to remove dust, debris, and allergens from your ductwork
Looking into the Refresh Air Purifier for cleaner indoor air during smoke season

We carry and install the Refresh Air Purifier, which is specifically designed to help remove smoke particulates and other airborne contaminants from your home's air. If last summer's smoke season left you frustrated, this is worth a conversation.

Preparing Your HVAC System for Spring

Winter in Missoula can strain your HVAC system. Long run times, freezing temps, and constant cycling take a toll on furnaces, filters, and ductwork. As we shift into spring, now is the time to reset your system before Air Conditioning season begins.

Here’s a quick checklist to get your HVAC system ready:

1. Replace Your Air Filter

After months of heating, your air filter is likely full of dust and debris. A clogged filter restricts airflow, reduces efficiency, and increases wear on your furnace or ac system. Starting spring with a fresh filter helps your system run smoothly.

2. Check Your Outdoor Unit

If you have an AC unit or heat pump, clear away leaves, branches, and debris around it. Make sure there is open space around the unit so it can breathe properly when warmer weather hits.

3. Open and Clear Vents

Walk through your home and make sure vents and returns are not blocked by furniture or rugs. Vacuum visible dust buildup and confirm everything is open to support balanced airflow.

4. Test Your AC Before You Need It

Do not wait for the first hot day in Missoula to turn on your air conditioning. Switch your thermostat to cooling mode and make sure the system runs properly, blows cool air, and does not make unusual noises.

Testing early gives you time to address small issues before peak summer demand.

5. Schedule Professional Spring Maintenance

After a long winter, a professional inspection helps catch worn parts, airflow issues, or efficiency problems before they turn into breakdowns. Routine maintenance improves performance, lowers energy costs, and extends the life of your system.

If you need HVAC maintenance in Missoula, MT, contact Air Quality Mechanical at (406) 721-7018 to schedule your spring service.

How Often Should You Service Your Furnace In Montana’s Climate?

Fri, 31 Oct 2025 18:47:45 GMT

How Often Should You Service Your Furnace In Montana’s Climate?

When the temperatures drop across Montana, your furnace becomes one of the most important systems in your home. Whether you’re in Billings, Bozeman, or up near the Hi-Line, Montana’s long, cold winters mean your furnace works overtime, and that makes regular maintenance critical.

But how often should you really be servicing your furnace to keep it running efficiently and reliably? Let’s break it down.

Why Furnace Maintenance Matters in Montana

Montana’s climate is tough on heating systems. Between heavy snow, fluctuating temperatures, and dry indoor air, your furnace is under constant stress for months at a time. Regular servicing isn’t just about comfort; it’s about prevention.

Routine maintenance helps:

Catch small issues before they become costly repairs
Improve energy efficiency (saving you money on heating bills)
Extend the life of your furnace
Ensure safe operation, especially when it comes to gas or carbon monoxide concerns

Recommended Service Frequency

For most homeowners in Montana, an annual furnace service is the sweet spot.

Here’s why once a year is ideal:

Usage intensity: Your furnace typically runs from October through April, and sometimes longer in the mountains. That’s a lot of hours.
Dust and debris buildup: Montana’s dry climate can mean more dust circulating through your system, clogging filters and reducing efficiency.
Manufacturer warranties: Many warranties require yearly professional maintenance to stay valid.

Bottom line: Schedule a furnace tune-up every fall before heating season begins.

What a Professional Furnace Service Includes

A professional technician will do more than just swap out your filter. A full service typically includes:

Checking and cleaning burners, blower, and ignition system
Inspecting the heat exchanger for cracks or corrosion
Testing carbon monoxide levels and safety controls
Verifying thermostat calibration and performance
Lubricating moving parts and tightening connections
Replacing or cleaning air filters

At Air Quality Mechanical, our technicians also make sure your furnace is running efficiently for your specific home setup so you’re not wasting fuel or energy.

Signs You Might Need an Extra Service Visit

While once-a-year maintenance is standard, some signs mean your furnace may need extra attention:

Uneven heating or weak airflow
Strange noises such as rattling, banging, or squealing
Higher-than-usual energy bills
Furnace running constantly or short cycling
Unusual smells when the system starts up

If you notice any of these, don’t wait for your next tune-up. Call a professional before it turns into a breakdown.

A Quick Tip for Homeowners

Between professional services, you can help your furnace by:

Changing filters every 1–3 months, especially during peak heating season
Keeping vents and returns clear
Checking thermostat batteries each fall
Watching for warning signs like uneven heating
Stay Warm and Worry-Free

Montana winters are no joke, but with a well-maintained furnace, you can stay cozy and confident all season long. Scheduling your annual service each fall ensures your system runs efficiently, safely, and reliably when you need it most.

At Air Quality Mechanical , we’re proud to help Montana homeowners stay comfortable through every cold snap.

Getting Your Furnace Ready For Heating Season In Montana

Fri, 31 Oct 2025 18:44:14 GMT

Getting Your Furnace Ready For Heating Season In Montana

We hope you’ve all had a wonderful summer. It might feel a little early to be thinking about heating season, but with cool Montana mornings and chilly nights already showing up, many of us are starting to think about turning the furnace on for the first time.

We want to share a few simple tips to help make that transition from cooling season into heating season go smoothly for you and your home.

1. Start Fresh with a Clean Air Filter

Here’s something a lot of people don’t realize: your air conditioning and your furnace use the same blower, the same ductwork, and the same filter. So that filter you’ve been running all summer for cooling (and probably through a lot of smoky air) is the same one your furnace will use.

If your filter has been in there 2–3 months, it’s ready for a replacement. A fresh filter keeps your furnace running efficiently, prevents overheating, and helps your indoor air stay cleaner. If you’re not sure where your filter is or what size you need, don’t worry. Give us a call at Air Quality Mechanical—we’ll make sure you get the right filter for your system.

2. Change Those Thermostat Batteries

Here’s a little thing that gets overlooked: thermostat batteries. When’s the last time you changed them? For most people, it’s been a while. We recommend doing it once a year, right at the start of heating season.

Why? Because dead batteries can shut down your furnace. Imagine being away on vacation and your thermostat dies—the furnace stops, the house gets cold, and you could be dealing with frozen pipes. Replacing those batteries now is a quick and easy way to avoid headaches later.

3. Check Your Furnace Vent Pipes

If you’ve got a high-efficiency furnace, you probably have two PVC vent pipes running out the side of your house. These are really important: one brings in fresh air for combustion, the other exhausts gases like carbon monoxide.

Over the summer, critters love to make those pipes their home—bees, birds, even mice. Add in leaves or maybe a kayak or bike leaned up against the wall, and suddenly your furnace can’t breathe. Before you fire it up this fall, make sure those pipes are clear and free of debris.

4. Schedule a Furnace Tune-Up

Lastly, one of the best things you can do for peace of mind is have a professional tune-up before the real cold hits. Just like going to the doctor or dentist, your furnace needs a check-up too. Preventive maintenance helps catch small issues before they turn into big problems, keeps your system running safely, and extends the life of your equipment.

At Air Quality Mechanical, we take pride in treating our customers like family. A seasonal tune-up gives you confidence that when the temperatures drop, your furnace will be there for you—safe, reliable, and efficient.

Final Thoughts

So there you go:

Fresh filter
Fresh thermostat batteries
Clear vent pipes
Professional tune-up

Four simple steps that can make all the difference heading into Montana’s heating season.

If you need help with any of these, don’t hesitate to reach out to us at Air Quality Mechanical. We’ll make sure your home stays warm, safe, and comfortable all winter long.

Before The Heat Hits Missoula: Here’s Our Go-To List To Prepare Your AC For Summer

Fri, 31 Oct 2025 18:41:57 GMT

Before The Heat Hits Missoula: Here’s Our Go-To List To Prepare Your AC For Summer

When summer rolls into Missoula, MT, keeping your home cool and comfortable becomes a top priority. If your air conditioner struggles to keep up or your energy bills are higher than expected, it's likely time for a little TLC. As someone who's been through many Montana summers, I want to share my personal checklist for getting your AC ready. These tips not only help your system perform better but can also save you money and avoid costly repairs.

1. Start With the Air Filter: The Simplest Way to Boost AC Performance

One of the easiest and most overlooked tasks in air conditioning maintenance is changing the air filter. A dirty filter can obstruct airflow, forcing your AC to work overtime to push air through your home. This makes cooling less effective and drives up your energy bills.

For best results, I recommend replacing your filter at the beginning of each season—or even more frequently if you have pets or live near dusty roads. Depending on your filter's MERV rating, it may clog faster and require more regular replacement. Clean filters keep your system running smoothly and your indoor air cleaner.

2. Clear Around the Outdoor Unit: Keep the Heart of Your AC Unblocked

Next up is the outdoor condensing unit—that big box sitting in your yard. This is where a lot of the magic happens, and it needs room to breathe. Cottonwood fluff, lawn clippings, and dirt can block airflow and reduce your unit's efficiency.

Every spring, I make a habit of clearing out debris around the unit. Make sure plants and objects are kept at least 2-3 feet away. A clean, unobstructed condensing unit allows your air conditioner to release heat properly, which is key during those scorching Missoula afternoons.

3. Optimize Your Thermostat: Avoid Making Your AC Work Too Hard

Your thermostat settings play a bigger role than you might think. Cranking the temperature way up when you leave for work and back down when you return forces your AC to play catch-up during the hottest part of the day.

Instead, I recommend keeping your thermostat within about 4 degrees of your desired comfort level. Even better—consider using a programmable or Wi-Fi thermostat. I personally use one to schedule cooling so my house starts to chill before I get home. It takes the edge off while saving energy.

4. Improve Airflow Throughout Your Home

Proper airflow makes a huge difference in keeping your home evenly cooled. One mistake I see often is people closing doors and vents in unused rooms. While it may seem like a way to save energy, it actually disrupts circulation and strains your system.

Make sure all your registers are open and doors throughout the house are kept ajar when your AC is running. This allows air to circulate freely and helps every room reach a comfortable temperature.

5. Invest in Preventative Maintenance: Stay Ahead of Potential Problems

Even if you stay on top of your own checklist, professional maintenance is essential. At Air Quality Mechanical, we offer preventative maintenance plans that make things easy. We handle the scheduling and reach out when it’s time for a tune-up—so you don’t have to remember the last time your AC was checked.

Routine service catches small issues before they turn into big problems, helps your system last longer, and keeps it running at peak efficiency. I’ve seen firsthand how a well-maintained unit can make it through the toughest summers without breaking a sweat.

Stay Cool and Comfortable All Summer Long

Preparing your air conditioner now can save you from discomfort, expensive repairs, and sky-high energy bills later. Simple steps like changing your air filter, clearing your outdoor unit, optimizing your thermostat, and keeping airflow balanced all add up.

And when it comes to professional air conditioning repair in Missoula MT or ongoing maintenance, we’re always here to help. At Air Quality Mechanical, we treat your home like our own. Book your service today and make sure your AC is ready to keep you cool when you need it most.

Understanding SEER Ratings: What They Mean For Your HVAC System

Fri, 31 Oct 2025 18:39:10 GMT

Understanding SEER Ratings: What They Mean For Your HVAC System

When it comes to cooling your home in Missoula’s summer heat, efficiency matters — not just for your comfort, but also for your wallet. If you’ve ever wondered what are SEER ratings, what is a good SEER rating, or what do SEER ratings mean when your HVAC technician mentions them, you’re in the right place.

At Air Quality Mechanical, we’ve been in the business long enough to know that energy bills can sneak up on you fast — especially if you’re running an older AC system. This article breaks down SEER ratings in a way that makes sense and helps you figure out if an upgrade might be the right move.

What Are SEER Ratings?

Let’s keep it simple. SEER stands for Seasonal Energy Efficiency Ratio. It’s a way to measure how efficient your air conditioner is throughout the cooling season.

The higher the SEER rating, the more efficiently your unit cools your home — and the less it costs you to run it.

Think of it like fuel economy for your car. A car that gets 30 miles per gallon is going to cost a lot less to drive than one that gets 15. Same goes for your AC — higher SEER = lower energy use.

What Is a Good SEER Rating?

The industry standard has shifted over the years. A decade or two ago, a 10 SEER unit was normal. Today, the minimum rating is 13 SEER, but newer systems can go up to 20 SEER or more.

Here’s what that means in real-world terms:

Upgrading from a 10 SEER to a 16 SEER system? That’s about 37% savings on your cooling costs.
Jumping from a 10 to a 20 SEER? You’re looking at 50% savings.

So if you’re spending $200/month cooling your home in July, that could drop to $100 with a more efficient system. Over the years, those savings really add up — your system essentially pays for itself.

More Than Just Efficiency: Comfort & Noise

It’s not all about the energy bill. Higher-SEER systems come with comfort perks, too.

Many of them use inverter technology — something we’ll cover in more detail another day — but for now, just know this: it helps your system run more smoothly, more quietly, and at more consistent temperatures. No more rollercoaster temps. Just steady, cool comfort throughout your home.

Also? These newer systems are way quieter. If you’ve ever had your lights dim when the AC kicks on, or if your current unit sounds like a jet engine firing up, you know what I mean.

The new systems don’t do that. They draw less power, kick on gently, and run quieter. You might not even notice they’re on — which is kind of the point, right?

When to Consider Upgrading

Here’s a quick checklist to see if you should think about replacing your old AC:

Your current system is 10+ years old
Your energy bills keep climbing
The system struggles to keep up on hot days
Your home has uneven cooling or hot spots
It’s loud or causes your lights to flicker when it starts

If any of that sounds familiar, it might be time to talk to someone about a replacement. And hey — that doesn’t mean you need to go for the fanciest system out there. It just means finding the right SEER rating for your comfort, your climate, and your budget.

Final Thoughts: SEER Ratings Matter

Upgrading your AC system is a big decision, but when you understand what SEER ratings actually mean, it becomes a little easier to see the value. You’ll save money month-to-month, get better comfort all summer long, and enjoy a quieter, more reliable system.

We’re always here to help if you’re thinking about making the switch. At Air Quality Mechanical, we treat your home like it’s our own. No pushy sales talk — just honest advice from folks who’ve been in the HVAC game for decades.

So if you're ready to stay cool and stay efficient, give us a call. We'll help you find the right system with the right SEER rating — and make sure you're taken care of from day one.

The Key to Energy Savings: Regular HVAC Maintenance And Smart Thermostat Use

Fri, 31 Oct 2025 18:35:21 GMT

The Key to Energy Savings: Regular HVAC Maintenance And Smart Thermostat Use

Why Regular HVAC Maintenance Matters

Keeping your HVAC system in top shape isn’t just about avoiding breakdowns—it’s also one of the smartest ways to save energy and lower your utility bills. A well-maintained system runs more efficiently, which means less wasted energy and more money in your pocket. In Montana’s extreme weather conditions, regular maintenance becomes even more essential to keep your home comfortable year-round.

How Smart Thermostats Help You Save

One of the most effective ways to maximize energy efficiency is by using a smart thermostat. These devices allow you to fine-tune your home's temperature settings for optimal savings. Instead of making drastic adjustments, which can cause your furnace to overwork, a smart thermostat enables gradual changes that help maintain efficiency and comfort.

For Montana homeowners, a 3 to 5-degree setback at night can lead to noticeable energy savings. Drastic setbacks of 7 to 10 degrees may seem beneficial, but in colder climates, they can actually increase energy consumption when your furnace has to work harder in the morning to reheat your home. A smart thermostat can automate these adjustments for you, ensuring optimal energy use while keeping your home comfortable.

Protecting Your Home from Extreme Cold

When temperatures drop to zero or below, it’s crucial to keep your furnace running consistently. Turning it down too low can put your home at risk. Here’s why:

Your pipes, crawl spaces, and exterior walls absorb the cold, increasing the risk of frozen or burst pipes.
High-efficiency furnaces need to run consistently to prevent intake and exhaust pipes from freezing, which can cause the entire system to shut down.
If you leave for vacation and set your thermostat too low, your furnace may not cycle often enough to keep critical components warm, leading to failures and potential home damage.

A Wi-Fi-enabled smart thermostat can help you avoid these issues by allowing you to monitor and adjust your home’s temperature remotely. If temperatures drop unexpectedly, you can make quick adjustments to protect your home.

Additional Benefits of Smart Thermostats

Beyond energy savings and home protection, smart thermostats offer several other benefits:

Remote Monitoring: Check and control your home’s temperature from anywhere.
Energy Usage Reports: Track your heating and cooling patterns to optimize efficiency.
Vacation Mode: Prevents unnecessary energy use while ensuring your home stays safe.
Automatic Adjustments: Learns your schedule and preferences for optimal heating and cooling.

The Bottom Line: Combine Maintenance with Smart Tech for Maximum Savings

Preventative HVAC maintenance ensures your system runs efficiently, prevents costly breakdowns, and helps you manage your energy usage effectively. When paired with a smart thermostat, you gain even more control over your home’s energy consumption, leading to lower utility bills and a more comfortable living space.

Don’t wait until the first cold snap to think about your HVAC system—schedule regular maintenance today and consider upgrading to a smart thermostat for even greater savings and peace of mind.

How Old Is Too Old For Your HVAC System?

Fri, 31 Oct 2025 18:30:17 GMT

How Old Is Too Old For Your HVAC System?

If you’re wondering whether your HVAC system is reaching the end of its lifespan, you're not alone. Many homeowners are unsure of when to replace their heating and cooling systems. The truth is, HVAC systems have a limited lifespan, and if yours is pushing the 15-20 year mark, it's time to start thinking about maintenance or replacement.

In this article, we’ll explore the key signs that your HVAC system might be getting too old, why age matters, and how regular HVAC maintenance can keep your system running smoothly—or help you decide when it’s time for a replacement.

The Lifespan of Your HVAC System

Most HVAC systems are designed to last between 15 and 20 years, depending on the manufacturer, usage, and maintenance. However, as your system ages, it becomes more prone to wear and tear. The older your system gets, the harder it is to ensure reliability, safety, and efficiency.

Why Age Matters

As your HVAC system ages, it’s more likely to experience problems like:

Reliability Issues: Older systems are less dependable. If you leave the house, you might worry about whether your furnace will continue to work properly, especially if you're relying on it to keep your home warm while you're away. After the 15-year mark, breakdowns become more common, leading to higher repair costs and unexpected inconveniences.
Safety Concerns: One of the biggest risks of an aging HVAC system is the potential for dangerous issues like carbon monoxide leaks. Stress cracks can form in your heat exchanger, which can result in carbon monoxide poisoning. This is a serious safety concern and a leading reason why you don’t want to ignore your HVAC system when it’s getting old.
Cost of Repairs: After a certain point, the cost of repairs often outweighs the cost of replacement. If your system is nearing 20 years old and is breaking down frequently, it might be time to start looking at newer, more efficient options.

Signs Your HVAC System Needs Replacing

While regular maintenance can prolong the life of your HVAC system, there are some signs that indicate it’s nearing the end of its useful life. Here are a few red flags to watch for:

Frequent Breakdowns: If your furnace or air conditioner is breaking down often, it's a clear sign that it's reaching the end of its life. Repeated repairs can add up quickly, and before long, it could cost more to keep fixing your system than to replace it with a new, more efficient model.
Uneven Heating or Cooling: Do you notice that certain rooms are too hot or too cold, no matter how you adjust the thermostat? This could be a sign of an inefficient HVAC system. An old HVAC system struggles to distribute air evenly, and this could mean that it’s no longer working as effectively as it once did.
Rising Energy Bills: Older HVAC systems aren’t as efficient as modern units. If your energy bills are climbing despite no major changes in your home’s usage, it could be a sign that your system is working overtime to keep your home comfortable. Replacing your old unit with a new, energy-efficient system could lead to significant savings.
Strange Noises: Unusual noises like rattling, buzzing, or banging sounds are never a good sign. These could indicate that your system’s components are wearing out and need immediate attention. If your HVAC is making noise, it could be time to start thinking about replacement.

The Importance of Preventive Maintenance

If your HVAC system is under 20 years old and you want to make sure it runs as smoothly as possible, regular maintenance is key. Just like changing the oil in your car, scheduling annual HVAC service is a smart investment that can keep your system running efficiently for years to come.

How Preventive Maintenance Helps

Safety Checks: During a maintenance visit, technicians check critical components, like the heat exchanger, for stress cracks that could cause carbon monoxide leaks. This is a crucial safety measure, especially for older systems.
Extended Lifespan: Regular cleaning and inspection help prevent premature wear on your system, potentially adding years to its life. In fact, a well-maintained system can often last longer than one that’s neglected.
Maximized Efficiency: Regular tune-ups ensure that your system is running as efficiently as possible, which can save you money on energy bills and prevent breakdowns when you need your system most.

When to Schedule HVAC Maintenance

To avoid emergency repairs, it’s wise to schedule HVAC maintenance at least once a year. Ideally, you should have your system serviced before the heating season in fall and the cooling season in spring. This ensures your system is in top shape when you need it the most.

Replacing Your HVAC System

If your system is showing signs of major problems, or if it’s pushing the 20-year mark, you might be looking at a full replacement. Here’s what you need to know about the replacement process:

The Installation Process: Replacing an HVAC system is not a simple task. Depending on your home, the size of the system, and any additional installation requirements, it could take a full day or more to complete the job. While this might sound like an inconvenience, remember that a new system will save you money in the long run by being more efficient and reliable.
Finding the Right HVAC Contractor: When it's time to replace your system, you want to work with a trusted, experienced professional who can ensure that your new unit is properly installed. Look for a company with a good reputation—online reviews, referrals from friends and family, and years of experience are all signs of a company you can trust.

At Air Quality Mechanical, we've been proudly serving our local community for over 30 years. As a family-owned business, we treat our customers like family, ensuring that you receive the highest level of service and peace of mind.

Conclusion: Don't Wait Until It's Too Late

If your HVAC system is more than 15 years old, it’s time to start considering maintenance or replacement. Regular HVAC maintenance can help you avoid dangerous breakdowns and costly repairs, while also improving the efficiency and safety of your system.

If you're unsure whether it’s time to replace your old furnace or air conditioner, call us at Air Quality Mechanical for a thorough inspection and peace of mind. We're here to help ensure your home stays safe and comfortable year-round.

Why Your Thermostat Settings Matter More In Montana Winters

Fri, 31 Oct 2025 18:25:15 GMT

Why Your Thermostat Settings Matter More In Montana Winters

Stay Warm, Save Money: The Importance of Proper Thermostat Settings

Living in Montana means braving some seriously cold winters. When temperatures drop, your HVAC system works overtime to keep your home warm. But did you know that the way you set your thermostat can impact your energy bills, home comfort, and even your indoor air quality? Let’s dive into why thermostat settings matter and how proper HVAC maintenance—including duct cleaning—can help you save money and breathe cleaner air.

The Thermostat Myth: Turning It Way Down Doesn’t Save Energy

Many homeowners believe that drastically lowering their thermostat at night saves energy. In reality, setting it too low can actually cost you more.

Here’s why:

When you set your thermostat way back, not only does the air cool, but your walls, floors, and furniture do too.
In the morning, your furnace has to work harder—and use more energy—to heat everything back up.
Instead of big temperature swings, we recommend only setting your thermostat back by 3 to 4 degrees at night for better efficiency.
If you have a boiler system, leave it at a steady, comfortable temperature year-round. Boilers work best when maintaining a constant heat level.

How Proper Furnace Maintenance Saves You Money

Keeping your HVAC system well-maintained is key to energy efficiency and system longevity. A neglected furnace doesn’t just work harder—it also burns more fuel, leading to higher energy costs.

Here’s what you can do:

Check and replace your furnace filter monthly. A clogged filter makes your furnace work harder to pull in air, which wastes energy.
Vacuum around your furnace to reduce dust and debris that can get inside and impact efficiency.
Schedule an annual HVAC checkup to ensure your burners are combusting properly and your system is running at peak performance.

The Hidden Problem: Dirty Ductwork

Even if your furnace is running efficiently, dirty ducts can reduce airflow and hurt your indoor air quality. Over time, your duct system collects dust, dirt, and even construction debris—especially if you’ve never had them cleaned before.

Signs Your Ducts Need Cleaning:

Increased dust buildup in your home, even after cleaning.
Musty or stale odors coming from your vents.
Higher energy bills due to restricted airflow making your furnace work harder.

Tips To Keep Your A/C Working Properly

Tips To Keep Your A/C Working Properly

Why does my Air Conditioner freeze? Is there anything I can do to prevent it? Those are two of the most common questions we get this time of year, especially when the temps have hit the mid 90’s for a few days. There are a few things that you can do if your A/C freezes:

Turn the air conditioner off at the thermostat at night, do not run it all night long when the temperature outside is cooler then what you have the thermostat set for.
Make sure that the airflow isn’t restricted. Have you checked the filters? Are they very dirty? Change them.
If the system did have ice on it, run just the fan from the thermostat for a few hours giving the coil time to defrost. Then try running the air conditioner again. If your system freezes up again you will need to call a Service Tech to check for leaks.
Don’t set the temperature to below 72 degrees. Asking it to keep your whole house cooler then that puts undue stress on the unit.

Ways to make sure that your system has good airflow and is keeping your house cool:

Make sure that there are no vents closed or things blocking the air flow through the vents. Make sure curtains or furniture don’t block the vents. Air conditioners rely on good air flow to prevent the air from backing up and forming ice around the coil.
Make sure your home has adequate air returns. An air return can make a world of difference moving the air through your home.
Make sure the filter is changed monthly during the summer months.
Keep your system maintained. Call for your A/C tune up as early as possible in the spring so that the Technician has the time to spend going over your unit and checks everything over properly.
Don’t put anything on or around the outdoor unit as that can restrict air flow and make sure that none of the fins are bent or broken.
Keep watch over your pets so that they don’t use the outdoor unit as a watering station. Talk with your Service Technician about options to protect your outdoor unit. Custom made A/C covers are available through our office.

With a little thought and timely maintenance you can keep your A/C working properly during even the hottest parts of the summer. If you don’t have Air Conditioning reach out to us for a free quote (406) 721-7018. A/C can typically be installed in a day.

Furnace and A/C FAQs

Furnace and A/C FAQs

Ever wondered what a Heat Exchanger is? Or how it works to keep your home warm? Or why is the Air Conditioner coil connected to the furnace? What does SEER mean? Or wondered if you should get a humidifier vs. a dehumidifier? We have those answers.

Let’s start with the heat exchanger, what is it and how do you know if it is having issues? Well the heat exchanger is the most important component of your furnace. It is under extreme high temperatures and it is from the heat exchanger that all the air that comes through your ductwork is heated. That hot air that is formed in the heat exchanger is then blown into the duct work and out the registers. The heat exchanger is actually a set of tubes that are looped repeatedly through the air flow area or cabinet area of your furnace. Different models of furnaces have different types of heat exchangers, but it is the most important part of your homes heating system. If your heat exchanger is cracked, has a hole or some other form of damage of some sort your furnace needs to be replaced. The reasons are very simple, your furnace runs on some sort of combustion from either natural gas or propane, and that combustion or burning can give off harmful gases that are normally contained inside the heat exchanger. If there is a crack or hole, those gases can escape and sicken your family. Regular furnace maintenance is important as your HVAC tech can spot any changes that are taking place in your furnace including the health of the heat exchanger.

The next question is why is the A/C evaporator coil connected to the furnace? It seems a little counterproductive right? The evaporator coil is actually mounted on top or next to the furnace and uses the furnace fan to push the cooler air through the house. It doesn’t actually use the furnace, only the fan. The main work horse of your A/C unit is the compressor which sits outside and pumps the refrigerant through the lines into the coil, the coil then piggybacks off of the furnace fan and cools your home making all the units work in tandem. SEER is a term you may hear when someone is talking about Air Conditioning and you may have wondered what it stands for, it stands for Seasonal Energy Efficiency Rating and in the simplest terms it measures how efficient your Air Conditioning is. The higher the SEER number is the more efficiently your system runs.

Last question, what is the difference between a humidifier and a dehumidifier? Most professionals agree that for good health a Relative Humidity of 30% to 50% in your home is ideal. But how do you go about getting that? Well if you don’t live in an area that has perfect humidity, you can either add a humidifier to your HVAC system or a dehumidifier. If you live in a fairly dry area of the country like the Southwest you might want to add a humidifier, especially as A/C units are very drying. If you live in a very rainy or humid part of the country, such as the Pacific Northwest or the Deep South where the air can drip with humidity you are most likely going to want to install a dehumidifier to remove that excessive humidity from your home. So if the house is too dry add a humidifier, too much humidity, add a dehumidifier.

Spring Cleaning, It's In The Air

Spring Cleaning, It's In The Air

The weather has finally started to act more spring like. The 10 day forecast for the Missoula MT area is forecasting mostly sunny and in the 70’s for the next 10 days and that means there are a lot of folks that are going to be throwing open the windows in their home and thinking about Spring Cleaning. There are some simple and easy things to do now that will make your home cleaner, safer, cooler and more efficient through the hot summer months.

Get your cooling system serviced.

Before you even think about turning on the A/C you should set up an appointment for the system to be cleaned and checked over. Why you ask? Good question, your unit has been turned off for at least 6 months. It sits outside and is open to the elements, unless you have a cover. There are probably bugs, dirt and other debris inside the condenser unit that could impede the fan from operating properly. It is always good to have the unit looked over for leaks or pin sized holes that can allow the refrigerant to escape. It’s a good time to change the air filter as well. I can attest that about 75% of the service calls we get in the early spring and summer months that are about an A/C not cooling are due to a plugged filter. Your HVAC system cannot get proper air flow through the unit if the filter is plugged and no air flow means no cool air to your home.

Check your windows.

Spring Cleaning is the time to clean your home’s windows and it also is a good time to inspect them for cracks in the caulking and check for holes in the screen. Making sure your screen is free of holes will help keep bugs and dirt particles out. Fixing cracked, loose and missing caulk can help stop air leaks.

Check for Mold or Mildew.

If you have an area that has mold or mildew growth you may have a water leak have leak somewhere. Mold and mildew will have an impact on the quality of your indoor air. Too much humidity in your home can be a problem as well. Humidity should stay between 30 to 50% to ensure healthy air quality. If you have too much humidity you can run the A/C or consider installing a dehumidifier. Although here in Montana at our elevation we are more likely faced with needing to add humidity to our homes as too little can be a health issue as well. Regardless, your HVAC contractor can help you figure out what is best for your home and family’s comfort.

Getting your cooling system cleaned and ready in addition to a day spent cleaning and inspecting your homes interior and exterior can payoff of during the long and hot summer and help prevent unexpected issues during the time you would rather be playing. Don’t neglect your HVAC system.

Mold And How It Affects Indoor Air Quality

Mold And How It Affects Indoor Air Quality

Air Quality Mechanical: Missoula, MT

In our last blog we wrote about how chemicals or VOCs can impact indoor air quality and today’s post will be about the role mold has on indoor air quality. There are three fairly common types of indoor mold:

Cladosporium
Stachybotyrs atra ( also known as black mold)
Aspergillus family of molds

Aspergillus is the most allergenic mold type, found on foods and in A/C systems. Cladosporium is the small dots in green or black that are found around toilets, sinks and bath tubs, acrylic painted surfaces and fiberglass air ducting. Stachybotyrs atra is the black mold that generally grows in warm, humid areas where water has leaked. You may have noticed a theme with types of mold that were listed. Moisture. Warmth. Humidity. The EPA has right on the top of their webpage regarding mold: The Key to Mold Control is Moisture Control and below are the top ten things that the EPA thinks you should know about mold.

Potential health effects and symptoms associated with mold exposures include allergic reactions, asthma and other respiratory complaints.
There is no practical way to eliminate all mold and mold spores in the indoor environment; the way to control indoor mold growth is to control moisture.
If mold is a problem in your home or school, you must clean up the mold and eliminate sources of moisture.
Fix the source of the water problem or leak to prevent mold growth.
Reduce indoor humidity (to 30-60%) to decrease mold growth by:
Venting bathrooms, dryers and other moisture-generating sources to the outside
Using air conditioners and de-humidifiers
Increasing ventilation
Using exhaust fans whenever cooking, dishwashing and cleaning
Clean and dry any damp or wet building materials and furnishings within 24-48 hours to prevent mold growth.
Clean mold off hard surfaces with water and detergent, and dry completely. Absorbent materials such as ceiling tiles, that are moldy, may need to be replaced.
Prevent condensation: Reduce the potential for condensation on cold surfaces (i.e., windows, piping, exterior walls, roof, or floors) by adding insulation.
In areas where there is a perpetual moisture problem, do not install carpeting (i.e., by drinking fountains, by classroom sinks, or on concrete floors with leaks or frequent condensation).
Molds can be found almost anywhere; they can grow on virtually any substance, providing moisture is present. There are molds that can grow on wood, paper, carpet, and foods.

Those are all great things to know but what can an HVAC company like Air Quality Mechanical do to help with some of those issues? We can clean your whole HVAC system. That means your furnace, A/C and your duct work. By doing that we can make sure you have a clean filter. If you have a high efficient furnace moisture can collect in the condensate tubes and collection box, we clean that. Your A/C has coils where condensation builds up. Where condensation builds up so does dirt, gunk and mold. We vacuum and clean all of the duct work, removing dust, dirt and dander. A short explanation for all the ways that having a clean system can help your indoor air quality and fight mold growth. Added benefit from having a clean system is that it runs much more efficiently saving you energy costs. If you would like more information give us a call at the office at 406-721-7018. We will also be at the 36th Annual Missoula Home and Garden show on April the 2nd and 3rd. Come talk to us about your concerns and see a demo of our duct cleaning machine.

Indoor Air Quality

You have found Air Quality Mechanical’s first official blog entry.

Did you know that indoor air quality can be 2 to 5 times more polluted than the air we breathe outside? So what pollutes our Indoor Air? There are 4 components that contribute to polluted indoor air:

Chemicals or VOCs
Mold
Particulates or dirt being tracked in or circulated through your HVAC system
Poor ventilation or an HVAC system that is over insulated and too tight, meaning there is no fresh outdoor air coming in to help freshen the over circulated indoor air

If we wrote about each one in this very first blog you would still be reading 3 days from now. That is how much information there is to share. So we are going to break it down into bite-sized bits and start with what Chemicals or VOCs contribute to unhealthy indoor air and a few easy ways to make a difference in your home.

On our Facebook page we have been posting about VOCs or Volatile Organic Compounds and what they are. There are lots of ways to define what a VOC is but the easiest is; they are organic chemicals that have a high vapor pressure at ordinary room temperature (Wikipedia). There are tons of types but most are either man made or ones that occur in nature. The human-produced type are generally the ones that cause indoor air quality and health issues. But VOCs are also a way for plants to communicate with each other and as a way for plants to communicate with animals and bugs. We have also been posting on Facebook about house plants that can combat VOCs but today we will get more in depth and tackle a couple of chemicals that are found in 75 to 95% of household cleaning products, paints and so much more. If you search the internet you can find recipes for household cleaners and detergents to help reduce some of the chemicals and we will give you the names of a few plants that you can incorporate into your home, even a couple that the darkest of black thumbs can rarely kill.

Two of the most common compounds are Formaldehyde and Benzene. We will try to simplify what these chemicals are and some of the products they are used in. Formaldehyde and benzene are both found in the items listed below, but please understand that this is in no way a complete list, but instead just some items commonly found in homes.

Detergents-dish, laundry and hand soap.
Fragrance products that are under pressure and in aerosol form.
Fragrant candles, oils and melting wax scent products.
Fabric softeners in sheet, liquid and pellet forms.
Styrofoam packing materials and packing peanuts.
Glues—epoxy, Super Glue and glue.
Adhesives—Tape, packing tape, adhesive strips and even the adhesive on sticky notes.
Household cleaning products including Oven Cleaners, Bathroom & Kitchen Cleaners.
Tobacco smoke especially when exhaled has a large amount of benzene.

If you “sniff” around on the Internet there are tons of DIY recipes for household cleaners as well as commercially made products. Pinterest is a great source for a lot of information. If shopping at the grocery store make sure to read the ingredients and look for the EcoLogo which was created by the Federal Government in 1988. There are some 7,000 approved products out there. Just a few small changes like changing your laundry detergent and some household products can help to rid your personal environment of a lot of toxins.

Another way to help clean up your indoor air quality is to add a few plants to your home. Aloe Vera absorbs a lot of formaldehyde and loves a warm, sunny kitchen window ledge. It is also great for the occasional kitchen burn or sun burn. Spider plants are so hardy, they are almost impossible to kill and suck up a lot of VOCs. The Snake plant, aka Mother-in-Law’s Tongue is a great plant to have in your bedroom as it needs very little direct sunlight and at night it absorbs carbon dioxide and releases oxygen, helping make your nighttime ZZZs a little healthier. Bamboo palms need little care and are great humidifiers. They do well in shady areas and eliminate a lot of benzene and carbon dioxide. For some pretty additions you can ask at your local nursery for Gerber daisies and Chrysanthemums. You just want to be sure to ask for the household variety, not the garden variety.

So now that you are taking the initiative to keep your indoor air quality healthier don’t forget that the easiest way is by changing your HVAC system air filter and by doing that monthly you won’t have to make your own laundry detergent or sleep with a Snakes Tongue unless you want to. Keeping your home’s HVAC system clean is vital to your indoor air quality. It really is the “lungs” of your home. Keep your filters changed on a regular basis, get your furnace and A/C cleaned yearly and if you have a family member with breathing problems getting the duct work cleaned every few years will help immensely.

Sometimes it can be overwhelming but these are small changes you can make for you and your family. Keep checking back as we will keep posting great ideas.
