FAQs

I Need a New Furnace—How Do I Know Which System to Choose?2026-04-28T21:53:31-05:00

In short, let Mueller Heating help you! There are a lot of choices when it comes to a new heating system. But Mueller Heating’s experts work with you to find the best one for your home, needs, and budget. Count on us to walk you through all your options and help you find the right one.

Are High-Efficiency Furnaces Really Worth the Extra Cost?2026-04-28T22:00:49-05:00

Yes! While there may be a larger upfront cost, higher-efficiency systems offset it by using significantly less fuel, lowering your monthly payments. Look for models with 95 percent AFUE or higher for best results.

What Happens During the Installation Process?2026-04-28T22:01:49-05:00

After you call our team and choose your new system, you can sit back and relax while we take care of the work. We start by protecting your floors and shutting off power to your old system. Then, once that unit is removed, we position and level the new furnace, hook it up to your ductwork and utilities, and test it to ensure everything works properly. We finish by cleaning up, returning your home to exactly the way we found it.

What Size Furnace Do I Need for My Home?2026-04-28T22:02:42-05:00

The answer depends on few different factors, the biggest one of which is the size of your home. That’s why our process always begins with measuring your home—so we can be sure your new unit runs as smoothly and efficiently as possible.

How Do I Know If It’s Time for a New Furnace?2026-04-28T22:13:53-05:00

If your system is on the tail end of those 20 years, you should start to consider a new installation. Other signs of needing a replacement include frequent repairs, high energy bills, strange noises or odors, and if the system is blowing cold air.

Why Is My System Constantly Turning On and Off?2026-04-28T22:17:24-05:00

This is known as “short cycling.” It can happen when your air filter is dirty and needs to be replaced, your thermostat is faulty, or your furnace isn’t the right size for your house.

What Does a Yellow Pilot Light Mean?2026-04-28T22:18:13-05:00

Pilot lights should be blue in color. So, if yours is yellow, it usually means a problem with combustion, which could indicate a carbon monoxide leak. If that’s the case, turn the furnace off right away and call our team for repair.

What Are Some Ways I Can Reduce My Heating Costs?2026-04-28T22:19:23-05:00

As we mentioned, furnace maintenance is one of the best and most effortless ways for you to keep your energy costs low. You can also try switching your ceiling fan blade to rotate clockwise (it will move warm air around the room and down to you), lower the temperature when you go to sleep, and sealing any gaps in your windows and doors.

How Long Can I Expect My Furnace to Last?2026-04-28T22:19:37-05:00

The answer depends on how often it’s used and how well you take care of it. But on average, the answer is about 15 to 20 years. To reach the higher end of that range, be sure to schedule routine maintenance once a year. It’ll keep all working parts in good order, improve the furnace’s efficiency, and more.

When Is the Best Time to Change My Furnace Air Filter?2026-04-28T22:19:51-05:00

For optimal airflow and indoor air quality, we recommend switching out filters once every one to three months. However, you may need to change it more often if you have pets, someone in the house smokes, or if a family member has problems with allergies.

What’s Typically Included in Maintenance?2026-04-28T22:20:32-05:00

Our service consists of a multi-point inspection of key components inside your system. We clean the blower assembly, clean and lubricate working parts, and test your thermostat’s calibration. We’ll also check your heat exchanger, burners, and electrical components for cracks and damage, fixing smaller issues before they get worse.

How Often Should I Have My Furnace Serviced?2026-04-28T22:21:07-05:00

Generally, you should schedule maintenance once a year. It will keep all the furnace’s working parts clean and tuned and your system running smoothly.

What Can I Do to Help Maintain My System?2026-04-28T22:21:36-05:00

A few simple steps you can take include replacing your air filters every one to three months, keeping your vents and registers clear of obstructions, and removing any dust or debris from around the furnace.

Are There Ways to Tell If My System Needs Repair Before It Breaks Down?2026-04-29T14:02:12-05:00

Yes! Not every problem starts with a bang. Subtle clues that your furnace could need attention include uneven heating across the house, more dust than usual around the house, and energy bills that suddenly skyrocket.

How Do I Know What Size Air Conditioner I Need?2026-04-28T22:25:14-05:00

In short, Mueller will tell you! We start our installation process by first understanding your home’s size and layout. That helps us find the right system size. It’s a crucial step, as a unit that is too large will short-cycle (constantly turn on and off) and one that’s too small will run non-stop. Both can waste energy and cost you in terms of your utility bills.

How Long Does an AC Installation Usually Take?2026-04-28T22:25:43-05:00

Most ACs usually take anywhere between six and 10 hours to install.

What Can I Expect on Installation Day?2026-04-28T22:26:20-05:00

Our team of installers starts by removing your old system and setting your new one on a level pad. Then we install the indoor coil, run new refrigerant lines, and hook up wiring. Once all that is completed, we test the system to make sure it runs—then answer any questions you have about your new AC.

What Do I Do About Ice on My Air Conditioner?2026-04-28T22:27:30-05:00

If your system has ice on it, call Mueller Heating for help. Ice usually means either the AC is low on refrigerant, a fan inside the system isn’t running properly, or there’s a problem with air flow. Our techs can diagnose the problem and fix it to keep you comfortable all summer long.

How Do I Know Whether I Need to Repair or Replace My AC?2026-04-28T22:27:52-05:00

Most of the time, a repair is the best—and least expensive—option. However, if a fix is too costly or unsafe to make, we usually recommend a new installation. Other major indicators that you need a new system include old system age (older than 10-15 years) and consistently high energy bills.

My AC Is Not Blowing Cold Air—What Should I Do?2026-04-28T22:28:47-05:00

If your system is running but not blowing cold air, a dirty air filter or a clogged outdoor condenser could be to blame. Try replacing your filter first. If that doesn’t solve the issue, give our team a call.

What Is Causing My Unit to Make Screeching or Buzzing Sounds?2026-04-28T22:29:25-05:00

Sounds like these indicate problems with parts inside your AC. A high-pitched squeal, for example, could mean the fan belt has slipped or is worn out. Buzzing or clicking, on the other hand, could be caused by a failing electrical component. If you hear odd noises coming from your system, be sure to give us a call right away.

How Long Does a Typical AC Repair Take?2026-04-28T22:30:02-05:00

It depends on how severe the problem is. Many common repairs, like replacing electrical components or cleaning drains, take only a few hours. However, if the problem is more extensive or a specific part needs to be ordered, it may take longer.

Is Your Air Conditioner Maintenance Really Necessary?2026-04-28T22:30:33-05:00

Yes! Not only will your system lifespan be longer with routine service, but you can also reduce your energy consumption and prevent costly repairs down the road. It’s a simple service that helps preserve your AC. Try to schedule maintenance every year in the summer for best results.

Are There Other Ways to Save on Energy in the Summer?2026-04-28T22:30:45-05:00

Absolutely. Opening your windows for fresh air (and turning off your air conditioner) is a common one. However, if it’s too hot outside to open windows, consider turning down the AC and switching your ceiling fans to rotate counterclockwise to keep cool air flowing. You can also schedule AC maintenance to improve energy efficiency, close curtains during the day to keep out the warm sunlight, and install a programmable thermostat to schedule temperature changes and minimize energy usage.

Will Running My Air Conditioner Help With Humidity?2026-04-28T22:31:30-05:00

It will, but you may not want to rely solely on your AC for that. A dehumidifier is a better solution, as it is designed to remove excess moisture in the air. Running a dehumidifier can also help your home feel cooler, meaning you can use it in place of your AC (to a degree) and save on energy usage that way.

I Just Replaced My AC—Do I Really Need Maintenance?2026-04-28T22:32:09-05:00

Yes, you do. Not only will service keep that new system in pristine condition, but it will also keep your warranty valid in case a bigger problem comes along down the road.

How Long Does an Appointment Usually Take?2026-04-28T22:32:48-05:00

Typically, our thorough cleaning and tuning takes anywhere from one hour to 90 minutes. For older systems, or those that haven’t been serviced in a while, an appointment could take longer.

Does Maintenance Help With Allergies?2026-04-28T22:33:20-05:00

It can. Components inside your AC can get dirty with dust, pollen, and mold during the season. Our techs will clean all that away and also replace your air filter, all of which will help improve your indoor air quality and reduce the circulation of allergens.

How Can I Tell If My Air Quality Is Poor?2026-04-28T22:34:22-05:00

Some signs you can see, such as visible dust buildup, mold, or mildew. Others you’ll be able to feel, such as fatigue, headaches, or sudden allergy symptoms. Booking a consultation with Mueller can help reveal what’s causing those problems.

What Are Common Indoor Pollutants?2026-04-28T22:34:53-05:00

Dust and dirt are two of the most common culprits of poor air quality. Pet dander, pollen, and mold spores can also cause issues, as well as cleaning products and paints. Others, such as radon or carbon monoxide, are not as common but are more serious. It’s best to have a professional help you determine where you need help.

How Can I Improve Ventilation in My Home?2026-04-28T22:35:32-05:00

Energy recovery ventilators are a great option. They work by exchanging stale indoor air for fresh outdoor air. That incoming air is also conditioned and filtered of pollutants. An air purifier will also help you by capturing and killing airborne contaminants.

Do I Need an Air Purifier or a Humidifier?2026-04-28T22:36:16-05:00

Both systems work differently and can help you in different ways. Purifiers work by capturing and killing airborne pollutants while humidifiers add moisture to your air, helping eliminate dryness and making your home feel warmer. For best results, try using them both together.

Does Cleaning My Ducts Really Help With Allergies?2026-04-28T22:36:53-05:00

Yes! It’s common for dust, dirt, and pet dander to accumulate inside your ducts. Having them cleaned out every three to five years can boost your air quality and keep the sneezing to a minimum.
