As your furnace turns on and begins to warm up your home, it’s expected for it to make some noise. These sounds, like the burners igniting and the blower running, are all part of the usual start-up procedures.

But there are several things you can do to make your furnace quieter this winter.

1. Request Annual Furnace Maintenance

Furnace maintenance is extremely important, because it keeps your manufacturer warranty ongoing. This helps defend you if something major stops working in your furnace during your warranty range.

It can also help our pros discover little issues that might make your furnace noisy. And possibly help you avoid a meltdown on the chilliest day of the year. The Indoor Air Quality Association reports that regular maintenance can lower your chance of furnace malfunctions by up to 95%.

If minor furnace troubles go ignored, they may lead to trouble in the future. By uncovering these problems sooner, our pros can get your furnace taken care of before heating season is at its peak.

And most essential, pro cleaning and lubrication of your furnace’s moving pieces can help make it more efficient. A properly maintained furnace could save up to 30% on your gas costs, according to the U.S. Department of Energy.

2. Regularly Replace Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it turns too filthy, it can make your furnace turn on and off too often. Known as short cycling, this can cause your furnace to consume additional fuel and make it break down faster.

Our recommendations for replacing your furnace filter:

  • Flat filter: Once a month
  • Pleated filter: Every three months

You might have to get a new filter more often if you have allergies or pets.

3. Call Arizona Comfort Systems When Your Furnace Is Creating Weird Noises

Some furnaces, particularly older ones, might be louder than others. But if you’re detecting extremely loud or weird noises, you should contact a heating and cooling company like Arizona Comfort Systems for furnace repair in Sierra Vista.

Here are a couple of noises to be looking for, how to fix them and when to contact a pro.

Furnace Making Gurgling or Bubbling Noise

This noise is more common with high-efficiency furnaces. That’s because they exhaust fumes in another way than older furnaces, and the process can create some moisture. If your furnace is experiencing difficulties draining this water, it can make gurgling or bubbling sounds. You’ll want professional support for this issue, since it may be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a great thing when your furnace is making a banging sound. It may mean a few things.

Haven’t scheduled maintenance recently and your furnace is producing a banging sound when turning on? Its burners could be dirty. Dirty burners can hold up ignition, which leads gas to accumulate in your furnace.

All that accumulated gas can cause a banging or booming noise when your furnace eventually does ignite. But this is more than merely an irritating noise, as the increased gas is igniting within your furnace. This can damage your furnace’s heat exchanger and cause a dangerous carbon monoxide leak.

If you’ve neglected regular service for your furnace and you’re detecting this noise, give Arizona Comfort Systems a ring at 520-415-5681. Our heating professionals will get your furnace tuned up and ensure it’s operating correctly.

Your ductwork can also create banging sounds when your furnace turns on, because the metal is expanding and contracting.

We advise first looking at your furnace’s air filter and getting a new one if it’s clogged. Next, make sure you don’t have too many vents closed in your home, as it can make air pressure uneven.

If neither of these methods repair the sound, your ductwork might be dirty or undersized, which will call for assistance from a pro HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s electrical troubles. This is most usually seen with a faltering blower fan motor, which will produce an irritating buzzing noise when your furnace begins to heat. It might also mean there’s trouble with the capacitor or transformer. All three of these problems need support from a professional heating and cooling company like Arizona Comfort Systems.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s usually a symptom that an internal component is going out. This could be anything from a bearing to a belt or the gas valve. It might also be a symptom that your burners need to be cleaned.

These issues are typically uncovered during regular maintenance done by a certified HVAC professional. So, while we’re at your home performing repairs, don’t forget to ask us about booking your maintenance appointment for the future.

Furnace Making Clicking Noise

A clicking sound can be the result of things: worn bearings, gas valve troubles or ignition problems. All these problems need specialized assistance.
