3 Ways to Make Your Furnace Run Less Noisily

November 09, 2020

As your furnace starts up and begins to add warmth to your home, it’s expected for it to create some noise. These sounds, such as the burners firing up and the blower operating, are all part of the normal start-up steps.

But there are several approaches you can do to make your furnace less noisy this winter.

1. Schedule Regular Furnace Maintenance

Furnace maintenance is extremely important, as it keeps your manufacturer warranty in place. This helps shield you if something big goes wrong with your furnace during your warranty period.

It can also help our pros spot small troubles that could make your furnace annoying. And possibly help you avoid a breakdown on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can lower your chance of furnace meltdowns by up to 95%.

If small furnace issues keep on being ignored, they may cause a breakdown down the road. By finding these issues in advance, our pros can get your furnace taken care of before heating season is in full swing.

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

2. Frequently Change Your Furnace’s Air Filter

Your air filter helps keep your residence’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 use more energy and make it break down more rapidly.

Our suggestions for changing your furnace filter:

  • Flat filter: Monthly
  • Pleated filter: Every three months

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

3. Contact Evenaire Heating & Air Conditioning When Your Furnace is Making Weird Noises

Some furnaces, particularly older ones, can be noisier than others. But if you’re hearing exceedingly loud or strange noises, you should call a heating and cooling company like Evenaire Heating & Air Conditioning for furnace repair in Pflugerville.

Here are a few noises to keep an eye out for, how to fix them and when to contact a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s because they discharge fumes in another way than older furnaces, and the process can make some moisture. If your furnace is experiencing troubles draining this water, it could make gurgling or bubbling sounds. You’ll need pro support for this problem, since it could be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

It’s not a great sign when your furnace is making a banging sound. It can mean several things.

Haven’t requested maintenance this year and your furnace is producing a banging sound when turning on? Its burners may be dirty. Dirty burners can hold up ignition, which causes gas to accumulate in your furnace.

All that accumulated gas can make a banging or booming racket when your furnace ultimately does ignite. But this is more than merely an annoying noise, since the built-up gas is erupting inside your furnace. This can crack your furnace’s heat exchanger and create a life-threatening carbon monoxide leak.

If you’ve neglected annual service for your furnace and you’re noticing this noise, give Evenaire Heating & Air Conditioning a call at 512-355-1482. Our heating professionals will get your furnace tuned up and make sure it’s operating safely.

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

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

If neither of these things take care of the sound, your ductwork might be dirty or undersized, which will call for assistance from a professional HVAC tech.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a sign there’s an electrical problem. This is most frequently seen with a dying blower fan motor, which will produce a loud buzzing noise when your furnace turns on. It may also mean there’s an issue with the capacitor or transformer. All three of these troubles require help from an experienced heating and cooling company like Evenaire Heating & Air Conditioning.

Furnace Making Knocking Noise

If your furnace is making knocking sounds, it’s frequently an indication that an internal component is worn out. This can be anything from a bearing to a belt or the gas valve. It may also be a sign that your burners need cleaning.

These problems are frequently uncovered during yearly maintenance provided by a certified HVAC pro. So, while we’re at your home working on repairs, don’t forget to inquire about booking your maintenance appointment for next year.

Furnace Making Clicking Noise

A clicking sound may mean a couple of things: worn bearings, gas valve problems or ignition problems. All these issues call for skilled support.
