3 Ways to Make Your Furnace Heat with Less Noise

November 09, 2020

As your furnace starts up and prepares to warm up your home, it’s normal for it to produce some noise. These sounds, like the burners igniting and the blower operating, are all part of the usual start-up procedures.

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

1. Request Annual Furnace Maintenance

Furnace maintenance is very important, since it keeps your manufacturer warranty in place. This helps shield you if something big malfunctions in your furnace during your warranty range.

It can also help our professionals find minor troubles that can make your furnace noisy. And potentially help you sidestep a malfunction on the coldest day of the year. The Indoor Air Quality Association reports that annual maintenance can lower your likelihood of furnace breakdowns by up to 95%.

If little furnace issues are left ignored, they could lead to a malfunction down the road. By finding these issues early, our professionals can get your furnace fixed before heating season is in full swing.

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

2. Routinely Put in a New Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off too frequently. Referred to as short cycling, this can cause your furnace to consume extra gas and make it wear out faster.

Our advice for installing a new furnace filter:

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

You could have to replace your filter more frequently if you have allergies or pets.

3. Get in Touch with Keystone Heating & Air Conditioning Co., Inc When Your Furnace is Making Weird Noises

Some furnaces, particularly older ones, may make more noise than others. But if you’re detecting extremely loud or strange noises, you should get in touch with a heating and cooling company like Keystone Heating & Air Conditioning Co., Inc for furnace repair in Racine.

Here are several noises to be looking for, how to take care of them and when to call a pro.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s since they emit fumes dissimilarly older furnaces, and the process can produce some moisture. If your furnace is having difficulties draining this water, it can make gurgling or bubbling sounds. You’ll want skilled help for this trouble, since it can be created by a blocked drain pipe or clogged drain pan.

Furnace Making Banging Noise

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

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

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

If you’ve neglected regular service for your furnace and you’re hearing this noise, give Keystone Heating & Air Conditioning Co., Inc a call at 262-358-9468. Our heating professionals will get your furnace tuned up and ensure it’s working properly.

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

We recommend first checking your furnace’s air filter and installing a new one if it’s filthy. Next, ensure you don’t have too many vents sealed in your house, as it can throw off air pressure.

If neither of these things fix the issue, your ductwork may 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 issue. This is most often seen with a faltering blower fan motor, which will make an irritating buzzing noise when your furnace starts. It could also mean there’s a problem with the capacitor or transformer. All three of these issues require support from an experienced heating and cooling company like Keystone Heating & Air Conditioning Co., Inc.

Furnace Making Knocking Noise

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

These problems are usually unearthed during yearly maintenance done by a certified HVAC tech. So, while we’re at your home working on repairs, don’t forget to inquire about scheduling your maintenance appointment for the upcoming year.
