Make Your Furnace Operate More Quietly with These 3 Approaches

November 09, 2020

As your furnace turns on and gets ready to heat your home, it’s expected for it to produce some noise. These sounds, including the burners igniting and the blower running, are all part of the usual start-up process.

But there are a couple of steps you can do to make your furnace run more quietly this winter.

1. Book Yearly Furnace Maintenance

Furnace maintenance is highly important, because it keeps your manufacturer warranty valid. This helps shield you if something big goes wrong with your furnace during your warranty range.

It can also help our professionals find minor problems that can make your furnace annoying. And maybe help you avoid a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that annual maintenance can decrease your chance of furnace repairs by up to 95%.

If minor furnace issues keep on being undetected, they can lead to a breakdown later on. By finding these issues in advance, our techs can get your furnace repaired before heating season is underway.

And, most important, specialized cleaning and lubrication of your furnace’s moving parts 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. Routinely Change Your Furnace’s Air Filter

Your air filter helps keep your house’s air fresh and clean. When it becomes too filthy, it can make your furnace turn on and off too frequently. Referred to as short cycling, this can cause your furnace to eat up additional fuel and make it break down more quickly.

Our suggestions for changing your furnace filter:

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

You may have to change your filter more regularly if you have allergies or pets.

3. Get in Touch with PWA Heating & Cooling Inc When Your Furnace is Creating Weird Noises

Some furnaces, especially older ones, might be noisier than others. But if you’re noticing very loud or strange noises, you might need to contact a heating and cooling company like PWA Heating & Cooling Inc for furnace repair in Plainfield.

Here are several noises to be on the lookout for, how to repair them and when to get in touch with a specialist.

Furnace Making Gurgling or Bubbling Noise

This noise occurs more commonly with high-efficiency furnaces. That’s since they discharge fumes differently than older furnaces, and the process can create some moisture. If your furnace is experiencing difficulties discharging this water, it might make gurgling or bubbling sounds. You’ll need pro support for this issue, since it can be the result of 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 can mean several things.

Haven’t scheduled maintenance this year and your furnace is creating a banging sound when starting? Its burners might be dirty. Dirty burners can hold up ignition, which causes gas to accumulate within your furnace.

All that accumulated gas can create a banging or booming noise when your furnace finally does ignite. But this is more than just a bothersome noise, since the accumulated gas is exploding within your furnace. This can crack your furnace’s heat exchanger and make a life-threatening carbon monoxide leak.

If you’ve neglected annual tune-ups for your furnace and you’re hearing this noise, give PWA Heating & Cooling Inc a shout at 815-410-1231. Our heating professionals will get your furnace tuned up and double-check it’s working safely.

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

We recommend first inspecting your furnace’s air filter and replacing it if it’s dirty. Next, ensure you don’t have too many vents sealed in your home, as it can throw off air pressure.

If neither of these methods fix the sound, your ductwork could be dirty or undersized, which will be a need for assistance from a skilled HVAC technician.

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 annoying buzzing noise when your furnace turns on. It could also mean there’s an issue with the capacitor or transformer. All three of these problems call for assistance from a skilled heating and cooling company like PWA Heating & Cooling Inc.

Furnace Making Knocking Noise

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

These troubles are usually unearthed during annual maintenance provided by a certified HVAC tech. So, while we’re at your residence performing repairs, don’t forget to check with us about scheduling your maintenance appointment for the upcoming year.

Furnace Making Clicking Noise

A clicking sound might be the result of things: worn bearings, gas valve troubles or ignition issues. All these problems require skilled assistance.
