3 Ways to Make Your Furnace Less Noisy

November 09, 2020

As your furnace turns on and gets ready to heat your residence, it’s expected for it to create some noise. These sounds, such as the burners igniting and the blower running, are all part of the normal start-up process.

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

1. Request Annual Furnace Maintenance

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

It can also help us find small problems that could make your furnace annoying. And potentially help you avoid a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that regular maintenance can decrease your chance of furnace malfunctions by up to 95%.

If small furnace issues are left undetected, they may cause a breakdown later on. By discovering these issues early, our technicians can get your furnace taken care of before heating season is underway.

And, most important, professional 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 utility costs, according to the U.S. Department of Energy.

2. Routinely Install 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 often. Called short cycling, this can cause your furnace to eat up more energy and make it break down faster.

Our recommendations for replacing your furnace filter:

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

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

Here are a few noises to keep an eye out for, how to repair them and when to get in touch with a pro.

Furnace Making Gurgling or Bubbling Noise

This noise happens more frequently with high-efficiency furnaces. That’s since they exhaust fumes dissimilarly older furnaces, and the process can produce some moisture. If your furnace is running into troubles discharging this water, it may make gurgling or bubbling sounds. You’ll require experienced support for this issue, since it could be the result of 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 might mean a few things.

Haven’t had maintenance done this year and your furnace is creating a banging sound when starting? Its burners could be dirty. Dirty burners can hold up ignition, which results in gas accumulating inside your furnace.

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

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

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

If neither of these things repair the problem, your ductwork might be dirty or undersized, which will require assistance from a pro HVAC technician.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a flag there’s an electrical problem. This is most frequently seen with a faltering blower fan motor, which will create a loud buzzing noise when your furnace begins to heat. It could also mean there’s trouble with the capacitor or transformer. All three of these issues need support from a professional heating and cooling company like Gillman Heating and Air.

Furnace Making Knocking Noise

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