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

But there are a couple of approaches you can do to make your furnace quieter this winter.

1. Book Annual Furnace Maintenance

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

It can also help our pros uncover minor problems that might make your furnace noisy. And potentially help you prevent a malfunction on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can lower your probability of furnace repairs by up to 95%.

If small furnace issues are left undetected, they could cause a malfunction in the future. By discovering these problems early, our professionals can get your furnace taken care of before heating season is underway.

And, most critical, specialized cleaning and lubrication of your furnace’s moving components 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. Frequently 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 additional fuel and make it wear out more quickly.

Our recommendations for replacing your furnace filter:

  • Pleated filter: Every three months

You may have to install a new filter more frequently if you have allergies or pets.

Furnace Making Gurgling or Bubbling Noise

If your furnace is running into difficulties discharging this water, it might make gurgling or bubbling sounds.

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

If neither of these things take care of the issue, your ductwork might be dirty or undersized, which will require assistance from a pro HVAC specialist.

Furnace Making Humming or Buzzing Noise

If your furnace is buzzing or humming, it’s a symptom there’s an electrical issue.
