As your furnace starts up and prepares to warm up your house, it’s normal for it to create some noise. These sounds, such as the burners lighting and the blower operating, are all part of the typical start-up process.

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

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

If minor furnace problems keep on being undetected, they could result in a malfunction down the road. By finding these problems in advance, our technicians can get your furnace taken care of before heating season is in full swing.

2. Routinely Replace Your Furnace’s Air Filter

Your air filter helps keep your home’s air fresh and clean. When it turns too clogged, it can make your furnace turn on and off too frequently. Called short cycling, this can cause your furnace to eat up more gas and make it stop working more rapidly.

Our advice for installing a new furnace filter:

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

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