November 09, 2020

As your furnace switches on and begins to add warmth to your home, it’s expected for it to produce some noise. These sounds, including the burners firing up and the blower running, are all part of the normal start-up steps.

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

1. Schedule Annual Furnace Maintenance

Furnace maintenance is highly important, as it keeps your manufacturer warranty in place. This helps protect you if something major stops working in your furnace during your warranty period.

It can also help our pros uncover minor issues that could make your furnace noisy. And maybe help you avoid a breakdown on the most frigid day of the year. The Indoor Air Quality Association reports that routine maintenance can decrease your chance of furnace repairs by up to 95%.

If minor furnace troubles keep on being ignored, they may cause an issue down the road. By discovering these issues early, our techs can get your furnace fixed 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 correctly maintained furnace could save up to 30% on your utility expenses, according to the U.S. Department of Energy.

2. Frequently 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. Known as short cycling, this can cause your furnace to eat up extra energy and make it break down more rapidly.

Our recommendations for replacing your furnace filter:

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

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

If neither of these steps take care of the sound, your ductwork could be dirty or undersized, which will call for assistance from a skilled HVAC technician.
