You do not want to wake up to a malfunctioning furnace in the middle of a cold, chilly night. There are several causes of furnace failure, ranging from clogged filters to a failing blower motor. In many cases, problems that led to furnace malfunction or failure could have been prevented.

We have compiled a list of some steps you can take to steer clear of expensive furnace repairs. Take a look.

Replace Your Air Filters Regularly

Air filters are one of the most important, and also (ironically) the most ignored parts of furnaces. An air filter plays an important role in improving indoor air quality. It catches debris, dust, dander, and other indoor air pollutants.

Filters become clogged with dust and dirt particles and dander over time. Clogged, dirty filters can affect airflow and increase stress on your furnace. They will make your furnace work harder and longer, and can cut short your system’s service life.

To prevent future issues, replace filters every 90 days. If you have an elderly person, a pet, or a child living at home, change furnace filters more frequently (every 30 days). Replace traditional filters with HEPA filters that trap more than 99 percent of all airborne contaminants (0.3 microns or larger).

Clean Vents and Floor Registers Regularly

Make sure all your vents are at least 75 percent open. Floor registers should be free of debris, pet hair, and dust and dirt.

Contaminants inside your vents can slide inside the ductwork, affecting the efficiency of your system and increasing stress on it.

To prevent performance problems, remove floor registers and vacuum the areas near them. If you live in an old home or can’t remember the last time you had your ductwork cleaned, it makes sense to schedule a duct cleaning.

Keep Up with Maintenance

A poorly maintained furnace will not just consume more electricity, it can also pose risks to human health and safety. There are several compelling reasons to stay on top of preventative maintenance. Regular maintenance prevents problems and can save you headaches and money on furnace repairs down the line. Periodic maintenance will extend the useful life of your furnace.

During a tune-up session, your technician will:

  • Check the heat exchanger to make sure it is working properly
  • Examine and clean the blower
  • Check the air intake grilles and vents
  • Change the air filters
  • Clean the burner
  • Inspect the air handler
