The Number One Thing to Do for Your Furnace: Filter Maintenance

Changing your filter is the most important thing to do to ensure your furnace and air conditioner’s longevity and performance. Save 5% or more on energy costs by changing the filters regularly. 

One of the biggest culprits behind equipment issues are dirty filters which can:

  • Restrict airflow, which puts additional strain on the fan motor that after time can make your motor burn out, your system overheat or your equipment fail.
  • Force your fan motor to overwork which uses more energy, can cause damage to your system and significantly raises your utility bill.
  • Drastically reduce your indoor air quality which can aggravate allergies, asthma and other illnesses.
  • Clog ductwork with debris which can decrease your equipment’s life span and lead to costly repair or replacement expenses.

The filter should be replaced every one to three months, unless otherwise instructed by the manufacturer of the furnace. Homes with smokers or pets will likely need to change their filters more regularly than other households. If you are changing it every 3 months and noticed that it is clogged, shorten the time between changes.

Set a date on the calendar or put a reminder on your phone to easily remember when the filter should be changed. Some homeowners also find it easier to simply replace the filter on the first day of every month. In addition to the filter, you should keep the area around the furnace clean and free of obstructions, especially combustible materials. This allows the furnace to run properly and avoid potential damage to the unit, its performance or your home.
