When To Change Filters

To ensure that your air quality remains at its best, it’s important to change your air filters regularly. Switching out your air filters keeps your HVAC unit working its best and will even lower your monthly energy bills. How often you should change the filters in your furnace depends on the type of filter you use and how efficient the filter is.

Fiberglass vs Pleated Filters

  • Fiberglass filtersare an affordable disposable option but must be changed at most, every 30 days.
  • Pleated filters are also disposable. However, they also last longer than fiberglass filters and are generally more efficient. Depending on the season, you should replace these filters within 90 days.

Other Factors to Consider

Location, Location Location

Depending on where you live, you may not have to use your HVAC system throughout the day. If you’re using your filter for no more than five hours per day, you can extend the use of your filter by a few months.

Season of the year

HVAC systems operating during peak summer and winter months will need to be changed every 30 days. Other times of the year only require that filters be switched out approximately every 90 days. Peaks season is when your system is working its hardest to keep the temperature inside of your home comfortable for you and your guests. Make sure you switch out your filters on schedule so that your HVAC system can continue operating at maximum efficiency.

Size of Home

Larger homes need HVAC filters changed more frequently since the furnaces and air conditioners are filtering more air particles and pollutants than smaller homes.

Allergies

If you’re an allergy sufferer, then changing your filters regularly is extremely important. It is highly recommended that you switch them out every 30-45 days.

Family and Pets

If you have children in your home, you should change your air filter more frequently to prevent harmful particles from potentially making your family sick. Change your filter every 60-90 days. For homes with pets, replacing your filter every 30-45 days is recommended.

Home Air Quality 

If your home doesn’t have the best air quality, you should be changing your air filters more often. To ensure your HVAC system is operating as efficiently as possible, proper maintenance of your system should be a top priority.
