How often should you change your air filter?

Did you know that changing your HVAC filter can help improve the efficiency of your HVAC equipment up to 15%?  You heating and cooling unit makes up approximately 50% of your energy bill so by changing your filter on a regular basis, your $200 month bill could be lowered by $15 to $30 a month.  Not bad!
How do you determine when your filter needs changing?

  • Do you have pets? You should consider changing the filter monthly unless the pet is a fish.
  • What is the current air quality? If you have allergies, change the air filter monthly to keep the air fresh and clear.
  • How many people live in your home? More people = more dust that is flying around.  If you live alone with no pets, you can change seasonally.
  • Get in the habit of checking your filters at the beginning of every month. Temperature and seasons effect the dust collection of the filter.
