dirty filters

Even though it’s only February, it’s still never too early to start thinking about springtime allergies and changing the air filters in your home. In fact, for many allergy sufferers, “allergy season” has become year-round. Depending on which filters you use in your home, most manufacturers of the standard 1″-3″ air filters direct you to change them every 30-60 days. The average length of time between changes for the “average” home under these circumstances is:

  • Without any pets: every 90 days
  • With a dog or cat: every 60 days
  • With multiple pets: every 20-45 days
  • Someone in the home has allergies: every 20-45 days
  • Vacation home or single occupant and no pets or allergies: every 6-12 months


Other factors that may influence how often your air filters need changing include:

  • the type of air filter you are using
  • the overall indoor air quality
  • the number of people living in the home
  • the level of air pollution around the home (i.e., from highways and high traffic areas, construction, dust storms, allergenic vegetation)


Goettl’s offers an ESA (Energy Savings Agreement), which includes changing standard 1” filters during the twice annual maintenance visits. For homes with high efficiency filtration systems, there is a modest cost in addition to the ESA, depending on the efficiency level and thickness of the filter used. So, skip the hassle, and avoid the possible danger of getting up on a tall ladder.

Call Goettl’s [928.567.2200 or 928.772.2751] to sign up for an ESA based on your home’s needs. You’ll be glad you did!
