“Out of sight, out of mind” is often a true condition – but if that means you go too long before changing your air filter, it can lead to some serious problems for your heating and cooling system.
How often should you have “change the air filter” on your mind? Well, that depends on a few factors such as:
Some recommendations for changing air filters are as often as once per month, or once every other month. Rarely should you go longer than once every three months (or, before each new season).
Your air filters perform an important service, keeping particulates out of your indoor air as well as the equipment. When your air filters are dirty, they can’t filter out the dust, pet dander, and other allergens from your indoor air. You’ll begin to notice more dust in the house, and the sad fact is that dirty air is re-circulating through dirty filters.
Over time, your air filter captures a lot of dirt and debris, filling up the fibers and making it difficult for air to flow through. When airflow is obstructed, it requires your system to work much harder to produce the same (and often, uneven) results. You end up using more energy but get less cooled (or heated) air.
Blocked airflow can also lead to frozen condenser coils, causing your AC unit to freeze up and break down, ruining your compressor. Signs that this is a problem include:
If you notice any of these things and you’re in the Phoenix, Arizona area, it’s best to call a trusted HVAC company right away and have them make a professional inspection.
Clean air filters are as crucial to the maintenance of your HVAC equipment as clean oil is for your car’s engine. Protect your investment by keeping your air filters changed regularly.
