3 Reasons to Change Your Home A/C Air Filter Once a Month

By Judyth Piazza

Incredible Renovations helpful tip of the day:  "Change your air filter once a month to cut down energy cost and prolong the life of your heating and air unit."

Reason #1: Air filters prolong the life of your A/C unit.
Air filters keep harmful particles away from the motor and coil. The blower motor will burn out if not kept clean and could cost you more than $200 to replace and if your coil freezes up it could cost you a whopping $1000 or more for a new compressor.

Reason #2: Air filters cut down on your energy bill
A dirty air filter makes your A/C unit work harder and longer causing your energy bill to increase by 35% or more each month.

Reason #3: Air filters promote better air quality in your home
Changing your air filter one a month will cut down on the airborne particles that cause allergies and viruses..

According to the EPA, “Filters are used to protect the HVAC equipment from the buildup of unwanted materials on the surfaces such as fan motors and heating or cooling coils, and not for direct indoor air quality reasons. They have low efficiency on smaller airborne particles and medium efficiency on larger particles, as long as they remain airborne and pass through the filter. Some smaller particles found within a house include viruses, bacteria, some mold spores, a significant fraction of cat and dog allergens, and a small portion of dust mite allergens.”

A good rule of thumb is to make sure you change your air filter every time you pay your energy bill.

  1. You have a good point in changing the unit every month. But for me, I think cleaning the air filter at least every month is also a quick fix to prolong the life of the A/C unit, cut down the energy bill, and have better air quality inside the house. Three months is usually the lifespan of most air filters. So, if you think that after three months it doesn’t efficiently work anymore, it’s time to look for a new one. ->Oma Gammel
