Air filters perform an essential role in your cooling system. However, unlike your air conditioner, which can last upwards of 15 years, an air filter’s lifespan is much shorter. So what do you need to know about performing an air filter replacement and how can your air conditioner benefit from doing it?
As we mentioned in our blog earlier this week, changing air filters is the number one responsibility homeowners have when taking care of their air conditioners. The reasons for this are simple. Your air filter is used to prevent dust and airborne particles from building up on your unit and circulating through your home’s air. Over time, your air filter will get covered with particles and air will have a harder time passing through it.
When your air conditioner’s filter is dirty, your unit has to put in an extra effort to push air through it. This increases energy consumption and operating costs. A dirty filter is also ineffective at removing airborne particles, so those particles can make it past the filter and begin to build up on your unit.
As a rule of thumb, its best to change your air filter once a month. This is especially true during the hottest (and coldest) months of the year because more air will pass through the filter as your HVAC system runs more often. If you’re worried about the condition of your air filter, it never hurts to remove and examine it to check how dirty it is.
When you are choosing a new air filter, ask yourself how satisfied you are with the performance of your current filter. If you want to do more to protect your unit, install a filter with a higher MERV rating. If anyone in your house suffers from asthma or allergies, or if you’re worried about the air quality in your home, it might be time to switch to a home air cleaner.
