How Important Are Air Filters for Your AC?


Your AC is pretty important. It provides cool, refreshing air that keeps you comfortable during the summer months, but it actually does more than that. In fact, there are a few things you need to know about your AC and what it does for your home, and they all relate to the air filter.

Your air conditioning in Oakland does three major things for your home, and without clean air filters, it can’t do its job at all. Clogged, old, and dirty filters can cause bigger problems than you may think, so let’s talk about how you can prevent them by switching out your air filters every 30-60 days.

Air Filters Improve Your Air Quality (and Ability to Sleep)

Breathing in irritants such as dander, dust, and mold spores will impact your ability to breathe. Even if you have otherwise healthy lungs and don’t suffer from conditions such as asthma, your lungs still don’t appreciate the dirty air you’re possibly breathing in.

Your AC air filter pulls in warm air from your home and blows it over the evaporator coil. However, cleaning the air you breathe is just a byproduct of its actual goal: interacting with refrigerant.

When warm air comes through, it impacts how your air conditioner turns refrigerant into vapor and how it cools your home. Bad airflow means bad AC performance, but it also means you’re not trapping as many airborne particles as possible in that air filter.

Your AC Efficiency Improves

When something’s efficient, it just does what it’s supposed to do without anything getting in the way. If only our air conditioners could do that all the time, right?

Dust and debris will impact your AC’s performance, which is why it’s important to have air filters in place to prevent dust and debris from entering the inner workings of your AC.

Some of it gets in, but it’s cleaned off during your annual HVAC maintenance and inspection appointment. Your job is to change out those filters every 30-60 days to limit the amount of debris that makes it into your AC.

Keep Humidity Down

Your AC pulls humidity from the air. It’s important because otherwise, it couldn’t efficiently change the air temperature, but it also does something else for you.

It prevents mold spore growth. RH is a rating called relative humidity, and if your RH rating is above 60%, you run the risk of fostering mold and mildew growth throughout your home.

With unrestricted airflow, your AC can pull all that humidity out of the air without worry. You’re just making sure it does its job when you pop a clean filter in.

Don’t Forget About Your Air Filters

Switch out the air filters in your AC and start reaping the rewards today. Breathe cleaner air, cause less stress on your air conditioner (and wallet), and maintain the perfect level of humidity in your home to keep everything clean and clear.

Now that you know how important it is to switch out your AC filter, let’s talk about how important annual maintenance is. Don’t delay–set up your annual maintenance as soon as possible so you can prevent future problems from popping up.
