How Important Is It to Change Your AC Filters?
Rainier Heating & Cooling, LLC • October 20, 2025

Do you remember when you last changed the filter of your air conditioner? If you haven’t changed the AC filter in a while, now is the time to do so.

During your annual maintenance appointment, our technicians at Rainier Heating & Cooling will replace the air filter in your air conditioning system to keep it running as cleanly and efficiently as possible! The air filter plays an essential role in achieving pure air and the home’s desired temperature.

These Are a Few Reasons Why Changing Your Air Conditioning Filter is Imperative.

Clogged Filters Lead to Inefficient Systems.

A clogged air conditioner filter can make your system work harder than necessary, leading to higher energy bills and shortened lifespan of your unit. It is easy and quick to change the air filter, but if it has caused an issue with your system and you need air conditioning replacement in Auburn, contact our trained technicians today!

Health Risks Are Associated With Dirty Air Filters.

Dirty air filters can allow dust, dander, and mold to circulate throughout your home. As a result, you and your members will be exposed to these substances, aggravating respiratory problems, such as asthma and allergies. On the other hand, you and your family will be able to breathe more accessible if you keep your air filter clean.

Your Repair Costs Increase When Your Air Filters Are Dirty.

A clogged air filter can result in expensive AC repairs in Federal Way. In addition, when you ignore your air filter, your unit may stop working altogether because it cannot circulate air properly. If you include air filter changes as part of your routine, you can spend your money on something other than repairing and replacing your HVAC system.

What is The Recommended Frequency of Replacing Your Air Filter?

Depending on the type of filter you are using and the level of demand placed on your filter, the answer may vary. However, changing it every one to three months is generally recommended. If you’re using your air conditioning more often or have allergies, we recommend changing it more often. The same goes for if you have pets or live in a dusty area.
