How Often Should You Change Air Conditioning Filters

Air conditioning units are pivotal in maintaining a healthy, comfortable indoor environment. Yet, an often-overlooked aspect of air conditioner maintenance is the regular replacement of air conditioning filters. 

This article will shed light on the integral role of air conditioning filters. We will delve into the lifespan of filters, the factors that can impact this lifespan, and the implications of failing to replace these crucial components. 

Understanding Your Air Conditioning Filters

Air conditioning filters are crucial components of your air conditioner. They’re essentially barriers that filter out dust, allergens, and other pollutants from the air.

Why are they important?

They keep your indoor air clean, providing you with a healthier environment. Plus, they prevent these particles from damaging the internal components of your AC system. Without a functioning filter, your air conditioning system would be exposed to debris that could impair its operation.

The Lifespan of an Air Conditioning Filter

A typical air conditioning filter lasts between 60 to 90 days when they are either replaced or cleaned.

Factors Affecting Lifespan

Your filter’s lifespan will depend on the filter type, air quality, usage, and pets. If you live in a polluted location or your pet sheds, you may need to change your filter more often.

How Often Should You Change Your Filter?

As a general rule, most experts recommend changing your air conditioning filter every 60 to 90 days. This guideline is applicable for a typical suburban home with no pets.

Specific Situations

Your filter might need to be changed more frequently if you have pets or someone in your home has allergies. If you’re using your AC more heavily, like in the peak of summer, it’s advisable to check the filter every month.

How to Change Your Air Conditioning Filter

Changing an air conditioning filter is a simple task. First, turn off your AC system. Once you’ve located the filter, slide the old one out and replace it. Make sure the new filter is placed in the correct direction (it’s usually marked on the filter).

Safety Precautions

While changing the filter, remember to wear gloves and a mask, as the old filter might be loaded with dust and allergens.

The Impact of Not Changing Your Filter


Not changing your AC filter can impact the efficiency of your system. A clogged filter makes the AC work harder, which leads to reduced performance or worse a breakdown.


Moreover, an overworked AC system uses more energy, leading to higher electricity bills. Also, neglecting to change the filter could lead to costly repairs in the long run.

Final Thoughts

Taking care of your air conditioning unit goes beyond the occasional servicing. Regularly replacing your AC filter is integral to maintaining your system’s efficiency, contributing to cleaner indoor air and a healthier home environment. Moreover, it can prevent unnecessary strain on your AC unit, ultimately reducing energy consumption and prolonging the lifespan of your system. Remember, regular maintenance can prevent costly repairs down the line.
