How Pets and Pet Hair Can Affect Your AC System's Performance

January 6, 2025

Understanding the Impact Pets Have on Your Cooling System

Beyond the indoor air quality considerations that come with pet ownership, pet hair and dander can also directly affect the performance and longevity of your air conditioning equipment itself. Old Glory Air Conditioning and Heating explains what pet owners should know.

Faster Filter Clogging

Homes with pets typically experience faster air filter clogging compared to pet-free households, since pet hair and dander add to the particulate load your filter needs to capture. A clogged filter restricts airflow, forcing your system to work harder.

Increased Strain on the Blower Motor

When filters become clogged more quickly due to pet hair, the reduced airflow can place additional strain on your system's blower motor as it works harder to move air through the restricted filter, potentially accelerating wear over time.

Pet Hair Accumulation Within the System Itself

Beyond the filter, pet hair can sometimes make its way past filtration and accumulate on internal components like the blower wheel, which can affect airflow and efficiency if not addressed during regular maintenance visits.

The Importance of More Frequent Filter Changes

Given the additional debris load, homes with pets generally benefit from checking and replacing air filters more frequently than the standard recommendation, helping maintain proper airflow and reduce strain on system components.

Considering Filter Types Designed for Pet Owners

Certain air filters are specifically designed with pet owners in mind, offering enhanced capture of pet hair and dander while still maintaining adequate airflow for your system's needs.

Outdoor Unit Considerations for Pet Owners

For households with outdoor pets, it's worth ensuring pets don't have direct access to dig near or damage the outdoor condenser unit, and that pet waste is kept away from this equipment for both system health and pest control reasons.

Signs Pet Hair May Be Affecting Your System

Reduced airflow from vents, a system that seems to run longer than usual to reach the set temperature, or visible pet hair accumulation around vents and filters are all signs that pet hair may be impacting your system's performance.

How Regular Maintenance Helps

Routine professional maintenance visits provide an opportunity to check for and address any pet hair accumulation within the system that goes beyond what filter changes alone can catch.

Balancing Pet Ownership With System Care

With consistent filter changes and regular maintenance, pet owners can absolutely maintain both a happy home for their furry companions and a well-functioning, efficient air conditioning system.
