Does My Pet Impact the HVAC System in My Home?

Pets can impact your HVAC system with the dandruff they produce and the way they chew. Read on to find out how pets inside your in Hillsborough, NC, home can affect your HVAC system.

Dirt and Debris

Because pets generally need to go outside, they can track dirt and debris into your home. This can block the vents and clog your air filters, which can thereby cause damage to the HVAC system.


Another way in which having pets can damage your HVAC system is through shedding. Even animals generally considered to be hypoallergenic may shed a little bit. This, too, can clog the air filters and vents in your unit.


Many pets have an obsession with chewing, and sometimes they may deviate from their usual toy selection to go for exposed wires. If your pet goes after HVAC wires in your home, that would be catastrophic for both your pet and the system.

Pet Dander

Another important issue is pet dander. Because many pets tend to lick themselves, there may be dried saliva mixed together with pet dander collecting in the air ducts in your home. This can irritate people who are prone to allergies.

What Can You Do for Your Pet and HVAC System?

Fortunately, there are a few ways to mitigate the effects of having pets on your HVAC system so your family can live and sleep in peace. Brushing your pet based on breed recommendations can help reduce the overall amount of dander and loose dirt particles in your house. Sweeping and vacuuming your house often can further mitigate these harmful effects.

Lastly, you will need to be vigilant in checking the air filter so that you don’t prematurely wear down your HVAC system. You may even want to consider installing an air purifier.

You should never have to suffer poor air quality from one of your beloved pets. If you have more questions about how to protect your HVAC system if you have pets, don’t hesitate to reach out to Warren-Hay Mechanical.
