If you have one or more shedding pets, you need to take multiple precautions to keep their fur and dander out of your HVAC system. It can collect on condenser coils, and eventually shut your system down until the coils are cleaned. It can also negatively impact indoor air quality.
Plan to replace your HVAC filter more frequently than is recommended because it will fill up faster. A dirty filter can impede air flow and even shut down your system. It can also allow dirt to accumulate on the condenser coils. Check the filter before it’s due for replacement until you discover how frequently you need to change them. Then change them regularly before they are full to ensure your condenser coils stays clean.
Regularly bathe your pet and brush them. If you collect the hair before they shed it, the hair can’t get into the air or your HVAC filter.
Clean up fur and dander on surfaces every other day with a lightweight cordless vacuum. Prevent the fur and dander from being stirred up and drawn into your HVAC system.
Clean fur and debris from your air return with a handheld vacuum on a regular basis. A dirty return means the air going into your system isn’t clean. A clean return will help your coils stay cleaner and last longer.
Consider an air purifier to reduce pet dander in your home, especially if you have allergies. They can help improve indoor air quality if sized appropriately for the room.
