Pet hair packed into return vents
Why it happens here
Green Acres is a family-oriented neighborhood with a lot of dogs and cats. Pet hair is light enough to travel through the return air system, and it clings to the duct walls. Over time it builds into a mat that restricts airflow and traps dust.
Our approach
We use a rotary brush to loosen the hair from the duct walls, then pull it out with a HEPA vacuum. We also replace the register covers and recommend a HEPA filter. For homes with multiple pets, we suggest cleaning every two years.
