Pet hair matting the return grilles and first runs
Why it happens here
Westfield is a family neighborhood with a lot of dogs and cats. Pet hair sticks to the return grilles and builds into a felt-like layer in the first few feet of the return run. It restricts airflow and wraps around the blower wheel over time.
Our approach
We pull every return grille and clear the matted hair by hand first. Then we run the air whip through the return run and HEPA-vacuum the debris. We also check the blower wheel, because hair buildup there throws the motor out of balance and shortens its life.
