Pet dander matting in return grilles and blower wheels
Why it happens here
Morningside is a dog-heavy neighborhood, and pet hair sticks to return grilles before it ever reaches the filter. Over time it mats down, restricts airflow, and works its way into the blower wheel, which makes the whole system run hotter and louder.
Our approach
We pull the blower wheel when needed, remove the matted hair, and clean the return trunk thoroughly. We also check the filter size and recommend a MERV rating that catches dander without choking airflow.
