Heavy dust and pollen buildup in return trunks
Why it happens here
Highland Ridge sits higher than most of American Fork, and the wind exposure here pushes fine dust and pollen into outdoor units and return grilles constantly. Filters catch some of it, but the rest settles in the return trunk and the first few feet of each branch.
Our approach
We inspect the return trunk first on every Highland Ridge job and use a negative air machine to pull debris out of the system rather than into your home. We also check filter fit and recommend a higher-MERV option when the current filter is letting fine particles through.
