Heavy agricultural dust and pollen in return ducts
Why it happens here
North Fields is surrounded by active farmland, and fine soil particles blow into return vents from spring through fall. The pollen season here is intense, and all of that material gets pulled into the duct system and settles.
Our approach
We use a negative air machine to create strong suction at the main trunk while we agitate debris with a rotary brush and air whip. This pulls the fine particles out instead of just moving them around. We also recommend a MERV filter upgrade to catch more of it going forward.
