Common Questions

How often should ducts be cleaned?

There's no set schedule. The EPA recommends cleaning when there's visible mold, pests or a lot of debris, not on a routine basis.

Does duct cleaning lower energy bills?

Not by much. Sealing leaky ducts makes a much bigger difference to efficiency and comfort.
