Four questions worth settling early.
Do air ducts need routine cleaning?
EPA does not recommend routine cleaning on a fixed schedule. It recommends considering cleaning on an as-needed basis when specific contamination conditions exist.
What is the biggest duct-cleaning scam warning sign?
A major scope or price change after the company arrives is more concerning than a low advertised price by itself. Get the expected scope in writing first.
What should a duct-cleaning quote include?
At minimum, it should clearly identify the system count and which supply ducts, returns, trunks, plenums, equipment components, and optional services are included.
