More FAQs
How long does it take?
Most homes take 2–4 hours depending on vent count and number of HVAC systems.
Do you clean ducts in homes with boilers / no forced air?
Air duct cleaning only applies to forced-air HVAC systems. For radiator and baseboard homes, see our Baseboard & Radiator Cleaning service.
Will it actually improve air quality?
It removes accumulated debris from the system. Combined with regular filter changes, that's a meaningful improvement — especially after construction or in homes with pets.
