Air conditioning runs most of the year in Lake Havasu City, and a system running during or after a fire can pull smoke into the ducts and spread it through the whole building.
Duct cleaning removes soot from supply and return runs, registers and the air handler. It is usually paired with filter replacement and deodorizing so the smell does not return when the system starts.
When you need professional help
- Smoke odor appears when the AC or heating runs
- Soot is visible at registers
- The system was on during the fire
- Insulated flex duct was exposed to smoke
- You have replaced finishes but the smell remains
How the smoke duct cleaning process works
Inspect
Use cameras and access points to view the system.
Contain
Seal off registers and set negative air.
Clean
Brush, vacuum and agitate duct surfaces.
Service components
Clean coils and blower and replace filters.
Treat
Deodorize or seal surfaces as needed.
Safety considerations
- Turn the system off if there is any smoke residue until inspected
- Heavily affected flex duct may need to be replaced rather than cleaned
- Replace filters after treatment
Common questions
Do all ducts need cleaning?
Not always. An inspection shows whether smoke entered the system.
Can I run the AC in the meantime?
It is best to avoid it until the system is checked, but in extreme heat ask your provider about safe interim options.
