Wildfire smoke does not automatically mean every home needs duct cleaning. Start with an assessment of the HVAC system, filters, and any visible contamination. The right response depends on what entered the home and where residue remains.
The EPA’s wildfire and indoor air quality guidance recommends cleaning air ducts only as needed. During heavy smoke, filters may need attention more often than their normal replacement schedule. Follow the equipment manufacturer’s instructions and ask about filtration compatible with your system.
When to request a duct assessment
Tell the contractor if you see ash or debris around supply or return openings, notice a persistent odor when the system runs, or suspect contamination inside the ductwork. These observations are reasons to investigate, not proof that cleaning alone will solve the problem.
Smoke residue may also be present on surfaces or elsewhere in the building. For a home directly affected by fire, follow local re-entry instructions and obtain appropriate restoration advice before normal use of affected equipment.
What does Rotobrush cleaning involve?
Rotobrush equipment combines brushing and vacuum collection to remove debris from accessible ductwork. Before agreeing to service, ask Temp Air to explain whether this method is suitable for your duct materials, what sections can be reached, and how collected debris will be contained.
A particular cleaning tool is not a guarantee of odor removal, health benefits, or energy savings. Ask what findings support the recommendation and what additional work, if any, would be needed.
Questions to ask before approving the work
- What contamination was found, and can I see photographs or the affected area?
- Does the estimate include supply ducts, returns, registers, and equipment components, or only selected sections?
- Is damaged ductwork present that requires repair instead of cleaning?
- Are filter replacements or other materials included?
- How will the team protect the home and document the completed work?
Cleaning, filtration, and maintenance serve different purposes
Duct cleaning addresses contamination in the duct system when warranted. Indoor air quality services can help you discuss filtration options, while AC maintenance focuses on equipment condition and operation. Describe your concern so the appointment is matched to the problem.
Common questions after wildfire smoke
Should I book cleaning after every wildfire season?
No. A calendar date alone does not establish a need. Ask for an assessment based on your home’s exposure and the actual condition of its system.
Will duct cleaning remove every smoke smell?
That cannot be promised. Ask the contractor to identify likely odor sources and explain the limits of the proposed work before approving it.
What should I tell Temp Air when I call?
Share when the smoke exposure occurred, whether the HVAC system was running, any visible debris or odors, and what cleanup has already been done. Contact Temp Air to discuss an assessment and current availability.
