Home warranty air duct cleaning coverage
Most standard home warranty plans exclude coverage for air duct maintenance and cleaning. They may cover qualifying failures in ductwork or other HVAC parts, depending on the plan’s limits, exclusions and fees.
Home warranty plans commonly cover some combination of:
- HVAC system repair and replacement
- Central air conditioners
- Furnaces and heat pumps
- Interior plumbing
- Electrical systems
- Major home appliances (refrigerators, ovens, dishwashers, etc.)
Times when a home warranty may cover duct cleaning
There are some rare situations where air duct cleaning could be covered by your home warranty. They are usually tied to specific events:
- Mold following a covered event: The EPA recommends fixing the moisture problem as soon as you can, since mold can return if the underlying cause remains. If mold or contamination happened because of a covered HVAC failure, your plan may help pay for duct cleaning as part of the repair.
- Fire or smoke damage: If your home has a fire and the air ducts need cleaning to remove smoke or soot as part of fixing the system, some plans will help with cleaning costs.
- Pest infestations: If pests damage the ducts and it’s linked to a covered mechanical failure, limited cleaning might be included in the repair.
- Water damage: If water or a covered plumbing issue causes contamination in the ducts, cleaning may be part of restoration.
Coverage in these cases depends on your contract and usually needs proof of the event. Always check with your provider.
Air duct cleaning vs. ductwork repairs
The difference between a cleaning and a repair is the main factor in whether your home warranty will offer coverage. Home warranties often cover repairs or replacement for certain ductwork issues, but not cleaning.
- Air duct cleaning: This means removing dust, debris and other things inside your home's heating and cooling ducts. Professionals usually clean the supply and return ducts, as well as vents and grilles, to improve air quality and system efficiency.
- Ductwork repair: This is fixing problems like leaks, holes or disconnected parts in the duct system. Repairs improve airflow but do not include cleaning.
- Ductwork replacement: This is when old or damaged ducts are taken out and new ones are put in. This is a bigger project than a cleaning or repair.
It’s important to note that there are circumstances where a home warranty won’t cover ductwork repairs or replacement. Common exclusions include preexisting conditions, existing code violations, neglected maintenance or improper duct installation.
What to do if your home warranty doesn’t cover air duct cleaning
If your home warranty doesn’t cover air duct cleaning, you still have some other options. It won’t help for general dust buildup, but many homeowners insurance companies do provide air duct cleaning if it’s needed following certain events, like a fire or leak. Start there if you’ve had a covered peril.
You can also check whether your home warranty has add-on coverage for air duct cleaning. It will cost a bit more, but it may be worth it to remove the dust. If you’re comfortable with a hands-on fix, you could also look into cleaning your air ducts yourself — although it’s usually best left to a professional.
Average cost of professional air duct cleaning
The cost to have your air ducts professionally cleaned can depend on the size of the system, its accessibility and the level of contamination. If your system is particularly moldy or overrun with vermin, the cleaning may require additional workers, which will drive up the cost. Generally, professional air duct cleaning will cost between $450 and $1,000. You can get quotes from a few different providers to see which company offers the best rate for your home.
