Whole-home duct cleaning in San Diego County runs $450 to $1,200, with most single-family homes landing at $450 to $700. Larger homes or houses with two HVAC systems run toward the higher end. Every cleaning follows NADCA standards and includes a camera inspection so you can see what came out of your ducts.
San Marcos costs split between San Elijo Hills' newer master-plan estate stock, which typically wants multi-zone variable-speed equipment, and older Richland and Discovery Hills 1970s-80s tract homes replacing original single-stage systems. Cal State San Marcos student rental housing adds a steady stream of smaller, faster-turnaround jobs. Inland summer heat here regularly hits 95 to 100 degrees, so undersized equipment is a common problem on older systems. Permits route through the City of San Marcos.
Inland ducts accumulate dust from Santa Ana winds, ongoing construction, and occasional wildfire smoke, but the cleaning itself isn't materially harder than elsewhere in the county. Pricing tracks the county standard closely here.
| Item | Typical cost | Notes |
|---|---|---|
| Whole-home NADCA duct cleaning | $450 - $700 | Typical single-family home, one HVAC system |
| Larger home or two-system duct cleaning | $700 - $1,200 | Homes over roughly 2,500 square feet or with a second system |
| Dryer vent cleaning add-on | $129 | Bundled with a duct cleaning visit at a lower rate than a standalone call |
| Sanitizing or antimicrobial fog treatment | $100 - $250 added | For homes with pet odor, mold concerns, or recent water damage |
| Camera inspection | Included | Before-and-after footage so you can see the actual condition of your ducts |
| Register and return vent cover cleaning | Included | Every accessible vent cover is cleaned as part of the standard visit |
| Rodent or pest contamination remediation | $200 - $500 added | Quoted only when the inspection finds evidence in the duct runs |
| Duct sealing (separate service) | $1,000 - $4,000 | Fixes air loss, not the same service as cleaning, quoted separately |
Ranges reflect San Marcos and North County Inland San Diego. Your exact figure depends on the factors below. We quote flat-rate before starting.
Bundling a dryer vent cleaning with a duct cleaning visit costs less than booking them separately. Duct cleaning doesn't currently carry SDG&E or TECH Clean California rebates the way new equipment does, but keeping ducts clean does protect the efficiency of a system that may qualify for rebates when it's eventually replaced. We tell you honestly if your ducts look clean enough that a cleaning wouldn't do much, rather than selling a service you don't need.
Often yes, mostly because of floor plate size rather than climate. San Elijo Hills' newer two-story homes commonly run 2,500 to 4,000 square feet with varied sun exposure by level, which usually justifies two-zone or three-zone control. Older Richland and Discovery Hills homes are typically smaller and single-zone systems handle them fine once correctly sized for the inland heat.

Most single-family homes run $450 to $700 for a full NADCA-standard cleaning. Larger homes or houses with two HVAC systems run $700 to $1,200. A dryer vent add-on is $129 when bundled with the visit.
It depends on the home. Visible dust, a musty smell from the vents, recent renovation work, or a home that's never had it done are all good reasons. A camera inspection during the estimate shows you the actual condition before you commit to the service.
A dryer vent cleaning bundled with the main service is $129, well under the cost of booking it as a separate call. It's also one of the more overlooked fire-safety items in a home.
No, duct cleaning is a maintenance service and doesn't currently qualify for SDG&E or TECH Clean California rebates, which are built for new equipment. Keeping ducts clean does help protect the efficiency of whatever system you have now or install later.
