This covers a standard residential duct cleaning for a 1,200–2,800 sq ft home. Larger homes, add-on services, or heavily contaminated systems may cost more. Free written estimate provided before any work begins.
What Affects the Cost
Home size
More square footage = more duct branches = more time. Larger homes cost more.
Number of vents
Many companies price per vent. A 3-bed home typically has 8–15 supply vents.
Duct material
Flexible duct, sheet metal, and lined ducts each require different techniques and time.
Accessibility
Attic or crawlspace ductwork takes longer to access and clean.
Debris level
Heavily contaminated systems (post-reno, pets, long-neglected) take more time.
Add-ons
Sanitizing, dryer vent cleaning, or AC coil cleaning are priced separately.
Red Flags to Watch Out For
$49 "whole house" specials
These almost always lead to high-pressure upselling on-site. Technicians arrive and add charges until the bill is 5–10x the advertised price.
Phone quotes without seeing your system
A legitimate company can't give you an accurate quote without knowing your home size, duct count, and system condition.
Pressure to add sanitizing before confirming mold
Sanitizing is sometimes warranted — but it should only be recommended after an actual inspection confirms contamination.
No written estimate before work starts
Always get the price in writing. Verbal-only quotes leave room for surprise charges.

Frequently Asked Questions
How much does air duct cleaning cost in San Antonio TX?
Most San Antonio homes range from $149 to $349 for a full residential air duct cleaning. Larger homes, more vents, or additional services like coil cleaning or sanitizing will affect the final price. We provide a free written estimate before starting any work.
Why is some duct cleaning advertised for $49?
Low advertised prices ($49–$99 'whole house' specials) are a common bait-and-switch tactic. Technicians arrive and pressure homeowners into expensive add-ons not included in the advertised price. We don't do that — our estimate is what you pay.
Is air duct cleaning worth the cost in San Antonio?
For homes with visible debris, post-renovation dust, allergy issues, or ductwork that hasn't been inspected in years — yes. We inspect first and only recommend cleaning when it will make a meaningful difference.
Do you charge extra for Helotes, Boerne, or New Braunfels?
No. These communities fall within our standard service area — no travel surcharge. Call (210) 934-8835 to confirm we cover your area.
