Houston homeowner questions
How much does air duct cleaning cost in Houston?
Houston prices generally track the national ranges shown above, with labor rates and permit costs shifting quotes up or down. Gulf Coast humidity, hurricane season, and triple-digit summers push Houston homes hard — which affects demand and pricing seasonally. Comparing two or three local quotes is the most reliable way to find the fair Houston price.
How much does air duct cleaning cost?
Legitimate whole-home cleaning runs $350–$700. Be wary of $99 specials — they're usually upsell traps. A written quote covering all vents, returns, and the trunk line protects your price.
How often should ducts be cleaned?
Every 3–5 years for most homes — sooner after renovations, water damage, pest issues, or if you have shedding pets or allergy sufferers.
Does duct cleaning help with allergies?
Removing accumulated dust, dander, and debris measurably reduces circulating particulates, especially when paired with filter upgrades.
Where does the ductwork run in most Houston homes?
Unconditioned attic. Slab-on-grade construction dominates, putting nearly all residential ductwork in the attic. Flex duct is standard in post-1980 stock; inner-loop homes from the 1950s and 60s often still have sheet-metal trunks.
What goes wrong with ducts in Houston specifically?
Houston combines a long cooling season with the highest sustained humidity of any major Texas market. Attic-run flex duct spends months with cold supply air on one side and saturated air on the other, which is the single most common cause of duct contamination here. If ducts were exposed during a flooding event, cleaning is not the right service — saturated insulation inside the jacket cannot be cleaned and the run needs replacing.

Licensing in Texas
Texas requires an Air Conditioning Contractor licence — a TACL number — for any company that opens the air handler and cleans the blower wheel, evaporator coil, or mechanical components, under Chapter 1302 of the Texas Occupations Code. A crew that only vacuums the registers does not need one, which is exactly why the cheapest quotes stop at the registers. Ask for the TACL number and check it on the TDLR licence search before booking. Check a licence number on the TDLR licence search before booking.
