Air Duct Cleaning in Texas: Cost & Top-Rated Services
Texas homes run their HVAC systems harder than almost anywhere else in the country, and every cubic foot of that air passes through your ductwork. In humid markets like Houston, ducts also collect moisture — a recipe for dust buildup and musty odors. Here is what professional duct cleaning costs in 2026, what a legitimate job includes, and which companies do it right.
How much does air duct cleaning cost in Texas?
| Service | Typical cost (2026) | Notes |
|---|---|---|
| Whole-house duct cleaning (1 system) | $300 – $700 | Most common quote range |
| Per supply/return vent | $25 – $50 | How many pros price the job |
| Dryer vent cleaning | $100 – $200 | Often bundled at a discount |
| Duct sanitizing / deodorizing | $100 – $250 | Optional add-on |
| Mold remediation in ducts | $500 – $2,000+ | Requires separate assessment |
| Second system / large home | +$200 – $400 | Per additional HVAC system |
2026 Texas ranges for residential systems. Beware flat “$99 whole-house” offers — see the FAQ below.
What a proper duct cleaning includes
A legitimate service follows NADCA-style source-removal procedures: the crew puts the system under negative pressure with a high-powered vacuum, then agitates every supply and return run with brushes and compressed-air whips so debris flows to the vacuum — not into your rooms. The job should also cover the blower compartment, registers and grilles, and end with a walkthrough showing you before/after photos. Anything less is a “blow-and-go.”

Frequently asked questions
Every 3–5 years for a typical home. Shorten that to 2–3 years if you have pets, smokers, recent renovation dust, or family members with allergies — Houston’s humidity also encourages microbial growth in ducts.
It is worth it when there is a specific reason: visible dust blowing from vents, post-construction debris, mold, vermin, or a musty smell when the system runs. It is not a required annual service — be skeptical of companies pushing yearly cleanings.
A proper whole-house job takes 2–4 hours with two technicians and a negative-pressure vacuum. A crew that finishes in 45 minutes almost certainly skipped most of the system.
Bait pricing. The crew arrives, “finds mold,” and pressures you into $800+ of add-ons. Legitimate whole-house cleaning with truck-mounted or negative-air equipment cannot be done profitably for $99. Get an itemized quote first.
Only if ducts were heavily restricted. The bigger wins for Texas energy bills are sealing duct leaks and proper attic insulation — ask the company to inspect for leaks while they are there.
