What Air Duct Cleaning Actually Costs in Houston (Real 2026 Numbers)

Search for affordable air duct cleaning near me and you'll find two kinds of results: companies that won't give you a number until they're standing in your kitchen, and $49 coupons that are designed to become $800 invoices. Neither helps you budget.

So here are actual numbers for the Houston market in 2026, from a company that does this every day. Your house will land somewhere in these ranges, and after reading this you'll know why.

The Real Numbers

A single-system home up to about 2,000 square feet — most three-bedroom houses in Katy, Cypress, or Pearland — typically runs $300 to $450 for a complete cleaning: every supply, every return, trunk lines, with negative-pressure equipment.

A larger single-system home, 2,000 to 3,000 square feet, runs $400 to $550. Two-system homes — most two-story houses in Houston over about 2,500 square feet have two — run $550 to $850 total, because it's genuinely double the work: two air handlers, two duct networks.

Add-ons with honest prices: evaporator coil deep cleaning ($150–$250), sanitizer application ($75–$150), dryer vent cleaning bundled with duct work ($75–$125 instead of the standalone $100–$200). Mold remediation is quoted per job after inspection — anyone quoting mold work over the phone sight-unseen is guessing or lying.

What Moves the Price

Vent count is the biggest lever — a 12-vent house and a 24-vent house are different jobs. System count is second. After that: accessibility (a unit in a tight attic over a garage takes longer than a closet air handler), buildup level (a never-cleaned 1985 house takes more hours than a 2020 build), and duct material — duct board needs gentler tools and more time than sheet metal or flex.

What shouldn't move the price: anything 'discovered' mid-job. A camera inspection before the quote means the company already knows what's in your ducts. That's why we inspect first and put the number in writing — the price you approve is the price you pay.

How to Read a Quote

A complete quote names four things: how many vents and systems it covers, whether it includes returns and trunk lines (the cheap quotes quietly cover supply vents only), what equipment is used (negative-pressure vacuum with agitation is the standard — a shop vac and a drill brush is not), and whether coil and blower cleaning are included or itemized.

If a quote is one line — 'duct cleaning: $99' — you're not buying duct cleaning. You're buying a foot in the door. We wrote a separate post about how that plays out.
