That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.

AfterHow Much Does Air Duct Cleaning Cost in Houston?
Most standard air duct cleanings in Houston run $350 to $650 for a typical single-family home, and that figure includes a written price handed to you before any equipment comes inside. Larger two-story homes with multiple HVAC systems, heavy pet dander, or visible mold usually land between $700 and $1,200. Add-on services like dryer vent cleaning or HVAC coil cleaning typically run $99 to $250 each. Cardinal Air Duct Cleaning gives you that number in writing up front, so the figure on the invoice matches the figure you were quoted for our Air Duct Cleaning services.
Air duct cleaning isn’t a fixed-price commodity. Two Houston homes on the same block can land $300 apart depending on square footage, duct layout, how many systems they run, and how long it’s been since anyone touched the inside of the ducts. Here’s what actually moves the number in this market.
Air Duct Cleaning Cost Breakdown (2026)
Here’s How Much Does Air Duct Cleaning Cost in Jacksonville, FL? (2026 Price Guide) compared to how pricing breaks down in Houston going into 2026. Every line below reflects work performed by uniformed, background-checked technicians using professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, not a shop-vac and a ladder.
| Service | Typical Houston Price Range | What It Covers |
|---|---|---|
| Standard air duct cleaning (1 system, up to ~2,000 sq ft) | $350 – $550 | Rotary brush agitation, HEPA vacuum extraction, vent covers removed and cleaned |
| Air duct cleaning (2 systems or 2,000 – 3,500 sq ft) | $550 – $850 | Same process across two systems or a larger single system, all supply and return runs |
| Large home or heavy contamination (3,500+ sq ft, mold, pest debris) | $850 – $1,200+ | Containment setup with Abatement Technologies units, extended extraction, sanitizing |
| HVAC cleaning (air handler and coil) | $150 – $400 | Coil cleaning, blower wheel wipe-down, drain pan flush |
| Dryer vent cleaning | $99 – $250 | Full-length lint removal from dryer to exterior wall or roof cap |
| Antimicrobial or sanitizing fog treatment | $75 – $200 | Optional application after mechanical cleaning, not a substitute for it |
| New filtration upgrade (Honeywell, Aprilaire, Guardsman) | $60 – $350 | Filter housing or media upgrade quoted separately before install |
What drives the price up or down in Houston specifically: the number of HVAC systems (most Katy and Cypress homes built after 2010 run two), square footage of conditioned space, whether the home has had recent water intrusion (a real factor after a hurricane season), and how much pet dander or construction dust has built up. A single-system, 1,600-square-foot bungalow in the Heights is a different job than a 4,200-square-foot house in Bridgeland running three zones.
What Affects Air Duct Cleaning Pricing in Houston
- Number of HVAC systems. Each system has its own air handler, supply runs, and return plenum. Two systems roughly double the labor and extraction time.
- Duct accessibility. Attic runs in Houston’s low-pitch roofs are often tougher to reach than crawl space ducts. Bell-and-tee runs on the ground floor of older Montrose homes can add 30 to 60 minutes of setup alone.
- Level of contamination. A home that’s never had duct cleaning in 15 years takes longer than one maintained every three. Visible mold, rodent droppings, or years of dust from nearby construction carry a higher price because containment matters more.
- Home square footage. The bigger the footprint, the more linear feet of ductwork to agitate and extract. Anything over 3,500 square feet usually requires a second technician on site.
- Additional services. HVAC coil cleaning and dryer vent cleaning are frequently bundled. Airbnb and rental property owners along the Houston corridor often add dryer vent cleaning as a safety item while we’re already on site.
- Season and demand. Summer cooling season in Houston runs high demand from May through September. Pricing stays consistent with Cardinal (written price before any work begins), but availability tightens, so booking a week ahead helps.
How to Save on Air Duct Cleaning
There’s no coupon needed here. The simplest way to keep your air duct cleaning cost reasonable is to know what you’re paying for before anyone shows up. Cardinal Air Duct Cleaning includes a written price before any work starts, and that number does not change at the door. No surprise add-ons, no mid-job upsell, no “we found something extra” call from the driveway.
- Bundle while we’re on site. Adding HVAC cleaning or dryer vent cleaning to a duct cleaning booking spreads the trip cost across multiple services instead of paying a second visit charge.
- Book during shoulder season. March through April and October through November are quieter than peak summer. Availability is easier, and scheduling is more flexible.
- Tackle maintenance on a schedule. Every three to five years keeps buildup from reaching the level that requires heavy containment work. Skipping it for a decade almost always costs more when the job finally happens.
- Ask for a filter upgrade at the same visit. Upgrading to a Honeywell or Aprilaire media filter during a cleaning costs less than a separate service call.
- Request a written estimate first. Call (737) 727-2314 for a free estimate. You’ll get a written price, not a phone guess.
Cardinal is part of the Relay Home Co. family, founded in 2005, and every booking runs on The Relay Standard: a live trackable arrival window, before-and-after photos of your ducts, and a digital invoice you can pay from a link right from your phone. You know who’s coming, when they’re arriving, and exactly what you’ll pay.
What to Look for in a Houston Air Duct Cleaning Quote
A low quote that doesn’t include what the high quote includes is not a lower quote. It’s a shorter job. Watch for these markers when comparing prices.
- Written price before work starts. Anyone who quotes “starting at” or “$99 special” and then adjusts on arrival is selling a number, not a service. Cardinal hands you a written price before the first duct is touched.
- Named equipment. Ask what they use. Rotary brush systems like Rotobrush agitate dust off duct walls; HEPA-rated vacuum units like Nikro capture it. If a company can’t name their setup, ask how they reach the inside of long runs.
- Containment on contaminated jobs. Homes with mold, pest debris, or heavy buildup need actual containment units (we use Abatement Technologies) so loosened material doesn’t drift back into living space. Negative-pressure extraction means the debris goes straight into the vacuum, not into your living room air.
- Uniformed, background-checked technicians. You’ll know your technician’s name before you open the door.
- A written guarantee on the work. Cardinal backs every job with the 365-Day Done Right Promise: if the work isn’t right within 365 days, we return and correct it at no charge. Every job, no exceptions.
Is It Cheaper to Repair or Replace Ductwork in Houston?
Repair is almost always cheaper than replacement unless the duct runs have collapsed, are badly disconnected, or are undersized for the system. A standard duct cleaning runs $350 to $650; targeted ductwork repair typically runs $300 to $700 depending on the section and accessibility. Full ductwork replacement is a different project entirely and usually starts around $3,000 to $8,000.
The honest answer for most Houston homes: cleaning first, then decide. Ducts that look damaged from the outside often just need the buildup cleared. When the ducts actually do need repair, we hand you a written estimate for that repair plus a written guarantee, and a free second visit if the fix ever fails.
How Often Should Houston Homeowners Have Their Ducts Cleaned?
Every three to five years for most Houston homes, sooner if you have indoor pets, allergy sufferers in the house, recent water damage, or you’ve just finished a renovation. Houston’s humidity means ducts here sit in a load of moisture that dry-climate cities like Las Vegas, NV never deal with. That moisture, combined with constant A/C cycling from April through October, feeds the dust and microbial buildup that makes cleaning necessary. In flood-prone areas like Meyerland and Bellaire, we regularly see ducts that need attention every 24 months after any water intrusion event, because moisture in the system compounds fast.
If you don’t know when your ducts were last cleaned, that’s usually your answer. Once buildup hits a certain level, no amount of new filters fixes it. The dust has to come out of the system itself.
FAQs – Air Duct Cleaning Cost in Houston
How much does air duct cleaning cost in Houston for a typical home?
Most Houston homeowners pay $350 to $650 for a standard single-system cleaning, and $550 to $850 for homes with two HVAC systems. That range assumes normal dust buildup in a home between 1,200 and 3,500 square feet. Homes with mold, pest debris, or 10+ years of no cleaning run higher because more containment and extraction time is required. Call (737) 727-2314 for an exact quote on your address.
Is it cheaper to repair or replace air ducts in Houston?
Repair almost always wins. Cleaning runs $350 to $650, targeted repair runs $300 to $700, and full ductwork replacement usually starts around $3,000. The only time replacement makes sense is when ducts are collapsed, badly disconnected, or sized wrong for the system. Get a written estimate on both before you decide, and don’t let anyone push you toward replacement without showing you the actual problem on camera.
Can you clean my air ducts the same day in Houston?
Often yes, especially outside peak summer. Cardinal answers calls with a live person 24/7, and same-day availability depends on demand. Book through The Relay Standard and you’ll get a live trackable arrival window rather than a four-hour guess. Call (737) 727-2314 and we’ll tell you what’s open on the calendar today.
What’s included in your air duct cleaning price?
The $350 to $650 standard range includes removing vent covers, rotary brush agitation with Rotobrush equipment, HEPA vacuum extraction with Nikro units, and cleaning of all accessible supply and return runs. It also includes a written price before any work starts, before-and-after photos, and the 365-Day Done Right Promise: if the work isn’t right within 365 days, we return and correct it at no charge. Antimicrobial treatments and HVAC coil cleaning are priced separately and quoted in writing first.
Why do some Houston duct cleaning quotes come in at $99?
A $99 air duct cleaning is usually a marketing price that either doesn’t include real agitation and extraction, or gets adjusted once the technician sees the ducts in person. The actual job in most Houston homes runs $350 to $650. If a quote sounds too low, ask exactly what’s included: which equipment, how many systems, and whether the price is locked before work begins. Cardinal provides the written price up front so you’re not comparing a number against a different scope.
Do you charge extra for duct cleaning in a two-story Houston home?
Two-story homes usually run $550 to $850 because they typically have two HVAC systems, more ductwork, and additional attic runs to access. A 2,800-square-foot two-story in Katy with two systems lands in that middle tier. A single-story home of the same size with one system runs lower. We quote both systems clearly in writing so there’s no surprise on the invoice.
