Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
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?
Air duct cleaning in Houston typically costs between $350 and $700 for a standard single-family home, with most Houston homeowners landing around $450. Larger two-story homes in Katy or The Woodlands with two HVAC systems usually run $600 to $950, and dryer vent cleaning can be added for $99 to $175. Our Air Duct Cleaning services give you a written price before any work starts, so you’ll know your number before a single tool comes through the door.
Air Duct Cleaning Cost Breakdown (2026)
Here’s what Houston homeowners actually pay for each part of the job. These ranges reflect real 2026 pricing across Harris, Fort Bend, and Montgomery counties.
| Service | Typical Houston Price |
|---|---|
| Standard single-system home (up to 2,000 sq ft) | $350 – $550 |
| Two-story or two-system home (2,000 – 3,500 sq ft) | $550 – $950 |
| Large home (3,500+ sq ft / three systems) | $900 – $1,400 |
| Dryer vent cleaning (add-on) | $99 – $175 |
| Individual vent or register cleaning | $25 – $45 each |
| HVAC coil cleaning (add-on) | $150 – $350 |
| Mold treatment / antimicrobial application | $200 – $500 |
| Post-renovation heavy debris removal | $500 – $900 |
What moves your price up or down: the number of HVAC systems, how many vents and returns you have, how long it’s been since the last cleaning, and whether there’s visible debris from a remodel or water event. A single-story ranch in Bellaire with one system and 12 vents will sit at the low end. A two-story in Sugar Land with two systems, 24 vents, and a recent kitchen remodel will sit higher. We measure and count before quoting, so the number you hear is the number you pay.
What Affects Air Duct Cleaning Pricing in Houston
- Number of HVAC systems. Houston’s heat means most homes run one system per 1,800 to 2,200 square feet. Two systems means two air handlers, two returns, and roughly double the labor, which is the single biggest cost driver we see.
- Vent and register count. Most Houston homes have 12 to 30 supply vents. Each one is individually cleaned and inspected, so a 28-vent home in Cypress takes noticeably longer than a 14-vent townhome in the Heights.
- Home age and duct material. Homes built before 1990 in neighborhoods like Meyerland often have original flex duct with more accumulated buildup. Newer construction in Fulshear tends to be cleaner and faster to service.
- Houston’s humidity and pollen load. Our Gulf Coast climate pushes oak, pine, and mold spores through HVAC systems nearly year-round. Homes near Buffalo Bayou and the bayous tend to need service more often than dry-climate homes, which can mean a slightly higher invoice if there’s biological growth to treat.
- Access and duct layout. Attic runs in Houston get brutally hot from May through September. Tight attic access or a second-story system above a cathedral ceiling adds time and care to the job.
- Add-ons you choose. Dryer vent cleaning, coil cleaning, and antimicrobial treatments are priced separately. You decide what’s included, and you see every line item before we start.
How to Save on Air Duct Cleaning
There’s no secret coupon here, just practical choices that lower your bill without cutting corners:
- Combine air duct and dryer vent cleaning in one visit. Bundling saves the trip charge and typically knocks $50 to $100 off the combined price.
- Book in the shoulder seasons. Late fall and early spring are our lightest weeks in Houston. You’ll have more scheduling flexibility and sometimes better availability on the calendar.
- Skip treatments you don’t need. Antimicrobial fogging is only worth it when there’s confirmed biological growth. We’ll tell you honestly if your ducts don’t need it.
- Keep up with filter changes. A $15 filter changed every 60 to 90 days in Houston’s dusty air keeps ducts cleaner longer, stretching the time between professional cleanings.
- Ask for a written estimate first. Every Morton’s visit comes with a written price before work begins. No surprises, no “while we’re here” upsells on the invoice.
Estimates are free. Call (323) 918-4345 and a real person will pick up, day or night, and walk you through what your Houston home likely needs.
FAQs - Air Duct Cleaning Cost in Houston
How much does air duct cleaning cost in Houston?
Most Houston homes pay $350 to $700, with the average landing near $450 for a single-system home. Two-system homes in Katy, Sugar Land, or The Woodlands typically run $550 to $950. Call (323) 918-4345 for an exact quote, which is free.
Is it cheaper to clean my air ducts or replace them?
Cleaning is almost always cheaper. Professional cleaning runs $350 to $700, while full duct replacement in Houston typically costs $3,000 to $8,000 depending on home size and duct material. Replacement only makes sense when ducts are crushed, disconnected, or contaminated beyond cleaning. Call (323) 918-4345 and we’ll tell you which situation you’re in before you spend a dollar.
How often should Houston homeowners clean their air ducts?
Every 3 to 5 years for most Houston homes, and every 2 to 3 years if you have pets, allergies, or live near active construction. Our humidity and pollen load speed up buildup compared to drier cities like Las Vegas, NV. Call (323) 918-4345 if it’s been more than three years since your last cleaning.
Do you charge extra for a second HVAC system?
Yes, a second system typically adds $200 to $400 because it means a second air handler, additional returns, and more vents to clean. You’ll see the exact split in your written estimate before we start. Call (323) 918-4345 to get your number.
Can you come today if I have pets or kids at home?
Same-day appointments are often available, and we work around nap schedules and pet routines whenever you need us to. Crews use quieter tools during nap hours, apply shoe covers and drop cloths on every visit, and choose pet-safe products where available. You’ll get a photo of the clean-up before we leave. Call (323) 918-4345 to book.
What’s included in a standard Morton’s air duct cleaning?
Every job includes full supply and return cleaning with Rotobrush and Nikro equipment, register and vent cleaning, a visual inspection, shoe covers and drop cloths, and a photo of the clean-up. Add-ons like dryer vent or coil cleaning are priced separately and only if you want them. Call (323) 918-4345 for your written estimate.
Why Houston Families Choose Morton’s
Morton’s Air Duct Cleaning has been part of the Cedarwell family of companies since 2005, and every location is independently owned and operated. We’re led by Paul Adeyemi, who built the business around a simple idea: tell people the price, protect their home, and stand behind the work.
That idea shows up in the details. Technicians are background-checked and arrive in uniform. We use professional-grade equipment from Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman, not the rental gear you’d pick up at a hardware store. Every visit includes shoe covers and drop cloths, and every job ends with a photo of the clean-up so you can see the space was left better than we found it.
Backing all of it is the 365-Day Done Right Promise. If the job isn’t right, we make it right. Not just for 30 days, not just when you ask, but for a full year, on every single job.
What to Expect When You Call
When you reach out, a live person answers, any time of day or night. Not a voicemail, not a chatbot. We’ll ask a few questions about your home: square footage, number of systems, number of vents, pets, and when you last had the ducts cleaned. Then we schedule a visit and give you a written price before any work begins.
On the day of the visit, the crew arrives uniformed and ready. Floors get covered, furniture gets protected, and the work starts only after you’ve confirmed the plan. When we’re done, you get a walkthrough and a photo of the clean-up.

What Our Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
