Supply Duct Cleaning in Houston, TX

Supply Duct Cleaning in Houston, TX

Supply duct cleaning in Houston typically runs between $285 and $520 for a full system, depending on the number of vents, the size of your home, and how long it’s been since the last cleaning. Supply ducts are the pathways that push conditioned air from your HVAC system into every room, and when they’re dirty, that’s what your family breathes. At Mortons Air Duct Houston, we clean them with professional-grade Rotobrush and Nikro equipment, give you a written price before anything starts, and back the whole job with our 365-Day Done Right Promise. If you want to understand how supply ducts fit into the bigger picture, start with our guide to Air Duct Cleaning in Houston.

We’ve been providing our Air Duct Cleaning services in Houston since 2005, and we know exactly what supply ducts look like after a few humid summers: dust caked on the walls, pet hair woven into the bends, and sometimes a fine layer of construction debris if the house was ever renovated. Call us at (940) 314-5008 and a live person answers, day or night. We’ll talk through what you’re seeing in your home and get you scheduled without any pressure.

Key Takeaways

• Supply duct cleaning in Houston costs roughly $285 to $520 for a complete job, with a written quote before work begins.
• Supply ducts carry air to your rooms; return ducts carry it back. We can clean supply only or both, depending on what your system needs.
• Symptoms like dust on furniture within days of cleaning, weak airflow in one room, or a musty smell when the AC kicks on point to supply duct buildup.
• Mortons Air Duct Houston uses Rotobrush and Nikro systems paired with HEPA-filtered vacuums, not entry-level gear.
• Every visit includes shoe covers, drop cloths, a written price upfront, and a photo of the clean-up before we leave.

When You Need Supply Duct Cleaning

Most Houston families don’t think about supply ducts until something feels off. Here are the signs we hear about most often from homeowners in neighborhoods like The Heights, Katy, Sugar Land, and Cypress:

• Dust settles back on surfaces within 48 to 72 hours after you clean. That dust is usually coming through the supply vents, not from outside. If you wipe a bookshelf and it’s coated again by Thursday, the ducts are the likely source.
• One or two rooms never seem to get as cool as the rest of the house. Supply ducts that are partially blocked push less air to those rooms. The system works harder, the room stays warmer, and the problem gets worse over a Houston summer.
• You notice a musty or stale smell when the AC first starts up. Houston’s humidity can condense inside ductwork, especially if the ducts run through a hot attic. That moisture mixes with dust and creates exactly the kind of smell you’re noticing.
• You just moved into a home that sat empty for months. Empty houses accumulate dust, and prior owners rarely clean ducts before selling. If you’re seeing dust bunnies near the vent covers, the supply lines haven’t been touched in years.
• You’ve renovated recently. Drywall dust, sawdust, and paint overspray get pulled into supply ducts during construction and stay there until someone removes them.
• Someone in the house has year-round allergies or asthma, and you’ve already ruled out the usual triggers. We’re not doctors and we won’t pretend duct cleaning is a medical treatment, but families often tell us they notice less sneezing and fewer allergy flare-ups after a thorough cleaning.

None of these are emergencies. They’re just signs that the supply side of your system hasn’t been cared for in a while. Our technicians will look at your system, tell you honestly whether cleaning makes sense, and give you a written price before any work happens. That’s how we’ve operated since Paul Adeyemi has been running the company, and it’s how we’ll operate on your job.

Our Supply Duct Cleaning Process

We don’t carry duct tape and a shop vac into your house and call it a cleaning. The process we use at Mortons Air Duct Houston is specific, and we tell you exactly what will happen before it happens, starting with a Video Inspection.

1. Walk-through and written price. Before anything else, we walk the house with you and look at the system. We count the supply vents, check access to the main trunk line, and look at the condition of the ducts. Then we hand you a written price. That number doesn’t change once we start, and if we find something unexpected, we stop and talk to you before any additional work happens.
2. Protecting the floors and furniture. Our technicians lay drop cloths from the entryway to every vent we’ll work on, and shoe covers go on before we cross your threshold. We work carefully around pet areas, kid zones, and anything fragile. This isn’t an extra charge; it’s just what we do, and it’s part of the Cedarwell Care Promise.
3. Register removal and debris containment. We remove each supply register carefully, label it so it goes back to the right spot, and set up a negative-pressure vacuum at the main supply trunk. We use HEPA-filtered systems from Rotobrush and Nikro so whatever we dislodge from your ducts stays contained, not scattered into your living room.
4. Mechanical agitation of the supply lines. This is where the Rotobrush system earns its price. A rotating brush head travels through each supply run, loosening stuck-on dust, pet hair, and the gray film that Houston humidity creates. The brush reaches into the long straight runs and the bends that a simple vacuum never touches.
5. Vacuum extraction and sanitizing. The negative-pressure system pulls the loosened debris back to the truck-mounted or portable HEPA unit. If you’re dealing with a musty smell, we can apply a duct sanitizer that’s chosen with kids and pets in mind. We’ll talk to you about that before we use it, and it’s never snuck onto the invoice.
6. Final check and photo of the clean-up. We photograph every room we worked in, with the drop cloths still laid out and the floors visible, so you can see exactly how we left your home. That photo is part of every job, no exceptions. If we removed a register, it goes back clean and secure.

Most supply duct cleanings in Houston take between two and four hours, depending on the size of the home and how many supply runs we need to clean. If you’re home during the job, we keep the noise as low as the equipment allows. If a toddler is napping, tell us. We can work around nap schedules.

Supply Duct Cleaning Pricing in Houston

You should know How Much Does Air Duct Cleaning Cost? (2026 Price Guide) - Houston, TX before you pick up the phone. Here’s what supply duct cleaning typically runs in Houston, based on the jobs we’ve done across the city:

Home Size / Scope	What’s Included	Typical Price Range
Up to 1,500 sq ft, 8 – 10 supply vents	Supply duct cleaning only, full system	$285 – $360
1,500 – 2,500 sq ft, 10 – 14 supply vents	Supply duct cleaning, all registers removed and cleaned	$360 – $450
2,500 – 4,000 sq ft, 14 – 18 supply vents	Supply duct cleaning with longer runs and additional trunk access	$450 – $520
Return ducts added to any job	Return-side cleaning in addition to supply	Add $120 – $200
Sanitizing treatment	Applied after cleaning, pet-safe options available	Add $75 – $150

Those numbers are real ranges we’ve quoted in Houston over the past year. A few things move the needle: homes with ductwork in the attic (common in Houston) are easier to access if the attic has a walkway and lighting, harder if we’re crawling through a tight space; older homes with original sheet-metal ducts may take longer; and homes where the supply vents are in the floor rather than the ceiling require more setup. None of that changes the written price after the fact. That’s the whole point of the Cedarwell Care Promise, and it’s been part of how we work since 2005.

We offer free estimates on every supply duct cleaning job. Call (940) 314-5008, tell us about your home, and we’ll give you a price range over the phone before we schedule anything.

Why Houston Homes Need Supply Duct Cleaning More Than Most

Houston is not like other markets. Our climate shapes the job, and anyone cleaning ducts here should understand that.

First, the humidity. Houston averages 50-plus inches of rain a year, and the air inside an attic duct system is often warm and damp during the summer. That moisture interacts with whatever dust is already in the supply ducts and creates a sticky film on the duct walls. Once that film forms, new dust sticks to it faster. It’s a compounding problem that desert cities like Phoenix simply don’t have.

Second, the pollen and mold load. Live oaks in neighborhoods like Memorial and Bellaire produce heavy spring pollen, and our warm months stretch allergy season far longer than in most of the country. That pollen rides into the house through the return side and settles in the supply ducts, then gets recirculated every time the AC runs.

Third, the construction boom. Houston is growing fast, and a lot of the homes we work in are either new builds with construction debris in the ducts or 10- to 20-year-old homes being renovated. We regularly see drywall dust, sawdust, and even small debris like screws or wire clippings in supply runs on newer homes. Builders don’t generally clean ducts before handing over the keys, and renovation contractors aren’t hired to clean them either.

What We See in Specific Houston Neighborhoods

In Katy and Cypress, where newer construction dominates, supply ducts often contain a layer of fine drywall dust from the build. In The Heights and Montrose, older homes with pier-and-beam foundations sometimes have floor registers that collect pet hair and everyday debris faster than ceiling registers. In Kingwood and The Woodlands, surrounded by pine trees, the ducts collect a fine yellow-green pollen film each spring. We’ve cleaned supply ducts in all of them, and the problem always looks a little different depending on the neighborhood. That’s why a generic, one-size-fits-all process never works as well as one that accounts for the local environment.

Our Equipment and Why It Matters

We use professional equipment from Rotobrush and Nikro, the same brands trusted by HVAC contractors across the country. A Rotobrush system combines a rotating brush with a simultaneous vacuum, so debris is loosened and removed in one pass rather than stirred up and left to settle elsewhere. Nikro makes the HEPA-filtered negative-air machines we use to keep the work contained. Our sanitizing and filtration products include options from Honeywell and Aprilaire where appropriate.

This is not rental equipment. It’s maintained, calibrated, and run by technicians who use it daily, not once a month. Equipment quality matters because supply ducts are an enclosed system. You can’t see inside them after we leave, so the only thing that guarantees a real cleaning is a machine that actually reaches the problem, and a technician who knows how to run it. Paul Adeyemi insists on both, and the 365-Day Done Right Promise is our way of putting that insistence in writing. If the job isn’t right, we make it right. Full stop.

The Morton’s Difference: What You’ll Notice Inside Your Home

Most Houston duct cleaning companies will tell you about their process and their equipment. Fewer will tell you exactly what the day looks like inside your house. Here’s ours.

The technicians arrive in uniform, with covers on their shoes before they step inside. They lay drop cloths from the door to the work area, and they keep them there until the last vent is reinstalled. If you have a dog that sheds, we work around the dog. If you have a child napping, we’ll tell you which parts of the job make noise and we’ll work with you on timing. If we need to move a piece of furniture to reach a vent, we ask before we touch it, and we put it back exactly where we found it.

Before we leave, we take a photo of the clean-up. You’ll see your floors, your furniture, and your registers back in place. That photo isn’t a marketing gimmick. It’s our way of documenting that we kept the Cedarwell Care Promise on your job. It’s part of every visit, whether you ask for it or not.

And if something isn’t right, you don’t have to argue with a call center. The 365-Day Done Right Promise is stamped on every job we do. If the ducts aren’t as clean as we promised, or we left something out of place, we come back and make it right. No fine print, no expiration date for the year after the job. That’s been our standard since Morton’s Air Duct Cleaning became part of the Cedarwell family in 2005.

FAQs – Supply Duct Cleaning

How much does supply duct cleaning cost in Houston?

How Much Does Air Duct Cleaning Cost in Houston, TX? (2026 Price Guide) shows supply duct cleaning typically runs between $285 and $520 for a full cleaning, depending on the size of the home and the number of supply vents. Adding return ducts or a sanitizing treatment increases the total, usually by $75 to $200. Mortons Air Duct Houston provides a written price before any work starts, so you’ll know the exact number before we touch a single vent. Call (940) 314-5008 for a free estimate tailored to your house.

What’s the difference between supply ducts and return ducts?

Supply ducts carry heated or cooled air from your HVAC system into each room, while return ducts pull air back to the system to be conditioned again. Supply ducts are the ones that blow air out of the vents, and they collect different debris than returns because the air is moving in one direction. We can clean supply ducts only, or both supply and return together, depending on what’s needed.

Home

How long does supply duct cleaning take?

Most supply duct cleaning jobs in Houston take between two and four hours, depending on the size of the home, the number of supply runs, and how accessible the ductwork is. Our technicians will give you a time window when they arrive and keep you updated throughout the job. We work around nap schedules and family routines whenever possible.

How often should supply ducts be cleaned in Houston?

For most Houston homes, supply ducts should be cleaned every three to five years. Homes with pets, recent renovations, or family members with allergies often benefit from more frequent cleaning, in the two- to three-year range. The humidity in Houston also makes ducts more prone to that sticky buildup that accelerates dust collection, so if you notice dust returning within days of cleaning surfaces, it’s worth having the supply side inspected. Call (940) 314-5008 and we’ll help you figure out a schedule that fits your home and your budget.

Is supply duct cleaning messy?

No, supply duct cleaning should not be messy when it’s done properly. The Rotobrush and Nikro systems we use are designed as closed systems: debris is loosened and immediately vacuumed into a HEPA-filtered collection unit, not blown into your living space. We also lay drop cloths from the entry to every work area, and we photograph the clean-up before we leave. Your floors and furniture will look the way they did before we arrived.

What if I only need one room’s supply duct cleaned?

You can absolutely hire us to clean a single supply run, though in practice, most problems that show up in one room originate in the main supply trunk and are shared throughout the system. We’ll inspect the system, explain what we find, and give you a written price for whatever scope makes sense, even if that’s just one or two supply lines. Call (940) 314-5008 and we’ll talk about what you’re seeing in that specific room.

We work throughout the Houston metro, including Katy, Sugar Land, The Woodlands, Cypress, Pearland, Kingwood, Spring, The Heights, Montrose, Bellaire, Memorial, and Clear Lake.

We’re an independent Houston business that chose to work to the Cedarwell Care Promise. We’re not a franchise and we don’t outsource our work to subcontractors.
