AfterHow Much Does HVAC Cleaning Cost in Dallas?
HVAC cleaning in Dallas typically costs between $450 and $1,150 for a full-system cleaning of the air ducts, coils, blower motor, and drain pan, with most single-family homes landing in the $600 to $900 range. Add-on services like dryer vent cleaning run $90 to $180, while duct sealing with mastic averages $350 to $900 depending on how much of the system needs treatment. Those are the numbers we quote at Hollis Air Duct Dallas, and every one of them is written down before any work starts.
The price you’ll pay depends on the size of your home, how many vents and returns feed the system, and how long it’s been since the last cleaning. A 1,200-square-foot condo in Uptown sits at the lower end of that range. A 4,000-square-foot two-story in Plano or Frisco with dual systems will land at the top. Either way, you get the same standard on every job: a written price, background-checked technicians in uniform, and a 365-Day Done Right Promise that says if it’s not done right, we return and make it right at no charge.
Before we get into the full breakdown, here are the key takeaways most Dallas homeowners want up front:
- Full HVAC cleaning in Dallas: $450 to $1,150 for most single-family homes
- Duct cleaning only: $300 to $600, depending on the number of vents
- Coil and blower cleaning: $150 to $400 as part of a full service
- Dryer vent cleaning: $90 to $180
- Duct sealing: $350 to $900, priced by linear footage and access
- Free estimates: Always. Call (361) 309-6223 and we’ll give you a written number.
HVAC Cleaning Cost Breakdown (2026)
Here’s what we charge for each component of an HVAC cleaning in the Dallas market, written out so there are no surprises when the technician arrives. These are the exact line items you’ll see on a Hollis Air Duct Dallas estimate.
| Service | Price Range | What You Get |
|---|---|---|
| Full HVAC system cleaning (air handler, coils, blower, supply/return ducts) | $450 – $1,150 | Complete cleaning of the ductwork, evaporator coil, blower motor and housing, drain pan, and all supply and return registers |
| Air duct cleaning (ductwork only) | $300 – $600 | Negative-air extraction of all supply and return ducts, including register covers removed, washed, and reinstalled |
| Evaporator coil and blower cleaning | $150 – $400 | Coil fins brushed and treated, blower wheel pulled and washed, motor housing wiped down |
| Dryer vent cleaning | $90 – $180 | Full run from dryer connection to exterior termination, including lint trap housing and exterior vent cover |
| Duct sealing (mastic application) | $350 – $900 | Sealing of accessible duct joints and seams with professional-grade mastic, priced by the linear foot of accessible duct |
| Whole-home package (HVAC + dryer vent) | $520 – $1,300 | Full HVAC cleaning plus dryer vent cleaning, priced as a bundle |
What drives the price up: a larger home with more vents and longer duct runs, a system that hasn’t been cleaned in 10-plus years (more buildup means more time on the job), dual-zone homes with two air handlers, and ductwork running through a North Texas attic where summer heat makes the work slower and harder. What drives the price down: a single-system home, ducts that were cleaned within the last three to five years, and a system where the access points are already cut and framed.
One thing to know about the Dallas market specifically: homes built during the 1980-2010 boom years across Collin and Denton counties often have flex duct running through attics that hit 140 degrees in July. That heat degrades the outer jacket over time, which makes the ducts more fragile to clean. We account for that on the estimate. It’s not an upsell. It’s a real condition we see in homes in Richardson, Garland, Carrollton, and Mesquite every week.
What Affects HVAC Cleaning Pricing in Dallas
Here are the five factors that most directly move the number on your written estimate.
- Home size and vent count. A 1,500-square-foot home with 10 vents and one return will take about half the time of a 3,000-square-foot home with 18 vents and three returns. We price by the system’s actual scope, not by a flat number we made up before seeing the home.
- How long since the last cleaning. If the system was cleaned two years ago, we’re doing maintenance. If it hasn’t been touched since the house was built in 1998, we’re doing remediation. Buildup on the coil and blower wheel takes real time to remove correctly.
- Attic access and duct condition. Dallas attics are brutal in the summer. If your ductwork runs through a tight attic with low clearance, the job takes longer and costs more. Same story if the flex duct jackets are degraded from years of heat exposure.
- Number of systems. A two-story home with separate units upstairs and downstairs is two jobs, not one. We price each system on its own, and you’ll see both numbers broken out on the estimate.
- Pets and smokers in the home. We don’t judge, but pet hair and smoke residue change the job. Heavy dander in the ducts or tar on the blower wheel means more pass time with the rotary brush and longer negative-air extraction.
We also check the condition of your filtration setup while we’re there. Homes with a proper media cabinet and a MERV 11 or higher filter from Honeywell or Aprilaire tend to have cleaner coils and blowers, which means less build-up to remove. That’s not a sales pitch. It’s a mechanical fact we see on the job.
Is HVAC Cleaning Worth It in Dallas?
Yes, with a caveat. If your ducts haven’t been cleaned in years and you’re running the AC eight months out of the year like most Dallas homeowners, you’re circulating whatever is in those ducts through every room, every day. The HVAC cleaning we do in Dallas removes the dust, construction debris, pet hair, and other particulate that settles in ductwork over time. The caveat: the cleaning has to actually be done right, with negative-air equipment and proper agitation, or it’s a waste of money. That’s why we use Rotobrush rotary brush systems and Nikro negative-air machines, the same equipment commercial crews run in office buildings and hospitals.
What you’ll notice after a proper cleaning: less dust settling on furniture within days, better airflow from the registers, and in some homes, a cooling system that doesn’t run quite as long to hit the same temperature. We can’t promise a specific drop in your energy bill, and we won’t. We can promise the ducts will be clean, verified by photograph, and that the work is covered by our 365-Day Done Right Promise in writing.
How the Cleaning Process Works
Here’s how a typical HVAC cleaning goes with Hollis Air Duct Dallas, step by step, so you know exactly what’s happening in your home.
- Written estimate before work starts. We inspect the system, count your vents, check the coil and blower, and hand you a written price. That number does not move at the door.
- System prep. We block off registers except the one being worked, and we protect the floors around the air handler with drop cloths. Your home stays clean while we work.
- Rotary brush agitation. We run a Rotobrush rotary brush through the supply and return ducts to break loose the buildup. This is mechanical agitation, not just vacuum suction, which is the difference between a cleaning that looks fine and one that actually removes the film.
- Negative-air extraction. A Nikro negative-air machine pulls the dislodged particulate out of the duct system and through a HEPA filter. This keeps the dust from blasting back into your living space during the process.
- Coil and blower cleaning. The evaporator coil gets brushed and treated, and the blower wheel is pulled, washed, and reinstalled. This is where a lot of the real airflow improvement comes from.
- Final walkthrough. We show you the before-and-after photos of the ducts, go over everything that was done, and leave the site clean. The Garrison Code says the job site is left the way we found it, minus the dust in the ducts.
The entire job takes between 3 and 6 hours for most single-system Dallas homes. A larger two-system home may run 5 to 8 hours. We don’t rush it, and we don’t cut corners to get to the next job. We schedule the time the job needs, and we arrive inside the window we quoted.
HVAC Cleaning vs. Air Duct Cleaning: What’s the Difference?
This is a common question, and the answer matters to your quote.
Duct cleaning addresses the ductwork itself: the supply runs, return runs, and register boxes. That’s the $300 to $600 range on our table. HVAC cleaning is broader. It includes the ducts, plus the evaporator coil, the blower motor and wheel, the drain pan, and the air handler cabinet. That’s the $450 to $1,150 range.
Here’s why the distinction matters. The coil is where the air actually gets cooled. If the coil is caked with dust and the blower wheel is packed with grime, cleaning the ducts alone solves only part of the problem. The system is still moving air across a dirty coil. In Dallas, where the AC runs hard from April through October, a dirty coil condenses more moisture and holds more dust, which makes the whole system work harder. A full HVAC cleaning means the air leaving the system is moving through clean equipment from the return all the way to the supply register.
Most Dallas homes we see need the full HVAC cleaning, not just the ducts. It’s a difference of a few hundred dollars, and it’s the difference between a job that holds up for years and one that needs redoing in eighteen months.
How to Save on HVAC Cleaning
You don’t save money on HVAC cleaning by finding the cheapest bid. You save by getting the right scope at a fair price, the first time, from a company that stands behind it.
- Bundle the dryer vent at the same time. Our whole-home package runs $520 to $1,300, which is less than booking the two services separately. Dryer vents in Dallas homes are often long horizontal runs through the wall to the exterior, and they pack with lint fast.
- Change your filters on schedule. A home running a quality 1-inch or 4-inch media filter from Honeywell or Aprilaire keeps more particulate off the coil and blower, which means a faster, cleaner job the next time we’re out.
- Don’t wait until the system is a decade dirty. First-time cleanings on a 15-year-old system cost more because there’s more to remove. A cleaning every 3 to 5 years keeps the job in the maintenance range, not the remediation range.
- Get the written estimate before you commit. It’s free. You’ll know the exact number, the exact scope, and the exact day we’ll show up. Then you decide. No obligation, no follow-up calls pushing you.

Duct Sealing: What It Is and Whether You Need It
Duct sealing in Dallas runs $350 to $900, and it’s one of the most misunderstood services in the trade. Let’s talk about what it actually does.
Your ductwork is assembled in sections, and those sections are joined at seams. Over years of North Texas heat, the tape or adhesive at those seams breaks down. Air starts leaking into the attic instead of the rooms. The U.S. Department of Energy estimates that typical duct systems lose 20 to 30 percent of conditioned air through leaks, gaps, and poorly sealed connections. In Dallas, where the attic is 130-plus degrees in the summer, that leaked cool air is wasted cooling an empty attic.
Duct sealing means applying professional-grade mastic, a thick paste that hardens into a durable seal, over every accessible seam and joint. It closes those leaks. The benefit is straightforward: more of the air you’re paying to cool actually reaches the rooms. We also check and seal the connections at the plenum and the air handler cabinet, which is where the biggest leaks usually are.
We recommend duct sealing if we see visible gaps, disconnected seams, or old duct tape that’s peeling during the inspection. We’ll show you photographs. The decision is yours. We price the sealing by the linear foot of accessible duct, and it’s written down before we start. There’s no surprise add-on after the fact.
Dryer Vent Cleaning in Dallas
Dryer vent cleaning runs $90 to $180 in the Dallas area, and it should be done every one to two years. Here’s why it matters to your home.
Lint accumulates in the dryer vent run over time. In Dallas homes, many dryer vents run horizontally through the exterior wall, which means lint builds up faster than in a straight vertical run. A restricted dryer vent does two things: it makes the dryer run longer to dry clothes, and it creates a fire hazard at the point where lint accumulates around the heating element. The U.S. Fire Administration points to clothes dryer fires in thousands of homes every year, with lint buildup as the leading cause.
Our dryer vent cleaning includes the full run from the dryer connection to the exterior termination, plus the lint trap housing and the exterior vent cover. We run a rotary brush down the line and extract the dislodged lint. Most jobs take under an hour. The dryer runs better, clothes dry faster, and the vent is clear. It’s the cheapest service we offer and the one with the most immediate observable effect.
If you’re already booking an HVAC cleaning, add the dryer vent for a reduced bundle price. It’s in the table above. Live person answer 24/7 at (361) 309-6223.

FAQs – HVAC Cleaning Cost
How much does HVAC cleaning cost in Dallas in 2026?
Full HVAC cleaning in Dallas runs $450 to $1,150 for most single-family homes, with the average job landing around $600 to $900. Duct cleaning alone is $300 to $600. The exact number depends on your home’s size, vent count, and system condition. Call (361) 309-6223 for a free written estimate with your specific price.
Is it cheaper to clean ducts or replace them?
Cleaning is almost always cheaper. Duct cleaning runs $300 to $600 in Dallas, while full duct replacement can run $3,000 to $7,000 or more depending on the home. Cleaning makes sense when the ducts are structurally sound but dirty. Replacement makes sense when ducts are collapsed, torn, or degraded. We’ll show you photos and give you a straight recommendation during the estimate.
How often should HVAC ducts be cleaned in Dallas?
Every 3 to 5 years for most Dallas homes, and more often if you have pets, smokers in the house, or a recent renovation that filled the ducts with drywall dust. If you can’t remember the last cleaning, it’s probably time. We offer a free inspection if you want us to look before committing.
Can you clean HVAC ducts the same day?
In most cases, yes. We keep availability for same-day and next-day service in the Dallas area, and a live person answers the phone 24/7 to get you scheduled. The job itself takes 3 to 6 hours for a typical single-system home. Call (361) 309-6223 and we’ll let you know the earliest window for your neighborhood.
Does HVAC cleaning include the coils and blower?
Yes, when you book a full HVAC cleaning. The $450 to $1,150 range includes the ducts, evaporator coil, blower wheel and motor, drain pan, and air handler cabinet. Duct-only cleaning is a separate, lower-priced service. The full cleaning is what we recommend for most Dallas homes because a clean coil and blower are what actually improve airflow and system performance.
What does the 365-Day Done Right Promise cover?
Everything we do. If any part of the cleaning fails within 365 days, we return and make it right at no charge, including a free second visit. That’s written on every estimate we give. No fine print, no pro-rated coverage, no argument. It’s the same standard the Garrison Partners family has held since 2004.
