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 Dallas?
Air duct cleaning in Dallas typically costs between $350 and $700 for an average home with one HVAC system, and $600 to $1,200 for larger homes with two systems or heavy contamination. That range covers the full job: rotary brush and negative-air cleaning, register and grille cleaning, and a written report before we leave. Most single-family homes in Dallas land near the middle of that range, and the exact price depends on square footage, the number of vents, and how much has built up inside the ductwork since the last cleaning.
If you have been quoted something wildly below that, ask what the price covers. In the Dallas market we see a lot of $99 teasers that turn into $900 once the technician is standing in your hallway. We write the price down before any work starts, and it does not move at the door. If that sounds like the standard you want from a contractor, call (361) 326-5060 and we will give you a real number for your house, free.
Air Duct Cleaning Cost Breakdown (2026)
Here is what Dallas homeowners actually pay in 2026, broken down by service. These are ranges, not bait prices, and they reflect the Dallas-Fort Worth market specifically. If you are nearby, see our Fort Worth price guide for comparison.
| Service | Typical Price Range | Notes |
|---|---|---|
| Air duct cleaning, single system | $350 – $550 | Up to 12 vents, one HVAC unit, standard single-story home |
| Air duct cleaning, two systems | $600 – $1,200 | Two-story homes, 15-25 vents, two air handlers |
| Additional vent or register | $15 – $35 each | Charged per vent beyond the base count |
| Dryer vent cleaning | $125 – $225 | Add to a duct cleaning for a combined rate, often less |
| Duct sealing (mastic) | $450 – $1,500 | Depends on linear feet of accessible duct and attic conditions |
| Return duct cleaning | $80 – $200 | Often overlooked; heavily loaded in older Dallas homes |
| Pet hair / heavy debris surcharge | $50 – $150 | Homes with multiple shedding pets or recent renovation dust |
| Mold remediation referral | Varies | Duct cleaning alone does not fix water intrusion; we refer out |
Those numbers reflect what the equipment actually does. A Rotobrush rotary brush system loosens debris from the inside wall of the duct, and a Nikro negative-air machine pulls the loosened material out through a HEPA filter instead of pushing it into your living room. Doing it right takes longer than running a shop vac up to a register, and that time is the difference between a real cleaning and a visual one.
What pushes a Dallas job higher: two HVAC systems, a home over 2,500 square feet, inaccessible duct sections buried in vaulted ceilings, and heavy buildup from pets or a recent remodel. What keeps it lower: one system, a clean maintenance history, and scheduling duct cleaning at the same time as dryer vent work. Read more about what our home service covers before you book.
What Affects Air Duct Cleaning Pricing in Dallas
Dallas is not a soft market for this work. Between the clay soil, the humidity swings in spring, and the amount of time our HVAC systems run from May through September, ducts here collect a specific mix of dust, pollen, and, in some homes, attic insulation particles. Here are the factors that move the price.
- Number of HVAC systems. A two-story home in Plano or Frisco almost always runs two systems. Each one has its own supply and return network, so the job roughly doubles in scope. A single-system ranch home in East Dallas is a different job entirely.
- Number of vents and registers. Base pricing covers a set vent count, usually 10 to 12. Beyond that, expect $15 to $35 per vent. Older homes in Oak Cliff with added-on rooms often have more registers than the original design intended.
- Duct access and attic conditions. Dallas attics hit 140°F in July. Ducts routed through tight, cathedral, or low-clearance attic space take longer and require more careful setup. That labor shows up in the quote.
- Level of contamination. Homes near new construction in Uptown or the Design District pull in drywall dust. Homes with cats and dogs pull in dander. Both add cleaning time, and the heavier one carries a surcharge.
- Duct material. Most Dallas homes use flex duct, which is fast to clean. Older homes with rigid sheet metal or duct board lining need a different brush technique and sometimes a mastic touch-up afterward.
- Whether you add duct sealing. Air duct cleaning and duct sealing are two different jobs. Sealing uses mastic to close the leaks that push conditioned air into your attic. In Dallas, where summer cooling bills carry real weight, sealing often pays back faster than cleaning alone.
One more local factor worth naming: pollen season. Dallas sits in one of the heaviest tree pollen corridors in the country, and March through May pushes fine particle loads through return ducts. Homes that clean in late spring tend to stay cleaner into the following year.
How to Save on Air Duct Cleaning
You do not need to chase the lowest bid to save money. You need to avoid the job that has to be done twice.
- Bundle duct cleaning with dryer vent cleaning. The setup is already on site, so the combined price is lower than two separate visits. Dryer vent cleaning runs $125 to $225 on its own, and most Dallas households need it more often than they think.
- Clean on a schedule instead of on a crisis. A home cleaned every three to five years with low contamination costs less than the same home cleaned after a decade of buildup. The labor difference is real.
- Get the price in writing before the visit. A written price is the single best protection against a surprise upcharge. If a company will not put numbers on paper before they arrive, that tells you something.
- Ask what equipment they use. If the answer involves negative-air and rotary brush systems by name, the company is doing the real job. If it involves a shop vac and a leaf blower, you are paying for dust redistribution.
- Handle filter maintenance yourself. Changing your HVAC filter on schedule is free and keeps duct buildup slower between professional cleanings. It does not replace the cleaning, but it stretches the interval.
We give free estimates, and that means a real range for your specific home, not a phone guess. Call (361) 326-5060 for yours. If you are comparing us to another quote, ask both companies the same question: what is written down, and what happens if the work fails within a year? We answer that second part with the 365-Day Done Right Promise, which is included in writing on every job. If our work fails inside a year, we come back and make it right at no charge, and that includes a free second visit. It is not a negotiation; it is the standard.
What the 365-Day Done Right Promise Actually Covers
Most duct cleaning companies offer a verbal “satisfaction guaranteed” and nothing else. Ours is written, it lasts a full year, and it names the remedy: if the repair fails within twelve months, we return and fix it at no charge, including a second visit. That covers the workmanship on the cleaning and on any duct sealing we performed.
Here is why this matters in practice. Duct sealing done poorly will re-open at the mastic joint when Dallas attics swing from 140°F in August to freezing in a January cold snap. A crew that did not prep the surface or did not let the mastic cure correctly will not know. We will. And we will come back on our own dime. That is the difference between hiring a price and hiring a standard.
The Garrison Code governs how our technicians behave on every job: arrive inside the quoted window, price in writing before the work starts, complete the job by the book, and leave the site clean. Our technicians are background-checked and uniformed, so you know who is walking into your home before they knock. When you call, a live person answers, day or night. That is a low bar, and it is still not the norm in this trade.
Frequently Asked Questions About Air Duct Cleaning Cost
How much does air duct cleaning cost in Dallas?
Air duct cleaning in Dallas runs $350 to $700 for a single-system home and $600 to $1,200 for a home with two systems. The range reflects vent count, contamination level, and attic access. Call (361) 326-5060 for an exact quote, and our estimates are free.
Is duct cleaning worth the money?
It is worth it at $350 to $700 if your ducts carry heavy dust, pet dander, or post-renovation debris, or if anyone in the home has allergy symptoms that track with HVAC season. It is not worth it if a $99 coupon is the only reason you called. A real cleaning uses negative-air and rotary brush equipment, and that equipment costs a company real money to run.
How often should ducts be cleaned in Dallas?
Every three to five years for most Dallas homes, and more often, closer to every two to three years, if you have multiple pets, a recent remodel, or a household member with respiratory sensitivity. Dallas pollen loads in spring and the length of our cooling season both push toward the shorter end of that range.
Can you clean my ducts the same day I call?
Often yes, depending on route availability and the size of the job. A single-system home can usually be scheduled faster than a two-system home, and dryer vent cleaning can often be added on the same visit. A live person answers our line 24/7, so call (361) 326-5060 and we will tell you what is open.
Do I need duct sealing, or just cleaning?
They solve different problems, and duct sealing costs $450 to $1,500 depending on the linear feet of accessible duct. Cleaning removes what has accumulated inside the ducts. Sealing closes the leaks that push conditioned air into your attic before it reaches the room. In Dallas, where the cooling season runs long, sealing typically pays back in lower summer bills if your ducts are leaking. We also publish Houston air duct cleaning costs for Texas homeowners outside the metroplex. If you are unsure, we will tell you which one your home actually needs.
How We Compare to the Dallas Average
Plenty of Dallas duct cleaning companies will beat our number on the phone. Fewer will match it at the door. The pattern our customers describe is familiar: a low quote over the phone, a higher number once the technician sees the attic, then a hard sell on add-ons before he will start. We price in writing before we touch anything, and that number does not change.
Our equipment is professional-grade, from the same brands commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. If a company cannot name the equipment they use, ask why.
Hollis Air Duct Cleaning has been in business as part of the Garrison Partners family since 2004, and every location is independently owned and operated under The Garrison Standard. That standard exists because the trade earned a reputation for no-shows, moving prices, and crews who leave a mess and disappear. We run the opposite way on purpose.
