What's included
What our HVAC duct cleaning includes
Every quote covers the full system, not a partial pass. Here is what you get when we show up, and what we treat as an add-on only if your system genuinely needs it.
Full supply and return cleaning
We clean every supply branch, every return run, the main trunk, and the plenum. Nothing gets skipped because it is hard to reach. If a run is inaccessible, we cut a proper access panel and restore it.
Air handler and blower cleaning
The blower wheel and cabinet collect dust that re-contaminates the ducts the moment the fan starts. We pull the panel, clean the wheel by hand, and wipe down the interior before we close it back up.
Evaporator coil cleaning
We clean the coil with approved coil cleaner and flush the condensate drain. A dirty coil is the number one reason Dallas systems lose cooling capacity, and it is included in our standard price.
Sanitizing and mastic sealing
After the debris is out, we fog the system with an EPA-registered sanitizer and seal accessible joints with mastic sealant. Loose duct tape gets replaced. This is what keeps the system clean long after we leave.
Camera documentation
You get before-and-after footage of your duct interior on our monitor, plus a written summary of findings. If we found something that needs a follow-up, you will see it and hear about it before we pack up.
Service overview
What HVAC duct cleaning Dallas TX actually involves
HVAC duct cleaning Dallas TX is a mechanical service that removes dust buildup, mold growth, and pest debris from every supply and return run in your system. We cut a negative air machine into the main trunk, then work each branch with a rotary brush and air whip so loosened debris travels out of the house instead of into your living room. Flexible duct and sheet metal duct get different tools, and we finish with a duct camera inspection so you can see the before and after on screen.
Dallas homes run their AC nine months a year, which means your ducts move more air than almost any other market in Texas. That constant cycling packs dust into the returns, and our summer humidity feeds mold growth on duct insulation and coil surfaces. If you have been searching for HVAC duct cleaning near me Dallas TX because of musty odors or allergy symptoms, the problem is usually a dirty return plus a leaking duct joint. We seal those joints with mastic sealant while we are in the attic.
The service timeline
How our duct cleaning process works
The process flexes to the condition, but these checkpoints keep decisions clear.
System inspection
We start with a duct camera run through the main trunk and a blower door test to measure how leaky the system is. You watch the monitor with us. This takes about 30 minutes and tells us whether you need standard cleaning or a heavier mold and pest treatment.
Negative air setup
We cut a service opening into the main trunk and connect a negative air machine with HEPA filtration. That machine holds the entire duct system under vacuum for the rest of the job, so nothing we loosen ends up on your furniture. Setup runs 20 to 30 minutes.
Mechanical agitation
Each branch gets worked with a rotary brush and an air whip, and we follow with a compressed air nozzle on the plenum and coil. Flexible duct gets a softer brush so the liner is not damaged. A typical three-bedroom Dallas home takes two to three hours for this stage.
Sanitizing and sealing
Once the debris is out, we fog the system with an EPA-registered sanitizer and reseal every accessible joint with mastic sealant. Loose duct tape gets replaced. This is the step that stops dust from re-entering through the attic in the first place.
Verification and walkthrough
We run the camera again so you can compare before and after, then restore the service opening with a proper access panel. You get a written summary of what we found, what we cleaned, and the filter size to buy going forward. Total on-site time is usually three to five hours.
Tools & methods
Tools and methods we use
Purpose-built equipment, used by trained technicians, so the job is done accurately the first time.
Negative air machine
Holds the entire duct system under vacuum during cleaning so loosened debris travels out of the building instead of into your living room. We size the unit to the square footage of the system.
HEPA vacuum
Captures particles down to 0.3 microns, including mold spores and fine dust that a shop vac would blow right back into the air. Every crew carries one on the truck.
Rotary brush and air whip
Mechanical agitation tools that scrub the duct walls and knock debris loose from every branch line. Flexible duct gets a softer brush so the inner liner is not damaged.
Duct camera
Lets us see inside the runs before and after cleaning, and gives you visual proof of the work. We also use it to locate pest entry points and mold growth.
Compressed air nozzle
Reaches the plenum and coil surfaces that brushes cannot touch, blowing debris into the negative air stream. Essential for the air handler cabinet.
Fogger
Applies EPA-registered sanitizer as a fine mist that coats the entire duct interior, including corners and seams. Used after debris removal, never as a substitute for it.
Blower door
Measures how leaky your duct system is before and after sealing, so you can see the actual improvement in static pressure rather than taking our word for it.
Use cases
When Dallas homeowners call us
These examples show how the service framework adapts rather than forcing every call through one repair.

Far North Dallas mold discovery
A musty odor appeared every time the AC started. The camera showed mold growth on the insulation near the air handler, and the coil was fouled with biological debris. → We scrubbed the affected runs, applied an EPA-registered sanitizer, and cleaned the coil. The odor was gone within 24 hours, and airflow at the farthest vent improved measurably.
Preston Hollow pest cleanup
Rodents had chewed through a flexible duct run in the attic and were using it as a highway. Droppings and nesting material created an odor that spread through the second floor. → We removed the contaminated section, replaced it with new flexible duct, HEPA-vac'd the trunk, and sanitized the interior. The odor cleared in a day and the system held pressure on the blower door test.
Problems we solve
Duct problems we fix in Dallas homes
Most Dallas duct complaints trace back to one of four causes. Here is what each one looks like and what we do about it.
Dust buildup choking the return runs
We cut a service opening into the trunk, connect a negative air machine, and work each return with a rotary brush and air whip. Once the debris is out, we seal the joints so attic dust cannot get pulled back in.
Mold growth on wet duct insulation
We identify the affected runs with a duct camera, scrub the growth off, and apply an EPA-registered sanitizer. If the insulation is saturated, we tell you straight that it needs replacing rather than cleaning, and we can handle that too.
Pest infestation inside the ductwork
We remove the contaminated material, HEPA-vac the run, sanitize the interior, and seal the entry points we find. If the flexible duct is chewed through, we replace that section rather than trying to patch it.
Leaking duct joints wasting conditioned air
We seal every accessible joint with mastic sealant, which holds up to attic heat far better than duct tape. On older systems we also check the plenum connections and the return drop, which are the two most common leak points.
Pricing process
What duct cleaning costs in Dallas
$350 - $1,100 depending on system size and contamination
Number of vents and returns
A 1,200 square foot bungalow with eight vents takes less time than a 4,000 square foot two-story with twenty. Each register and return adds cleaning and inspection time, which is the biggest driver of the final price.
Duct material
Sheet metal duct cleans quickly with a rotary brush. Flexible duct requires a softer touch and more passes, and if the inner liner is torn or collapsed, that section needs replacing rather than cleaning.
Mold or pest contamination
Standard dust is included in every quote. If we find mold growth or rodent debris, the job needs sanitizing and sometimes section replacement, which adds time and materials. We tell you before we start, not after.
How much does HVAC duct cleaning cost in Dallas TX?
Most Dallas homes run $350 to $700 for a full system, and larger two-story houses with multiple zones land between $700 and $1,100. Typical 2026 pricing in this area depends on the number of vents, whether you have flexible duct or sheet metal, and how much mold or pest debris we find. Coil cleaning and sanitizing are included in our quote, not tacked on later.
Does HVAC duct cleaning improve airflow in Dallas?
Yes, and the gain is usually measurable. A clogged return can cut airflow by 20 to 40 percent, which is why some rooms never get cool. After we clean the runs and seal the leaks, we often see static pressure drop enough that the system moves air the way it was designed to. You will feel it at the farthest vent first.
How often should HVAC ducts be cleaned in Dallas Texas?
Every three to five years for a typical Dallas home, and every two years if you have pets, allergies, or a recent remodel. This climate runs the AC hard from March through October, so dust and biological growth build faster here than in milder markets. If you notice musty odors or visible dust at the registers, do not wait for the calendar.
Can HVAC duct cleaning remove mold in Dallas?
It removes the mold and the food source it grows on. We scrub the affected runs, HEPA-vac the debris, then apply an EPA-registered sanitizer to the duct interior and clean the evaporator coil where condensation feeds growth. If the insulation itself is saturated, we will tell you straight that it needs replacing rather than cleaning.
