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.

We’ve worked in Denton long enough to know that a house near Texas Woman’s University built in 1954 doesn’t have the same ducts as a 2005 subdivision in Southridge. The TWU area, the historic downtown square, and the post-war neighborhoods off University Drive each present their own problems: original galvanized steel, crushed runs in pier-and-beam attics, and systems that have been pulling attic air for decades. Our Air Duct Cleaning team treats every job by what we find, not by a flat-rate menu.

We know Denton’s rental cycles. Landlords near UNT and TWU often need duct cleaning between tenants on tight move-in/move-out schedules. We coordinate with property managers, provide written documentation of what was found and what was done, and price it before we start so there are no invoice surprises when the new tenant is scheduled to arrive Friday.
Vent Cleaning in Denton
Vent cleaning in Denton is what most homeowners picture when they call us: the visible supply and return registers brushed, vacuumed, and wiped down. But in Denton’s older neighborhoods, we regularly find that the registers are the cleanest part of the system. A proper vent cleaning here includes camera inspection of the branch lines, because the real blockage is often fifteen feet back in a crushed or disconnected galvanized run.
For a typical Denton home, vent cleaning runs $150 – $300 when the ductwork behind it is intact. When we find disconnection or heavy debris, we stop and show the homeowner what the camera sees before quoting any additional work.
Register and Grille Restoration
Original metal grilles in Denton’s historic homes and downtown loft conversions are often painted over multiple times, with reduced free area and accumulated grime. We remove, clean, and restore airflow through the existing hardware rather than replacing character details that match the building’s era.
Branch Line Cleaning
The flexible duct or hard pipe between your register and the main trunk carries the actual airflow. In Denton’s pier-and-beam construction, these lines often sag, crush, or disconnect at joints. We camera every branch before we quote, so you know whether you’re paying for cleaning or for reconnection and sealing.
Air Duct Repair in Denton
Air duct repair in Denton is not a separate service from cleaning for most of the homes we see; it’s the necessary follow-through once we find what’s actually wrong. In the TWU-area rental stock, our techs regularly discover 1950s galvanized trunk lines disconnected from the plenum, crushed in attic spaces too low to stand in, or pulling fiberglass insulation through gaps that were never sealed when the system was installed.
Repair work in Denton typically adds $200 – $500 to a cleaning job, depending on whether we’re resealing joints, reconnecting a trunk line, or replacing a crushed section with properly sized duct. We write the full price before we cut or seal anything.
Plenum Reconnection and Sealing
The plenum is the box that connects your air handler to the main trunk line. In older Denton homes, this joint is often held together with failing tape or nothing at all. We reseat the connection and seal it with mastic and foil tape, then test to confirm the system is pulling conditioned air, not attic air.
Crushed Run Replacement
Flexible duct in tight pier-and-beam attics gets stepped on, sat on by storage, or compressed by decades of shifting insulation. When a run is too damaged to restore airflow, we replace it with properly supported duct sized to the register’s needs, not whatever was cheapest in 1962.
Trusted Brands We Service in Denton
Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation of debris inside duct walls, Nikro negative-air machines for controlled extraction without blowing contaminants into the living space, and HEPA filtration from Abatement Technologies to capture what we pull out. For homes needing upgraded filtration after cleaning, we stock Honeywell, Aprilaire, and Guardsman products with fast turnaround from our Dallas-Fort Worth supply chain. We don’t sell what we wouldn’t install in our own homes, and we explain what each piece of equipment does while it’s running in yours.
Common Air Duct Cleaning Problems We See in Denton Homes
- Disconnected trunk lines in TWU-area rentals. The main galvanized trunk separates from the air handler plenum over decades of vibration and thermal cycling, pulling unfiltered attic air through the system. Camera inspection finds it; mastic and mechanical fastening fix it.
- Insulation fiber contamination from poor sealing. In Denton’s pier-and-beam homes, attic insulation gets drawn into ducts through gaps at register boots and plenum joints. Standard brushing spreads it; HEPA negative-air extraction with Rotobrush agitation removes it.
- Humidity-caked debris on blower motors and coils. Denton’s May-through-September cooling season packs dust and mold spores onto wet evaporator coils. Cleaning ducts without addressing the air handler and coil leaves the source of contamination intact.
- Crushed flexible duct in downtown loft retrofits. Century-old buildings converted to residential use often have HVAC systems shoehorned into spaces never designed for them. Ductwork runs through chases too small, with sharp bends and compression points that strangle airflow.
Pricing for Air Duct Cleaning in Denton, TX
A typical full residential system cleaning in Denton runs $350 – $650, depending on the number of air handlers, the accessibility of the ductwork, and whether we find conditions that require repair. Vent cleaning alone, when the branch lines are intact, is $150 – $300. Air duct repair work, including plenum reconnection, sealing with mastic, or crushed run replacement, adds $200 – $500.
We do not quote per-vent pricing. The number of registers in your home does not determine the labor or equipment required. One flat price per system, agreed in writing before work starts. If camera inspection reveals additional problems, we show you the footage and write a separate price for the repair. No invoice grows at the door.

FAQs About Air Duct Cleaning in Denton
Because Denton’s housing stock, especially near TWU and in the historic districts, includes thousands of homes with original 1940s-1970s galvanized ductwork that has disconnected at joints, crushed in attics, or never been properly sealed. A technician who only brushes the registers misses these problems. We camera-inspect first, so you know whether you’re paying for cleaning or for the repair that actually restores airflow. Call (361) 326-5060 for a free estimate.
Most Denton landlords schedule duct cleaning between tenants, or every two to three years for long-term rentals. Student turnover is high, and the combination of original ductwork, heavy use, and brief occupancy windows means allergens and odors accumulate fast. We coordinate with property managers for tight move-in schedules and provide written documentation of work completed. Call (361) 326-5060 to set up a rental property plan.
Yes, particularly in systems that have not been cleaned through multiple humid summers. Denton’s subtropical climate keeps evaporator coils wet from May through September, and dust that settles on the coil becomes a growth medium. We inspect the coil and blower during every full system cleaning, because treating ducts alone while leaving a contaminated coil does not solve the problem. Call (361) 326-5060 if you smell mustiness when the system runs.
Vent cleaning addresses the visible registers and the short branch lines behind them. Air duct cleaning includes the main trunk lines, the plenum, the air handler, and the coil. In Denton’s older homes, vent cleaning alone is rarely sufficient because the real problems are in the trunk and plenum, not the register. We price by what your system actually needs, not by a menu that assumes every house is the same. Call (361) 326-5060 to discuss what we would recommend for your home.
Carefully, and only after camera inspection. Downtown loft conversions often have ductwork retrofitted into spaces never designed for HVAC: tight chases, sharp bends, and mixed materials from multiple renovation phases. We use flexible rotary tools and controlled negative-air extraction rather than aggressive brushing that could damage fragile or irregular runs. Every job starts with a written price based on what we see in the camera. Call (361) 326-5060 for a downtown Denton estimate.
On a TWU-area 1950s pier-and-beam rental, our tech camera-inspected the supply and return ducts and found the main trunk disconnected from the air handler plenum and full of attic insulation fibers drawn in through poor sealing. We set up negative pressure with a HEPA filtration unit, used agitation tools and Rotobrush to remove the fiber-laden debris, then resealed the plenum and registers with mastic and foil tape so the system pulled from the house, not the attic. The landlord had a written price before we started, before-and-after photos of the camera footage, and a 365-Day Done Right Promise in hand when we left.
That’s how we work in Denton. If your ducts haven’t been inspected in years, or if you’ve had a cleaning that didn’t seem to change anything, call (361) 326-5060. We’ll show you what we find before we quote a dollar.
