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.
Fast, Reliable HVAC Cleaning Across Denton
HVAC cleaning in Denton means cleaning the entire system, not just the vents: the evaporator coil, blower motor, air handler, and duct runs that move conditioned air through your home. Most standard whole-system cleanings for a typical Denton home run $550 – $1,100, depending on system size and how much buildup has accumulated. We serve the whole city, from the streets around the Square to newer subdivisions along FM 428, and we give you a written flat price before any work starts. Call (737) 727-2314 for a free estimate.
Denton’s housing stock is genuinely mixed. You have 1950s bungalows near Texas Woman’s University with duct runs buried in attics that bake at 140°F in August, and you have tightly-built new construction off Loop 288 with sealed but undersized returns. That range is exactly why we quote by the system, not by the vent. A per-vent price tells you nothing about how much debris is sitting in a trunk line or plenum you cannot see. Our HVAC Cleaning team walks the system first, then hands you a written price that does not change at the door.
Why Cardinal Air Duct Cleaning Is Denton’s Preferred HVAC Cleaning Company
We are part of the Relay Home Co. family, founded in 2005, and every job we run in Denton is held to The Relay Visibility Guarantee. That means a live trackable arrival window, before-and-after photos of your actual ducts, and a digital invoice you can pay from your phone before we leave the driveway. Denton homeowners tend to be phone-first and detail-oriented, and we built our process around that: you always know who is coming, what they will do, and exactly what it costs before they touch a single register.
Omar Haddad leads our local team, and he insists on one standard across every job: if the work is not right within 365 days, we return and correct it at no charge. That is not a limited offer, and it never expires. It applies to every booking, every time. Denton customers who have used us before know the drill: background-checked, uniformed technicians running Rotobrush agitation tools, Nikro HEPA-filtered negative-pressure vacuums, and Abatement Technologies containment units. No truck-mounted shop-vac shortcuts. No vague estimates. No phone tag.
Furnace Cleaning in Denton
Furnace Cleaning in Denton usually comes down to the blower motor and the heat exchanger, because that is where the debris actually lands after a Texas winter of cycling heat through dusty attic air. In older Denton homes near Bell Avenue or around the UNT campus, we often find the blower wheel caked with a gray film of drywall dust and insulation fibers. That buildup reduces airflow, makes the system run longer, and pushes the motor harder than it was built to run. A full furnace cleaning, including blower wheel removal, heat exchanger inspection, and housing cleanup, typically runs $250 – $450 here, depending on access and the amount of buildup.
Blower Wheel and Motor Cleaning
The blower wheel is the part that actually pushes air. When it loads with dust, your system strains to move the same volume of air, and you feel it in uneven temperatures between rooms. We pull the wheel, clean it by hand where needed, and reassemble with the correct static pressure in mind, all covered under the same flat price you approved before we started.
Heat Exchanger Surface Cleaning
A fouled heat exchanger means heat is not transferring efficiently, but it also creates a fire-safety concern if buildup is heavy enough. We clean the accessible surfaces, visually inspect for cracks or soot streaks, and flag anything that looks like it needs an HVAC technician’s attention. You get photos of all of it, before and after, on your digital invoice.
AC Vent Cleaning in Denton
AC Vent Cleaning in Denton gets a lot of attention every spring, because once the pollen and construction dust settle, people notice what is blowing out of their registers. But vent cleaning alone is rarely the answer. In Denton’s older attic-duct homes, especially around Southridge and the neighborhoods off Teasley Lane, the vent grilles are only the visible end of a much larger duct run. If the trunk line and plenum are filled with debris, wiping the vent covers changes nothing about what is coming through them. A proper AC vent cleaning here means cleaning the entire branch and trunk system, not just the grilles, and it typically runs $400 – $800 for a full single-system home.
Full-Duct Source Removal
This is the real work. We use a Nikro HEPA-filtered vacuum to create negative pressure in the duct system, meaning loosened debris is pulled directly into containment instead of blowing back into your living spaces. A Rotobrush agitation line is fed through the trunk and branch lines to break loose the caked-on dust that a vacuum alone will not move. This is source removal, and it is the only method that matters on a system that has not been cleaned in years.
Evaporator Coil Access Cleaning
If the evaporator coil is loaded, no amount of duct cleaning will fix your airflow. We inspect the coil during the job, and when access allows, we clean it with appropriate coil cleaner and photograph the difference. This is the part most “duct cleaners” skip, because it adds time. It is also the part that determines whether your AC actually performs better afterward.
Trusted Brands We Service in Denton
We work around and service equipment from a range of manufacturers, and we carry common parts and filter sizes for Denton’s housing stock, including Aprilaire and Guardsman filtration products. If your system uses a Rotobrush-compatible access point or a Nikro-compatible HEPA port, we already know how to work with it. We also see plenty of Honeywell thermostats and zoning controls in Denton homes, and our techs are familiar with their wiring and common failure points. If a brand-specific part needs ordering, we handle it and keep you updated, no chasing required.
Common HVAC Cleaning Problems We See in Denton Homes
- Oversized, leaky duct runs in 1950s pier-and-beam homes. These homes near the Square often have trunk lines that were patched and repurposed over decades, and debris settles in the low points. A per-vent quote misses the actual problem entirely.
- Restrictive returns in new subdivisions. Builders sometimes size returns too small for the systems they install. We see this all over the new neighborhoods along FM 428 and near Rayzor Ranch. The result is a blower motor coated in dust within three years of construction.
- High-MERV filters making things worse. A dense filter on an already restrictive return starves the system. In Southridge and similar neighborhoods, we regularly find blower motors and coils loaded because the homeowner was told a MERV 13 was “better.” It chokes airflow and accelerates buildup.
- Drywall dust from renovations and new construction. Denton’s growth means renovation dust, and that dust is fine enough to pass through standard filters and settle directly on the coil and blower. If your home was renovated or you are near active construction, the ducts are collecting it.

FAQs About HVAC Cleaning in Denton
We price per system, not per vent. A typical Denton home runs $550 – $1,100 for a full HVAC cleaning including ducts, air handler, blower, and accessible coil. Per-vent pricing is common in this industry, but it tells you nothing about how much debris is sitting in your trunk line or plenum, and that is where the bulk of the buildup lives. Call (737) 727-2314 and we will quote the whole system before any work begins.
Most Denton homes do well with a cleaning every 3 to 5 years. Homes with pets, recent renovations, or active construction nearby may need it sooner, often every 2 to 3 years. If you cannot remember the last cleaning, or you can see dust buildup on the vent grilles and feel weak airflow at the registers, it is probably time. Call (737) 727-2314 and we will give you an honest assessment, not a sales pitch.
We run Rotobrush agitation systems and Nikro HEPA-filtered vacuum extraction units on our own work, and we are familiar with most residential equipment brands found in Denton homes, including Aprilaire, Honeywell, Guardsman, and Abatement Technologies filtration components. If your system has a brand-specific access point or filter cabinet, we know how to work with it, and we carry common parts locally to avoid waiting on shipments.

They are part of The Relay Visibility Guarantee and they are yours to keep. If you want proof the work was done, we show you proof, not a checklist. That is standard on every Denton job, no exceptions.
No, and we will not pretend to. A proper HVAC cleaning is a multi-hour job that requires scheduling, careful setup, and documentation. What we do promise is a live trackable arrival window, a written price in hand before work starts, and a live person on the phone at (737) 727-2314 whenever you call. If a company is advertising same-day duct cleaning around Denton, ask them what they are skipping to hit that timeline.
