Fast, Reliable HVAC Cleaning Across Keller
HVAC cleaning in Keller typically runs $425 – $685 for a full system clean in a standard single-family home, and the job usually takes 3 to 5 hours. Keller homes built in the 1990s and early 2000s often need more than a surface clean because flex ducts in the attic have sagged, kinked, or pulled loose over time. We schedule directly with Keller homeowners and show up with a written price before any work starts. Call (817) 730-6759 for a free estimate.
Why Cardinal Air Duct Fort Worth Is Keller’s Preferred HVAC Cleaning Company
Keller homeowners call us because we know exactly what happens inside local ductwork after 20 or 30 years. Omar Haddad leads the crew, and every technician who knocks on a Keller door is background-checked, uniformed, and trained on professional-grade equipment, not a truck-mounted shop vac. We run Rotobrush rotary brush systems and Nikro HEPA vacuums because Keller’s older flex duct needs real agitation and negative-pressure extraction, meaning the loosened debris goes straight into the vacuum, not back into your living room.
Part of the Relay Home Co. family, founded in 2005, we hold every Keller job to The Relay Standard: a live trackable arrival time, before-and-after photo proof, and a digital invoice you can pay from your phone. That is not a premium add-on. It is how every booking works. The 365-Day Done Right Promise backs the entire clean. If the work is not right within 365 days, we return and correct it at no charge.
Styles & brands we work with
AC Cleaning in Keller
AC cleaning in Keller is a deeper job than most homeowners expect, because the cooling side of your system works hardest during our long, humid summers. On a typical Keller two-story, we pull the blower wheel, clean the evaporator coil, flush the condensate pan and line, and then clean the supply and return duct runs from the attic down. In homes around Hidden Lakes and Marshall Ridge, we routinely find the blower caked with a gray film of dust and pet hair that cuts airflow to far bedrooms.
Blower and coil access in Keller homes
Most Keller furnaces sit in an attic closet or a garage utility room, and blower wheels here collect a particular mix: construction dust from the original build, pollen from native oaks and pecans, and fine clay dust that blows in during dry, windy stretches. Removing and cleaning the blower restores static pressure, which is what actually pushes cool air to the second floor.
What Keller homeowners notice after a full AC clean
The rooms farthest from the unit stop feeling stuffy. The system cycles less. Some homeowners in Marshall Ridge tell us their allergies settle within a week because we removed years of accumulated pollen and dust from the coil and duct interior. The clean typically runs $450 – $650 depending on system size and how much debris has to be extracted.
Evaporator Coil Cleaning in Keller
Evaporator coil cleaning in Keller matters because a dirty coil is the single biggest reason AC systems in 1990s and early 2000s homes underperform. The coil sits directly in the airflow path, and in Keller’s humid summers it condenses moisture constantly. That damp surface grabs dust, pollen, and pet dander, turning into a biological film that insulates the coil and blocks heat transfer. Your system runs longer, your upstairs stays warm, and your electric bill climbs.
How we clean a coil without flooding the attic
We use a foaming, self-rinsing coil cleaner applied at low pressure, then capture the runoff in a pan treatment that keeps the drain line clear. No high-pressure water in an attic over finished ceilings. The coil treatment we apply afterward slows re-soiling and lets the coil shed condensation more cleanly for the rest of the season.
Keller coil cleaning cost
A standalone evaporator coil cleaning in Keller runs $250 – $400. When we do it as part of a full HVAC Cleaning service, the combined price is lower than doing each job separately. We always hand you a written price before touching a single duct.
Trusted Brands We Service in Keller
Our crew works on all major residential systems and we stock common consumables for Keller jobs, including Guardsman and Aprilaire filtration products. The Rotobrush system we use is sized for the attic access and long flex runs typical of Keller homes. We also run Abatement Technologies containment units when we open a heavily loaded duct in a finished attic so the debris never migrates into the living space. The tools match the house.
Common HVAC Cleaning Problems We See in Keller Homes
- Flex ducts that sag between trusses. In Keller attics, the temperature swings cause the plastic inner liner to stretch and droop in low spots. Dust collects in the sag and airflow to far bedrooms drops off. We re-support and re-tension the run, then clean the interior.
- Ceiling returns with undersized filters. Early-2000s homes around Hidden Lakes often have a single ceiling return with a 1-inch filter slot. That filter loads fast, the blower starves for air, and dust recirculates through the supply registers. We clean the return and recommend a properly sized media filter setup.
- Construction debris in newer Woodland Springs homes. Drywall dust, sawdust, paint chips, and occasionally a fast-food wrapper stay in the supply ducts after the builder’s final clean. The first homeowner dusts the house every week and never catches up until the ducts are opened and extracted.
- Disconnected register boots in the attic. A duct pulls free of its metal boot and conditioned air dumps into the insulation while bedrooms stay hot. We camera-inspect every run after cleaning to catch this exact failure, which is common in Keller but rare in newer rigid-metal duct systems nearby.

FAQs About HVAC Cleaning in Keller
The short answer is heat and gravity over 20-plus years. Flex ducts in Keller attics are attached with plastic zip ties and foil tape to metal register boots. Keller’s summer attic temperatures, which routinely exceed 130 degrees, soften the tape adhesive and the plastic outer liner. The duct sags between trusses, pulls away from the boot, and conditioned air blows into the insulation. We fix it by re-seating the inner liner, sealing the connection with mastic and a stainless band clamp, and re-supporting the run every 4 feet. That repair alone often solves a perpetually warm bedroom. Call us at (817) 730-6759 if you suspect this in your home.
Every 3 to 5 years for most Keller homes, and every 2 to 3 years if you have pets, allergy sufferers in the house, or a ceiling return with a 1-inch filter. Keller’s spring oak and pecan pollen load is heavy enough that a single season can leave a visible yellow-green dust on every supply register. That pollen enters the return, passes through an undersized filter, and gets distributed through the whole system. If you replace your filter monthly and still see dust accumulating on furniture within days, the ducts are likely the reservoir. Call us and we will camera-inspect before quoting anything.
Yes, and we clean those homes differently. The undersized filter means the blower has been pulling harder against a restricted return, which pulls more dust into the return chase itself. We remove the grille, clean the return box and the first several feet of the return duct by hand before running the Rotobrush, because that section is often packed with a felt-like layer of dust and filter fibers. We also check the filter slot and can install a media filter cabinet that holds a 4-inch filter, which gives the blower more surface area and catches far more pollen. The cleaning works either way, but the filter upgrade keeps it clean longer.
A crushed or kinked flex duct run costs $75 – $150 to repair when we find it during a cleaning, depending on the length of the replacement flex and how accessible the attic run is. We do not charge a separate diagnostic fee when the damage is found during a scheduled clean. If a run is beyond repair, we quote replacement by the linear foot and hand you that price in writing before cutting anything. The Written Price Before Any Work Starts rule applies to repairs just as strictly as to cleanings.
Because the ducts themselves are the source, not the filter. In Keller two-story homes, the longest supply runs are often flex duct laid across the attic floor or supported loosely between trusses. Those long runs are where dust has been accumulating for years, and when you install a fresh filter, the slight change in airflow pressure dislodges some of that dust and pushes it to the farthest registers. The fix is to clean the full supply run and re-support the duct so dust cannot settle in low spots again. We see this constantly in Hidden Lakes and Marshall Ridge, and cleaning resolves it in a single visit.
