Cardinal Air Duct Cleaning is part of the Relay Home Co. family, founded 2005, and we operate under The Relay Visibility Guarantee.

No four-hour windows. No price that shifts when the technician walks through the door.

Our Houston customers tell us the same thing: they knew exactly who was coming, what the work would cost, and what was actually done. The technicians are background-checked and arrive in uniform. You’ll know your tech’s name before they ring the bell. Omar Haddad leads our Houston team, and he holds every job to the 365-Day Done Right Promise: if the work isn’t right within 365 days, we return and correct it at no charge. That applies to every booking. No exceptions.

AC Coil Cleaning in Houston

AC coil cleaning in Houston is the single highest-impact part of any HVAC cleaning, because our Gulf Coast humidity keeps the evaporator coil wet for most of the year. That wet surface traps dust, lint, and airborne biological material. Within a season or two, the coil can look like it’s wearing a sweater. When that happens, your system works harder to move the same amount of air, your electric bill climbs, and the air you breathe passes over a dirty surface every single cycle.

What the Job Involves

We remove the coil access panel, inspect the drain pan, and clean the coil fins using professional-grade equipment from Abatement Technologies. The drain line gets flushed too, because a clogged condensate line in Houston means water backing up into the pan, which means rust, biological growth, and eventually a leak onto your closet or garage floor. A coil cleaning typically runs $180 – $340 when bundled with a full system cleaning.

Signs You’re Overdue

Water staining near the air handler, a faint musty smell when the blower kicks on, or a steady rise in summer electric bills often traces back to a blocked coil. If you haven’t opened the coil cabinet since the system was installed, you’re not alone. Most Houston homeowners never see it. We photograph the before and after so you can see exactly what you paid for.

AC Cleaning in Houston

AC cleaning in Houston means treating the whole system, not just the return registers. The blower wheel, the housing, the coil, the drain pan, the supply and return duct runs, and the return grille all collect material differently. A blower wheel caked in hardened dust throws the fan out of balance and shortens the motor’s life. That’s a $600 – $1,200 repair on most systems, and it’s almost always preventable.

Blower and Air Handler Cleaning

We pull the blower assembly, clean each fin on the wheel, vacuum the housing, and check the amp draw before and after. We regularly see blower motors in older Houston homes pulling high amps because the wheel is carrying years of accumulated crud. Once cleaned, the amp draw drops back into normal range. That is measurable. It’s not an opinion.

Supply and Return Duct Runs

Using Rotobrush agitation and a Nikro HEPA vacuum under negative pressure, we remove the material that loosens, rather than blowing it into your living room. The containment unit runs the entire time. Debris leaves the duct, travels straight into the vacuum, and never enters the breathing space. For a typical single-system Houston home, full AC cleaning including ducts, coil, and blower runs $350 – $650.

Trusted Brands We Service in Houston

We work on every major residential brand found in Houston homes: Carrier, Trane, Lennox, Rheem, Goodman, American Standard, and Daikin. Because we service Houston specifically, we stock common condensate fittings, drain pan treatments, and coil cleaning solutions that local supply houses run short on during the summer rush. If you need a Guardsman coil treatment or a replacement Aprilaire filter after the cleaning is done, we carry them on the truck. No second trip, no waiting on a part from Dallas.

Common HVAC Cleaning Problems We See in Houston Homes

• Coil cabinets with standing water chronic in attic and closet installs. Houston’s dew point stays high most of the year, and a poorly sloped drain pan never fully empties. That standing water is where the growth starts, and a ducts-only cleaning misses it entirely.
• Dust accumulation worse than expected for a one-story home. Many Houston houses run the blower fan continuously for air circulation, which pushes more total air volume through the ducts than cycling systems. More air means more deposition, especially on first-floor return runs near the garage.
• Flex duct runs crushed or disconnected in older bungalows. In neighborhoods like the Heights and Montrose, original 1950s and 60s duct layouts have been added onto over decades. We regularly find collapsed flex runs that were feeding dust into the blower and choking return airflow.
• Pet hair and dander compacted in return cavities. With so many families keeping dogs indoors through Houston’s hot months, the return grille acts like a lint trap. In homes with two or more medium-sized dogs, we often find the return cavity half-filled with hair within three years of the last cleaning.
