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.

Why Cardinal Air Duct Cleaning Is Iowa Colony’s Preferred HVAC Cleaning Company
We are not a national chain dispatching a subcontractor you have never heard of. Cardinal Air Duct Cleaning offers Air Duct Cleaning in Iowa Colony as part of the Relay Home Co. family, which was founded in 2005, and every booking is held to The Relay Visibility Guarantee. That means a live trackable arrival time, a written price before work starts, before-and-after photo documentation of your own ducts, and a digital invoice you can pay from your phone. No guessing. No bait pricing.
Omar Haddad leads our local operation, and the standard he enforces is simple: technicians show up in uniform, they are background-checked, and you know their name before they knock. Calls are answered by a live person 24/7. Iowa Colony residents who have used us repeatedly cite the same thing: the price on the written estimate matched the invoice exactly, and the photos showed what was actually removed from their system.
We know the difference between the 1960s ranch homes around the original townsite and the new two-story builds going up east of the growth corridor. That local knowledge changes how we set up equipment, and it is why we can respond to an Iowa Colony address without guessing at what we will find when we open the air handler.
AC Coil Cleaning in Iowa Colony
AC Coil Cleaning in Iowa Colony means pulling the evaporator coil access panel and removing the mat of dust, pet hair, and bio-growth that builds up on the coil fins between April and October. In this part of Brazoria County, we see coil fouling get worse faster than in drier Texas markets because of the humidity that hangs over Iowa Colony from the Gulf. A dirty coil costs you airflow and cooling capacity even when the rest of the duct system is clean, so we treat it as part of the job, not an upsell. A standalone evaporator coil cleaning in Iowa Colony runs $180 – $290; when it is bundled into a full HVAC cleaning, the combined price is the flat-rate figure above.
What Actually Happens During a Coil Cleaning
We remove the coil access panel, inspect the fins and drain pan, then apply an approved coil cleaning solution and rinse it through under controlled pressure so the debris goes into the drain pan and out, not onto the blower below. After the fins are clear, we check the condensate drain line for the algae and sludge that Gulf Coast humidity promotes. One of the most common calls we get from Iowa Colony homeowners is a pan overflow caused by a clogged line, not a mechanical failure.
Signs Your Iowa Colony AC Coil Is Due
The air coming out of your supply registers will be cool but weak, your electric bill creeps up through summer, and the unit cycles longer to hold the same thermostat setting. Those symptoms on an Iowa Colony ranch home with the original slab-embedded flex duct usually point to coil restriction compounding an already restricted duct run. We clean the coil, check the duct, and show you the after photos so you can see the bare metal and coil fins again.
AC Cleaning in Iowa Colony
AC Cleaning in Iowa Colony covers the full indoor air-moving system: the return plenum, the blower wheel and blower housing, the evaporator coil, the supply plenum, and the branch ducts that carry air to each room. Where a cheaper quote might just vacuum the registers, we run negative-pressure extraction through the system, which means the loosened debris goes straight into a HEPA-filtered Nikro vacuum instead of drifting back through your living room. In Iowa Colony’s older ranch homes, that step matters because the flex branches under the slab have no access to be hand-brushed. On newer two-story homes, the trunk-and-branch attic layout means we use Rotobrush agitation on each branch run to dislodge debris from the trunk connections.
Older Ranch Homes vs New Two-Story Builds
In the 1960s-era single-story streets around the original Iowa Colony townsite, most homes still run the original slab-embedded flex duct. That duct sags between supports, pooling dust and construction debris at the low spots, which is exactly where airflow stalls first. We set up negative pressure at the supply plenum to pull downstream and use camera inspection to find those pool points before agitation. If a section is collapsed rather than just dirty, source removal will not fix it, and we will show you the camera footage so you can see why a replacement run makes more sense than cleaning.
Sealed Attic Systems in Newer Growth Corridor Homes
Newer two-story homes along the Brazoria County growth corridor often have sealed attic trunk-and-branch systems with far more registers than the ranch homes. A per-vent price on those plans balloons fast, so we quote one flat price per system and clean the entire duct path regardless of register count. The mechanical room in these homes is tighter, so proper negative pressure and containment are the difference between removing dust and recirculating it. We use Abatement Technologies containment units on sealed attic jobs to keep negative air where it belongs.
Trusted Brands We Service in Iowa Colony
We maintain and clean systems from the brands Iowa Colony builders installed most often in the last two decades, along with filtration products from Honeywell, Aprilaire, and Guardsman. Whether your air handler is a high-efficiency variable-speed unit in a new Meridiana build or a basic single-stage system in a ranch off Highway 6, our techs have the training and the brand-specific access points mapped. We also stock common Aprilaire media filters and Honeywell electronic air cleaner parts on our service vehicles, which means fewer parts runs and a faster day for you when a cleaning uncovers a workable but tired filtration component.
Common HVAC Cleaning Problems We See in Iowa Colony Homes
- Slab-layer flex duct sagging in 1960s ranch homes. The original flex runs pooled with dust and construction debris at the low spots. Camera inspection finds these restrictions before we spend time agitating a run that needs replacement, not cleaning.
- High CFM vacuums on tight new builds without proper negative pressure. In a sealed two-story off the growth corridor, a vacuum pulling more air than the system can replace will draw makeup air back through the return and re-deposit dust downstream. Negative pressure and containment are mandatory on those jobs.
- Per-vent pricing on newer plans with many registers off few trunks. Newer Iowa Colony homes often have a dozen or more registers, and per-vent pricing turns that into a bloated invoice while the main trunks still go uncleaned. One flat price per system solves it.
- Coil fouling accelerated by Gulf humidity. Iowa Colony sits close enough to the coast that spring and summer humidity keep coil surfaces damp longer, which builds the mat of dust and bio-growth faster than in drier Texas markets. We see coil cleanings ignored on systems that look halfway presentable at the return grille, and the cooling loss comes from the coil, not the visible register.

FAQs About HVAC Cleaning in Iowa Colony
Every 3 to 5 years for most Iowa Colony homes, but the ranch houses with the original slab-embedded flex duct often need a first cleaning sooner because that layout accumulates debris at the sag points faster than a sealed attic trunk-and-branch system. If you have been in the home less than two years and do not know the duct history, a camera inspection will tell you in minutes whether cleaning is warranted. Call (737) 727-2314 and we will do that inspection honestly before recommending any work, and the estimate is free.
One flat price per system, always. We do not price per vent because per-vent pricing on newer Iowa Colony two-story plans with many registers off few trunks runs the bill up past what the job should cost, and it still skips the main trunk runs. The written price you get before we start covers the entire duct path regardless of register count.
Yes. Every Cardinal Air Duct Cleaning job includes before-and-after photo documentation of your own system, from the coil to the plenum to the inside of the branch runs. The Relay Standard means the arrival window is trackable, the price is written before work starts, and the photos are shown to you before we leave, not emailed two days later.
On a two-story home with a sealed attic trunk-and-branch system, we set up negative-pressure extraction at the air handler, run Rotobrush agitation through each branch run, clean the blower wheel and housing, clean the coil, and contain the loose dust with an Abatement Technologies unit so it does not get pulled back through the return. The full duct path gets cleaned, not just the supply registers. One flat price covers both stories.
No, and we would rather be honest than overpromise. HVAC cleaning is a scheduled job, and a proper cleaning on an Iowa Colony home takes half a day from setup to after photos. What we do promise is a live trackable arrival window, a written price before work starts, and a call answered by a live person 24/7 when you are ready to book. Call (737) 727-2314 and we will get you on the schedule at the next available slot that fits your day.
