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.
Abatement Technologies Coil Cleaning: The Houston Owner’s Guide
Abatement Technologies coil cleaning in Houston typically runs $340-$580 for a full evaporator or condenser coil service on compatible systems, and we stock the compatible cleaning agents and tools for same-day scheduling when you call before noon. Most Houston owners realize their Abatement Technologies unit needs coil attention when the supply air feels lukewarm despite the blower running, or when their energy bill climbs 15-20% without explanation. The photo goes first. The pitch comes later, if it’s warranted.
Which Abatement Technologies Models This Applies To
Abatement Technologies builds coil-dependent equipment across several lines, and the cleaning approach differs by series. The CAP600-UV and CAP1200-UV air scrubbers use a 16x20x1 or 20x25x1 evaporator coil matrix that sits downstream of the UV chamber, identifiable by the yellow Abatement Technologies label on the blower housing. The HEPA-AIRE and PREDATOR portable units use a smaller 12×12 coil pack that slides out on rails, not bolts, so the cleaning protocol is lower-pressure and chemical-focused rather than mechanical brushing. The PAS2400 and PAS5000 whole-house negative-air systems use a dual-coil arrangement, one pre-filter and one post, and mixing up which coil gets which cleaning agent is a common mistake that strips the hydrophilic coating.
We carry OEM-spec foaming cleaner and the lower-pH rinse Abatement Technologies recommends for the UV-series units, plus compatible aftermarket equivalents from Guardsman that match the NSF rating without the OEM markup. For units still under manufacturer warranty, we document the cleaning with before-and-after photos and a service report that satisfies Abatement Technologies’ maintenance clause, since warranty claims on coil failures are routinely denied when the owner cannot produce proof of annual cleaning.

Signs Your Abatement Technologies Coil Cleaning Is Failing

- Weak airflow at registers despite a running blower. The coil has accumulated enough biofilm and dust matting that air cannot pass through the fins; in Houston’s 75%+ average humidity, this happens faster than in drier climates because moisture binds particulate into a sheet rather than loose dust.
- Ice formation on the evaporator coil housing. Restricted airflow drops the coil surface temperature below freezing, and the ice layer then insulates the coil further, creating a feedback loop that can crack the copper tubing if left running.
- Musty or sour odor when the system cycles on. Bacterial growth on a dirty coil produces volatile organic compounds; the smell is not “just dust” but active microbial colonization that standard filter changes will not reach.
- Short-cycling, where the unit turns on and off rapidly. The system reaches its pressure limit or temperature safety threshold prematurely because heat transfer across the coil is compromised, forcing the compressor to work harder and fail sooner.
- Water pooling below the air handler. A dirty coil sheds condensate unevenly, overwhelming the drain pan or causing it to overflow; in Houston’s older Meyerland and Timbergrove homes with original PVC drain lines, this often shows up as a ceiling stain before the owner checks the unit.

AfterReplacement Cost & What’s Included
| Service | Typical Range | What’s Included |
|---|---|---|
| Evaporator coil cleaning (single coil) | $340-$460 | Chemical foam application, low-pressure rinse, fin straightening, drain pan treatment, photo documentation |
| Condenser coil cleaning (outdoor unit) | $280-$380 | Biodegradable foaming cleaner, coil comb-out, refrigerant line inspection, electrical connection check |
| Dual-coil system (PAS series) | $480-$580 | Both coils, separate cleaning agents per manufacturer spec, full system pressure test |
| Coil coating restoration (if fins are corroded) | $120-$180 add-on | Hydrophilic coating reapplication, only where fin integrity allows |
The range depends on accessibility, not upselling. A coil in a tight attic with a scuttle hatch in Memorial takes longer than a basement utility room in Sugar Land, and we price that difference in writing before starting, per Haven Standard Clause 1. Every coil cleaning includes our Documented Photo Record of the coil condition before and after, delivered as part of the standard job record. The 365-Day Done Right Promise applies: if the coil shows recurring fouling due to our cleaning protocol, we return and correct it at no charge.
DIY or Call Us?

An owner can safely check three things: whether the filter is seated properly (a gap of even a quarter-inch bypasses filtration straight to the coil), whether the condensate drain line exits freely, and whether the outdoor condenser has visible debris like cottonwood seed or grass clippings on the exterior fins. These checks do not require tools beyond a flashlight and do not void warranty.
Where DIY goes wrong is the cleaning itself. Abatement Technologies coils use aluminum fins at 8-14 fins per inch, and a standard hardware-store brush or pressure washer folds them flat in seconds, permanently reducing airflow. The foaming agents matter too: alkaline cleaners on a UV-series coil strip the factory coating that prevents microbial adhesion, and the wrong pH is not visible until the coil fails prematurely. The refrigerant lines and electrical connections inside the air handler are live and pressurized; disturbing them without gauges and lockout training risks refrigerant release or contact with 240V terminals. We do not recommend owner-applied chemical cleaning on any Abatement Technologies unit. Call (346) 251-8919 and we will put the scope and price in writing before the truck rolls.
FAQs
In Houston’s climate, a properly maintained coil typically lasts 12-18 years, but we see premature failure at 7-9 years when annual cleaning is skipped and the hydrophilic coating degrades. Gulf Coast humidity accelerates galvanic corrosion where aluminum fins meet copper tubing, so the maintenance interval matters more here than in drier markets.

No. Once biofilm or corrosion has compromised fin integrity, cleaning cannot restore lost surface area; the only repair is coil replacement, which runs $1,800-$3,200 installed depending on refrigerant type and accessibility. Cleaning is preventive, not restorative, which is why we photograph the coil condition so owners can see whether they are maintaining an intact coil or delaying an inevitable replacement. Call (346) 251-8919 for an exact quote - estimates are free.
A single evaporator or condenser coil cleaning takes 90-120 minutes on-site, including setup, chemical dwell time, rinse, and system restart verification. Dual-coil PAS systems or units in restricted spaces add 30-45 minutes. We do not price by the hour; the written quote is flat regardless of time required. Call (346) 251-8919 for an exact quote - estimates are free.
We stock Abatement Technologies-compatible foaming cleaner, low-pH rinse, and fin comb sets on every truck, along with Guardsman aftermarket equivalents for owners who prefer them. For coil coating restoration, we match the specific Abatement Technologies spec from inventory; no ordering delay. Same-day scheduling is available when you call before noon. Call (346) 251-8919 for an exact quote - estimates are free.
CleanRun Duct Repair & Cleaning also stocks parts and performs coil cleaning for Lennox, Trane, and Carrier systems.
