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 Somerset
HVAC cleaning in Somerset, TX means dealing with a specific kind of dirt: the fine caliche grit that blows up from the Atascosa County line and settles into return ducts, evaporator coils, and blower wheels. We’ve worked enough homes off Somerset Road and around the Junior High to know what that dust does to a system over three or four South Texas summers. A full HVAC cleaning typically runs $450 – $850 for a standard Somerset home, and we hand you a written price before any work starts, not after. Call (737) 727-2314 and you’ll get a live person, not a voicemail tree.
Why Cardinal Air Duct Cleaning Is Somerset’s Preferred HVAC Cleaning Company
Somerset homeowners don’t have time for vague estimates or a tech who shows up with a shop vac and a coupon book. That’s why our process is built around one flat price per system, agreed before we touch a single register, and backed by the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. No fine print, no partial coverage.
Every tech is background-checked and arrives in uniform. You’ll know the tech’s name before they open the door. The equipment is professional-grade: Rotobrush rotary brush systems for mechanical agitation, Nikro HEPA-rated vacuums for negative-pressure extraction, and Abatement Technologies containment units where the job calls for it. This isn’t a truck with a hose. It’s a full source-removal setup.
We coordinate scheduling from our San Antonio office, but crews serve Somerset locally, and our phone is answered by a live person around the clock. When you book, you get The Relay Standard: a live trackable arrival window, before-and-after photos of your own ducts, and a digital invoice payable by link. The full scope of HVAC Cleaning work we do is documented, photographed, and priced before the first vent is opened.
Evaporator Coil Cleaning in Somerset
Evaporator coil cleaning in Somerset is the single highest-impact part of most HVAC cleanings we do here, because the same caliche dust that coats the outside of your condenser also lines the indoor coil where your air actually cools. A coil caked in mineral grit loses heat transfer fast, which means longer run times, warmer supply air, and a compressor that works harder than it should. In Somerset, we regularly see coils with a dust-and-grit paste thick enough to block light through the fins. A standalone evaporator coil cleaning runs $175 – $350 depending on access and buildup.
What Coil Cleaning Includes
We remove the access panel, inspect the coil with a camera, and apply a non-acidic foaming cleaner that loosens the caliche without etching the aluminum fins. Then we rinse and extract with negative pressure so the loosened material goes straight into the HEPA vacuum rather than down into the drain pan or back into the air handler.
When Somerset Homeowners Need It
If your supply air feels weak or your AC runs constantly on 100-degree afternoons, the coil is usually part of the answer. Homes with pets, open windows, or a gravel driveway off Somerset Road tend to need coil attention more often. We’ll show you the after-photo so you can see the difference, not just take our word for it.
AC Duct Cleaning in Somerset
AC duct cleaning in Somerset deals with a different load than what you’d find in San Antonio’s inner loop. The bulk of what we pull from ducts here is fine mineral grit, not pet dander and carpet fiber. That means the cleaning approach matters: light brushing alone won’t dislodge caliche that’s packed into the bottom of return drops. A full AC duct cleaning in Somerset runs $350 – $650 for a typical single-story home, and we quote it as one flat price per system, never per vent.
Negative-Pressure Extraction, Explained
We run agitation tools through the supply and return ducts to break the grit loose, then pull it out with a HEPA-filtered negative-pressure vacuum. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. In homes off Calle Sombra and along Somerset Road, the amount of sandy material we remove from return ducts is consistently higher than what we see in Helotes or Converse.
What We Photograph
Before we start and after we finish, we run a camera down the main trunk and photograph the same sections. You get those images. If a section doesn’t come clean, you’ll see it, and we’ll address it under the 365-Day Done Right Promise rather than hiding behind a blurry photo.
Trusted Brands We Service in Somerset
We service and maintain whatever equipment is already in your Somerset home: Trane, Carrier, Lennox, Goodman, Rheem, and the rest. The cleaning tools we use are professional-grade, including Rotobrush brush systems and Aprilaire filtration products for post-cleaning air quality. If your system needs a new filter media or a Guardsman filter replacement, we stock common sizes on the truck so turnaround in Somerset is faster than waiting on a parts counter across town.
Common HVAC Cleaning Problems We See in Somerset Homes
- Caliche-packed return ducts. Homes on the southern edge of Bexar County pull in a lot of fine mineral dust, which settles hard in return drops. Light vacuuming without agitation won’t get it out; it needs mechanical brushing plus negative pressure.
- Coated evaporator coils. The same dust that lines the ducts also gets drawn through the filter and into the coil. We see this on nearly every Somerset home that’s gone more than three years without coil service.
- Collapsed or kinked flex runs. On a Calle Sombra job near Somerset Junior High, our tech ran a camera inspection down the main trunk and found a collapsed flexible run off the air handler that was starving two bedrooms of airflow – we pulled the section, ran agitation tools and negative pressure on the rest of the supply and return ducts, and the static pressure at the blower motor dropped back into range. We photographed the before-and-after of that same trunk run and left the images with the homeowner.
- Over-filtering with the wrong media. A lot of Somerset homes run high-MERV filters without a blower sized for the static pressure. That’s fine for air quality, but it loads the coil faster. A newer build with a MERV 11 filter may need coil attention more than a full duct cleaning, and we’ll tell you that straight instead of selling a service you don’t need.
Pricing for HVAC Cleaning in Somerset, TX
Our pricing in Somerset is one flat price per system, given to you in writing before work starts. A full HVAC cleaning (ducts plus evaporator coil plus blower) runs $450 – $850 for a typical home, depending on square footage, number of systems, and how much buildup is present. A standalone evaporator coil cleaning runs $175 – $350. AC duct cleaning alone runs $350 – $650. We never quote per vent, because that’s how a house with 14 registers gets padded while the coil and air handler go untouched. You’ll get the exact number before we open the first access panel. Call (737) 727-2314 for a free estimate, and we’ll send it in writing.

FAQs About HVAC Cleaning in Somerset
Most Somerset homes need full duct cleaning every 3 – 5 years, but homes with gravel driveways, open windows, or active construction nearby often need it sooner. The caliche dust that blows in from the Atascosa County line loads ducts faster than typical household dust. If you’re not sure, we’ll run a camera inspection and show you what’s actually in there before recommending anything. Call (737) 727-2314 and we’ll schedule a look.
One flat price per system. Always. We quote the full system, including ducts, coil, and blower, as a single written number before any work starts. Per-vent pricing is how a house with 14 registers gets a quote that pads the job while the coil and air handler sit untouched. We don’t do that.
Yes. Every job includes camera inspection before we start and after we finish, with photos of the same sections so you can compare them directly. The images are yours to keep. If a section doesn’t come clean, you’ll see it, and we’ll address it under the 365-Day Done Right Promise.
