Why Cardinal Air Duct Cleaning Is Selma’s Preferred HVAC Cleaning Company

We work in Selma every week. Our technicians know the housing stock here: the mid-2000s builds in Ashley Place, the older ranch-style homes closer to FM 1518, and the newer developments pushing toward Retama Parkway. That matters because a 2,100-square-foot Selma home with long flex-duct runs cleans differently than a compact San Antonio condo.

Omar Haddad runs our team, and he’s built the operation around one principle: you see exactly what we do and what it costs before we start. Every Selma booking follows The Relay Standard. You get a live trackable arrival time, a technician whose name you know before they knock, and a written price in hand before any equipment comes off the truck.

We’re part of the Relay Home Co. family, founded in 2005, and every job is covered by the 365-Day Done Right Promise. If the work isn’t right within a full year, we come back and correct it at no charge. That’s not a line on a flyer. It’s the standing rule on every booking, including yours in Selma.

AC Coil Cleaning in Selma

AC coil cleaning in Selma removes the packed dust and grime from your evaporator coil, the component that sits inside the air handler and does the actual cooling work. In Selma’s climate, coils collect a specific kind of residue: fine limestone dust from the Hill Country, mixed with humidity that bakes it into a paste. Left alone, that layer insulates the coil and forces your system to run longer to hit the same temperature.

Most Selma homes need evaporator coil cleaning every 2 to 3 years. Homes closer to the US-90/I-410 corridor, where truck traffic runs all day, often need it sooner. The coil sits in the dark and stays damp through our long cooling season, so everything it catches tends to stay. We clean it at the source. Our team pulls the access panel, applies a professional-grade coil cleaner, and rinses with a low-pressure wash that won’t bend the fins. The process restores full airflow and drops the load on the compressor.

Cost in Selma runs $150 – $300 for a standalone evaporator coil cleaning, depending on whether the coil is slab-style or A-frame and how much room the air handler cabinet gives us. If we’re already doing a HVAC Cleaning on the full system, the coil work is included in the per-system price, not added on as a separate line.

What a Dirty Coil Does to Your Selma Home

A coated evaporator coil cuts airflow and drives up runtime. That shows up on your CPS Energy bill during the hottest months when your system is already working hard. It also shortens compressor life, and compressor replacement is the most expensive repair any AC will ever need. We’d rather clean the coil every few years than sell you a new condenser in 2030.

Coil Treatment After Cleaning

After the coil is clean, we apply a Guardsman antimicrobial treatment that slows regrowth of the biofilm that thrives on wet coils in humid air. It’s not a permanent fix, but it keeps a freshly cleaned coil cleaner for longer in Selma’s climate. The treatment is optional, quoted up front, and never a surprise on the invoice.

AC Cleaning in Selma

AC cleaning in Selma covers the whole air side of the system: the return and supply ducts, the blower motor and wheel, the air handler cabinet, and the coil. You need it when your registers are gray with dust, when the system smells musty when it first kicks on, or when the house gets dusty again within a day or two of wiping surfaces. Those are signs the system is circulating dirt instead of moving it out.

In Selma, we frequently find a specific pattern in homes along the US-90 rail corridor: heavy carbon-laced dust from diesel trains and truck exhaust gets pulled into the return side and settles out in the first five feet of flex duct near the air handler. That’s exactly why our process starts at the source. We don’t just run a brush through the supply vents and call it done. We remove the blower assembly, clear the air handler cabinet, and only then move on to the duct runs.

Full AC cleaning in a typical Selma home runs $325 – $600. That’s a flat per-system price agreed before any work starts. No per-vent add-ons, no “we found mold so now it’s triple” games. We bring Rotobrush rotary agitation tools, Nikro HEPA-filtered negative-pressure extraction, and Abatement Technologies containment where needed so the loosened debris goes into the vacuum, not back into your living room.

Blower Motor and Air Handler Cleaning

The blower wheel is the part people never see but should. In Selma, our technicians regularly pull blower wheels coated in a gray felt of compacted dust, pet hair, and carbon particles. A dirty blower wheel moves 20 to 30 percent less air, and it throws the wheel out of balance, which eats bearings over time. We remove the wheel, clean it by hand, and photograph it before we put it back.

What You Get When We’re Done

Before-and-after photos of your own ducts, not stock images from someone else’s house. A digital invoice payable from your phone. And a 365-Day Done Right Promise: if anything isn’t right within a year, we return and fix it at no charge. That’s the standard for every Selma job, not a premium tier.

Trusted Brands We Service in Selma

We clean and maintain systems from every major HVAC manufacturer, and we keep common parts and filters in our trucks for Selma jobs. Whether your system uses a Honeywell filtration cabinet, an Aprilaire media filter, or a standard 1-inch filter at the return, we can service it the day we’re out. When you have a Guardsman coil treatment applied, we explain exactly what it does, how long it lasts, and what it costs before you agree to it. We’d rather you know the facts than buy something you don’t need.

Common HVAC Cleaning Problems We See in Selma Homes

• Rail carbon and road dust in the return side. Homes close to the US-90 rail line pull in more fine black particulate than homes in Converse or Live Oak. We see it in the return plenum and the first few feet of flex duct on nearly every Selma job.
• Collapsed flex duct near the air handler. In the Ashley Place neighborhood off Lookout Road, we cleaned a 14-year-old system where the return-side flex duct had collapsed at the air handler, starving airflow and baking the blower motor. We restored the run, pulled several pounds of carbon-laced dust out with Rotobrush agitation under negative pressure and HEPA filtration, and photographed everything before and after.
• Heavy pollen and oak debris from Selma’s tree cover. The mature oaks in the older neighborhoods around FM 1518 shed a lot of material that finds its way into outdoor condenser units and, eventually, into the indoor air stream.
• Flat-rate quotes that quietly became per-vent invoices. We see this enough that we built our pricing policy around it. You get one flat price per system, in writing, before any work starts. That price does not change when the technician walks through the door.
