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 Alvin
HVAC cleaning in Alvin means dealing with what the Gulf Coast humidity leaves behind: a stubborn film that coats your blower wheel and evaporator coil, not just the dust you can see on a vent cover. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family (founded 2005), and we approach every Alvin job with one flat price per system agreed before work starts. No per-vent pricing. No surprises at the door. If your air handler is working harder than it should, call (737) 727-2314 and we’ll give you a straight answer, a written quote, and a time that works.
Why Cardinal Air Duct Cleaning Is Alvin’s Preferred HVAC Cleaning Company
Alvin homeowners call us because we treat the whole system, not just the visible ductwork. That matters here. Homes off Highway 6 and along Gordon Street were mostly built for a climate that punishes evaporator coils with constant moisture. When the blower wheel gets coated, airflow drops. When the coil gets filmed over, the system runs longer to hit the same temperature. We clean the air handler, blower, coil, and duct runs as one job because that’s how the system actually fails.
Every appointment includes a written price before work begins, background-checked technicians in uniform, and a live trackable arrival time through The Relay Standard. You’ll know your tech’s name before they knock. Omar Haddad leads our team, and the standard he sets is simple: show the customer their own ducts before and after, and stand behind the work for 365 days. If something isn’t right within that year, we come back and make it right at no charge.
AC Cleaning in Alvin
AC cleaning in Alvin is the service most homes here actually need, and it goes far beyond brushing out a few supply vents. The real work happens inside the air handler. In Alvin’s humidity, the blower motor and housing collect a gray, lint-heavy film that reduces airflow and makes the system run longer. We remove the blower, clean the wheel and housing, clear the drain pan, and treat the coil. Most standard AC cleanings for a typical Alvin home run $350 to $650 depending on system size and accessibility.
Blower and Air Handler Work
The blower is what moves conditioned air through your ducts. When it’s coated, airflow drops even if your filter is clean. We pull it, clean it, and check the motor amp draw after reassembly. That’s the kind of check a vent-only cleaning never does.
Drain Pan and Condensate Line
Alvin’s summer humidity means your coil condenses constantly. A clogged drain pan or line leads to water damage and microbial growth. We clear it, treat it, and verify it drains before we leave.
Evaporator Coil Cleaning in Alvin
Evaporator coil cleaning in Alvin is the single highest-impact step for AC efficiency. This coil sits inside your air handler and absorbs heat from your home’s air. After one coastal summer, it’s typically coated with a damp, insulating film of lint, pollen, and dust. That film slows heat transfer and forces your compressor to run longer. Cleaning it properly requires removing the access panel, applying a professional-grade coil treatment, and rinsing with controlled water pressure. Evaporator coil cleaning in Alvin typically runs $200 to $450 as part of a full system cleaning.
When the Coil Film Gets Bad
If your system runs constantly in July and the house still feels muggy, a filmed coil is often the cause. We see it in homes throughout Alvin, especially on older systems near the coast. Cleaning restores capacity without replacing a single part.
Coil Treatment, Not Just Rinsing
We use a professional coil treatment that breaks down the bonded film, not just a water rinse from a garden sprayer. After treatment, we document the coil with photos so you can see the difference. You should never have to take a technician’s word for what happened inside your air handler.
Trusted Brands We Service in Alvin
We work on all major residential HVAC brands found in Alvin homes: Carrier, Trane, Lennox, Goodman, Rheem, and American Standard. Our trucks carry common filters, drain line treatments, and coil cleaning supplies sized for the systems we see most around town, so we’re not running back to a supply house mid-job. We also run professional-grade cleaning equipment: Rotobrush rotary brush systems for duct agitation, Nikro HEPA-rated vacuums for negative-pressure extraction, and Abatement Technologies containment units when needed. This is not a truck-mounted shop vacuum. When we open your air handler, the debris goes into our vacuum, not back into your living room.
Common HVAC Cleaning Problems We See in Alvin Homes
- Humidity-driven coil film. Alvin’s Gulf air keeps your evaporator coil damp for months. That film reduces efficiency and makes the system run longer than it should.
- Attic-mounted air handlers pulling insulation dust. Many Alvin homes, especially older ones off South Gordon and near Mustang Bayou, have air handlers in the attic. Return ducts with small gaps pull in insulation particles that coat the blower and clog the coil.
- Blower wheel buildup from pet hair and carpet lint. The humid air acts like a magnet, gluing hair and lint to the blower wheel. A blower that heavy draws more amps and moves less air.
- Per-vent pricing that skips the air handler. We regularly see Alvin homeowners who paid for a vent-only cleaning and were left with the same problem because the blower, coil, and drain pan were never touched. That’s why we quote per system, not per vent.

FAQs About HVAC Cleaning in Alvin
We charge by the system, not by the vent. Per-vent pricing misses the real labor in the air handler, blower motor, and evaporator coil, which is where Alvin’s humidity does the most damage. You get one written price for the entire job before we start, and that price does not change at the door. Call (737) 727-2314 for an exact quote.
Every 3 to 5 years is honest for most Alvin homes. Homes with pets, new carpet, recent construction, or easy access to outdoor dust near fields may need it every 2 to 3 years. If your filter has been doing its job and airflow is strong, you may not need cleaning at all. We’ll tell you if we don’t think you need the service.
Yes. Every job includes before-and-after photo documentation of your own supply and return ducts via The Relay Standard. You see what we saw. If a section was cleaned, you have proof. If a section was already clean and we skipped it, you’ll see that too.
We run Rotobrush rotary brush systems for agitation, Nikro HEPA-rated vacuums for negative-pressure extraction, and Abatement Technologies containment units when needed. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. We also carry Guardsman and Aprilaire filtration products for homeowners who want upgraded air quality.
We do not promise same-day service, and we won’t rush a job that deserves care. What we do is answer the phone live, 24/7, and usually schedule Alvin appointments within a few business days. You’ll get a written price before scheduling and a live trackable arrival window on the day of the job. Call (737) 727-2314 and we’ll get you on the calendar.
