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.

AfterFast, Reliable HVAC Cleaning Across San Antonio
HVAC cleaning in San Antonio typically costs $285-$640 for a full system, and the most urgent window here runs late February through March, when cedar pollen has finished loading your ductwork and before summer heat forces your AC to run nonstop. Our crews work on slab-on-grade, attic-ducted homes daily, from older buildouts off Loop 1604 to the pre-war neighborhoods closer to downtown.
CleanRun Air Duct Cleaning serves San Antonio directly, with dispatch coordinated from our local San Antonio office. Every job starts with a written price before any work begins, and every client receives a documented photo record of their ductwork, inside and out. Call (806) 606-6902 to get a free estimate in writing.
Why CleanRun Air Duct Cleaning Is San Antonio’s Preferred HVAC Cleaning Company
San Antonio’s housing stock is uncommonly hard on duct systems. Homes built along the US 281 and Loop 1604 corridors from the 1970s through the 2000s often sit on slab foundations with flex duct runs through attics that bake at 150°F or more every summer. We know what that heat does to duct material, and we know what a failed joint looks like on a camera feed. That local knowledge changes the outcome of a cleaning job.
Since 2013, we have completed 52,000+ homes, every one with a written price before the crew arrived and a photo record when the crew left. Our San Antonio customers tell us they value the evidence over the sales talk: the before photo of a return plenum caked with caliche dust, the after photo of the same plenum, clean metal. Tomas Reyes, our owner, set that standard on day one and it has never changed.
Our technicians are background-checked, uniformed, and identified by name before they step into your home. We answer the phone live at (806) 606-6902, day or night, and every job carries the 365-Day Done Right Promise, in writing.
Our HVAC Cleaning Services in San Antonio
Every system gets cleaned as a system, not as a set of disconnected parts. Here is what that looks like in practice for the four most common service calls we handle across San Antonio.
Evaporator Coil Cleaning
On homes with long cooling seasons, the evaporator coil becomes the primary surface where condensation meets airborne debris. In San Antonio, that debris includes cedar pollen, caliche dust, and mold spores, and it forms a wet, packed film across the coil face. We remove that film using professional-grade extraction equipment and coil-safe cleaning agents that break down the biological and mineral layers without eating into the coil material. This is the single biggest efficiency repair we do in San Antonio, and it often accounts for several hundred dollars of unnecessary energy cost every year.
Air Handler Cleaning
The air handler is the heart of a forced-air system and the most common place we find the “gritty gray layer” San Antonio homeowners ask about. That layer, usually a blend of caliche particulate and pollen bonded by condensation, coats the blower wheel, housing, and internal casing far more aggressively than typical household dust, and it also degrades by reducing airflow and putting strain on the motor. We clean and inspect the entire air handler, checking for bearing wear and belt tension issues, and note these in the after-photo record.
Condenser Cleaning
The outdoor condenser unit on a San Antonio home works hard nearly year-round, but it also lives in a punishing environment: full sun, construction dust, grass clippings, and the fine calcium-carbonate powder that drifts from every bare caliche lot in the northern and western suburbs. Our crews deep-clean condenser coils, clear debris from the unit housing, and check refrigerant line insulation. A condenser caked in caliche dust rejects heat poorly, which means your system runs longer, costs more, and ages faster than it should.
Coil Treatment
After cleaning coils, we apply a professional-grade coil treatment to slow future biological growth, especially on systems in high-humidity areas of the home, such as laundry rooms, or on units that serve homes with a history of condensation problems around the air handler. For San Antonio’s near year-round cooling season, we strongly recommend coil treatment as standard practice after cleaning, not as an upsell. It extends the clean period measurably, and we include it in our written quote, not as a surprise on the invoice.

BeforeAfterTrusted Brands We Service in San Antonio
We work on all residential HVAC systems, and our technicians carry parts and cleaning supplies sized for the brands most common in San Antonio homes. That includes Honeywell and Aprilaire filtration and media systems widely installed in new construction along Cibolo and Schertz, plus conventional split systems and packaged rooftop units in older neighborhoods like Mahncke Park. Because we stock these locally, our San Antonio customers aren’t waiting on a parts shipment to finish a standard cleaning or coil repair, and the Rotobrush and Nikro extraction equipment we bring onsite is the same professional-grade gear used in commercial settings, maintained and ready for the volume of work we see here in San Antonio.
Common HVAC Cleaning Problems We See in San Antonio Homes
- Return plenums loaded with compacted caliche dust. The fine gray powder that covers everything north and west of San Antonio gets pulled into HVAC intakes and settles in the return plenum, where it packs hard. In homes near 1604, we’ve seen airflow restricted by up to 30% from this layer alone, which we photograph and fix.
- Cedar pollen bonded to duct walls. December through February, Ashe juniper pollen coats the inside of ducts, then summer condensation locks it on. A low-agitation cleaning that only brushes the inner duct surface doesn’t break that bond, so the pollen re-releases into the living space within weeks.
- Sagged or crushed flex ducts in older attics. Many homes built between 1980 and 2000 still have original flex duct runs, now brittle and misshapen from years of 150° attic heat. Cleaning does not repair a crushed duct, but our camera inspection after cleaning will show it, so you know what is really causing that weak airflow.
- Decade-old buildup in rental homes near JBSA-Lackland. In zip codes like 78245 and 78227, military tenant families rotate through on 2-3 year PCS orders, and maintenance can fall through the cracks. We have opened systems in this area that had not been cleaned in 10+ years, with debris depths that required multiple extraction passes.
Pricing for HVAC Cleaning in San Antonio, TX
A whole-system HVAC cleaning in the San Antonio market generally runs between $285 for a smaller home with accessible ductwork and $640 for a larger, multi-zone home with additional components like a whole-house media filter or dual returns. Air handler cleaning alone typically lands between $150 and $260. Evaporator coil cleaning is usually $130 to $240, while a full condenser coil clean falls between $95 and $185. Coil treatment after cleaning ranges from $85 for a single coil to $180 for both coils on a dual-zone system.
What changes the price? The number of returns and registers, the accessibility of the air handler (attic systems take longer than closet systems), and how many years of buildup the system has accumulated. We quote a single flat price per system, in writing, before any work starts. That is Haven Standard Clause 1: written price before a single panel comes off.

FAQs - HVAC Cleaning in San Antonio
Yes. Cedar pollen is carried in through door gaps, entryways, attached garages, and on clothing, and your HVAC return pulls it straight into the duct system. Once inside, it settles on humid coil surfaces during summer and bonds there, then recirculates through the home long after the cedar season ends. Call (806) 606-6902 if you want us to inspect what’s in your ductwork with a camera before committing to a cleaning.
In San Antonio’s climate, with 9-10 months of cooling and a heavy winter pollen load, we recommend a full HVAC cleaning every 2 to 4 years. Homes with high-occupancy, pets, or newer construction activity nearby may warrant it annually. That’s notably more frequent than the national 3-5 year average, because the biological and mineral debris accumulates faster here.
That’s almost always caliche dust, the fine calcium-carbonate particulate from San Antonio’s alkaline soil, which has been pulled in through your return and is now caked inside the plenum. It compacts into a hard layer that restricts airflow, and a standard vacuum won’t remove it. We document that layer with a photo before extraction and show you the after image once the plenum is clean.
Cleaning removes debris from the inside, but it cannot repair a crushed, sagged, or disconnected flex run. In homes from the 1980s and 1990s, especially along the Loop 1604 and US 281 corridors, those original flex ducts are often brittle and misshapen. Our camera inspection after cleaning identifies those failures, and we can seal and re-support the runs where possible, or quote a replacement if needed.
Because military tenant families move on 2-3 year PCS orders, rental properties near JBSA-Lackland in zip codes like 78245, 78227, and 78250 often skip regular HVAC maintenance entirely, so systems accumulate a decade or more of cedar pollen, caliche dust, and mold from summer condensation. We have opened systems in this area that had never been cleaned, and the before-and-after photo record tells the story better than any sales pitch could.
