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.

AfterHoneywell HVAC Cleaning in San Antonio: What to Know First
We provide independent Honeywell HVAC cleaning in San Antonio for air handlers, evaporator coils, blower assemblies, and condenser units, with most jobs completed in a single scheduled visit. A typical Honeywell system cleaning runs $280-$520 depending on access and contamination level, and we deliver that number in writing before any panel comes off. This page is for San Antonio homeowners who own a Honeywell system and need to know whether their unit can be cleaned safely, what it will actually cost, and whether the company they hire understands the difference between a Honeywell HZ432 TrueZONE panel and a generic control board. Call (726) 600-7155 for a free written estimate.
How Honeywell Products Fail - and How We Fix Them
- Prestige IAQ and VisionPRO IAQ thermostats lose calibration after coil contamination. These units rely on remote sensors that drift when airflow patterns change due to debris buildup on the evaporator. We clean the coil, verify sensor placement against Honeywell’s 62-0236 installation manual, and re-test humidity differential before we leave.
- TrueZONE HZ432 and HZ322 panels suffer relay failure when blower motors run dirty. The panel sends signals a struggling blower can’t execute, burning out relays that cost $180-$240 to replace. We clean the blower wheel and housing first, then load-test the amp draw against the motor nameplate before declaring the zone panel healthy.
- Media air cleaners (F100, F200, F300) bypass unseated filters and coat the coil downstream. Homeowners in Alamo Heights and Terrell Hills often find these filters bowed or improperly seated after DIY changes, sending unfiltered air straight to the coil. We photograph the bypass path, clean the coil, and reseat the media with the pressure-drop gauge reading documented.
- Evaporator coils in Honeywell matched systems with aluminum fins corrode faster in San Antonio’s hard water and high humidity. The calcium-heavy municipal supply leaves scale that traps biological growth. We apply a foaming cleaner compatible with aluminum microchannel coils, never the acid-based products that void the warranty and pit the fins.
- Communicating systems (ComfortNet, RedLINK) throw false error codes when coil pressure drops from restricted airflow. A dirty coil reads like a refrigerant fault to the board. We clean first, measure static pressure across the coil, and only then interpret any remaining codes through Honeywell’s service software.
Our Honeywell HVAC Cleaning Process
- 1
Written price delivered on arrival. Haven Standard Clause 1: we inspect access points, identify your Honeywell model and serial, and hand you a written scope with a fixed price before the first tool comes out.
- 2
Photo documentation of internal condition. The camera goes in first. Then we talk. Tomas Reyes started this practice in 2013, and we still deliver before-and-after images of every component we touch.
- 3
Component-specific cleaning protocol. Evaporator coils get foaming cleaner rated for aluminum microchannel construction. Blower wheels are removed and cleaned out of the housing to avoid pushing debris into the motor. Condenser coils are straightened with fin combs matched to Honeywell’s fin density.
- 4
OEM-versus-aftermarket parts decision. When a part needs replacement, we show you the Honeywell OEM option and the quality aftermarket equivalent, with warranty implications for each, and you choose. No default to the highest-margin part.
- 5
Operational test and pressure verification. We run the system through all stages, measure temperature split and static pressure, and verify that any Honeywell zone panel or communicating thermostat reads normal operation.
- 6
Documented Photo Record and 365-Day Done Right Promise delivered. Your job file includes all images, the written scope, and the warranty document. If something isn’t right, we make it right. That’s in writing, not spoken over a closing handshake.
BeforeAfterWhat Honeywell HVAC Cleaning Costs in San Antonio
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning | $280-$380 | Access (horizontal attic vs. vertical closet), fin corrosion severity, refrigerant line obstruction |
| Blower assembly cleaning | $240-$340 | Wheel removal required, motor bearing condition, housing contamination depth |
| Condenser coil cleaning | $180-$280 | Fouling type (grass clippings vs. grease/oil from nearby exhaust), fin restoration needed |
| Full air handler cleaning (coil + blower + housing) | $420-$520 | System size (2-5 ton), secondary drain pan condition, insulation replacement needed |
| Heat exchanger cleaning / inspection | $200-$320 | Access panel configuration, camera inspection depth, combustion analysis required |
These are whole-system prices, not per-vent or per-coil-face teaser rates. Every estimate is free, every price is fixed before work starts, and every job includes the Documented Photo Record. Call (726) 600-7155 for your written estimate.
Why San Antonio Homeowners Call CleanRun Air Duct Cleaning San Antonio for Honeywell Work
We’ve cleaned Honeywell systems in San Antonio since 2013, from the original 1980s round flex installations in Castle Hills to the communicating variable-speed systems going into new builds near Boerne. Our technicians train on Honeywell’s control logic, not just generic HVAC principles, because a RedLINK thermostat troubleshooting a dirty coil behaves differently than a Lennox iComfort or Carrier Infinity board handling the same fault.
The 365-Day Done Right Promise applies to every Honeywell job we touch. The Documented Photo Record shows you what was actually inside your unit, not what someone claims they cleaned. And if you have a written estimate from another San Antonio contractor for the same Honeywell work, we’ll deliver a free second opinion in writing under Haven Standard Clause 5.
We also service Lennox, Trane, and Carrier systems, which matters when your Honeywell controls are integrated into a mixed-manufacturer setup common in San Antonio retrofits.
FAQs
No, professional cleaning does not void your Honeywell warranty, but using non-approved chemicals or improper fin-comb techniques can. We use foaming cleaners rated for aluminum microchannel coils and document our methods so any future warranty claim has a service record attached. Call (726) 600-7155 if you need a copy of our cleaning protocol for your warranty file.
If your system is under 12 years old and the coil or blower is simply contaminated, cleaning almost always restores performance. We replace components only when we can show you measurable failure: a blower drawing 30% over nameplate amps, a coil with fin corrosion exposing the copper tube, or a heat exchanger with visible breach. The camera goes in first. Then we talk. Call (726) 600-7155 for an honest assessment.
For control boards and communicating thermostats, OEM parts usually prevent compatibility headaches. For filters, contactors, and capacitors, quality aftermarket equivalents from recognized manufacturers perform identically at lower cost. We show you both options with installed prices and warranty terms before you decide. Call (726) 600-7155 to discuss your specific Honeywell model.
Most residential cleanings take 2.5 to 4 hours, depending on system location and contamination level. We schedule a specific arrival window, not an all-day wait, and we don’t leave until the operational test confirms normal performance. Call (726) 600-7155 to book a slot that works for your schedule.
Yes, and we pay specific attention to the F300E electronic air cleaner’s power head and cell alignment, which can arc if misaligned after service. We remove, clean, and reinstall the cells with the airflow arrow verified against the duct direction, then test for ozone production within manufacturer spec. Call (726) 600-7155 to schedule.
