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.
Honeywell Air Quality & Sanitizing in San Antonio: What to Know First
CleanRun provides independent Honeywell air quality and sanitizing services throughout San Antonio, with most scheduled jobs completed in a single visit and written pricing delivered before any equipment is touched. A typical whole-system sanitizing job with photo documentation runs between $380 and $720 depending on system size and whether UV light installation is included. We’re not affiliated with Honeywell - we work on their equipment as an independent service provider, which means our recommendations are based on what we find in your ductwork, not on a manufacturer’s script.
This page is for San Antonio homeowners running Honeywell whole-home air purifiers, UV treatment systems, or integrated media filters who’ve noticed persistent odors, elevated allergy symptoms, or visible microbial growth at registers. If you’re researching before calling, you’re the customer we built this for. Call (726) 600-7155 and we’ll put a written estimate in your hands.
How Honeywell Products Fail - and How We Fix Them
- UV2400U and UV100 series lamp degradation. The 16-inch germicidal lamps in these whole-home UV systems lose output steadily after 9,000 hours, but many San Antonio homeowners don’t realize the lamp is dead until mold appears on the evaporator coil. We measure actual UV-C output with a radiometer, not just lamp hours, and replace with spec-matched bulbs that restore the 253.7 nanometer wavelength Honeywell designed for. The plenum - the main distribution box where all duct runs connect - is where we most often find the lamp has been running dim for two seasons.
- F100 and F200 media air cleaner bypass leakage. The cabinet seals on these bypass-style electronic cleaners compress over time, especially in the heat-cycling climate of San Antonio where expansion and contraction are constant. We find unfiltered air slipping past gaskets that have hardened to plastic. Our fix: pull the cabinet, photograph the gap, and reinstall with fresh compression seals - not duct tape, not caulk, but OEM-spec gasket material that restores the rated MERV efficiency.
- TrueCLEAN FH8000 ozone plate fouling. The electrostatic precipitator plates in this series attract fine Texas Hill Country dust that becomes conductive when humidity spikes above 65%, which it does regularly in San Antonio from May through October. The plates arc, the power supply faults, and the homeowner smells ozone. We remove and wash plates in a non-conductive cleaning solution, test each cell for micro-cracks that cause the arcing, and replace only the cells that fail - not the whole stack.
- DR90 and DR120 dehumidifier drain pan biofilm. These whole-home dehumidifiers, common in Stone Oak and Alamo Ranch builds from 2016 to 2022, develop thick bacterial mats in the condensate pan when condensate pumps cycle incompletely. The pan looks clean from above; the camera scope shows black slime at the low point. We disassemble, photograph the biofilm, treat with an EPA-registered sanitizer, and verify complete drainage before reassembly.
- HEPA bypass installation errors on new construction. We’ve documented six installs in the past year where the HEPA unit was ducted with flex that collapsed at the first elbow, creating a pressure drop that renders the filtration meaningless. The homeowner thinks the HEPA is underperforming; what’s actually happening is that most of the return air is bypassing it entirely. We replace the collapsed flex with rigid duct where code allows, or with supported flex at proper bend radius, and verify static pressure across the unit.
Our Honeywell Air Quality & Sanitizing Process

- 1
Scope and photograph before quoting. We run a camera scope through every accessible duct run - the individual branch lines from plenum to register - and photograph what we find. The camera goes in first. Then we talk.
- 2
Written price under Haven Standard Clause 1. You receive a single flat price for the complete job, not per-vent arithmetic, before any panel comes off. No exceptions.
- 3
OEM or verified-equivalent parts selection. For Honeywell UV lamps and media filters, we stock OEM where the warranty or performance spec demands it. For seals, hardware, and consumables, we use quality aftermarket that meets or exceeds manufacturer ratings - and we tell you which is which before you agree.
- 4
Negative-pressure extraction and contact sanitizing. We connect a Nikro or Abatement Technologies negative-air machine to your plenum, which pulls contaminants out under controlled vacuum while we apply sanitizer directly to contaminated surfaces. This is not a fogger tossed into a register; it’s targeted treatment with the debris actively being removed.
- 5
Post-work photography and pressure test. Every duct run is photographed after cleaning. Static pressure and airflow are measured at the air handler. You receive the photo record and the written test results as standard deliverables.
- 6
365-Day Done Right Promise activation. The written guarantee goes into your job record. If anything we treated returns within a year, we make it right - not as a favor, but as a documented obligation.

Why San Antonio Homeowners Call CleanRun Air Duct Cleaning San Antonio for Honeywell Work

We’ve been in San Antonio since 2013, and the Honeywell equipment we see most often - the F100s in Alamo Ranch, the UV100s in Stone Oak tract homes, the DR90s in newer Helotes builds - follows predictable patterns that only show up after you’ve documented a few thousand systems. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier air quality equipment, which matters when your home has mixed-brand components or when we’re called in after another contractor’s incomplete job.
Every visit produces a Documented Photo Record of every duct run, before and after. The 365-Day Done Right Promise is written on every invoice, not just stated in marketing copy. And if you have a written estimate from another company, we provide a Free Second Opinion at no cost - our number next to theirs, both in writing.
FAQs
No. As an independent Honeywell service provider, we use manufacturer-specified parts and practices that preserve warranty coverage on the equipment itself. The warranty does not require you to use Honeywell-authorized dealers for maintenance or repair.
We show you. The photo record includes before-and-after images of the same duct run locations, and we measure airborne particulate with a laser particle counter at the supply registers post-treatment. You’ll have both in your job file. If you want third-party lab verification of mold or bacteria levels, we can coordinate that at additional cost.
Replace the power supply if it’s more than seven years old - we’ve found that aged ballasts deliver inconsistent voltage that degrades new lamps within a season. If the cabinet is rusted or the lamp socket is corroded from condensate exposure, replacement is usually more economical than chasing intermittent failures. We’ll photograph the damage and give you both options in writing.
The $79 coupon model relies on upselling once the truck is in your driveway - per-vent charges, “surprise” mold findings, equipment you didn’t request. Our price is flat, written, and complete before we start. We’ve documented competitors’ work where the “sanitizing” was a handheld fogger run for ninety seconds and the “UV install” was a hardware-store bulb zip-tied to the duct wall. The photo record is how we prove the difference.
UV lamps annually - the output degrades before they go dark. Media filters per the pressure-drop indicator, typically every 6-12 months in our dust-heavy climate. Whole-system sanitizing when you see visible growth, smell persistent mustiness, or after any water intrusion event. For most San Antonio homes with Honeywell equipment, a professional inspection every two years catches the problems before they become health issues.
