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 Leander: What to Know First
We provide independent Honeywell air quality and sanitizing services in Leander with written pricing delivered before any work begins, typically completing most jobs in a single visit. Whole-system Honeywell sanitizing runs $340-$680 for most Leander homes, depending on system size and whether UV light installation or mold treatment is needed. Every job ends with a documented photo record of every duct run, delivered to you as a standard deliverable, not an extra.
This page is for Leander homeowners running Honeywell F100, F200, or F300 electronic air cleaners, whole-house dehumidifiers tied to Honeywell zoning systems, or any Honeywell-integrated HVAC who need actual sanitizing work, not a filter swap and a handshake. If your Honeywell system was installed between 2015 and 2022 in a Leander new build, there’s a decent chance the original contractor never sealed the ductwork properly, and the cedar pollen and construction debris have been compounding ever since. Call us at (737) 252-1285 for a free estimate with written pricing before we touch anything.
How Honeywell Products Fail - and How We Fix Them
- F100 Media Air Cleaner bypass leaks. The F100 series relies on a tight seal between the media cabinet and the ductwork. In Leander’s expanding neighborhoods like Crystal Falls and Travisso, we’ve found dozens installed with gaps at the plenum connection - the large distribution box where air mixes before entering the duct runs. Pollen and attic dust bypass the filter entirely, loading the evaporator coil with debris. We reseat the cabinet, seal with mastic, and photograph the pressure differential before and after.
- F200 Electronic Air Cleaner cell corrosion. The ionizing wires and collector cells in the F200 degrade faster in Central Texas humidity, especially when the cells aren’t washed quarterly. Corroded cells draw high voltage but produce almost no ionization; the “clean” light stays on, but the unit isn’t cleaning anything. We test output with a field meter, replace cells with Honeywell OEM or verified aftermarket equivalents, and show you the microamp reading on screen.
- F300E1019 UV system lamp degradation. The F300’s UV-C lamp loses effective output after roughly 9,000 hours - about 12 months of continuous operation - but the indicator LED often stays green. We measure actual UV intensity with a radiometer; if it’s below 40 microwatts per square centimeter at the coil surface, the lamp is decorative. We replace with Honeywell-compatible UV lamps and document the new reading in your job record.
- TrueDRY dehumidifier drain pan biofilm. Honeywell TrueDRY units mounted in Leander attics develop bacterial sludge in the condensate pan when drain lines sag or trap improperly. The musty smell isn’t “Texas humidity” - it’s active microbial growth being distributed through every register. We disassemble the pan, treat with EPA-registered sanitizer, correct the drain pitch, and photograph the pan before and after treatment.
- Zone board damper seal failure. Honeywell zone control systems in larger Leander homes depend on motorized dampers that close tightly when a zone calls off. The rubber seals harden after 5-7 years, leaking conditioned air into unused zones and creating pressure imbalances that draw attic air through ceiling penetrations. We pressure-test each zone, replace seals with Honeywell-compatible EPDM, and verify with a manometer - the pressure gauge that measures air resistance in inches of water column.
Our Honeywell Air Quality & Sanitizing Process

- 1
Inspection with camera and written scope. We feed a borescope into every accessible duct run, starting at the plenum - the central air distribution chamber - and document what we find. Tomas Reyes pulls the inspection camera out before quoting anything; if it doesn’t show up on screen, we don’t charge for it. Show the photo first. Then talk about what comes next.
- 2
Written price delivered before work begins. Haven Standard Clause 1: the price is fixed per system, not per vent, and you sign off before we remove a single panel. No “call for a quote” - the quote is in your hand.
- 3
Negative-pressure extraction and mechanical agitation. We use Rotobrush or Nikro contact-vacuum systems - brushes that physically scrub duct walls while a vacuum maintains negative pressure, so debris doesn’t escape into your living space.
- 4
Honeywell-specific component service. For electronic air cleaners, we remove and clean cells; for UV systems, we replace lamps and measure output; for dehumidifiers, we treat drain pans and correct condensate lines. OEM parts when available, quality aftermarket with documented specs when not.
- 5
Sanitizing treatment and verification. We apply EPA-registered sanitizer to all duct surfaces, then run the system and capture after photos of every run. The documented photo record is delivered as part of your standard job record, not an upsell.
- 6
365-Day Done Right Promise activation. Your written guarantee goes into effect the moment we leave. If the work isn’t right, we make it right - backed in writing, not subject to manager approval.

Why Leander Homeowners Call CleanRun Duct Repair & Cleaning for Honeywell Work

We’ve been running crews through Leander since 2013, including regular jobs in Crystal Falls where the combination of cedar pollen and new-construction debris makes ductwork maintenance a real conversation, not a sales pitch. Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We also service Lennox, Trane, and Carrier systems, so when your Honeywell components interface with another brand’s equipment, we don’t guess at the integration.
The 365-Day Done Right Promise is written on every job, not just stated in marketing copy. The documented photo record is standard, not optional. And the price you sign is the price you pay - Haven Standard Clause 1, no exceptions.
FAQs
No, proper sanitizing and maintenance does not void Honeywell’s warranty, provided the work is performed by qualified technicians using compatible parts and methods. We document every step so you have a record if a warranty question ever arises. As an independent Honeywell service provider, we are not affiliated with or authorized by Honeywell, but we follow manufacturer specifications for all component handling. Call (737) 252-1285 if you need clarification on your specific model’s warranty terms.
Honeywell OEM parts are our first choice for electronic components like UV lamps and zone board actuators, where calibration matters. For media filters and seal gaskets, quality aftermarket equivalents with verified specs perform identically at lower cost - we show you the spec sheet and let you decide before work begins. Haven Standard Clause 1 means that choice is built into your written price, not sprung on you mid-job.
You receive a documented photo record of every duct run, before and after, as a standard deliverable on every job. We also provide the written scope you signed, the final invoice matching that scope, and your 365-Day Done Right Promise in writing. If the photo doesn’t show clean metal, we didn’t charge for clean metal.
Most Leander homes benefit from whole-system sanitizing every 3-5 years, but homes near active construction, with pets, or with TrueDRY dehumidifiers that developed prior drain issues may need it every 2-3 years. The cedar pollen season here runs February through April, and we’ve found that homes without proper plenum sealing show accelerated buildup. We inspect first and recommend based on what the camera shows, not a calendar.
Most F100 and F200 units are repairable for 10-15 years if the cabinet is intact; replacement typically makes sense only when the control board fails and OEM parts are discontinued, or when the unit was improperly sized from installation. We test every component, quote repair and replacement options in writing, and let you decide. Free second opinion on any written estimate - bring us a competitor’s quote and we’ll put our number next to it.
