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 Air Quality & Sanitizing in Lewisville: What to Know First
We provide independent Honeywell air quality and sanitizing service in Lewisville, TX, with most jobs completed in a single scheduled visit and a written price delivered before any work begins. Whole-system sanitizing with documented photo record typically runs $380-$620 for Lewisville homes under 3,500 square feet, depending on duct configuration and whether UV light installation is included. This page is for homeowners running Honeywell F300 Electronic Air Cleaners, UV2400U series systems, or whole-home dehumidifier-integrated setups who want the work done warranty-safe and photographed. Call (940) 240-8552 for a written estimate.
How Honeywell Products Fail - and How We Fix Them
- F300 Electronic Air Cleaner cells lose ionizing wires after 3-4 years in Lewisville’s hard water conditions. The mineral content in Denton County water accelerates corrosion on the tungsten wires, causing arcing and ozone smell. We test cell voltage with a Honeywell-compatible meter, replace wires with OEM-spec .006″ tungsten (or quality aftermarket from Guardsman when OEM backorder stretches past two weeks), and verify output to manufacturer spec before reassembly.
- UV2400U and UV100 series lamps dim without triggering the replacement indicator. The 24-volt ballast degrades gradually; output drops below 40 microwatts per square centimeter while the green LED still shows. We measure actual UV-C output with a calibrated radiometer, not just lamp hours, and install Honeywell replacement lamps or Abatement Technologies equivalents rated for the same 253.7 nanometer wavelength.
- TrueCLEAN FH8000 filters load unevenly in Lewisville homes with flex-duct sag. In Castle Hills and older Lewisville subdivisions, sagging flex creates turbulent zones where the charged media loads prematurely on one face. We photograph the filter face, note the pattern, and address the duct geometry before installing the replacement - otherwise the new filter fails the same way in eight months.
- Whole-home dehumidifier drain pans harbor mold when Honeywell’s DH65 or DH150 runs continuous in summer. Lewisville’s 70%+ July humidity overwhelms the pan’s antimicrobial coating after two seasons. We treat with EPA-registered sanitizer, install a secondary float switch if missing, and document the pan condition in the photo record.
- Air purifier communication faults between Honeywell units and third-party thermostats. The ABCD bus on newer IAQ products conflicts with some Wi-Fi thermostat firmware. We isolate the wiring, test with a Honeywell T6 Pro to confirm product function, then restore preferred thermostat control with a relay isolation - never a firmware workaround that voids the equipment warranty.
Our Honeywell Air Quality & Sanitizing Process
- 1
Written price delivered upfront. Haven Standard Clause 1: we inspect accessible components, scope the work, and put the price in writing before any panel comes off. No exceptions.
- 2
Diagnostic with photo baseline. We put a camera in every duct run, photograph the plenum (the main distribution box), and record Honeywell unit serial numbers and install dates for warranty verification.
- 3
Parts decision documented. OEM Honeywell, quality aftermarket from Aprilaire or Guardsman, or hybrid - we note the choice on the work order with reasoning, so you know what you’re paying for and why.
- 4
Sanitizing or repair executed under negative-pressure extraction. Agitation and application happen while the duct system is under controlled vacuum, so loosened debris and chemical overspray don’t enter occupied space.
- 5
Post-work test and photo record. We re-measure airflow, verify UV output or electronic cell voltage, and photograph the same duct runs for the after comparison. The photo record is delivered as a standard deliverable, not an upsell.
- 6
365-Day Done Right Promise activated in writing. If the odor returns, the cell arcs, or the UV reading drops, we make it right. The promise is on the invoice, not just the website.

| Service | Typical Range | What Moves It |
|---|---|---|
| Electronic air cleaner cell rebuild (F300 series) | $180-$290 | Wire count, cell size (16×25 vs. 20×25), corrosion severity |
| UV lamp replacement with output verification | $220-$340 | Lamp length, ballast condition, attic vs. closet access |
| Whole-system sanitizing (mold/bacteria/odor) | $380-$620 | Home size, duct count, contamination source location |
| UV light installation (new, no existing unit) | $450-$680 | Duct material, electrical run length, single vs. dual-lamp |
| TrueCLEAN filter replacement with duct correction | $260-$420 | Filter size, flex-duct repair extent, register count |
These are whole-system prices, not per-vent teaser rates. The invoice matches the written price agreed to before work started. Call (940) 240-8552 for a written estimate - estimates are free, and we provide a Free Second Opinion on any competitor’s written quote.
Why Lewisville Homeowners Call CleanRun Air Duct Cleaning Lewisville for Honeywell Work
We’ve been running jobs in Lewisville since 2013, including the older flex-duct homes near Castle Hills where Honeywell equipment was retrofitted onto systems never designed for it. Tomas Reyes and our crew know the difference between a UV lamp that lights up and one that actually sanitizes - we measure, we don’t guess. The 365-Day Done Right Promise is backed in writing on every job, and the Documented Photo Record shows you what changed inside your ducts, not just what we say changed.
We also service Lennox, Trane, and Carrier IAQ equipment, which matters when your Honeywell unit is integrated with a mixed-brand system and the fault isn’t obvious. Background-checked, uniformed technicians under Haven Standard Clause 3: Verified Crews. License number published below.

FAQs
No. As an independent Honeywell service provider, we follow manufacturer installation and repair specifications, use OEM or equivalent-rated parts, and document serial numbers and test readings. Warranty coverage depends on proper installation and genuine parts, not on whether the technician wears a Honeywell logo. We note all test values on your invoice for warranty claim support if needed. Call (940) 240-8552 if you have a specific warranty concern.
We measure UV-C output at the lamp surface with a calibrated radiometer and record the microwatt reading on your work order. A new Honeywell UV2400U lamp should read 50+ microwatts per square centimeter at one meter; we flag anything below 40 and replace under our Done Right Promise. The photo record includes the meter display. You’ll see the number, not just the glow.
The $199 quote is typically a surface spray at the register with no duct access, no photo documentation, and no post-work verification. Our $380-$620 range covers full system contact time with EPA-registered sanitizer, negative-pressure containment, every duct run photographed, and output-tested equipment. Ask any competitor for their written scope and photo record policy before comparing prices. We provide Free Second Opinions on any written estimate.
Replace if the cell housing is cracked or the power supply is obsolete (pre-2012 transformer-style units). Repair if the cell is intact and only the ionizing wires or contact pads need renewal. We photograph the cell housing, test the power supply under load, and give you both options in writing with installed cost and expected service life. No default to replacement.
Electronic air cleaner cells need annual inspection and cleaning; UV lamps need replacement every 9,000 hours (about 12 months of continuous operation) regardless of whether the indicator triggers. Lewisville’s pollen load and hard water push both intervals toward the shorter end. We note install dates and set reminders; call (940) 240-8552 to schedule.
