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 Duct Cleaning in Round Rock: What to Know First
CleanRun Duct Repair & Cleaning provides independent Honeywell air duct cleaning in Round Rock for residential and light commercial systems, with most jobs completed in a single scheduled visit. A typical whole-system cleaning for a Honeywell-connected duct network runs $380-$620 for homes under 3,500 square feet, and every price is written and agreed before we touch a single panel. We’re not affiliated with Honeywell; we service their equipment as an independent provider with no manufacturer authorization. This page is for Round Rock homeowners running Honeywell whole-home air cleaners, media filters, or UV systems who want the work documented, not guessed at. Call (737) 259-5752 to schedule a free estimate.
How Honeywell Products Fail - and How We Fix Them
- F100 and F200 Media Air Cleaner frames warp from Cedar Park-to-Round Rock heat cycling. The plastic frame rails on these whole-house media cabinets expand and contract across our 40-60 degree daily temperature swings from April through October. Once the frame loses square, the 4-inch MERV filter gaps at the corners and bypass air carries pollen straight into the evaporator coil. We measure frame deflection with a straightedge, replace warped rails with Honeywell-spec aluminum extrusions where available, or source equivalent rigid frames that maintain seal pressure. The camera goes in first. Then we talk.
- F300 Electronic Air Cleaner cells develop intermittent arcing after cedar pollen season. The ionizing wires in these electrostatic units collect sticky pollen particulate that hardens into insulating jackets. Homeowners in Teravista and Stone Oak Ranch call us in July when the unit starts snapping - that’s the power supply hunting for ground through contaminated wires. We remove the cells, clean with manufacturer-approved solution, inspect for wire sag beyond 1/8-inch, and test ionization current draw before reassembly. Never pressure-wash F300 cells; the ceramic insulators crack and the warranty is void.
- UV2400 and UV100 UV lamp systems lose output without warning indicators. Honeywell’s UV lamps run 9,000 hours before rated degradation, but Round Rock’s hard water scale and high calcium content coats quartz sleeves faster than coastal climates. We pull the lamp, measure actual UVC output with a calibrated radiometer, and replace sleeves that transmit less than 70% of rated intensity. Most homeowners don’t know the lamp is decorative until we show them the sleeve photo.
- DR90 and DR120 whole-home dehumidifier drain pans crack from Texas limestone dust infiltration. These units mount to return plenums and their plastic pans fatigue where construction dust from ongoing Round Rock development settles and holds moisture. We find the crack with borescope inspection, replace with OEM pan or fabricate equivalent from UV-stabilized polymer, and add a secondary float switch under Haven Standard Clause 5: Redundant Safeguards.
- TrueCLEAN FH8000 bypass dampers stick in partial-open position. The damper motor gears strip gradually, leaving the unit neither fully filtering nor fully bypassing. Our techs test damper travel with the thermostat calling for fan-only versus cooling, measure pressure drop across the media, and replace the actuator with Honeywell OEM or verified equivalent - aftermarket dampers with incorrect torque specs burn out in two seasons.
Our Honeywell Air Duct Cleaning Process

- 1
Video inspection of every main trunk line. Tomas Reyes runs a borescope through the supply and return plenums before quoting, so the homeowner sees the debris load we’re pricing to remove.
- 2
Written scope and price delivered. Haven Standard Clause 1: no work starts without a signed written estimate. The price covers the whole system, not per-vent arithmetic.
- 3
Negative-pressure extraction with equipment matched to duct material. We use Rotobrush contact cleaning for flex duct common in 2015-2022 Round Rock builds, or Nikro HEPA-contained vacuum for rigid metal trunk lines in older homes near downtown.
- 4
Honeywell component service or replacement. Media filters, UV lamps, and electronic cells are addressed with OEM or verified-equivalent parts - never universal-fit substitutions that void remaining warranty coverage.
- 5
Post-cleaning photo record and airflow verification. Every duct run is photographed after cleaning, pressure readings are logged, and the 365-Day Done Right Promise is issued in writing before we leave.

Why Round Rock Homeowners Call CleanRun Duct Repair & Cleaning for Honeywell Work

We’ve served Round Rock since 2013, including repeat jobs in Stone Oak Ranch where cedar pollen loads are measurable in pounds per system. Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The 365-Day Done Right Promise is not a marketing line - it’s a written guarantee on every job, backed by the photo record that proves what was done. Tomas Reyes and his crew have handled Honeywell equipment long enough to know which part numbers cross-reference and which don’t, and we publish our license number where customers can verify it. We’re independently owned and operated, not a franchise, and we answer calls with live people 24/7.
FAQs
No. Professional air duct cleaning performed by a qualified technician does not void Honeywell’s equipment warranty, provided no components are damaged during service. We use manufacturer-specified cleaning methods for electronic cells and UV lamps, and we document our process in the photo record so warranty claims remain clean if you ever need them. For specific concerns about your model, call (737) 259-5752 and we’ll review your warranty status before scheduling.
OEM Honeywell media filters maintain the exact MERV rating and pleat spacing the cabinet was engineered for; aftermarket filters with higher MERV but incorrect pleat count can collapse or bypass. We stock OEM F100/F200 media and will show you the difference in frame fit before you decide. If you prefer aftermarket, we source from Guardsman and Aprilaire with verified pressure-drop specs that match Honeywell operating ranges.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every job - not upon request, not for an extra fee. The photo record is time-stamped and includes the register location. If we can’t show you the inside of your ductwork, we didn’t do the work. Haven Standard Clause 2: Documented Accountability.
Usually not. Arcing typically indicates contaminated ionizing wires or cracked ceramic insulators, both serviceable items. We test the power supply output, clean or replace wires, and replace individual insulators. Full F300 replacement runs $800-$1,400; most arc repairs are $180-$340. We’ll show you the failed component on camera before quoting either path.
Every 3-5 years for homes without pets or recent construction; every 2-3 years if you have shedding animals, completed renovation within 18 months, or live downwind of active development like the expansion along University Boulevard. Cedar pollen season here deposits enough particulate to measurably load media filters in a single spring. Call (737) 259-5752 and we’ll scope your system to tell you where you actually stand.
