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 Sandy Springs: What to Know First
CleanRun provides independent Honeywell air quality and sanitizing service in Sandy Springs, with most scheduled jobs completed in a single visit and a written price delivered before any work begins. A typical Honeywell UV light installation or whole-home sanitizer treatment runs $340-$780 depending on the series and whether your plenum - the main distribution box attached to your air handler - needs modification to accept the unit. We are not affiliated with or authorized by Honeywell; we are an independent service provider that stocks Honeywell-compatible components alongside Lennox, Trane, and Carrier parts so we can match the right solution to what is actually installed in your home.
This page is for Sandy Springs homeowners running Honeywell F300 electronic air cleaners, UV2400 or UV100 series ultraviolet systems, or whole-house dehumidifier-integrated air quality setups who want documented results rather than a sales pitch. Call (678) 904-9744 to schedule. Estimates are free, and we will put our written price next to any competitor’s quote under our Free Second Opinion policy.
How Honeywell Products Fail - and How We Fix Them
- F300 Electronic Air Cleaner power supply failures. The F300E1019 and F300E1027 units common in Sandy Springs homes built 2015-2020 use a transformer-based power supply that degrades in Georgia’s high-humidity shoulder seasons. The ionizing wires still arc, but the collection cells stop holding voltage. We test output with a calibrated meter, replace the power module with an OEM or equivalent-rated aftermarket unit, and photograph the cell plates before and after cleaning so you can verify the 4,000-volt field is restored.
- UV2400 lamp degradation in encapsulated coils. Honeywell’s UV2400 series mounts inside the plenum, but the 24V lamp sockets oxidize where Sandy Springs’ clay-heavy soil creates slight ground moisture migration through slab foundations. The lamp looks lit but drops below the 254-nanometer germicidal threshold. We measure actual UVC output with a radiometer, not just visual inspection, and replace the lamp and socket assembly when the reading falls below 40 microwatts per square centimeter.
- UV100 timer board false “replace lamp” signals. The UV100E3009 uses a 365-day countdown timer that triggers even on lamps with viable output. Homeowners in the Spalding Drive corridor - where older ranch homes have extended duct runs - often replace lamps prematurely. We verify actual UVC output first, reset the board only when the lamp is genuinely spent, and document the reading in your job record so you are not buying $89 lamps on a calendar schedule.
- F100 media cabinet bypass leakage. The F100F2028 media air cleaner seals with a foam gasket that compresses permanently after three to four filter changes. Unfiltered air bypasses the MERV 11 media, carrying pollen and mold spores into the supply ductwork. We replace the gasket with a denser closed-cell equivalent, check the cabinet rails for distortion from overtightening, and pressure-test the seal before closing the access panel.
- Whole-home dehumidifier drain pan biofilm. Honeywell’s TrueDRY DR90 and DR120 units, often paired with Trane or Carrier systems in Sandy Springs’ 2018-2023 construction, develop pink bacterial film in the condensate pan that aerosolizes during fan cycling. Standard cleaning misses the pan corners. We disassemble the pan, treat with a non-corrosive sanitizer rated for HVAC components, and photograph the pan interior before reassembly so you can see the difference between surface wiping and actual remediation.
Our Honeywell Air Quality & Sanitizing Process

- 1
Photo-first inspection. We access the plenum and photograph the existing Honeywell component, the surrounding ductwork, and any visible microbial growth or debris buildup before touching a tool. The photo comes first. The invoice comes second.
- 2
Written scope and price. Haven Standard Clause 1 requires a written price before work starts. We itemize parts - OEM Honeywell or equivalent aftermarket, your choice - labor, and any plenum modifications needed to accommodate a UV lamp or electronic air cleaner upgrade.
- 3
Component testing with documented readings. For UV systems, we record UVC output in microwatts per square centimeter. For electronic air cleaners, we test ionizing voltage and airflow resistance across the collection cell. These numbers go in your job record.
- 4
Service or replacement with photo documentation. We perform the agreed work and photograph every duct run, the component interior, and the completed installation from multiple angles. You receive these images as a standard deliverable, not an upsell.
- 5
Operational verification and written guarantee. We run the system through a complete cycle, verify the Honeywell component is communicating properly with the thermostat or air handler board, and leave you with the 365-Day Done Right Promise in writing. If the work is not right, we make it right.

| F100 media cabinet reseal | $160-$280 | Gasket material grade, rail realignment needs |
| Whole-home sanitizer treatment (mold/bacteria) | $340-$620 | Number of duct runs, contamination severity, dehumidifier pan disassembly required |

Why Sandy Springs Homeowners Call CleanRun Duct Repair & Cleaning for Honeywell Work

We have been working Sandy Springs since 2013, including repeated jobs in the Spalding Drive corridor where the ductwork in 1960s and 1970s ranch homes predates modern air quality components. Tomas Reyes and our crew know how to fit Honeywell UV and electronic air cleaner retrofits into tight plenum spaces without damaging the original galvanized ductwork.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. We carry Honeywell, Aprilaire, and Guardsman components on the truck, plus Lennox, Trane, and Carrier parts for mixed-brand systems. The 365-Day Done Right Promise is backed in writing on every job, and the Documented Photo Record - inside every duct run, before and after - has been standard since our first service call. You do not have to trust our description of clean ducts. You can look at the photograph.
FAQs
No. Routine maintenance and compatible part replacement by an independent service provider do not void Honeywell’s product warranty, though using non-Honeywell parts may shift certain coverage terms. We document every part number installed and will note whether we used OEM Honeywell or an equivalent-rated aftermarket component so you have a complete record. Call (678) 904-9744 if you need warranty documentation for a claim.
We measure UVC output with a calibrated radiometer and record the microwatt reading in your job record. A lit lamp does not guarantee germicidal output - phosphor-coated lamps can glow without producing effective 254-nanometer UVC. The photograph and the number together tell you what you paid for. If the reading drops below threshold within 365 days, we replace it under our Done Right Promise.
It depends on what the inspection shows. If the power supply and cell plates are intact, the F300 filters more effectively than standard media at 0.3 microns. If the cell plates are corroded or the power supply is obsolete, a modern F100 media cabinet often costs less to maintain long-term. We will show you the photographs and the written prices for both paths before you decide. No default recommendation - just the evidence.
Most single-lamp UV100 or UV2400 installations in Sandy Springs homes take two to three hours, including plenum access, cutting and sealing the mounting location, wiring to the 24V transformer, and operational testing. Dual-lamp configurations or jobs requiring plenum modification for clearance add time. We schedule by the job, not the hour, and the written price does not change if the work runs long.
The $79 coupon model typically covers a brief vacuum at the register and a visual scan. It does not include photography inside every duct run, UVC output measurement, or a written guarantee backed for 365 days. We have pulled inspection cameras behind those cheap cleanings and found the same debris at the elbows that was there before the truck arrived. The difference is not price. It is what was actually done, and whether you can prove it.
