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 HVAC Cleaning in Marietta: What to Know First
We provide independent Honeywell HVAC cleaning in Marietta, Georgia, for homeowners who need their evaporator coils, blowers, condensers, air handlers, and heat exchangers cleaned without voiding factory warranties. Most Honeywell jobs are completed in a single scheduled visit, with a written price delivered before any panel comes off. A typical coil-and-blower cleaning runs $280-$420 for a standard residential system, while full air handler service with heat exchanger inspection ranges $450-$680.
This page is for Marietta homeowners with Honeywell systems installed between 2015 and 2023, especially those who received a “dirty coil” flag from their HVAC tech and want the work done by someone who documents what was actually found. We’re not affiliated with Honeywell, and we don’t sell new systems. We clean what you own and show you the photo record. Call (470) 516-9337 for a written estimate.
How Honeywell Products Fail - and How We Fix Them
- Prestige IAQ and T Series thermostats with integrated zoning boards. The zoning dampers in Marietta’s 2018-2021 builds often seize from Georgia pollen and red-clay dust infiltration through poorly sealed return plenums. We photograph the damper positions before touching anything, then clean the actuator linkage and reseat the plenum seal so the board stops throwing false “damper fault” codes.
- TrueCLEAN electronic air cleaners (FGC series). The ionizing wires in these units collect a conductive film of cooking grease and pet dander that the homeowner can’t see without removing the cell. We see this in East Cobb and Indian Hills kitchens regularly. Our process pulls the cell, cleans it with a solution that won’t etch the tungsten wires, and tests ionization current with a microammeter before reinstalling.
- Whole-house dehumidifiers (DR series, especially DR90). The evaporator coil in these units runs colder than the main HVAC coil, so biological growth builds faster. In Marietta’s shoulder seasons, when outdoor dew points sit above 65°F for weeks, we find slime accumulation blocking the condensate drain pan. We clean the coil with a non-acid foaming agent, clear the drain line with positive-pressure flush, and treat the pan with a polymer coating that doesn’t void the warranty.
- Media air cleaners (FC100A and FC200E cabinet filters). Homeowners often install the wrong MERV rating or forget the directional arrow, which overloads the blower motor and cakes the coil with bypassed debris. We check filter orientation on every visit, measure static pressure across the media cabinet, and clean the blower wheel if the imbalance has already thrown grit into the housing.
- ZonePerfect and older HZ series zone panels. The DIP switches on these panels corrode from humidity in Marietta basements and crawl spaces, causing intermittent communication failures that look like thermostat problems. We clean the board contacts with electronics-grade solvent, verify switch integrity with a continuity test, and document the panel firmware version in case Honeywell support needs it later.
Our Honeywell HVAC Cleaning Process

- 1
Written price before arrival. We scope the work over the phone using your model numbers, then deliver a fixed price in writing. No “call for a quote.” Haven Standard Clause 1.
- 2
Diagnostic with photo documentation. The technician arrives uniformed and identified by name, per Haven Standard Clause 3: Verified Crews. We access the coil, blower, or heat exchanger and photograph the condition before touching anything.
- 3
Parts decision: OEM or verified aftermarket. For Honeywell-specific components like TrueCLEAN cells or dehumidifier drain pans, we use OEM when the warranty is active. For universal items like blower wheels or contactors, we use quality aftermarket brands that meet Honeywell’s published specifications.
- 4
Cleaning with trade-grade equipment. We use Rotobrush and Nikro negative-pressure extractors for duct-adjacent work, and Abatement Technologies HEPA containment when biological growth is present. Honeywell equipment is named in our job record so you can verify specifications independently.
- 5
Post-clean testing and photo record delivery. We measure temperature split, static pressure, and amperage draw against Honeywell’s service manual ranges. The before-and-after photo record is delivered as a standard job deliverable, not an upsell.
- 6
365-Day Done Right Promise in writing. If the work is not right, we make it right. The promise is printed on your invoice, not just stated in marketing copy.

AfterWhat Honeywell HVAC Cleaning Costs in Marietta
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning | $280-$380 | Coil accessibility (A-frame vs. slab), biological growth present |
| Blower wheel & housing cleaning | $220-$320 | Wheel removal required, bearing condition |
| Condenser coil cleaning | $180-$260 | Fins damaged, refrigerant access needed |
| Air handler full service (coil, blower, drain) | $420-$580 | Dual-zone systems, dehumidifier integration |
| Heat exchanger cleaning & inspection | $320-$450 | Secondary heat exchanger (90%+ furnaces) |
| TrueCLEAN electronic cell service | $150-$220 | Cell condition, wire replacement needed |
Factors that raise the price: systems in attic kneewalls with limited access, coils that haven’t been cleaned since installation, and integrated Honeywell zoning that requires damper removal to reach components. We tell you this before the work starts, not after. Call (470) 516-9337 for a written estimate - estimates are free, and we offer a Free Second Opinion on any competitor’s written quote.
Why Marietta Homeowners Call CleanRun Duct Repair & Cleaning for Honeywell Work

We’ve been the crew homeowners near Marietta Square call since 2013 when their HVAC tech says the ducts or the coil are the problem. Tomas Reyes, our owner, started in this trade at Bronx Community College and has spent well over a decade mapping return-air plenums and brushing out flex-duct runs caked with Georgia red-clay dust. He arrives with a camera scope and leaves customers with before-and-after photos they can actually read.
Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - brands you can look up before agreeing to a price. We also service Lennox, Trane, and Carrier systems, which matters when your Honeywell zoning is married to a Carrier heat pump or a Trane variable-speed air handler. The camera doesn’t lie - and neither does the invoice. Every job is backed by the 365-Day Done Right Promise, and every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3.
FAQs
No, routine cleaning and maintenance by a qualified independent provider does not void your Honeywell warranty, provided no parts are altered or replaced with incompatible components. We use OEM parts when the warranty is active and document everything in writing. If you have concerns, call (470) 516-9337 and we’ll review your warranty status before scheduling.
Our Documented Photo Record shows the coil surface before and after, with enough resolution to read fin spacing. We also measure temperature split across the coil before and after cleaning. The photo record is delivered as part of the standard job record, not as an optional add-on.
The low quote usually omits something: blower wheel removal, drain pan treatment, or the photo documentation. Some competitors quote a “coil cleaning” that is literally foaming agent sprayed from a bottle and rinsed with a garden sprayer. We quote the full scope in writing before work starts, so you know what you’re comparing.
Often yes, especially in Marietta’s September-October shoulder season when outdoor dew points stay high. The DR90’s coil may be biologically fouled, or the condensate drain may be partially blocked. We clean the coil, flush the drain, and test the unit’s moisture removal rate against its published capacity. If the compressor is failing, we’ll tell you that too - we don’t clean what needs replacing.
Every three to five years for the evaporator coil in a home with standard filtration and no pets. Homes with multiple pets, indoor smokers, or TrueCLEAN media filters upgraded to MERV 13+ may need coil cleaning every two years. The blower wheel typically follows the same interval unless you see dust at the registers. We don’t sell maintenance contracts - we tell you what the camera shows and let you decide.
