HVAC Cleaning in Marietta - Flat Price Per System, No Per-Vent Upsells

Trusted HVAC Cleaning for Marietta Homeowners

HVAC Cleaning in Marietta typically runs $280-$620 for a complete system service, and most jobs are completed in a single visit. At CleanRun Air Duct Cleaning Marietta, we’ve documented the inside of over 52,000 systems since 2013, and what we find in Cobb County homes is consistent: evaporator coils choked with pollen and fine dust from the red-clay hills, blower wheels caked with pet dander, and condensers clogged with cottonwood fluff from the Chattahoochee corridor. These aren’t abstract problems. They’re measurable restrictions that show up on your power bill and in the air your family breathes. We don’t sell fear. We photograph what we find, write the price before touching a single panel, and let the evidence speak. Call (470) 516-9337 for a free, written estimate with no obligation to book.

Every technician we send to Marietta is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. The equipment on our trucks includes Rotobrush, Nikro, and Abatement Technologies systems - brands you can look up yourself before you agree to anything. Our 365-Day Done Right Promise is backed in writing on every job, not buried in a policy manual. If the work isn’t right, we make it right. That’s Haven Standard Clause 5, and it’s non-negotiable.

What Our HVAC Cleaning Service Includes

Evaporator Coil Cleaning

The evaporator coil sits inside your air handler and acts as the cold surface where indoor air gives up its heat and moisture. In Marietta, we regularly find these coils restricted by a blanket of pollen, skin cells, and fine particulate that the standard 1-inch filter never catches. A dirty coil can’t transfer heat efficiently, so your compressor runs longer, your humidity stays higher, and your energy use climbs. Our process removes the coil assembly when accessible, applies foaming cleaner formulated for aluminum fins, and rinses with controlled low-pressure water to avoid fin damage. We document the before and after with photos you receive as part of your job record.

Blower Cleaning

The blower wheel - the squirrel-cage fan that pushes conditioned air through every duct run in your home - is often the dirtiest component we inspect. When balance is thrown off by uneven debris buildup, you get vibration noise, premature motor bearing wear, and weak airflow at the registers. In East Cobb homes built during the 2015-2020 boom, we’ve pulled blower wheels with debris layers thick enough to measure in fractions of an inch. We remove the blower assembly, clean each vane with compressed air and soft brushes, check motor amp draw against manufacturer spec, and reassemble. The photo record shows you exactly what was removed and what the wheel looks like now.

Condenser Cleaning

Your outdoor condenser coil rejects the heat your system removed from inside the house. Around Marietta, the combination of red clay dust, pollen, and landscaping debris means these coils foul faster than in many parts of the country. A restricted condenser raises head pressure, strains the compressor, and can trigger high-pressure safety shutdowns on the hottest July afternoons. We power down the unit, remove the fan guard when the design allows, and clean the coil fins with foaming cleaner and a fin comb. We also clear the concrete pad and check for proper clearance from shrubs - a detail that matters more than most homeowners realize in our humid subtropical climate.

Air Handler Cleaning

The air handler is the sheet-metal cabinet that houses your blower, evaporator coil, and often your electric heat strips or heat exchanger. It’s also a collection point for anything that gets past your filter. In Marietta homes with crawl space or attic installations, we’ve found rodent debris, fiberglass insulation fragments, and standing water from clogged condensate drains. Our cleaning addresses the full cabinet interior: vacuuming loose debris, wiping down surfaces, clearing and treating the condensate pan and drain line, and inspecting the insulation lining for mold or deterioration. Every step is photographed. You see what we saw.

Heat Exchanger Cleaning

Gas furnaces in Marietta see real use during our unpredictable winter cold snaps, and the heat exchanger is where combustion happens safely inside a sealed metal chamber. Soot buildup from incomplete combustion, rust from condensate leaks, or cracks from thermal cycling all compromise performance and safety. We inspect accessible heat exchanger surfaces with a borescope camera, document what we find, and clean within manufacturer guidelines. If we identify a crack or significant deterioration, we flag it immediately and provide written documentation - never a verbal warning that evaporates after we leave. This is not a service to delegate to someone without combustion safety training.

Coil Treatment

After mechanical cleaning, we offer an optional coil treatment using EPA-registered products that inhibit microbial growth on wet coil surfaces without leaving a residue that restricts airflow. This isn’t perfume masking a problem - it’s a controlled application to a clean surface, following manufacturer dwell-time specifications. In Marietta’s high-humidity months, when evaporator coils stay wet for hours after each cooling cycle, this treatment addresses the biological film that can develop even on visually clean coils. We explain the product by name, show you the label, and include the application in your written scope only if you approve it. No surprise add-ons.

Brands We Service for HVAC Cleaning

We’ve cleaned and serviced HVAC equipment from every major manufacturer installed in Marietta homes over the past two decades. On Honeywell air handlers and media filters, we stock the correct replacement dimensions and understand the bypass airflow requirements that determine whether your 4-inch media filter actually does its job. For Aprilaire whole-house humidifiers and dehumidifiers - common upgrades in the $400K+ new construction around West Cobb - we clean the water panel assemblies and distribution trays that mineral scale can clog in our moderately hard water.

We also work regularly with Nikro and Abatement Technologies equipment, though here we’re referring to the professional-grade cleaning and containment tools we bring to your home, not the HVAC brand on your thermostat. Whether you have a Trane, Carrier, Lennox, Rheem, or any other make, we can access the coils, blowers, and heat exchangers for proper cleaning. We don’t need to be the company that sold you the system to document its condition and restore its performance.

Signs You Need HVAC Cleaning Right Now

• Your energy bill climbed without a rate increase. When coils and blowers are dirty, your system runs longer to deliver the same cooling or heating. In Marietta’s summer peak, that extra runtime shows up clearly on your Georgia Power bill. We’ve seen homeowners recover the cost of cleaning in a single season of reduced consumption.
• Some rooms never reach the thermostat setpoint. Restricted airflow from a dirty blower or clogged coil can’t push enough conditioned air through the duct run to distant rooms. If your master bedroom in a two-story Kennesaw Trace home stays stubbornly warm, the problem may be at the air handler, not the duct design.
• You smell musty or sour odors when the system cycles on. That smell is microbial growth on wet coil surfaces or in standing condensate. It’s not “just how HVAC smells.” It’s a biological film that cleaning removes and proper drainage prevents from returning.
• The system short-cycles - turns on and off rapidly. A dirty evaporator coil can ice over, triggering the low-pressure switch and shutting the compressor down prematurely. The ice melts, pressure equalizes, and the cycle repeats. This wears components and never properly dehumidifies your home.
• You haven’t had the indoor components cleaned since installation. For Marietta homes built 2015-2025, that means 5-10 years of accumulated debris in a system that was designed to operate clean. The filter catches what it can. The rest settles where airflow slows - on coils, in blower vanes, and in the air handler cabinet.

Our HVAC Cleaning Process - Step by Step

1. 1
   Written estimate before arrival. When you call (470) 516-9337, we ask about your system type, age, and any symptoms you’ve noticed. We provide a written price range by email or text before scheduling. Haven Standard Clause 1: No surprises.
2. 2
   On-site inspection and final scope. Our technician arrives in a marked vehicle, introduces themselves by name, and performs a visual inspection of accessible components. If the actual condition differs from what we estimated, the price is adjusted in writing before work begins. You approve the final scope or we leave - no charge for the visit.
3. 3
   Component removal and mechanical cleaning. We power down the system, remove panels and components as the design allows, and clean each element with appropriate tools: foaming cleaner and fin combs for coils, compressed air and soft brushes for blowers, borescope-assisted inspection for heat exchangers. Every step follows manufacturer guidelines, not shortcuts.
4. 4
   Documentation and reassembly. As components are cleaned, we photograph the before and after of each. These images are compiled into your Documented Photo Record, delivered as part of your standard job record. We reassemble with proper torque on fasteners, verify electrical connections, and test operation before leaving.
5. 5
   Written deliverables and 365-Day Done Right Promise. You receive a written scope of work performed, the photo record, and your warranty documentation. If anything isn’t right in the next year, we return and make it right. That’s not a slogan. It’s Haven Standard Clause 5, and it’s in writing.
