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.

AfterWhy Alpharetta Homeowners Choose Carrier Air Duct Cleaning
CleanRun Air Duct Cleaning Alpharetta provides independent Carrier repair in Alpharetta, including air duct cleaning service throughout North Fulton County, specializing in the Infinity, Performance, and Comfort series systems found in the city’s large two-story subdivision homes. Our work differs from standard duct cleaning because we treat the air handler, evaporator coil, and blower assembly as part of the same system - not a separate box in the attic. We are not affiliated with or authorized by Carrier; we are an independent service provider that documents what we find before recommending any work. Call (678) 679-7540 for a written estimate.
Alpharetta’s housing stock makes this approach necessary. The 3,000-5,000+ sq ft homes built during the 1990s-2000s growth explosion in Windward and along the GA-400 corridor commonly run two or three aging Carrier systems now hitting the 20-30-year mark. These are not small units. When a Carrier Infinity 24VNA variable-speed air handler starts short-cycling or a 58-series furnace begins tripping the high limit, the cause is often inside the ductwork - debris-choked coils, blower wheels thrown out of balance, or return plenums leaking so badly the system cannot maintain static pressure. We have cleaned and sealed enough of these systems in Alpharetta to recognize the pattern before we open the first panel, and we also handle Carrier repair in Roswell for homes with similar aging systems.
Why Trust CleanRun Air Duct Cleaning Alpharetta for Your Carrier Air Duct Cleaning?
Tomas Reyes, our owner, learned the mechanical trades at Bronx Community College and spent nearly two decades working HVAC systems across the Northeast before relocating the business south. He has since put in years cleaning residential and commercial duct systems throughout Alpharetta, including a stretch of homes near Avalon where the construction debris left in the ductwork during the build phase still surprises him. That background matters on Carrier jobs because the Infinity series variable-speed electronics and the 58-series condensing furnace heat exchangers require someone who understands airflow dynamics, not just vacuum attachments.
Our technicians are background-checked, uniformed, and identified by name before arrival - Haven Standard Clause 3: Verified Crews. We carry professional-grade equipment from Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman, and we stock genuine Carrier OEM blower wheels, limit switches, and igniters for exact-fit repairs. Every job starts with a written price before any work begins, Haven Standard Clause 1, and concludes with a Documented Photo Record of every duct run, delivered as a standard deliverable. The camera goes in first. Everything else follows from what it shows.
We also honor our 365-Day Done Right Promise in writing on every job - if the work is not right, we make it right. Not a policy subject to manager approval. A written guarantee.
Common Carrier Air Duct Cleaning Problems We Fix in Alpharetta
- Carrier Infinity N-coil evaporators choked with biological growth. The 24ANB/25HNB and 24VNA variable-speed air handlers use a slab-style N-coil that sits directly in the airflow path. In Alpharetta’s climate - high humidity cycling through attic-mounted systems from April through October - these coils become matted with dust and microbial growth that restricts airflow and forces the compressor to run hotter. The Infinity’s variable-speed blower tries to compensate, which masks the problem until the system short-cycles or the homeowner notices uneven cooling. We remove the coil, clean it with foaming cleaner and low-pressure rinse, and photograph the before and after.
- Carrier 58-series furnace blower wheels caked with debris. The squirrel-cage blower in Carrier 58STA/58STX and 59MN7/59TP6 gas furnaces pulls return air through leaky duct chases in Alpharetta’s flex-duct attic installations. Over years, this debris builds up on the blower vanes, throwing the wheel out of balance and reducing static pressure. The result is reduced airflow to distant rooms and high-limit trips when the heat exchanger cannot shed heat fast enough. We remove, clean, and rebalance the blower assembly, then seal the return plenum leaks with mastic.
- Failed mastic and taped joints on Carrier flex duct runs. Alpharetta’s original 1990s-2000s subdivision builds used flex duct routed through hot unconditioned attics. The temperature swings degrade the mastic and foil tape at plenum connections. On Carrier zoned systems, this creates pressure imbalance - one zone starved for air, another over-pressurized - and the homeowner gets hot and cold rooms despite the thermostat reading normal. We pressure-test the system, locate the leaks, and reseal with fresh mastic and mechanical fasteners.
- Secondary heat exchanger fouling in Carrier 58-series condensing furnaces. These high-efficiency units extract so much heat that the secondary exchanger runs cool enough for condensation to form. When return air is dirty - common in Alpharetta homes with degraded flex duct pulling attic air - the condensate traps particulates on the exchanger fins. Efficiency drops. The furnace runs longer. Equipment life shortens. We clean the secondary exchanger and address the return-air quality that caused it.
- Original duct board plenums shedding fiberglass liner inward. This is the failure mode we find almost exclusively in Alpharetta’s 1990s housing cohort. The duct board plenums attached to Carrier air handlers in Windward and similar subdivisions have reached an age where Georgia’s humidity cycling has degraded the interior liner. It sheds into the airstream as visible particulates. Homeowners almost never suspect it until our camera shows the fuzzy interior surface flaking away. We replace the plenum with new duct board or sheet metal, sealed and insulated to current standard.

AfterCarrier Parts & Our Repair-vs-Replace Approach
We stock genuine Carrier OEM replacement parts for exact-fit repairs: blower wheels, limit switches, hot surface igniters, pressure switches, and control boards for the Infinity, Performance, and Comfort series. For ductwork components - flex duct, mastic, duct board, register boots - we use quality aftermarket products that meet or exceed Carrier’s published specifications for static pressure and temperature rating.
Our repair-vs-replace decision is straightforward. If a Carrier air handler or furnace is within its service life and the heat exchanger is sound, we clean, seal, and repair. We will not push a full system replacement when component-level work solves the problem. The only way to know which category you are in is to inspect the equipment. We do that for free, put the findings in writing, and attach a written price before any work starts. Call (678) 679-7540 to schedule.
Our Carrier Service Process - Step by Step
- 1
Diagnosis with documentation. We remove the access panels on your Carrier air handler or furnace and run a camera through the return and supply ductwork. The photo record begins here - coil condition, blower wheel balance, plenum integrity, and flex-duct connections. We measure static pressure across the coil and document particulate buildup in mils.
- 2
Written scope and price. Before any cleaning or repair begins, we deliver a written scope of work with a fixed price. Haven Standard Clause 1. No per-vent pricing. No add-ons once the truck is in your driveway. One flat price per system, agreed in writing.
- 3
Cleaning, sealing, and component repair. We clean the evaporator coil, blower assembly, and heat exchanger using manufacturer-compatible methods. We seal duct leaks with mastic. We replace failed components with OEM or spec-matching parts. Every duct run is photographed before and after.
- 4
System test and verification. We restore power, run the system through a complete heating or cooling cycle, and verify static pressure, temperature rise, and airflow at the registers. The system must perform to Carrier’s published specifications before we sign off.
- 5
Deliverables and warranty. You receive the Documented Photo Record, the written scope, and the 365-Day Done Right Promise in writing. If anything is not right, we make it right.

FAQs - Carrier Air Duct Cleaning Service in Alpharetta
No. We are an independent service provider, not affiliated with or authorized by Carrier. We base our recommendations on what we measure inside your ducts and equipment, not on manufacturer marketing materials. Our independence means we can recommend cleaning and repair when a dealer might push replacement.
A dirty N-coil in a Carrier Infinity 24VNA or 24ANB restricts airflow, which forces the variable-speed blower to work harder and the compressor to run at higher head pressure. The system compensates until it cannot, then short-cycles or fails to hold setpoint. We have measured static pressure drops of 0.3 inches or more across coils that looked clean from the outside. After professional cleaning, the system typically returns to manufacturer-specified airflow with lower amp draw. Call (678) 679-7540 for an inspection and written estimate.
The smell is usually microbial growth on the blower wheel or in the return plenum, caused by years of debris accumulation and Alpharetta’s humidity. The 58STA/58STX and 59MN7/59TP6 pull return air through flex duct that degrades over time, and leaks in that ductwork draw attic air loaded with pollen and moisture. When the blower starts, it disturbs the growth. We clean the blower assembly, treat the plenum, and seal the return leaks with mastic to stop the infiltration.
Yes. We use negative-pressure extraction with soft-bristle rotary brushes sized to flex-duct diameter, not aggressive mechanical agitation. Alpharetta’s 1990s-2000s flex duct is already aged; we inspect each run with a camera first and note any sections where the liner is degraded or the wire reinforcement is exposed. Those sections are flagged for repair or replacement before cleaning proceeds. The camera goes in first. Everything else follows from what it shows.
No, provided the work is done by a qualified technician using manufacturer-compatible methods. We do not use caustic chemicals on Carrier coils or high-pressure water that could damage the N-coil fins. Our documentation - the photo record and written scope - protects you if a warranty question ever arises. We are not a Carrier dealer, but our work is performed to standards that do not compromise factory coverage.
For Carrier systems in Alpharetta’s pollen-heavy, high-humidity environment, we recommend evaporator coil and air handler cleaning every 3-5 years, with duct sealing inspection at the same interval - the same schedule we follow for Carrier Air Duct Cleaning in Johns Creek, GA. Homes in Windward and similar 1990s subdivisions with original flex duct may need more frequent attention as the ductwork itself ages. The only way to know your system’s condition is to inspect it. We provide free written estimates - call (678) 679-7540.
