We’ve been driving out to Marietta from our Atlanta base for twenty years, and we know the difference between a quick vacuum job and actual HVAC cleaning. Our HVAC Cleaning team handles everything from evaporator coils to condensers to full air handler teardowns — and we do it with the owner, Scott Gray, on every job. Marietta’s mix of 1970s ranches and sprawling East Cobb colonials presents specific problems: sagging flex duct, pollen-packed return grilles, and attic heat that degrades components faster than almost anywhere in the metro. We don’t dispatch franchise crews. Scott works the equipment himself.
Why Everest Air Duct Cleaning Service Georgia Is Marietta’s Preferred HVAC Cleaning Company
Marietta homeowners research before they call, and the numbers are easy to verify: 433 verified reviews averaging 4.9 stars — one of the highest review volumes in the air duct cleaning niche. That consistency matters in a market where one bad job means pollen and mold keep circulating for years.
Scott Gray has worked every job for 20 years — your home gets the owner, not a substitute. When we’re headed to Marietta, we’re typically on-site in 24–48 hours, and we know the territory: the slab-on-grade ranches off Whitlock Avenue in 30064, the two-story colonials near Barrett Parkway in 30062, the aging flex duct systems in West Marietta’s 30008 subdivisions. Two decades of crawlspace-level experience goes into every inspection.
We use Rotobrush contact-cleaning and Nikro HEPA extraction — the same equipment trusted in commercial remediation. From dirty ducts to repaired, sealed, and sanitized — we handle the full scope. That means no second company to call when we find torn flex duct or a corroded coil pan.
Our HVAC Cleaning Services in Marietta
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and does the actual cooling — but in Marietta, it’s also where pollen and humidity meet. When that yellow-green pine pollen packs onto the coil fins and mixes with condensation from our 70°+ dew points, you get a biofilm that reduces airflow and breeds mold. We remove the coil assembly when accessible, clean with foaming agents, and verify fin integrity. A typical evaporator coil cleaning in Marietta runs $180–$340.
Coil Treatment
Cleaning without treatment is half a job in this climate. Our coil treatment applies a protective layer that inhibits microbial regrowth — critical in Marietta, where the contamination cycle repeats every spring and summer. We treat after every deep clean, especially in homes with allergy sufferers or recent renovation dust. Coil treatment as an add-on runs $85–$150; bundled with full HVAC cleaning, it’s often discounted.
Air Handler Cleaning
The air handler is the heart of your system — blower motor, housing, drain pan, and filter rack. In Marietta’s older homes, particularly the 1980s–90s East Cobb builds with attic-mounted units, these components sit in 140°F+ summer heat that bakes debris into place. We disassemble the blower, clean the housing with contact brushes, clear the drain line, and inspect the pan for corrosion. Air handler cleaning in Marietta typically costs $220–$420 depending on access and contamination level.
Blower Cleaning
The blower wheel moves all your conditioned air. When pollen and pet dander coat the blades, airflow drops and the motor strains — you’ll feel it as weak vents and rising power bills. In Marietta’s multi-zone homes with 20-plus supply runs, a dirty blower works overtime. We remove the wheel, clean each blade, balance the assembly, and test amp draw. Standalone blower cleaning runs $150–$280.
Condenser Cleaning
Your outdoor condenser coil faces Marietta’s pollen onslaught directly — those loblolly pines don’t discriminate between your car and your AC unit. We wash the fins with low-pressure foaming cleaner, straighten damage, and clear the base pan. A clean condenser runs 10–15% more efficiently, which matters when your system’s working six months straight. Condenser cleaning in Marietta: $120–$220.

Heat Exchanger Cleaning
For gas furnace systems common in Marietta’s 1970s–80s builds, the heat exchanger needs annual inspection and cleaning to prevent dangerous combustion byproduct buildup. We inspect for cracks — a safety-critical step — and clean soot and corrosion. This service runs $180–$320 and is often bundled with fall preseason maintenance.

Trusted Brands We Service in Marietta
We maintain and clean systems from Carrier, Trane, Lennox, Goodman, Rheem, and York — the brands you’ll find in most Marietta homes. For air quality upgrades, we install Honeywell and Aprilaire whole-house filtration and UV systems in-house, so you don’t need a second contractor. We stock common Marietta-area parts and can source same-day from Atlanta distributors when needed. That means faster turnaround and no waiting on a parts run from out of state.
Common HVAC Cleaning Problems We See in Marietta Homes
- Sagging flex duct traps debris in low points. In East Cobb’s 1980s–90s subdivisions, long attic runs sag where straps failed, creating collection points for pollen and organic matter that standard truck-mount equipment can’t reach without multiple attic access points.
- Return-air grilles pack with year-over-year pollen accumulation. Marietta’s loblolly pine and willow oak canopy produces some of the heaviest pollen counts in the nation, and that yellow-green coating doesn’t stop at your windows — it pulls directly into ductwork through intake vents.
- Condensation biofilm forms on coil and duct surfaces every summer. When Georgia’s dew points hit the low 70s, moisture condenses on poorly insulated attic ductwork and evaporator housings, creating ideal conditions for mold growth inside the system.
- Multi-zone systems hide contamination in isolated runs. Large East Cobb homes with 20-plus supply runs often have zones that see little airflow; without inspecting every trunk and branch, contamination persists in areas the homeowner never checks.

FAQs — HVAC Cleaning in Marietta
Marietta sits inside one of the worst pollen corridors in the United States — Cobb County’s dense canopy of loblolly pines, willow oaks, and sweet gums produces heavy yellow-green pollen every spring that pulls directly through return-air grilles and packs into flex duct interiors. That pollen doesn’t flush out with normal airflow; it accumulates year over year, mixing with summer condensation to form a mold-friendly biofilm. We address this with deep contact cleaning of the full duct run, not just visible vents. Call (877) 565-7296 to schedule — estimates are free.
For Marietta’s climate, we recommend full HVAC cleaning every 2–3 years for standard households, and annually for homes with allergy sufferers, pets, or recent renovations. The compounding pollen-humidity cycle here accelerates contamination faster than in drier metros. Homes with aging flex duct systems — common in 30062 and 30008 — may need more frequent inspection. Call (877) 565-7296 and we’ll assess your specific system.
The evaporator coil is one component inside the air handler — the coil does the heat exchange, while the air handler includes the blower, housing, drain pan, and filter rack. We can clean just the coil, but in Marietta’s contaminated environment, a full air handler cleaning is usually warranted since pollen and mold spread throughout the unit. Coil-only service runs $180–$340; full air handler cleaning is $220–$420. Call (877) 565-7296 for a recommendation based on your system condition.
Yes — significantly in Marietta. The 1970s–1990s builder-grade flex duct common across East Cobb and West Marietta sags, tears at joints, and harbors debris that rigid metal duct doesn’t. Older systems require careful handling to avoid damage during cleaning, and we often find issues — disconnected runs, crushed sections, failed straps — that need repair before cleaning is effective. We carry repair capability so you’re not left calling a second company. Call (877) 565-7296 for an inspection.
A clean system runs 10–25% more efficiently, which translates to real savings when your AC runs six months straight in our climate. In Marietta specifically, we’ve measured airflow improvements of 30%+ after cleaning pollen-caked coils and blower wheels in homes near Barrett Parkway and Sandy Plains Road. Lower amp draw, faster cooling cycles, and less runtime all reduce your monthly bill. Call (877) 565-7296 for an efficiency assessment — estimates are free.
