Trusted HVAC Cleaning for Marietta Homeowners
If your AC runs constantly but the house still feels humid, or you’ve noticed a musty smell when the system kicks on, your HVAC system is probably carrying years of accumulated dust, pet dander, and microbial growth through your vents. Full HVAC cleaning in Marietta typically runs $500 – $900 for a complete system, which includes the air handler, evaporator coil, blower assembly, supply and return plenums, and all accessible ductwork. The work usually takes 4 to 7 hours. If you want a home that breathes cleaner, call Cardinal Air Duct Marietta at (762) 216-4075 for a written, no-obligation estimate before any work begins.
Led by Omar Haddad, our technicians have been cleaning HVAC systems across Cobb County for years. We run Rotobrush rotary brush systems and Nikro HEPA-filtered negative-air machines, not a shop vac strapped to a truck. You get a written price before we touch a single vent, before-and-after photos of the actual work, and a full 365-Day Done Right Promise: if the work isn’t right within a year, we come back and correct it at no charge. That’s the standard every booking is held to.
AC Coil Cleaning
AC Coil Cleaning is the process of removing built-up dirt, dust, and biological growth from the evaporator coil inside your air handler, which is the component that actually cools the air before it moves into your ductwork. In Marietta’s humid summers, coils collect condensation constantly, and that moisture grabs airborne dust like a magnet until you’re left with a matted layer that chokes airflow and forces your system to work harder. Cardinal Air Duct Marietta cleans evaporator coils by hand with professional coil cleaners and fin combs, not just a spray-and-rinse quickie. Coil cleaning is typically included in a full HVAC cleaning, and as a standalone service it usually runs $150 – $300 depending on access. If you’re wondering how much HVAC Cleaning costs for a complete system, we break that down below.
When the Coil Needs Attention
A coil caked in grime can reduce cooling capacity by 15 to 20 percent. If your AC runs longer cycles than it used to and you’re seeing higher Georgia Power bills without a thermostat change, the coil is the first place we look.
What Professionals Actually Do
We remove the access panel, inspect for leaks or corrosion, apply a commercial-grade coil cleaner that breaks down the organic film, then carefully rinse and straighten bent fins. The result is colder supply air and less strain on the compressor.
Styles & brands we work with
AC Cleaning
AC Cleaning is a catch-all term covering the full air conditioning side of the system: the evaporator coil, blower wheel, drain pan, condensate line, and the interior of the air handler cabinet. Homeowners in Marietta often call it “AC cleaning” when they mean “my AC smells or isn’t cooling right,” and that’s exactly what we diagnose. A complete AC cleaning from Cardinal Air Duct Marietta typically runs $300 – $500 for a single system, less if bundled with HVAC Cleaning in Milton-style full-system work, and includes a written price before we begin. We also check the condensate drain line, which in Georgia is a prime spot for algae blockages that lead to water damage.
Blower Wheel and Housing
The blower wheel is a curved fan inside the air handler that pushes air through your home. When it’s coated in fuzz, it moves maybe 70 percent of the air it should. We pull the blower assembly, clean each blade, and reinstall it so airflow returns to design levels.
Condensate Drain and Pan
Standing water in the drain pan plus Georgia heat equals mold fast. We clear the line, treat the pan, and confirm water flows freely. It’s a small step that prevents a flooded utility closet.
Evaporator Coil Cleaning
Evaporator Coil Cleaning is the most important maintenance task for keeping your energy bills in check, because a dirty coil physically cannot remove heat efficiently no matter how good the rest of the system is. We charge $150 – $250 for evaporator coil cleaning as a focused service in HVAC Cleaning - Marietta, and it’s included at no extra line item when you book a full HVAC cleaning. The job involves opening the air handler, brushing and chemically cleaning both sides of the coil where accessible, and straightening fins so air can actually pass through. It typically takes 90 minutes to 2 hours.
Why Coils Get Dirty Fast Here
Marietta’s pollen season runs long, and with windows open in spring and fall, that fine yellow dust gets pulled right into the return and across the wet coil. Add pet hair and cooking grease and you have a sticky surface that never self-cleans.
Efficiency After Cleaning
A clean coil lets the refrigerant absorb heat properly, so supply air runs 15 to 20 degrees colder than return air. That’s measurable with an infrared thermometer, and we check it after every coil cleaning so you can see the difference in real numbers.
AC Duct Cleaning
AC Duct Cleaning targets the supply and return ductwork that carries conditioned air from your air handler to each room and back again. Over time, those ducts collect dust, pet dander, and in some Marietta homes, evidence of rodents or old renovation debris. We connect a Nikro HEPA-filtered negative-air machine to the system, seal each register, and use a Rotobrush rotary brush to agitate the duct walls while the vacuum captures everything at the point of contact. AC duct cleaning in a typical Marietta home runs $300 – $550 depending on the number of returns and linear feet of ductwork.
Negative-Pressure Extraction
That term means the vacuum creates a constant pull so loosened debris goes straight into the HEPA filter, not back into your living room. It’s the industry-standard approach for a reason, and it’s the only method we use.
What You’ll See Afterward
We photograph the inside of several ducts before and after, especially problem areas like returns near the floor in high-traffic rooms. You see the exact surfaces we cleaned, not a stock photo from a brochure.
Furnace Cleaning
Furnace Cleaning is the heating-season counterpart to AC cleaning: the burners, heat exchanger, blower assembly, and interior cabinet of your furnace get cleared of soot, dust, and debris so the unit runs safely and efficiently. Most Marietta homes use natural gas furnaces, and a clogged burner or dirty flame sensor is the top reason for no-heat calls in December. Furnace cleaning through Cardinal Air Duct Marietta runs $200 – $400 depending on unit age and access, and it pairs naturally with a full HVAC Cleaning in Acworth visit if you’re treating both sides of the system. We inspect the heat exchanger visually and with a combustion analyzer where applicable.
Combustion Safety Checks
A furnace that burns dirty produces carbon monoxide, and you can’t see or smell it. We inspect the burner flames and check for any gas leaks at the manifold, because heating season in Georgia is short, which means problems sit dormant for eight months before showing up.
Flame Sensor and Ignition
Most “furnace won’t stay lit” calls trace back to a dirty flame sensor. Cleaning it takes ten minutes and restores reliable ignition. It’s a small service that saves you a cold night and a costly emergency visit.
AC Vent Cleaning
AC Vent Cleaning covers the visible registers and grilles in each room: the metal or plastic covers that direct air into your space. These get coated with dust, hair, and sometimes years of paint overspray. We remove each vent, clean it thoroughly, and wipe down the register boot behind it. Standalone AC vent cleaning for an average Marietta home (10 to 15 vents) runs $75 – $150, and it’s included in any full-system cleaning. It’s the part of the job you can actually see the moment we’re done.
Register and Boot Detailing
Dust doesn’t just sit on top of the vent; it cakes inside the boot, the metal transition that connects the register to the duct. We brush and vacuum each boot so the air passing over it isn’t picking up new particles on the way into your room.
Airflow Direction and Balance
As we clean, we check that each vent is open and aimed correctly. In two-story Marietta homes, badly aimed upstairs vents are a major reason the bedrooms never cool evenly. A simple adjustment often fixes the temperature gap between floors.
Furnace Duct Cleaning
Furnace Duct Cleaning is the same ductwork we clean on the AC side, but with attention to the particles that accumulate during heating months: soot, dust burned onto the heat exchanger, and fine lint from blankets and winter clothing. Many HVAC contractors in Marietta will clean AC ducts and skip straight past the furnace side, which is a mistake. We clean supply and return ducts the same way year-round with our Nikro HEPA negative-air system, and pricing runs $300 – $550 for a typical single-family home. If you’re already scheduling furnace cleaning, bundling furnace duct cleaning gets you a better total price.
What Heating Kicks Up
The heat cycle dries out dust that absorbed humidity all summer, turning it light and airborne. That’s why your house gets dustier in winter even with windows closed. Removing the reservoir of dust in the ducts is the only fix that lasts more than a week.
Seasonal Scheduling Logic
Late fall is the smart window: after the AC season ends but before you’re relying on heat daily. You get clean ducts for the season you’re inside most, and the system isn’t fighting Georgia pollen from the spring.
Brands We Service
We work on all major HVAC brands in Marietta homes, including Trane, Carrier, Lennox, Goodman, Rheem, and Daikin. The cleaning process is largely brand-independent, but access panels, coil locations, and blower configurations vary by manufacturer, and our technicians have spent enough time inside each to know exactly what they’re looking at before they start.
Our toolkit includes Abatement Technologies containment equipment for homes with serious contamination concerns, plus Honeywell and Aprilaire filtration products that keep cleaned systems cleaner longer. Whether you have a builder-grade Goodman from the early 2000s or a high-efficiency Trane from last year, we can service it.

AfterSigns You Need a Pro Right Now
- Rooms stay musty even after cleaning. That smell is typically coming from the evaporator coil or duct interior, not your floors or upholstery. Recirculated air carries the odor through the whole house, and no amount of surface cleaning touches it.
- Dust returns within days of wiping surfaces. If you dust on Sunday and see a film by Wednesday, your ducts are likely the reservoir feeding it. Clean ducts mean visibly less dust within two weeks.
- Your energy bill keeps climbing. A restricted evaporator coil and clogged blower wheel force your system to run longer for the same cooling. Utility costs rise steadily even when your usage habits haven’t changed.
- You hear whistling or rattling from vents. Whistling points to restricted airflow, usually from a dirty coil or closed-off duct. Rattling can mean debris inside the ductwork, loose boots, or a blower wheel out of balance.
- Nobody in the home remembers the last cleaning. If the answer to “when did we last have the system cleaned?” is a shrug, you’re overdue. HVAC systems in Marietta should be cleaned every 3 to 5 years, more often with pets.
Our Process, Step by Step
- 1
Inspection and written quote. We walk the system with you, check the air handler, returns, and a sample of ducts, then hand you a written price for the entire job before any equipment comes off the truck.
- 2
Equipment setup and floor protection. We lay drop cloths from the entry to the mechanical room, connect our negative-air machine, and seal the system so debris can only exit through the HEPA filter.
- 3
Mechanical agitation of the ductwork. A Rotobrush rotary brush spins through each duct run to break the mechanical bond of dust and debris on the walls. The vacuum runs continuously, pulling everything out at the point of contact.
- 4
Component cleaning. The evaporator coil, blower wheel, drain pan, condensate line, and burners (if on the furnace side) get cleaned by hand with the right tools for each surface. We also clean every vent cover and boot.
- 5
Verification and documentation. We photograph the coil, blower, and representative duct interiors before and after, confirm airflow at several vents, and walk you through the after photos. You approve the work before we pack up.
How Much Does HVAC Cleaning Cost in Marietta?
A full HVAC cleaning for a typical Marietta single-family home runs $500 – $900, while Kennesaw HVAC Cleaning follows the same pricing structure. That includes the evaporator coil, blower assembly, supply and return plenums, all accessible ductwork, and every vent register. Standalone services cost less: AC coil cleaning runs $150 – $300, furnace cleaning $200 – $400, and AC duct cleaning alone $300 – $550. The final number depends on the size of your home, how many systems you have, how accessible the air handler is, and how long it’s been since the last cleaning. Two-story homes and crawlspace systems add labor time, so they land on the higher end.
The biggest factor is neglect. A system cleaned within the last five years cleans up faster than one that’s gone a decade without attention. You can avoid overpaying by getting a written price before work starts, which we provide on every job without exception. If a company quotes you over the phone without seeing the system, that number is a guess. If they refuse to write down the price, walk away. Our free estimate includes the system inspection, airflow check, and a line-item quote you can hold us to.
