Full System Cleaning in Marietta, GA

Full System Cleaning in Marietta, GA

Full system cleaning means we clean every part of your forced-air HVAC system, not just the main trunk lines: supply ducts, return ducts, the air handler, blower motor, evaporator coil, and all vent registers. In Marietta, where pollen from spring oaks and pines mixes with summer humidity and fall leaf dust, a full system clean typically takes 3 to 5 hours and costs between $450 and $850 for most homes. You can reach us at (762) 533-6494 any time to get a written price for your specific house.

This is the most thorough service we offer under our Air Duct Cleaning in Marietta work, and it’s the right call when more than just the ductwork needs attention. Kestrel Air Duct Marietta has been doing this since 2004 under the Kingswell Guarantee, which means the price you’re quoted in writing is the price you pay, and the work is backed in writing for a full year.

When You Need Full System Cleaning

Most Marietta homeowners call us for full system cleaning when a standard Air Duct Cleaning services wouldn’t go far enough. If any of these situations sound familiar, you’re probably in full system territory:

• Dust returns within days of cleaning surfaces. When the blower motor and coil are coated, they re-contaminate the ducts within hours of a basic cleaning. In homes near Kennesaw Mountain, we see this constantly because of the fine trail dust that works its way indoors.
• Cooling bills creep up with no other explanation. A coil with even an eighth-inch of grime loses heat-exchange efficiency. In Marietta’s July heat, that means longer run times and a system that works harder than it should.
• You bought a home built before 2000 and the ducts have never been fully serviced. Construction debris, drywall dust, and sometimes remnants from renovation work sit in the return side of older systems. We find this routinely in East Cobb ranch homes and split-levels from the 1970s and 1980s.
• Someone in the house has year-round allergies or respiratory sensitivity. Marietta’s pollen season runs from February through May, but if symptoms don’t lift when pollen counts drop, the trigger is likely inside the system, not outside.
• You can see dust on the vent louvers, or hear debris rattling in the ductwork. That’s the visible part of what’s accumulated. The coil and blower typically hold far more than the registers show.
• Your last “duct cleaning” used a portable vacuum and took under an hour. A full system clean requires professional negative-pressure equipment and time. If someone was in and out in 45 minutes, they didn’t touch the coil, the blower, or the return side.

Our Full System Cleaning Process

Here’s exactly what happens when a Kestrel technician does a full system cleaning in your home. Every step is spelled out because you should know what you’re paying for before the work starts, not after.

1. Walkthrough and written price. Before anything is touched, we inspect your system, measure the duct runs, check coil and blower access, and hand you a written price. That number doesn’t change at the door or after the work starts. It’s the Kingswell Way: say the price first.
2. System protection and access. We lay down corner guards and drop cloths, open the supply and return plenums, and seal off each register with temporary covers. Your floors and furniture stay clean, and the system is set up for controlled extraction.
3. Brush agitation of the duct walls. We run a Rotobrush rotary brush system through every supply and return line. The rotating bristles dislodge the packed-on dust layer at the duct wall, which is what a vacuum alone can’t do.
4. Negative-air extraction. A Nikro negative-pressure unit hooks to the system and pulls everything the brush loosens out of the ductwork and into a filtered collection chamber. Negative-air extraction just means the air pressure inside the ducts is kept lower than the room, so debris is pulled out rather than blown around your house.
5. Coil and blower cleaning. This is the step basic duct cleanings skip. We access the evaporator coil and blower motor, then clean both with the same extraction running. A clean coil and blower are what keep the system from re-contaminating the ducts within weeks.
6. Final walkthrough and written guarantee. We show you the collection canister, walk you through what came out, and hand you the written 365-Day Done Right Promise. If anything falls short within the year, call us and we return at no charge.

For homes where air quality is a concern, we also offer Honeywell, Aprilaire, and Abatement Technologies HEPA filtration products that work between cleanings. We’ll mention them if they’re relevant to your home, and never push them when they’re not.

Full System Cleaning Pricing in Marietta

Full system cleaning in Marietta runs between $450 and $850 for most homes. The price you get depends on four things: the square footage of the house, the number of supply and return runs, whether the coil and blower are easy to access, and how long it’s been since the system was last cleaned. You always get the exact number in writing before we start.

Here’s how pricing typically breaks down:

• Smaller homes (1,200 to 1,800 square feet): $450 to $600, typically a single system with 8 to 12 supply runs and an attic or closet air handler.
• Mid-size homes (1,800 to 2,800 square feet): $550 to $750, usually one system with 12 to 18 runs or two smaller systems with moderate coil access.
• Larger homes (2,800 to 4,000 square feet): $700 to $850, often two systems or a single system with long runs and a tight coil access in a crawlspace or attic.

What can push the price toward the top of a range: an evaporator coil that requires working in a tight attic under July heat, a return chase packed with decades of dust, or systems that haven’t been serviced in 15 years. None of this is a surprise upcharge. We account for all of it in the written quote before we start, and estimates are always free.

If you’re comparing prices, ask the other company one question: does the quote include the coil and blower? Many low-cost duct cleanings only do the branch lines, and the dust comes back within a month. A full system clean is more work, which is why it costs more than a $99 special, and why it actually solves the problem.

Why the Coil and Blower Matter in Marietta

Humidity is the variable most people underestimate. Marietta’s spring and summer moisture means the evaporator coil is wet for months at a time. Wet coils catch dust like a damp cloth. That dust layer becomes a paste, then hardens, and it inhibits cooling and feeds mold growth in the drain pan.

We regularly pull coils in Marietta homes that have a quarter-inch of compacted lint and dust on the air-entry side. The homeowner wonders why the AC runs constantly and the upstairs never cools. The fix isn’t more refrigerant, it’s removing the blanket off the coil. That’s not something a brush-down-the-vent cleaning accomplishes.

The blower motor is the other piece. A dusty blower wheel is out of balance, which wears the motor bearings and pushes less air. We clean the wheel and motor housing as part of every full system service, using extraction so the dislodged dust goes into the machine, not into your bedrooms.

How Full System Cleaning Differs from a Basic Duct Cleaning

A basic duct cleaning addresses the supply and return lines. It removes built-up dust and debris from the air pathways, which is valuable on its own. What it doesn’t do is address the components that generate and recirculate that dust in the first place.

A full system cleaning includes everything a duct cleaning does, plus the air handler, evaporator coil, blower motor, and blower wheel. We also clean the return-side ducting thoroughly, which is where Marietta homes collect a lot of fine dust from the constant cycle of open windows in spring and fall.

Think of it this way: if you wash your car’s body but never the engine bay, the exterior looks fine for a while. But the engine is still coated. Your HVAC system is the same. The coil and blower are the engine. Full system cleaning addresses the entire machine, not just the visible surfaces.

Equipment That Does More Than a Shop Vac

The equipment matters because the job is deeper than what a handheld vacuum can reach. We use professional-grade tools for a reason.

Rotobrush rotary brush systems send a spinning brush down every duct run. The bristles beat against the duct wall to break up the packed dust layer, which most systems have after even a few years. That mechanical agitation is the difference between a surface pass and an actual removal.

Nikro negative-pressure units create suction at the system level, pulling dislodged contaminants out through a sealed filtration chamber. The negative pressure keeps dust from escaping into your living room while the brush works. This is professional extraction, not a big vacuum hose attached to a truck.

And for homes that want ongoing air-quality management between cleanings, we can install Honeywell, Aprilaire, or Abatement Technologies filtration products. The Abatement Technologies HEPA units are particularly effective for homes near high-pollen corridors in Marietta, where spring brings a visible dusting of yellow onto every surface.

The 365-Day Done Right Promise, in Plain Terms

Every full system cleaning from Kestrel Air Duct Marietta comes with a written guarantee we call the 365-Day Done Right Promise. Here’s how it actually works, because a guarantee should never be vague.

If the work we performed falls short within 365 days of service, call us and describe the issue. We’ll schedule a return visit at a time that works for you, and we’ll make the work right at no charge. You don’t need to keep the original invoice, though it helps. You don’t need to argue a case. If the cleaning didn’t hold, we come back.

This isn’t a promotional offer or a limited-time guarantee. It’s been the standing policy since the company was founded in 2004, and it’s written into every job we do. Dale Whitmore holds every technician to the same standard: if it’s not done right, we make it right.

What qualifies: dust re-accumulation in the ducts to a point that matches or exceeds the day we cleaned, a coil or blower that shows visible buildup within the year, or any part of the system we serviced that fails to stay clean through normal use. What doesn’t qualify: new construction dust from a renovation that happened after our visit, or significant new duct damage from animals or water intrusion. If you’re not sure, call. We’ll tell you straight.

The Kingswell Way on Every Job

When a Kestrel technician arrives at your Marietta home, the visit follows a code we call the Kingswell Way. It’s not a mission statement on a website. It’s a checklist that governs how the work is done.

• Say the price. The written quote is in your hand before a single vent is opened.
• Show up in the window we gave. You get a defined arrival window, and we keep it. If something changes, a live person calls you.
• Leave the place cleaner. Drop cloths, corner guards, and a final sweep of the work area. The only thing we leave behind is a cleaner system.
• Put the guarantee in writing. The 365-Day Done Right Promise is handed to you on paper, not just referenced in passing.
• Come back if it fails. If the work falls short within the year, the return visit is free. Full stop.

Every Kestrel technician is background-checked and uniformed. The person walking into your home has been vetted, trained on the equipment, and operates under the same written standards that have been in place since 2004.

FAQs – Full System Cleaning

How much does full system air duct cleaning cost in Marietta?

Full system cleaning in Marietta typically costs between $450 and $850, depending on home size, the number of duct runs, and how accessible your coil and blower are. The exact price is always provided in writing before any work begins. Call (762) 533-6494 for a free estimate on your specific home.

How long does full system cleaning take?

Most Marietta homes take between 3 and 5 hours for a complete full system clean. Larger homes with two systems or difficult attic access can run up to 6 hours. We’ll give you a realistic time window when we provide the written quote, and we keep that window.

Is full system cleaning worth it compared to basic duct cleaning?

Full system cleaning is worth it when the coil and blower haven’t been cleaned in years, or when dust returns shortly after a previous duct-only cleaning. If the source of the dust is still dirty, you’re paying to clean the pathways but leaving the engine coating in place. We’ll inspect your system and tell you honestly which service you need, even if it’s the less expensive option.

Will full system cleaning reduce my energy bills in Marietta’s summer heat?

A clean evaporator coil transfers heat far more efficiently than a coated one, which means your system runs less to hit the same temperature. In Marietta’s hot, humid summers, that can translate to measurable savings on peak cooling bills. For exact numbers on what cleaning does for your specific system, call (762) 533-6494 and we’ll walk through what we typically see in homes like yours.

Do you actually clean the coil and blower, or just the ducts?

Yes, full system cleaning includes the evaporator coil, blower motor, blower wheel, and air handler, in addition to every supply and return duct and each register. This is the service’s defining difference. If a company quotes you a “full cleaning” but won’t touch the coil, it’s not a full cleaning, and you should ask exactly what their price includes in writing.
