AfterFull System Cleaning in Marietta, GA
Full system cleaning means we clean every part of your HVAC air pathway, not just the main trunk lines. In Marietta, that includes the supply and return ducts, all register boxes, the blower motor housing, the evaporator coil, and the plenum. Most homes in our area need this level of cleaning every 3 to 5 years, though pet owners and allergy sufferers in neighborhoods like East Cobb or Whitlock often schedule it more frequently.
At Cardinal Air Duct Marietta, we run a full system cleaning with professional-grade equipment, a written price before we start, and before-and-after photos so you can see exactly what came out. If you want a clear scope and a straight answer on cost, call us at (762) 216-4075. And if you’re still deciding whether your ducts need attention at all, our Air Duct Cleaning in Marietta page breaks down the signs, the process, and what a standard cleaning covers.
When You Need Full System Cleaning
Some homes in Marietta get by with a basic Air Duct Cleaning. Others need the full system done. Here’s how to tell the difference:
- Dust returns within days of cleaning surfaces. When the blower kicks on, it pushes dust through every register in the house. If you dust on Monday and see a film by Thursday, the ducts are feeding it back into your rooms.
- One or more rooms never seem to reach the thermostat temperature. Blocked return ducts or a clogged evaporator coil reduce airflow, and in Marietta’s humid summers that imbalance gets uncomfortable fast.
- You moved into a home that was renovated. Drywall dust, sawdust, and paint overspray settle deep in the ductwork during construction. A standard cleaning misses the coil and blower housing where that fine powder packs in.
- Anyone in the home has year-round allergies or asthma. Pollen season in Cobb County runs long, and mold spores thrive in ductwork that stays damp from our summer humidity. Cleaning the full system removes the reservoir, not just the surface layer.
- Your energy bills have climbed without a clear reason. A dirty blower motor and clogged coil force the system to run longer to hit the same temperature. Full system cleaning restores airflow and reduces that strain.
- You can see dust or debris at the register openings. If the visible part of the vent looks dirty, the hidden part is worse. Register boxes collect whatever the ducts push toward them.
Our Full System Cleaning Process
We follow a set sequence on every full system cleaning job in Marietta. You’ll know the steps before we begin, and you’ll see photo proof of the work when we’re finished.
- Walkthrough and written price. The technician inspects the air handler, the return, the supply trunk lines, and a sample of registers. You get a written price before any equipment comes off the truck. That price does not change at the door.
- Access and containment. We cut clean access ports into the main trunk lines and seal off the system. Negative-pressure extraction, which means the loosened debris goes straight into the vacuum instead of back into your living room, keeps the work contained.
- Register and return cleaning. Every register cover comes off, gets wiped down, and the register box behind it is vacuumed. Returns get the same treatment, since returns pull air in and trap the most debris.
- Rotary brush agitation and HEPA extraction. A Rotobrush rotary brush system spins through the ducts to break debris loose while a Nikro HEPA vacuum pulls it out at the same time. Nikro filters run at HEPA standard, meaning they capture particles down to 0.3 microns.
- Air handler, blower, and coil cleaning. This is the step most duct cleaners skip. We open the air handler cabinet, clean the blower motor housing and fan blades, and clean the evaporator coil. In Marietta’s humidity, coil cleaning matters more than almost anything else. A damp, dirty coil grows biofilm and reduces cooling efficiency.
- Filter check and finished report. We confirm your filter size, note its condition, and recommend a replacement schedule. Then we walk you through before-and-after photos on the spot and email you a link to the digital invoice.
Full System Cleaning Pricing in Marietta
A full system cleaning for a typical single-family home in Marietta generally runs between $550 and $950. Smaller homes, condos, and townhomes in areas like Vinings or Sandy Springs border often land closer to $450 to $650. Larger homes with two air handlers or extensive duct runs can push past $1,000. We give you the exact number before we start, in writing, so there’s no guesswork.
What affects the price:
- Number of air handlers. A single system is standard. Two systems, common in larger Cobb County homes, add labor and time.
- Number of registers and returns. More openings mean more time at each one. A typical Marietta home has 8 to 14 supply registers and 1 to 3 returns.
- Coil condition. If the evaporator coil hasn’t been cleaned in years, it takes longer to clean properly. We don’t cut corners here; a dirty coil defeats the purpose of the whole job.
- Access to the air handler. Some attics in older Marietta homes are tight, especially in neighborhoods like historic Marietta Square with original build geometry. Crawlspace units add time too.
- Ductwork condition. Damaged or collapsed sections of flex duct discovered during the walkthrough get flagged separately. You’ll approve any additional work before we proceed.
Every full system cleaning includes a free estimate. Call (762) 216-4075 and we’ll schedule a walkthrough at a time that works for you. You’ll get the written price before any work begins, and it holds.
What’s the difference between a standard duct cleaning and full system cleaning?
A standard duct cleaning covers the main trunk lines, branch runs, and register boxes. Full system cleaning goes further: it includes the blower motor housing, the evaporator coil, the plenum, and the air handler cabinet. Those components sit in the airstream and collect debris just like the ducts do. If you only clean the ducts and skip the coil, you’re leaving a major source of dust and inefficiency untouched. We recommend full system cleaning for most Marietta homes because our region’s heat and humidity make coil cleaning essential for real Residential Duct Cleaning results. Call (762) 216-4075 and we’ll tell you which scope fits your system and your budget.
How often should a full system cleaning be done in Marietta?
Every 3 to 5 years is the right interval for most homes in Marietta. Factors that shorten that window include pets that shed heavily, smokers in the home, recent renovation work, and homes near high-pollen areas like Kennesaw Mountain’s tree cover or the Chattahoochee River corridor. Homes with allergy sufferers or infants should lean toward every 3 years. We track service dates for you, and a quick call to (762) 216-4075 gets you on the schedule whenever you’re due.
Is full system cleaning worth the cost if I already change my filter regularly?
Yes, because a filter only catches what passes through it before it reaches the blower and coil. Debris settles onto the coil and housing regardless of how diligent you are with filters. In Marietta’s climate, that settled material holds moisture and reduces heat transfer, which raises your cooling costs and shortens equipment life. A full system cleaning removes what the filter never sees. For a free estimate on your specific system, call (762) 216-4075.
FAQs – Full System Cleaning
Do you clean the blower motor and evaporator coil as part of full system cleaning?
Yes. Full system cleaning at Cardinal Air Duct Marietta includes the blower motor housing, fan blades, evaporator coil, plenum, and air handler cabinet. These components sit directly in the airstream and collect the same dust and debris as the ductwork, but many companies skip them entirely. We clean them because skipping them leaves the job half done. Every full system cleaning is backed by the 365-Day Done Right Promise: if the work isn’t right within 365 days, we return and correct it at no charge. Call (762) 216-4075 to schedule a walkthrough.
How long does a full system cleaning take in Marietta?
A typical full system cleaning takes 4 to 6 hours for a single-family home with one air handler. Larger homes with two systems, or homes with heavily soiled coils, can take a full day. You’ll know the time estimate upfront when we give you the written price. We don’t rush and we don’t cut corners; the work takes what it takes. Call (762) 216-4075 and we’ll give you a realistic window for your specific home.
Will full system cleaning help with my energy bills?
In most cases, yes. When the evaporator coil and blower motor are caked with dust and biofilm, the system works harder to push air through the house. That means longer run times and higher bills. Cleaning the coil and blower restores airflow and heat transfer, which helps the system run closer to its rated efficiency. The improvement depends on how dirty the system was to begin with, but Marietta homeowners in neighborhoods like Powers Ferry and Terrell Mill see measurable drops during peak summer months. For a free estimate and an honest assessment of your system’s condition, call (762) 216-4075.
Is full system cleaning safe for my HVAC equipment?
Yes, when done correctly. We use Rotary brush agitation paired with negative-pressure extraction, which means the debris we loosen gets pulled directly into a Nikro HEPA vacuum instead of blowing back through the system. The equipment we use is designed specifically for HVAC cleaning, not adapted from other trades. We also take care to protect the air handler components we’re cleaning. Every job is covered by the 365-Day Done Right Promise, so if anything isn’t right, we come back and make it right at no charge. To ask about your system specifically, call (762) 216-4075.
If you’re ready to book a full system cleaning in Marietta, call (762) 216-4075 today. We’ll schedule a walkthrough, give you a written price before any work starts, and send you before-and-after photos so you can see exactly what was removed. Estimates are free, and the price never changes at the door.
