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.

HVAC Cleaning in Norcross means pulling years of dust, pet dander, and attic debris out of the ducts and off the coil, and the honest truth is most Gwinnett County homes are overdue for it. We’re Cardinal Air Duct Cleaning, and our HVAC Cleaning team handles everything from evaporator coils to full supply and return duct runs in older Norcross subdivisions where attic humidity makes the problem worse than homeowners expect. You get a written price before we touch a single register, and before-and-after photos of your own ducts. Call (737) 727-2314 for a free estimate and an honest assessment of what your system actually needs.
Why Cardinal Air Duct Cleaning Is Norcross’s Preferred HVAC Cleaning Company
Norcross homeowners call us because we name the price before we start and we prove the work with photographs. No per-vent games, no surprise add-ons once the van is in the driveway. Our technicians are background-checked and uniformed, and they run professional-grade equipment: Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units so loosened debris goes into the vacuum, not back into your living room. Every booking comes with The Relay Standard: a live trackable arrival time, before-and-after photo documentation, and a digital invoice you can pay from your phone.
Omar Haddad leads our Norcross work with a simple rule: if the work isn’t right within 365 days, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it covers every job, not select ones. A live person answers our phone 24/7, so when you call (737) 727-2314 with a question about a musty smell near Jimmy Carter Boulevard or uneven cooling in a Peachtree Corners-adjacent subdivision, you get a human, not a voicemail loop.
Evaporator Coil Cleaning in Norcross
Evaporator Coil Cleaning in Norcross is the single highest-impact service we perform, because the coil is where your AC actually cools the air, and a fouled coil is the most common cause of that musty smell drifting from Norcross registers. Here’s what the job involves: we open the air handler, inspect the coil with a camera, apply a professional-grade cleaning agent, and rinse the coil so condensate flows freely again. In Norcross homes with 1980s-2000s construction, attic heat and humidity mean biological growth can take hold on a coil within two to three years, long before the filter suggests a problem. Expect to pay $280 to $420 for a full evaporator coil cleaning on a standard residential system in Norcross.
Coil Treatment That Lasts
After the coil is clean, we apply a coil treatment to slow future buildup. This matters in Norcross because our summer humidity keeps coils damp for months at a time, and a treated coil resists the biological growth that feeds on that moisture. We stock Aprilaire and Guardsman treatment products locally, so turnaround is fast for Norcross customers.
When We Recommend It
You need this if your AC runs longer than it used to, if upstairs rooms stay warm, or if the air from your vents has a sour or musty smell. If you’re seeing dust on furniture within days of cleaning, the coil is usually the culprit. A dirty coil also means higher summer electric bills.
AC Duct Cleaning in Norcross
AC Duct Cleaning in Norcross addresses the supply and return duct runs that carry conditioned air through your home, and in this part of Gwinnett County those ducts are frequently routed through unconditioned attic space. That routing means the ductwork expands and contracts with attic temperature swings, and any small leak in a connection pulls in hot, dusty attic air along with whatever the insulation is shedding. The process is straightforward: we seal off the system, set up negative pressure with a Nikro HEPA vacuum, run Rotobrush agitation tools through every supply and return run, and then photograph the interior of your ducts so you can see the before-and-after. A standard whole-system AC duct cleaning in Norcross runs $450 to $750 depending on the number of supply runs and the accessibility of the air handler.
Negative-Pressure Extraction Explained
Negative-pressure extraction means the vacuum keeps the entire duct system under continuous suction while the agitation tools loosen debris. The loosened dust, dander, and attic lint go straight into the HEPA-filtered vacuum cannister, not back into the rooms you live in. This is the difference between professional duct cleaning and a truck-mounted shop-vac shortcut.
What You’ll See Afterward
You get before-and-after photographs of your own duct interiors, not stock photos of someone else’s house. If a section of duct remains visibly dirty, we address it before we pack up. That’s the standard, and it’s why the 365-Day Done Right Promise is written into every Norcross job.
Trusted Brands We Service in Norcross
Norcross homes run a mix of equipment, and we service all of it. Whether your system is a Carrier, Trane, Lennox, Goodman, or Rheem, our technicians know the access points and coil configurations for each. We keep Guardsman and Aprilaire filtration products stocked for quick installation, and our Rotobrush and Abatement Technologies equipment handles both flex duct in older Norcross ranches and rigid metal duct in newer subdivision builds. If your system needs a filtration upgrade, we’ll recommend what fits your existing setup and give you the price before ordering anything.
Common HVAC Cleaning Problems We See in Norcross Homes
- Attic-routed duct leaks pulling insulation and dust. In 1980s-2000s Gwinnett County subdivisions, supply ducts often run through unconditioned attic space, and loose connections at boots and collars pull attic air into the system. We find this constantly on homes off Beaver Ruin Road and Singleton Road.
- Fouled evaporator coils and that musty register smell. Norcross summer humidity keeps coils damp, and biological growth takes hold quickly once dust accumulates. The smell comes from the coil, not the ducts, which is why we always clean both.
- Oversized filters that got switched for cheap ones. Many Norcross homeowners don’t realize their system was designed for a specific filter size, and a generic replacement lets debris bypass entirely. We note the correct size and MERV rating during every visit.
- Dryer lint accumulating in the air handler cabinet. In tight Norcross laundry closets, dryer vent runs can leak humid, lint-heavy air into the adjacent mechanical closet, and that lint ends up on the blower and coil of the AC system. We see this frequently in older homes near downtown Norcross.

FAQs About HVAC Cleaning in Norcross
Per system, always. We give you a written price for the whole job before we start, and it does not change at the door. Per-vent pricing is how some local operations balloon a cheap teaser quote into a far larger invoice once the technician counts every register and return in your Norcross home. Call (737) 727-2314 and you’ll get one flat price for your system, no counting games.
Every three to five years for most Norcross homes, and more often if you have shedding pets, recent renovation work, or a run of unusually humid summers. If your return ducts pull from an unconditioned attic with a leaky connection, you’ll need it sooner. We’ll tell you honestly if your system doesn’t need cleaning yet, because we’d rather earn your trust than sell you a service you don’t need.
We seal off the system, set up negative pressure with a HEPA vacuum, run agitation tools through every supply and return run, clean the evaporator coil and blower, and then hand you before-and-after photographs of your own duct interiors. The whole job takes three to five hours on a typical Norcross two-story. You’ll know what we found and what we removed.
No, dryer vent cleaning is a separate service with its own process and equipment. If we spot lint intrusion into your AC system during an HVAC Cleaning, we’ll tell you and quote the dryer vent work separately. Some Norcross laundry closets leak enough humid lint into the mechanical area that both services are worth doing back to back.
We run Rotobrush rotary brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction, and Abatement Technologies containment units for dust control. For filtration and coil treatment, we stock Aprilaire and Guardsman products. No truck-mounted shop-vacs, no homeowner-grade equipment. You’ll know the tech’s name before they arrive, and they’ll know your system.
