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.

Why Cardinal Air Duct Cleaning Is Lawrenceville’s Preferred HVAC Cleaning Company
Air Duct Cleaning in Lawrenceville starts with homeowners calling us because we give them something most contractors won’t: a written price before the technician touches a single component, and before-and-after photos of their own ducts when the job is done. That’s the Relay Standard, and every booking through Cardinal Air Duct Cleaning includes it, no exceptions. Our technicians are background-checked, arrive in uniform, and you know their name before they ring the doorbell.
Our parent company, Relay Home Co., was founded in 2005, and every independently owned Cardinal location operates under the Relay Visibility Guarantee. For Lawrenceville customers, that means a live trackable arrival window, a digital invoice you can pay from your phone, and a 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. That’s the longest satisfaction window in the trade, and it covers every job, not select ones.
Omar Haddad, the owner behind Cardinal Air Duct Cleaning, built this operation around a simple frustration: homeowners shouldn’t have to guess whether a duct cleaner actually cleaned anything. In Lawrenceville, where most homes run flexible duct runs and single-return layouts, that transparency matters more than anywhere else. You can’t see your coil. You can’t see inside your returns. You should still be able to see the proof.
Key takeaways for Lawrenceville homeowners:
- One flat price per system, agreed in writing before work starts, never per vent.
- Before-and-after photos of your own ducts, taken at the same angles.
- 365-Day Done Right Promise on every job, with a free second visit if any repair fails.
- Live person answers, 24/7, no voicemail loops.
AC Cleaning in Lawrenceville
AC cleaning in Lawrenceville is the most commonly requested HVAC cleaning we do, and for good reason: most homes here were built between 1995 and 2015 with high-efficiency air handlers that pack tight fins and shallow condensate pans. Those systems get grimy fast, especially through Gwinnett’s long, humid summer runs. When your AC cleaning includes the evaporator coil, blower motor, and drain pan, you can expect to pay between $385 and $750 for a single system in Lawrenceville, depending on how much buildup the coil has and whether the blower housing needs full removal to clean properly.
What We Actually Remove
The buildup on a Lawrenceville AC system is mostly biological: a gray-white film of dust, skin cells, and pollen that compresses into a damp mat on the coil fins. We use a negative-pressure extraction setup, which means the loosened debris goes straight into a HEPA-filtered vacuum, not back into your living room. Our techs run a Nikro HEPA vacuum and agitation brushes through the coil, blower wheel, and housing, then treat the coil surfaces.
When It’s Time
If your AC runs constantly without cooling the way it did two summers ago, or if anyone in the house notices allergy symptoms that spike when the system cycles, your coil and blower are probably carrying a load. In Lawrenceville’s subdivisions, where one air handler serves 12 to 18 registers, a dirty coil forces the entire system to work harder and cool less evenly. A camera inspection tells us in minutes whether cleaning will help, and you’ll see that footage yourself.
Evaporator Coil Cleaning in Lawrenceville
Evaporator coil cleaning in Lawrenceville homes typically runs $385 to $650 when done as part of a full HVAC Cleaning job, but it is also available as a focused service. The evaporator coil is the indoor coil that sits inside the air handler and absorbs heat from your home’s air. In Lawrenceville, where summer humidity pushes condensate through the coil constantly, that wet surface is a magnet for the dust that slips past the filter. A matted coil can cut airflow by up to 30 percent, which means higher energy bills and a system that runs longer to hit the same set point.
How Coil Grime Hits Gwinnett Systems
Most Lawrenceville homes run single-return duct layouts with one main return, often in a hallway ceiling. That means all the air entering the system funnels through one filter opening, and whatever that filter misses lands directly on the coil. We regularly pull coils in Lawrenceville that look like they’re wearing a sweater, even in homes where the filter has been changed on schedule. A coil cleaning removes that mat, restores proper airflow, and drops your system’s static pressure back where the manufacturer wants it.
Coil Treatment After Cleaning
After the coil is cleaned, we apply a coil treatment that keeps the aluminum fins from degrading and slows future buildup. If your coil is severely corroded or damaged, we’ll show you the camera footage and tell you honestly whether cleaning is worth it or whether replacement is the smarter call. That written honesty is part of why Lawrenceville homeowners on Lawrenceville service calls keep us on speed dial.
Trusted Brands We Service in Lawrenceville
We work on every major residential HVAC brand installed in Gwinnett County, including Trane, Carrier, Lennox, Rheem, Goodman, and York. Our trucks carry professional-grade cleaning equipment from Nikro, Abatement Technologies, and Rotobrush, and we stock filters and filtration upgrades from Honeywell and Aprilaire for Lawrenceville homeowners who want better air quality after their system is cleaned.

Common HVAC Cleaning Problems We See in Lawrenceville Homes
- Single-return systems with overloaded coils. Most Lawrenceville subdivisions built since the late 1990s use one large central return. One return means one filter catching everything, and when that filter is undersized or dirty, the coil takes the abuse. We see it on nearly every call in neighborhoods like Sweetwater Green and along Old Peachtree Road.
- Flexible duct runs that sag and trap debris. The 1990s and 2000s construction boom in Gwinnett leaned heavily on flex duct. Over time, those runs sag between supports and create low spots where dust and debris pool. That’s debris that gets stirred back into your living space every time the blower kicks on.
- Blower motors caked with fine dust. A blower wheel coated in a baked-on layer of dust moves less air and makes the motor work harder. In Lawrenceville’s humid climate, that dust bonds with moisture and turns into a crust that simple vacuuming won’t budge. We pull the blower motor and clean the wheel properly, not just blast it from the front.
- Cheap previous cleanings that only did the supply vents. We’ve lost track of how many Lawrenceville homeowners have shown us a receipt from a $99 vent cleaning, only for our camera to reveal an untouched coil and blower. Hose-and-go work doesn’t clean the system. It just moves dust around and wastes your money.
Pricing for HVAC Cleaning in Lawrenceville, GA

FAQs About HVAC Cleaning in Lawrenceville
Every 3 to 5 years is realistic for most Lawrenceville homes, and sometimes longer if the system has a good filter and no pets. What pushes that number shorter is the humidity: Lawrenceville’s long, wet summers keep your evaporator coil damp for months at a time, which attracts and holds dust that would otherwise pass through. If you run a high-quality Honeywell or Aprilaire media filter and change it regularly, you may get closer to the 5-year mark. Call (737) 727-2314 and we’ll walk through what’s right for your specific system.
One price per system, always. Per-vent pricing punishes the standard Gwinnett subdivision layout, where a single air handler feeds 12 to 18 registers. That’s how a “cheap” cleaning turns into a $600 surprise once the technician counts registers. We hand you a written price based on the whole system before any work starts, and it does not change at the door.
Yes. Every Cardinal Air Duct Cleaning job in Lawrenceville includes before-and-after photo documentation of your own ducts, taken at the same angles during the camera inspection and again after cleaning. You’ll see the coil before and after, the blower motor before and after, and the return plenum before and after. If the work isn’t right within 365 days, we return and correct it at no charge, and you can call (737) 727-2314 to schedule that return visit.
A proper HVAC cleaning covers far more than ducts. It includes the evaporator coil, blower motor and wheel, blower housing, air handler interior, return plenum, and the supply and return duct runs themselves, all agitated and extracted under negative pressure with HEPA filtration. In Lawrenceville’s flex-duct-dominated subdivisions, the coil and blower are usually the dirtiest components, so skipping them means skipping the actual problem. We don’t skip anything, and we prove it with camera footage.
Because a proper HVAC cleaning in a Lawrenceville single-return system takes real time to do right. A negative pressure setup, full coil and blower disassembly, agitation brushing, HEPA extraction, and camera documentation cannot be rushed into a 45-minute window. We won’t lie to you about speed and then deliver a half-done job. Call (737) 727-2314 and we’ll give you a live arrival window you can track from your phone, so you’ll know exactly when we’re coming.
