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.

AfterFast, Reliable HVAC Cleaning Across Alpharetta
HVAC cleaning in Alpharetta means removing years of dust, pollen, and debris from your air handler, evaporator coil, blower, and ductwork so your system actually moves clean air. Most Alpharetta homes need it every 3 to 5 years, though that timeline shifts depending on your house, your filters, and whether you have pets. We serve every corner of Alpharetta, from Windward to the townhomes off Haynes Bridge Road, and we show up with a written price before any work starts. That’s the way it should work. Call (737) 727-2314 and you’ll reach a live person who can walk you through it.
Why Cardinal Air Duct Cleaning Is Alpharetta’s Preferred HVAC Cleaning Company
Alpharetta homeowners call us because we name a price upfront and we don’t change it when the van pulls up. That’s the whole pitch. The 365-Day Done Right Promise backs every job: if the work isn’t right within a year, we return and fix it at no charge. Omar Haddad leads our team, and every technician who knocks on your door in Alpharetta is background-checked, uniformed, and running pro-grade equipment, not a truck-mounted shop vac. That’s a meaningful difference when you’re paying someone to clean inside your walls.
The Relay Standard is what you get when you book with us: a live arrival window you can track from your phone, before-and-after photos of your own ducts, and a digital invoice you can pay with a link. No four-hour windows. No mystery charges. Alpharetta homeowners appreciate that because so many of them have been burned by bait-and-switch duct cleaning coupons before.
We’re part of the Relay Home Co. family, founded in 2005, and we coordinate our Alpharetta scheduling from the brand’s Atlanta office. But the crew that shows up at your door? They’re local, they know the difference between a Windward flex-duct system and a new rigid-metal build near Avalon, and they clean accordingly. That local knowledge shows in the work.
AC Cleaning in Alpharetta
AC Cleaning in Alpharetta is the deepest clean your air conditioning system can get, and it’s the service that makes the biggest difference when your system smells musty or your cooling bill keeps climbing. In this part of Georgia, our air conditioners run hard from May through September. That long season means the evaporator coil and the blower collect Georgia red clay dust, pollen from Alpharetta’s pine canopy, and bits of insulation from your attic. A standard AC Cleaning in Alpharetta runs $250 to $450 depending on system size and access.
When a unit hasn’t been opened in years, the coil can be so packed that airflow drops by 30 percent or more. That’s not an exaggeration; we see it weekly in Alpharetta homes. The fix is methodical: we pull the panel, inspect the coil and blower, and use professional agitation tools paired with HEPA-rated extraction from Nikro. You see the before-and-after photos when we’re done.
What Gets Cleaned
Your blower wheel and housing get the same attention as the coil. A dirty blower wheel throws off balance and makes the motor work harder, which shortens its life. We remove the wheel when the design allows, or we clean it in place with agitation and negative-pressure extraction so the debris goes straight into our vacuum. Not back into your living room.
When A Home Needs It
If you’ve lived in your Alpharetta home for five years and never opened the air handler, you’re due. If someone in the house has year-round allergies or you smell something stale when the system kicks on, that’s also a signal. A system that’s been maintained on schedule usually needs AC Cleaning every 3 to 5 years, not every year.
Evaporator Coil Cleaning in Alpharetta
Evaporator Coil Cleaning in Alpharetta is the single most neglected piece of HVAC maintenance we see, mostly because it’s out of sight. The evaporator coil sits inside your air handler or attached to your furnace, and it’s a magnet for the fine dust that slips past your filter. Over a Georgia summer, that coil gets coated. As the coating builds, the coil loses its ability to pull heat from your home’s air, and the system runs longer to hit the same temperature. A dedicated evaporator coil cleaning in Alpharetta runs $150 to $300 on its own, or it can be added to a full HVAC Cleaning for a reduced combined rate.
Here’s something Alpharetta homeowners should understand: the coil is where the musty-smell problem usually lives. Dust and pollen collect on the coil’s wet surface, and microbial growth follows. You can upgrade to a MERV 13 filter, but if the coil is already fouled, the smell doesn’t go away. The coil has to be cleaned.
The Process We Use
We remove the access panel, inspect the coil with a camera, and then clean it using coil-safe cleaning agents followed by thorough rinsing. If the coil is heavily impacted, we use a HEPA vacuum to pull loosened debris out as we work. For Alpharetta homes with high-efficiency units or units installed in tight attic spaces, this work takes longer than a basic clean, and the price reflects that access difficulty.
What It Fixes
A clean evaporator coil lowers your energy use, reduces strain on the compressor, and kills the musty smell at its source. If your Alpharetta home’s AC runs constantly in July and August, a fouled coil is often the reason. The fix is not a new filter or a bigger unit. It’s a clean coil.
Trusted Brands We Service in Alpharetta
We work on all major equipment in Alpharetta, and we carry common parts for Carrier, Trane, Lennox, Rheem, and Goodman systems, plus Aprilaire filtration and Guardsman treatment products. The tools we use on your system are Rotobrush rotary brush systems and Nikro HEPA vacuums, which are the same brands commercial contractors spec for hospitals and data centers. For Alpharetta customers, that means you get professional-grade extraction that captures dust instead of recirculating it, and we stock the parts locally so we’re not waiting on a distributor when your system needs a fast turnaround.
Common HVAC Cleaning Problems We See in Alpharetta Homes
- Flex duct lint pathways in mid-1990s Windward homes. The flexible ductwork common in those 1990s subdivisions has a ribbed interior that catches and holds debris far more aggressively than rigid metal. If a cleaning contractor treats flex duct the same as metal, the job fails and the debris comes right back.
- Skipped return ducts in two-story foyers. Alpharetta homes with vaulted ceilings and two-story foyers have return ducts that are genuinely hard to access. Contractors skip them because it’s difficult, and that’s exactly why the work doesn’t hold. We go after them with the right equipment, and we photograph the results.
- No camera inspection of the air handler or coil. Too many Alpharetta HVAC Cleanings amount to running a vacuum through the registers. Without a camera inspection of the air handler and evaporator coil, hidden mold and buildup stay exactly where they are. A filter upgrade won’t fix that.
- Weak negative pressure in open-concept floorplans. Newer Alpharetta townhomes and open-concept builds need strong negative-pressure extraction during cleaning, or the job just stirs dust through the whole house. We use Abatement Technologies containment and Nikro HEPA extraction so what we loosen stays captured.
Pricing for HVAC Cleaning in Alpharetta, GA
For a standard single-system home in Alpharetta, a complete HVAC Cleaning runs $350 to $550. That’s one flat price per system, agreed in writing before we start, and it includes the blower, evaporator coil, air handler, and supply and return ductwork. AC Cleaning alone runs $250 to $450, and evaporator coil cleaning as a standalone service runs $150 to $300. Larger homes, double systems, or difficult attic access can push toward the top of those ranges, and we’ll tell you that before we schedule, not after we arrive.

FAQs About HVAC Cleaning in Alpharetta
Every 3 to 5 years for most Alpharetta homes, assuming you’re changing filters regularly and don’t have major construction dust or a pack of shedding dogs. Newer homes with rigid metal ductwork can push toward the 5-year mark. Older Alpharetta homes with 1990s flex duct, heavy pollen exposure, or residents with allergies often need it sooner. Call (737) 727-2314 and we’ll help you figure out where your system falls.
Flat price per system. Always. We don’t do per-vent pricing, and we don’t start with a low teaser number and then pad the invoice when the van is in your driveway. You get a written price for the entire system before any work begins, and that number does not change. Call (737) 727-2314 for a quote specific to your Alpharetta home.
We start with a camera inspection of the air handler, evaporator coil, and ductwork so we both know what’s actually in there. Then we use Rotobrush agitation and Nikro HEPA negative-pressure extraction to pull dust, pollen, and debris out of the system. You get before-and-after photos of your own ducts, not stock images. The price is set before we start, and the work is covered by our 365-Day Done Right Promise. Call (737) 727-2314 to schedule if your system is overdue.
Yes, and in Alpharetta we strongly recommend it. The evaporator coil is where musty smells and airflow restriction usually start, and skipping it means you’re only doing half the job. It can be folded into a full HVAC Cleaning at a reduced combined rate, or done as a standalone service. Call (737) 727-2314 and we’ll price it out for your system.
Not reliably, and we’d rather be honest than promise a time we can’t keep. HVAC Cleaning is a scheduled job that takes several hours when it’s done right, and cutting corners to hit a same-day window means skipping the camera inspection or rushing the negative-pressure work. When you book, you get a live arrival window you can track from your phone, and you’ll know exactly when we’re coming. Call (737) 727-2314 to pick a time that actually works.
Call (737) 727-2314 today for a free, written HVAC cleaning estimate in Alpharetta. You’ll get a flat price, a trackable arrival window, and before-and-after photos of your own system. If the work isn’t right within 365 days, we come back and make it right. That’s the Cardinal standard, and it applies to every Alpharetta job without exception.
