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 Woodstock
HVAC cleaning in Woodstock typically runs $350 – $650 for a standard single-system home, takes 2 – 4 hours, and should include the full air path: supply ducts, return ducts, evaporator coil, blower motor, and air handler. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and we serve every corner of Woodstock from Towne Lake to Downtown and up through Eagle Watch. Our crews know the flex-duct attics, the afternoon I-575 traffic, and the Cherokee County humidity that makes coil and blower cleaning genuinely necessary here. Call (737) 727-2314 for a written, flat price before any work begins.
Why Cardinal Air Duct Cleaning Is Woodstock’s Preferred HVAC Cleaning Company
We built our name in Woodstock on one simple promise: a written price per system before we touch a single vent. No per-vent arithmetic at the door. No “your coil looks worse than we thought” upsell. The price you approve is the price on the invoice, and it doesn’t change when the technician arrives. Omar Haddad, who leads our Woodstock HVAC cleaning work, insists on that standard because he’s seen too many homeowners off Towne Lake Parkway and Ridgewalk get burned by bait-and-switch quotes.
Every job is backed by the 365-Day Done Right Promise. If the work isn’t right within a full year, we come back and correct it at no charge. That’s not a limited offer for select jobs. It covers every booking. Our HVAC Cleaning team also operates under The Relay Standard: a live trackable arrival window, a background-checked uniformed technician whose name you get before they arrive, before-and-after photo documentation, and a digital invoice payable from your phone. Calls are answered by a live person 24/7, so when you need an answer about your system in Woodstock, you don’t leave a voicemail and hope.
AC Coil Cleaning in Woodstock
AC coil cleaning in Woodstock is the single highest-impact service we do here, because Cherokee County summers push evaporator coils to run for months without rest. When the coil is coated in dust, pet hair, and mildew, the system can’t transfer heat efficiently. That means longer runtimes, higher Georgia Power bills, and a compressor that wears out years early. A coil cleaning in Woodstock runs $150 – $300 depending on access and how badly it’s fouled, and we include it in any full-system HVAC cleaning.
Evaporator Coil Cleaning
The evaporator coil sits above or beside your furnace, pulling heat out of the air. In Woodstock homes with pets or with windows open during pollen season, this coil becomes a damp, sticky mat. We clean it with professional-grade coil treatments, not household spray, because the fins are delicate and the wrong chemical corrodes aluminum.
Condenser Coil Cleaning
The condenser coil is the one outside. It collects grass clippings, cottonwood fibers, and the fine red Georgia clay dust that drifts through Cherokee County. We flush it with a low-pressure wash and straighten bent fins, which restores the heat rejection your system depends on through July and August.
AC Cleaning in Woodstock
AC cleaning in Woodstock means cleaning the entire air-moving chain, not just the visible vents. In a typical Woodstock home built in the 1990s or 2000s, we’re cleaning supply and return ducts, the air handler cabinet, the blower wheel and blower motor, and both coils. A complete AC cleaning for a standard Woodstock home runs $350 – $650. That’s one flat price per system, agreed in writing before we start.
Blower Motor and Wheel Cleaning
The blower wheel is the part most companies skip. It sits inside the air handler and spins thousands of times a day, collecting a fine layer of dust that unbalances the wheel and strains the motor. We remove the blower assembly, clean it with agitation brushes, and verify the motor is running at the right amperage before we put it back.
Air Handler and Heat Exchanger Cleaning
The air handler cabinet is where dust, moisture, and Fiberglass shedding collect. In Woodstock attics, the air handler often sits in unconditioned space, so it sees condensation cycles every cooling season. We clean the cabinet interior, the drain pan, and the drain line. When we’re in a gas furnace, we also clean the heat exchanger to restore its ability to shed heat safely and efficiently.
Trusted Brands We Service in Woodstock
We work on all major equipment in Cherokee County homes. Trane, Carrier, Goodman, Lennox, Rheem, Daikin, Amana, American Standard, York, and Bryant are the brands we see most often off Sixes Road, Holly Springs Parkway, and in the subdivisions around Woodstock High School. Because our crews carry Rotobrush rotary brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units, we service every major furnace and air handler brand without needing to send someone back for parts. If your system is an oddball brand or an older model, we’ll tell you before we start what that means for the job. And if you need filtration, we stock Honeywell, Aprilaire, and Guardsman products locally, so the right filter goes in the same day.
Common HVAC Cleaning Problems We See in Woodstock Homes
- Moldy flex-duct in attic runs. Woodstock’s mix of 1990s – 2000s subdivisions and older downtown homes means many systems still run on original flex-duct with loose-jointed R-4 insulation. Cherokee County humidity condenses on those joints, and we regularly find mold growth inside the flex before any register looks visibly dirty.
- Crushed return ducts behind coils. When additions get made or a water heater gets replaced, return flex often gets crushed against a wall or truss. Homeowners notice weak airflow upstairs and call us thinking the system is dying. Often it’s a crushed flex run, and fixing it restores full airflow immediately.
- Dirty blower wheels on PSC motors. Many original Woodstock air handlers have PSC blower motors that have never been pulled. A caked blower wheel means less airflow across the coil, which means longer runtime and occasional freeze-ups. Cleaning the wheel usually fixes the complaint without a motor replacement.
- Clogged drain lines causing water damage. When the air handler sits in an attic, a clogged condensate drain doesn’t just drip, it can damage ceiling drywall. We clear the drain line and pan on every AC cleaning in Woodstock, and we check it before we leave.
Pricing for HVAC Cleaning in Woodstock, GA
Let’s be plain about money. A full HVAC cleaning in Woodstock for a standard single-system home runs $350 – $650. Standalone coil cleaning runs $150 – $300. Blower-only cleaning is $100 – $180. Those prices are per system, not per vent. We don’t quote per vent, because it inflates the invoice on a Woodstock home with 15 – 20 registers. The price you approve before we begin is the price on the final invoice. The main things that affect cost are system size, accessibility (attics with tight clearances cost more than closets), and how long it’s been since the last cleaning. Call (737) 727-2314 and we’ll give you a firm written number before we schedule anything.

FAQs About HVAC Cleaning in Woodstock
Every 3 – 5 years for most Woodstock homes, and more often if you have pets, high-shedding occupants, or you’ve recently renovated. Homes closer to Highway 92 and Towne Lake Parkway often need it sooner because construction dust and traffic particulates get pulled into returns. The honest answer is: if you haven’t had it done since you moved in, and the system predates y’all living there, it’s time. Call (737) 727-2314 and we’ll give you an honest assessment, not a sales script.
Per system, always. Woodstock homes have 15 – 20 registers, and charging $30 – $50 per vent turns a $450 job into a $900 one. We quote one flat price per system before any work begins, and that’s the number on your invoice. No per-vent arithmetic, no hidden add-ons, no door-price changes.
It can help, but it’s not a cure. Cleaning removes accumulated dust, pollen, and pet dander that recirculates every time your system runs, and when paired with a good filtration upgrade like an Aprilaire or Guardsman filter, most Woodstock allergy sufferers notice the difference within a week or two. But if the pollen outside is intense, you’ll still need to keep windows closed and change filters on schedule. We’ll install the right filtration for your system and tell you what to expect.
We clean supply ducts, return ducts, the evaporator coil, the condenser coil (in a standard AC cleaning), the blower wheel and blower motor, the air handler cabinet, the drain pan, and the drain line. That’s the entire air-moving path. Companies that only clean the visible ducts are doing half the job, and within a few weeks the ductwork re-contaminates from the dirty coil and blower. We clean every component in one visit.
No, and neither should anyone else. A real HVAC cleaning takes 2 – 4 hours per system plus travel time, and Woodstock sits on the I-575 corridor where afternoon traffic can add 30 minutes just getting from Towne Lake to Sixes Road. Anyone promising a same-day slot is either cutting corners or not planning to show up. We’ll give you a live trackable arrival window and we keep it. Call (737) 727-2314 for a free estimate and the next available window.
If your Woodstock home’s system hasn’t been cleaned in years, or if one room never cools properly, or if the vents smell musty when the AC cycles on, we can fix that. Call (737) 727-2314 and you’ll speak to a live person, get a written flat price before any work starts, and see before-and-after photos of your own ducts when we’re done. That’s the entire offer. No fine print beyond the 365-Day Done Right Promise: if it’s not right within a year, we return and make it right at no charge.
