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.
Fast, Reliable HVAC Cleaning Across Kennesaw
HVAC cleaning in Kennesaw typically costs $350 – $600 for a whole system and takes 3 – 5 hours for a standard single-family home. That’s one flat price per system, agreed before we start, not a per-vent quote that swells once the technician is inside. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005, and our HVAC Cleaning team works throughout Kennesaw every week. If you’re noticing dust on your registers, a musty smell at startup, or rooms that never hold temperature well, call us at (737) 727-2314 and a live person picks up.
Why Cardinal Air Duct Cleaning Is Kennesaw’s Preferred HVAC Cleaning Company
We’ve cleaned hundreds of systems in Kennesaw, from 1970s ranch homes near downtown to 1990s and 2000s two-stories off Barrett Parkway and Jiles Road. Homeowners here deal with a specific mix of conditions: humid Georgia summers that feed microbial growth in ductwork, pollen seasons that coat coils within weeks, and an aging housing stock where many air handlers are original builder-grade units with undersized returns. Kennesaw customers tell us the same things repeatedly: they want a price that doesn’t change at the door, a technician whose name they know before they open it, and photo proof the work actually happened.
That’s what the Relay Standard delivers on every booking. You get a live trackable arrival time the morning of the job, before-and-after photos of your own ducts, and a digital invoice you can pay from a link. Omar Haddad, who leads our crew, insists on this: if the work isn’t right within 365 days, we come back and correct it at no charge. It’s the 365-Day Done Right Promise, and it covers every job without exception. A live person answers calls 24/7, and every technician is background-checked, uniformed, and running professional equipment, not truck-mounted shop vacs.
AC Vent Cleaning in Kennesaw
AC vent cleaning in Kennesaw is what most homeowners call us about first: visible dust on the supply registers, airborne particles that settle back on furniture within days, and that stale smell when the air kicks on. What a real AC vent cleaning involves here goes past wiping the register covers. We remove and clean each vent, then we clean the supply duct runs, the return side, and the air handler cabinet where the blower sits. A typical whole-home AC vent cleaning in Kennesaw runs $350 – $600 depending on the number of returns and the size of the home. One price, written down before we start, and it doesn’t change.
What the Blower and Evaporator Coil Actually Need
Clean vents with a dirty blower and coil mean the air moving through them is still dirty. The evaporator coil in a Kennesaw home pulls moisture during the humid months, and that wet surface collects dust and organic matter fast. If we clean the vents but leave the coil fouled, the AC runs harder, cools slower, and the dust comes right back. We clean the blower assembly, the coil, and the drain pan as part of the system price.
Signs That It’s Time
If you’ve lived in your Kennesaw home for three years and have never had the ducts opened up, dust accumulation is almost guaranteed. Homes with pets, recent renovations, or living near construction along Barrett Parkway collect more. The strongest signal is dust on the return grille itself; that means air is pulling debris into the system faster than the filter is catching it.
Furnace Duct Cleaning in Kennesaw
Furnace duct cleaning in Kennesaw matters in ways it doesn’t in milder climates: when you run the furnace through January and February, the same ducts that carried Georgia pollen and summer humidity now carry heated air, which bakes whatever debris is sitting in them. If you smell a faint musty odor on the first heating cycle of fall, the return ducts and blower cabinet are the usual culprits. The same whole-system flat price applies: $350 – $600 for most Kennesaw homes, and we cover both the furnace side and the AC side in one visit so you’re not paying twice.
The Heat Exchanger Doesn’t Get “Cleaned” by a Shop Vac
A furnace has components a duct-only cleaning never reaches: the blower wheel, the filter housing, the heat exchanger surface, and the cabinet itself. We clean the blower and the cabinet with HEPA-filtered negative pressure so loosened debris goes straight into the Nikro vacuum, not back into your living room. Heat exchanger cleaning is a delicate part of the job and frankly one most companies skip because it takes time to do properly.
One Visit for Both Systems
Most Kennesaw homes have a shared duct network for heating and cooling, so cleaning both in one visit is the only sensible way to do it. Our pricing is per system, not per vent, and per system means the full network of supply and return ducts, the plenums, the blower cabinet, and the air handler. Come winter, your furnace runs cleaner from the first cycle.
Trusted Brands We Service in Kennesaw
We maintain and clean systems from every major residential brand you’ll see across Kennesaw: Trane, Carrier, Lennox, Rheem, Goodman, and York. Because our crews work Kennesaw weekly, we know which units are common in the Legacy Park, Hickory Grove, and Barrett Greene subdivisions, and we stock filters and coil treatments from Honeywell and Aprilaire that fit them. No waiting on a special-order part for a coil treatment or a Guardsman filtration upgrade when a technician can grab it off the truck on the way to your job.
Common HVAC Cleaning Problems We See in Kennesaw Homes
- Builder-grade air handlers with undersized returns. Homes built between 1985 and 2005, especially in subdivisions off Barrett Parkway, often have returns that pull more debris through the system than properly sized ductwork would. The blower motor works harder, and that means more dust suspended in the air even right after cleaning.
- Debris left at the source, not the vent. A cheap per-vent cleaning wipes register covers and calls it done. The main lint pathway at the air handler and blower motor stays untouched, so within a month or two, the same dust is back on your furniture.
- No negative pressure, no HEPA filtration, no proof. Run a brush through a duct without a proper vacuum pulling air the other way and the dislodged debris re-enters your rooms instead of leaving the house. Kennesaw homeowners should expect a camera inspection and before-and-after photos of their own ducts, not a vague summary of what was done.
- Humidity-fed microbial growth in the coil area. Kennesaw’s summer humidity means the evaporator coil is wet for months at a time. Without coil treatment, that surface becomes a collection point for dust, pollen, and organic material, and that’s what creates the at-startup smell people describe to us as “gym bag.”
Pricing for HVAC Cleaning in Kennesaw, GA
For most single-family homes in Kennesaw, a full HVAC cleaning runs $350 – $600 for the entire system: supply ducts, return ducts, air handler, blower, coil, and drain pan. Larger two-story homes with two systems or very long duct runs can reach $700 – $800. What affects cost is the number of systems in the home, the accessibility of the air handler (attics versus crawlspaces), and the condition of the ductwork when we inspect it. We don’t charge per vent, we don’t have a teaser coupon that becomes a bigger invoice later, and we don’t upsell for filters. You get a written price before any work starts, and estimates are free. Call (737) 727-2314 and ask for Omar directly.

FAQs About HVAC Cleaning in Kennesaw
Every 3 – 5 years is right for most Kennesaw homes. Homes with shedding pets, smokers, recent renovation, or construction nearby (Barrett Parkway’s commercial growth kicks up a lot of dust) may benefit from every 2 – 3 years. If your home has been through a kitchen remodel or new floors, get the ducts inspected right after, because drywall and sawdust settle into ductwork and the blower will keep recirculating it for months. Call (737) 727-2314 for an honest assessment; if your system doesn’t need cleaning, we’ll tell you plainly.
One flat price for the whole system, always. In Kennesaw that’s $350 – $600 for most single-family homes, covering supply and return ducts, plenums, the air handler, blower, coil, and drain pan. We don’t do per-vent pricing because per-vent pricing is exactly how the bait-and-switch happens: a low per-vent number becomes a huge invoice once the technician counts vents and adds “extras.” You’ll see your full price in writing before any work starts. Call (737) 727-2314 for a free estimate and we’ll send you a written quote.
Yes, and that’s the only way we price it. Kennesaw homes share one duct network for heating and cooling, so cleaning both in one visit is standard practice for us, not an add-on. One system price covers the full network: vents, ducts, air handler, blower, coil, and the furnace cabinet. Most jobs take 3 – 5 hours depending on home size, and you’ll have before-and-after photos of your own ducts before we leave.
Look for three things: written pricing before work starts, before-and-after photos of your actual ducts, and negative-pressure cleaning with HEPA filtration rather than a shop-vac approach. A camera inspection is also non-negotiable; without one, you can’t verify the work was done to NADCA standards. That’s the exact standard we work to at Cardinal Air Duct Cleaning, and the 365-Day Done Right Promise means if anything isn’t right within a year, we return and correct it at no charge.
We don’t promise same-day service, because a real HVAC cleaning is a scheduled 3 – 5 hour job and we won’t rush it or trim steps to fit a same-day window. What we do offer is a live trackable arrival time the morning of your booking, a written price before we start, and a live person who answers the phone 24/7 to schedule you promptly, usually within a few days. Call (737) 727-2314 to get on the schedule and we’ll give you a firm time.
