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 Louisville
HVAC cleaning in Louisville, TN typically runs $380 – $560 for a complete system on a standard single-unit home, and the work usually takes 3 – 5 hours. That covers the supply ducts, return ducts, air handler, blower motor, and evaporator coil as one flat per-system price. We work throughout Blount County, from homes off Topside Road to the neighborhoods around Louisville Point Park. Call (737) 727-2314 for a written quote before any work begins.
Louisville sits in a TVA-served, mixed-humid pocket of Blount County. Homes here commonly run heat pumps nearly year-round, which means the air handler and blower motor cycle almost continuously rather than sitting idle through distinct seasons. The result is continuous low-level filter bypass and light lint buildup, not heavy seasonal debris. That changes how we approach HVAC Cleaning in this area, and it changes what you should expect from a cleaning.
Our crews know Louisville’s housing stock: ranches with long return-side runs, two-story homes with upstairs and downstairs register sets, and utility closets where the air handler shares space with a water heater. We schedule from our Memphis office, but the technicians who show up are local to the Louisville area. A live person answers when you call, and you’ll get a written price before a single duct is touched.
Why Cardinal Air Duct Cleaning Is Louisville’s Preferred HVAC Cleaning Company
Cardinal Air Duct Cleaning operates as part of the Relay Home Co. family, founded in 2005, and every Louisville job runs under the Relay Visibility Guarantee. That means a live trackable arrival window, before-and-after photo documentation of your ducts, and a digital invoice you can pay from a link. No vague estimates, no four-hour arrival windows, no price that shifts once the technician is standing in your hallway.
Our Louisville customers regularly mention the written price and the photos. You know the technician’s name before they open the door, they arrive in uniform, and they’ve passed a background check. The equipment they carry is professional-grade: Rotobrush rotary brush systems, Nikro HEPA-rated vacuums, and Abatement Technologies containment units. Not a truck-mounted shop vac. That distinction matters when you’re paying to remove debris, not just stir it up.
We back every job with the 365-Day Done Right Promise. If the work isn’t right within 365 days, we return and correct it at no charge. That’s the longest-standing satisfaction window in the trade, and it covers every booking without exception. Omar Haddad leads the Cardinal team, and the standard he set is simple: total visibility from booking to invoice.
There’s no per-vent pricing here. No bait-and-switch coupon that turns into a far larger invoice once the van is on the drive. One flat price per system, handed to you in writing before work starts.
AC Vent Cleaning in Louisville
AC vent cleaning in Louisville means removing the dust, pet hair, and light lint that accumulates inside your supply and return registers when a heat pump runs through a Blount County summer. Because Louisville homes run cooling for long stretches, the register faces and the first few feet of duct behind them collect a fine coating faster than in colder climates where systems rest for months.
A typical AC vent cleaning as part of a full-system job runs $150 – $250 in Louisville when done alongside duct cleaning. We clean every supply register, return grille, and the visible duct runs behind them. Your registers come off, get washed, and go back on clean. We photograph each one before and after, so you see exactly what was there.
The Process We Use
We connect a Nikro HEPA vacuum to create negative pressure, meaning loosened debris goes straight into the collection unit, not back into your living room. Then Rotobrush agitation tools run through the supply and return ducts to dislodge the film that’s stuck to the duct walls. The vacuum captures it at the source.
When Louisville Homeowners Call Us
Most calls come from people who’ve noticed dust trails on supply registers, a musty odor when the system kicks on, or visible buildup behind the grilles. Some just bought a home in Louisville and don’t know when the ducts were last touched. If you’re seeing dust within days of dusting your furniture, the vents are usually the source.
Furnace Duct Cleaning in Louisville
Furnace duct cleaning in Louisville matters even though winters here are mild compared to the Midwest. Your heat pump’s air handler moves air through the same ducts in heating mode that it uses in cooling mode, and if those ducts have accumulated dust and lint all summer, the furnace cycle just pushes it through warmer, drier air. That’s when odors get stronger and dust settles harder.
Furnace duct cleaning as a standalone service in Louisville runs $280 – $380 for a typical single-system home. Most homeowners bundle it with the evaporator coil and blower motor cleaning for a single flat per-system price of $380 – $560. That’s the honest math. You get one written price before we start, and it does not change.
What Gets Cleaned
The blower motor compartment, the return-side ducts, the supply-side ducts, and the heat exchanger surfaces we can access. A clean blower wheel moves more air with less strain. A dirty one spins out of balance and pushes less air through your registers, which makes your system run longer to hit the same temperature.
Filter Fit and Blower Health
At a house off Topside Road near Louisville Point Park, our tech found a Honeywell media cabinet whose homeowner had been using a too-small filter. Dust bypassed the frame entirely and went straight into the blower motor compartment. The homeowner had a faint musty odor and visible dust trails on the supply registers. We set up HEPA filtration and negative pressure, ran Rotobrush tools through the supply and return ducts, and photographed every register before and after. Their own duct photos showed the debris band we pulled out.
Trusted Brands We Service in Louisville
We work on equipment from the brands Louisville homes actually have: Honeywell media cabinets, Aprilaire filtration, Guardsman products, and Abatement Technologies containment setups. We carry common filters and replacement media so a service call doesn’t turn into a week-long wait for parts. If your air handler or blower compartment needs a replacement filter frame, we’ll have it on the truck or source it locally within a day or two. You won’t be left waiting on a shipment while your system runs dirty.
Common HVAC Cleaning Problems We See in Louisville Homes
- Continuous blower wear from year-round heat pump use: The blower motor in a Louisville home often runs 3,000+ hours a year. That constant cycling pulls a steady stream of household dust through the return side, and without regular cleaning it packs onto the blower wheel and evaporator coil.
- Filter bypass from ill-fitting aftermarket filters: We see it constantly in Blount County: a filter that’s a half-inch too small, letting air and dust slip around the frame. It’s one of the most common causes of blower motor dust buildup we pull out of Louisville systems.
- Long return ducts in ranch homes collecting ragweed and pollen: Louisville’s mixed-humid climate and surrounding vegetation means pollen seasons stretch long. Ranch homes with long return-side runs collect it in volume. Without source removal, it just cycles back into the house air.
- Per-vent pricing that balloons after the tech counts your registers: Louisville homeowners with sprawling ranches and upstairs/downstairs register sets are prime targets for per-vent pricing. A tech quotes one number over the phone, then counts 14 vents plus returns and the invoice triples. Our price is per system, not per vent.

FAQs About HVAC Cleaning in Louisville
No. Most Louisville homes need HVAC cleaning every 3 – 5 years, not annually. The exception is a home with heavy shedding pets, recent renovation dust, or a smoker in the house. If your system is under three years old and you’ve been changing filters regularly, annual cleaning is almost always unnecessary. We’ll tell you plainly if you don’t need us yet. Call (737) 727-2314 to talk it through.
Pricing is per system, not per vent. A two-story Louisville home with one HVAC system and registers on both floors is still one system: $380 – $560 complete. If you have two separate systems, each is priced as its own system and you’ll see both numbers in writing before we start. No counting registers and multiplying. Call (737) 727-2314 for an exact quote.
Yes. Every job includes before-and-after photos of your ducts and registers, taken by the technician while the work is happening. You’ll see the debris we removed, the clean registers after the job, and the inside of the duct runs we serviced. This is part of the Relay Visibility Guarantee on every Cardinal booking in Louisville.
Yes. Higher MERV ratings, like MERV 11 – 13, catch finer particles and reduce how much dust reaches your blower and evaporator coil. But too high a rating can restrict airflow if your system wasn’t designed for it. In Louisville’s year-round heat pump setups, we usually recommend a MERV 8 – 11 balance for most homes. We’ll check your cabinet size, filter fit, and system static pressure during the job. Call (737) 727-2314 to ask about your specific setup.
Yes, but only because the laundry room often shares air space with the return side of your HVAC system. A clogged dryer vent blows lint into the room, and that airborne lint gets pulled into the HVAC return, then packed into your ducts and blower. We service dryer vents as a separate job, and many Louisville customers bundle it with HVAC cleaning for one visit.
