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 Maryville’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, which means every booking runs on The Relay Standard: a live trackable arrival window, before-and-after photo documentation, and a digital invoice you can pay from your phone. Maryville homeowners tell us this matters because too many duct cleaning quotes start low and end high. Ours doesn’t. The written price we hand you before work starts is the price you pay. Period.
Our technicians are background-checked and arrive in uniform with their name on the booking. They carry Rotobrush agitation systems and Nikro HEPA-rated vacuums because Maryville’s older ductwork needs real mechanical cleaning, not a shop-vac hooked to a truck. Every job is backed by the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge.
This page is part of our HVAC Cleaning service hub, but everything here is written for Maryville specifically. The housing stock, the humidity, the pollen load from the Smokies foothills. It all shapes what your system needs.
Evaporator Coil Cleaning in Maryville
Evaporator Coil Cleaning in Maryville is one of the most common calls we get from Blount County homeowners whose AC runs but doesn’t cool like it used to. The evaporator coil sits inside your air handler and absorbs heat from the air. In Maryville’s humid summers, that coil stays wet for months. Dust sticks to moisture, forms a mat, and suddenly your system is working twice as hard to move half the air. A coil cleaning in Maryville typically runs $150 – $300 as part of a full HVAC cleaning package.
What We Actually Do
We access the coil, apply a foaming cleaner that breaks down the dust-and-mold film, then rinse and inspect. For heavily fouled coils, we use a coil comb to straighten bent fins and restore airflow. The whole process takes about an hour, and we photograph the coil before and after so you can see the difference.
When Maryville Homeowners Need It
If your AC runs constantly but the house won’t drop below 75, or if you see ice forming on the refrigerant line, the coil is likely starved for airflow. Homes near heavy tree cover in neighborhoods like Royal Oaks or College Park collect more pollen and cottonwood, which accelerates coil fouling. An annual coil cleaning keeps your system from working itself into an early grave.
AC Duct Cleaning in Maryville
AC Duct Cleaning in Maryville means cleaning the full network that carries conditioned air through your home: supply runs, return runs, trunklines, and register boots. Most Maryville homes still have their original ductwork, whether that’s rigid metal from the 1950s or flex runs from a 2000s addition. A full AC duct cleaning in Maryville runs $325 – $675 for a typical single-system home.
The Right Way to Clean Ducts
We use negative-pressure extraction, a method where the vacuum pulls air through the ducts while agitation tools loosen debris. Everything we knock loose goes straight into the HEPA-filtered vacuum, not back into your living room. We also camera-inspect the trunkline before and after so you see exactly what was in there. No camera, no proof. We won’t skip it.
Why One Flat Price Matters Here
Maryville’s older homes often have more registers than a comparable newer home, sometimes 14 or 16 in a 1,800-square-foot ranch. Per-vent pricing punishes these houses. We quote one flat price per system after we know the home’s layout, and that number doesn’t change when the technician counts registers. That’s the whole point.
Trusted Brands We Service in Maryville
We service and clean systems from every major manufacturer you’ll find in Blount County: Trane, Carrier, Goodman, Lennox, Rheem, and York. We stock common filters and access panels in our service vehicles, so turnaround is fast even for older units. For filtration upgrades, we carry Honeywell and Aprilaire media filters, which make a real difference in Maryville homes where spring pollen season runs long. We also use Abatement Technologies containment units on jobs where the existing dust load is severe, which keeps the work contained to the system itself.
Common HVAC Cleaning Problems We See in Maryville Homes
- Mixed ductwork in the same home. A 1960s house off East Broadway with a sunroom addition often has rigid metal trunklines feeding flexible insulated branches. Cleaning both properly requires different agitation tools, and we carry both on every truck.
- Construction dust from renovations. Maryville homeowners finish basements, add rooms, and replace floors. Drywall dust settles in the ductwork during construction and stays there for years unless physically removed.
- Humidity-driven mold on coils. Maryville’s summer humidity keeps evaporator coils damp from May through September. That moisture plus dust creates the film that reduces cooling efficiency and smells musty when the fan kicks on.
- Clogged return ducts in older homes. Many pre-1970s Maryville homes have undersized or partially blocked return paths, which makes the blower work harder and pulls more dust across the coil. Cleaning reveals the blockage, and we point it out during inspection.
We recently cleaned the supply and return ducts in a 1960s ranch off East Broadway where the original metal trunkline was feeding a newer flex branch to a sunroom addition. Using agitation tools and negative pressure, we pulled a mix of construction drywall dust and decades of lint from the trunkline, then balanced the registers and photographed the before-and-after inside the ducts so the homeowner could see exactly what came out.

FAQs About HVAC Cleaning in Maryville
Every 3 to 5 years for most homes, but homes with pets, recent renovations, or heavy tree cover may need it every 2 years. Maryville’s humidity and long pollen season push many homes toward the shorter end. If you’ve never had it done and the home is over 20 years old, it’s time. Call (737) 727-2314 for an honest assessment based on your home’s specifics.
Per system. Always. Per-vent pricing is how the bait-and-switch works: a low per-vent quote that triples once the technician counts your registers. We quote one flat price per system after assessing your home, and that number is written down before any work starts. It doesn’t change at the door.
We start with a camera inspection of your ducts to see what’s actually in there. Then we connect a negative-pressure vacuum to the system, agitate the duct walls with rotary brushes, clean the evaporator coil and blower, and finish with before-and-after photos inside your ducts. No mystery. You see what came out and what it looked like before.
Yes. Every job includes before-and-after photo documentation of the inside of your ductwork. These are photos of your actual ducts, not stock images. You’ll be able to see the trunkline, the returns, and the coil both before and after cleaning. This is part of The Relay Standard on every booking.
It can reduce the amount of dust, pollen, and pet dander recirculating through your system, especially in older Maryville homes where ductwork has accumulated decades of debris. It’s not a medical treatment, and we won’t pretend it is. But removing a thick layer of dust and pollen from the airflow path means less of it blowing through your living room every time the fan runs. For exact pricing on your home, call (737) 727-2314 and we’ll give you a written quote.
