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 Lewisville
HVAC cleaning in Lewisville, WA typically costs between $300 and $600 for a full system with one air handler, and most homes need it every 3 to 5 years. That’s the honest number, and we stand behind it. The Pacific Northwest’s damp marine climate means Lewisville systems collect condensation-driven biofilm inside air handlers and supply ducts, not just dust, so a proper cleaning here has to address moisture, not just surface debris. If you’re noticing musty air, weak airflow from your vents, or dust accumulating faster than it should, call us at (737) 727-2314 for a straight answer and a free estimate.
We serve all of Lewisville, from the neighborhoods near the Lewisville Riverwalk up through the residential streets off Highway 503. Our crews run Rotobrush brush systems and Nikro HEPA vacuums, and we hand you a written price before a single panel comes off your system.
Why Cardinal Air Duct Cleaning Is Lewisville’s Preferred HVAC Cleaning Company
Homeowners in Lewisville call us because we don’t do bait pricing. The quote we hand you before work starts is the invoice you pay at the end, full stop. That matters here because Lewisville’s humid climate creates a specific problem: partial cleanings that skip the air handler or ignore moisture intrusion in the supply plenum just don’t hold. A year later the musty smell is back. That’s why the 365-Day Done Right Promise exists. If the work isn’t right within 365 days, we return and correct it at no charge. No fine print, no partial coverage, every job.
Omar Haddad leads our team, and he holds every technician to the Relay Standard. That means you get a live trackable arrival window, background-checked techs in uniform who tell you their name before you open the door, before-and-after photos of your own ducts, and a digital invoice you can pay from your phone. You’ll know what we’re doing, what we found, and what we charged. Lewisville homeowners deserve that level of visibility, and we’ve built every process around it.
Our HVAC Cleaning team has worked in every corner of Lewisville, from older ranch-style homes with original metal ductwork near the river to newer construction north of town with flexible duct runs. That local familiarity means we know what a Lewisville system looks like on the inside before we open it.
AC Duct Cleaning in Lewisville
AC duct cleaning in Lewisville removes the debris, biofilm, and particulate that build up in your supply and return ductwork over the cooling season. Because Lewisville homes run air conditioning through humid spring and early summer months, condensation forms inside ducts and on the evaporator coil, which traps dust and creates a damp environment where microbial growth takes hold. The process involves brushing the duct walls with a rotary system, extracting loosened debris under negative pressure, and cleaning the air handler, blower, and coil in the same pass. For a typical single-system Lewisville home with 8 to 14 runs, expect to pay $300 to $600 depending on system size and contamination level.
Air Handler And Coil Work
The evaporator coil and air handler are where Lewisville’s moisture problem concentrates. When condensation sits on a coil through repeated cooling cycles, the coil becomes a collection point for dust, and that dust becomes a damp mat. We remove the coil from the cabinet where possible, clean it with a commercial coil cleaner, and treat the surrounding surfaces with an EPA-registered antimicrobial so the contamination doesn’t bounce back in three months.
Supply And Return Plenum Cleaning
The plenums, the large metal boxes where your ductwork meets the air handler, often hold the worst buildup in Lewisville homes. These surfaces sit out of sight, and standard per-vent pricing models tend to skip them. We clean them as part of the system-wide job, because a clean coil feeding into a dirty plenum is a wasted visit.
Furnace Cleaning in Lewisville
Furnace cleaning in Lewisville matters most in fall, when your gas or electric furnace kicks on after a long humid season sitting idle. Dust settled on the heat exchanger and blower, and any moisture left over from summer creates a baked-dust smell the first few times the system runs. The job includes cleaning the blower wheel, blower housing, heat exchanger surfaces, and the return-air path that feeds the furnace. The cost lands in the same $300 to $600 range as a full system cleaning, because we clean the entire air path, not just the furnace cabinet.
Blower And Heat Exchanger Cleaning
A dirty blower wheel in Lewisville’s damp climate often carries a coating of fine particulate that throws the wheel off balance and cuts airflow. We pull the blower assembly, clean the wheel fins by hand, and vacuum the housing before reinstalling. The heat exchanger gets brushed and vacuumed with HEPA filtration, and we inspect for cracks or corrosion while we’re in there.
Return Air Path Treatment
Your return ducts pull air from the living space back through the furnace, and in Lewisville homes with original ductwork near the river, these returns collect more than dust. Pet hair, cooking grease, and the same condensation-driven film that affects the supply side all build up here. A full return path cleaning means the air your family breathes every winter circulates through clean metal, not a coated layer.
Trusted Brands We Service in Lewisville
We work on equipment from Honeywell, Aprilaire, and Guardsman, and our trucks carry local parts stock for the most common Lewisville installations. Whether you have an Aprilaire media filter cabinet that needs a new filter, a Guardsman UV system that hasn’t been serviced, or a standard Honeywell electronic air cleaner, our techs know the equipment and carry what they need. We run Abatement Technologies containment units and Nikro HEPA extraction on every job, and Rotobrush rotary systems handle the heavy duct-wall cleaning. These are professional-grade tools, not a shop vac and a drill brush, and that’s the difference between a cleaning that lasts and one that doesn’t.
Common HVAC Cleaning Problems We See in Lewisville Homes
- Moisture-driven biofilm in air handlers. Lewisville’s humid summers create condensation inside the air handler cabinet, and that moisture feeds microbial growth on the coil and surrounding surfaces. Dry-climate cleaners often don’t treat for this because they never see it.
- Musty odors that persist after a basic vent cleaning. If a cleaning only brushes the duct walls and skips the air handler, the source stays. The smell comes back in weeks. We clean the entire air path in one visit because that’s the only way to remove the source.
- Per-vent pricing that half-cleans a system. Some Lewisville homeowners call us after a previous per-vent job left their return plenum untouched. Contamination is system-wide, not vent-by-vent, and our flat per-system price covers the full job.
- Dust accumulating within days of cleaning. This usually means the blower or coil wasn’t cleaned, or a filter wasn’t reinstalled properly. In our experience, pressure from a dirty filter or coil simply reinjects particulate into the ducts right after cleaning.
Pricing for HVAC Cleaning in Lewisville, WA
A full HVAC Cleaning in Lewisville runs $300 to $600 for a single-system home. That includes the full air path: supply ducts, return ducts, air handler, blower, evaporator coil, heat exchanger where accessible, and both plenums. Larger homes with multiple systems or long duct runs fall toward the upper end. Homes with original metal ductwork near the river sometimes need additional time due to decades of accumulated film, but we quote that before we start, not after. We charge one flat price per system, and we never price per vent. Call (737) 727-2314 for a free estimate. You’ll get a written number before any work begins, and that number won’t change at the door.

FAQs About HVAC Cleaning in Lewisville
Every 3 to 5 years for most Lewisville homes, and sooner if you have pets, allergies, or a musty smell that returns after cleaning. Our damp marine climate means microbial growth happens faster here than in drier regions, so waiting 5 years may be too long for homes near the river or with older ductwork. If you’re not sure, we can do a camera inspection and show you what’s inside your ducts before you decide on cleaning. Call (737) 727-2314 and we’ll schedule one.
Because contamination in a duct system is system-wide. Pricing per vent creates an incentive to skip the air handler, plenums, and return path, which are exactly where Lewisville’s moisture-driven contamination concentrates. A per-vent price also tends to climb once a technician is in your home, and that’s the bait-and-switch pattern we refuse to run. One flat price per system, written before we start, and it does not change.
Yes. Every job includes before-and-after photo documentation of your own ducts, coils, and plenums. You see what we found and what we cleaned. It’s part of The Relay Standard, and it means you never have to take our word for the work. Call (737) 727-2314 to book, and the photos are part of the job by default.
Yes, when the odor comes from microbial growth inside the air handler or ducts, which is the most common cause in Lewisville’s humid climate. We were called to a home near the Lewisville Riverwalk after the homeowner noticed a musty odor and reduced airflow. Our tech performed a camera inspection and found heavy biofilm on the evaporator coil and supply ducts, cleaned the full system with negative pressure and HEPA filtration, and applied an EPA-registered antimicrobial treatment. The homeowner reported immediate improvement in air quality and airflow. If your musty smell is coming from a different source, a camera inspection will tell us that too.
We don’t offer same-day service. Proper equipment setup, negative pressure, and HEPA filtration take time, and rushing that process is how corners get cut. We schedule your cleaning for the next available slot, give you a live trackable arrival window, and never promise a speed we won’t deliver. Call (737) 727-2314 and a live person will help you book a time that works.
