Call (844) 685-6342 for a free estimate.
We’ve been serving Louisville homeowners since 2012, and we know the difference between a ranch in Pleasure Ridge Park and a converted Victorian in Old Louisville. That matters because your ductwork is shaped by when your home was built, what it was built from, and what the Ohio River Valley climate has done to it since. We don’t guess. We camera-inspect before we touch a tool, show you what we find, and give you one honest price before work starts.
Our uniformed, background-checked technicians arrive with Rotobrush flexible extension systems sized for irregular duct cross-sections, plus the truck-mounted power units that make long rural service drives practical. Most jobs finish in one trip. We stand behind every one with our 90-Day Done Right Promise in writing.
Why Bellows Air Duct & Vent Co. Is Louisville’s Preferred HVAC Cleaning Company
Ray Castillo has led Bellows Air Duct & Vent Co. since its founding in 1984, building a reputation across Louisville on one principle: no surprises on the bill, no arguing if something needs fixing. Our 90-Day Done Right Promise means if the work isn’t right, we return at no charge with no paperwork required. That’s not marketing language. It’s stamped on every invoice.
Louisville homeowners call us because they’ve learned the hard way that bait-coupon pricing leads to upsells at the door. We disclose every cost before lifting a single tool. The number on the phone is the number on the invoice. Our camera inspection gives you a visual record of before and after, not just a claim.
We know Louisville’s housing stock intimately. The 40201-40210 ZIP codes covering Old Louisville and the urban core contain some of the most challenging duct configurations in the Midwest: early-1900s homes with central forced-air retrofitted through narrow plaster-and-lathe wall cavities, original gravity-furnace trunk lines converted to low-velocity settling chambers, and decades of accumulated debris that standard equipment simply cannot reach. We bring the tools and the patience for that work.
Calls are answered by a live person, not voicemail, not an app, 24 hours a day. Our technicians are background-checked and uniformed on every job. We’ll be there when we say.
Our HVAC Cleaning Services in Louisville
Evaporator Coil Cleaning
Louisville’s persistent humidity bowl, produced by its Ohio River Valley location, creates condensation on evaporator coils year-round. That moisture breeds mold and mildew faster here than in drier inland cities at similar latitudes. We remove the biological growth that restricts airflow and forces your compressor to work harder, then apply antimicrobial coil treatment to slow regrowth. A typical evaporator coil cleaning in Louisville runs $180-$340.
Coil Treatment
Cleaning without treatment is half the job in this climate. Louisville’s high relative humidity means coils that are merely cleaned will re-contaminate quickly if the moisture source isn’t addressed. Our coil treatment uses professional-grade solutions from Abatement Technologies to create a protective barrier on coil fins, extending cleanliness through the heavy cooling season. Coil treatment as an add-on service typically runs $75-$125 in the Louisville market.
Air Handler Cleaning
The air handler is where your Louisville home’s air is actually moved, heated, and cooled. In acreage properties with detached workshops or oversized garages, heavy-duty equipment often pulls dust and debris into the main house duct system through shared handlers. We disassemble and clean blower assemblies, housings, and return plenums, checking for the pollen accumulation that Louisville’s valley geography makes unavoidable. Air handler cleaning in Louisville generally runs $220-$380.
Blower Cleaning
A dirty blower wheel cuts airflow by 30% or more, forcing longer run times during Louisville’s muggy summers and cold Ohio Valley winters. We remove the blower assembly for thorough cleaning off-site when needed, restoring rated CFM without damaging the balanced wheel. Most blower cleanings are completed same-day in Louisville.
Condenser Cleaning
Outdoor condensers in Louisville collect cottonwood seed, grass clippings, and the fine particulate that settles in the Ohio River basin. We fin-comb and chemically clean condenser coils to restore heat rejection capacity, particularly critical before the long cooling season that runs May through September in this market.
Heat Exchanger Cleaning
Older Louisville homes with original or replacement furnaces need heat exchanger inspection and cleaning to ensure safe, efficient combustion. We camera-inspect for cracks and deposits that could affect performance or safety, cleaning where accessible and documenting conditions for your records.

Trusted Brands We Service in Louisville
We clean and service equipment from Aprilaire, Abatement Technologies, and Rotobrush, the same brands serious HVAC contractors specify for their own jobs. Our Louisville warehouse stocks common replacement parts and maintenance consumables, so we’re not waiting on shipping while your system sits down. For specialized components in historic homes or custom installations, we source through local distributors on Bardstown Road and in the East End with same-day or next-morning availability. That parts access, combined with our truck-mounted power units, is why we finish most Louisville jobs in a single visit.
Common HVAC Cleaning Problems We See in Louisville Homes
- Mold in supply runs from humidity condensation. Louisville’s Ohio River Valley location produces a persistent humidity bowl with high relative humidity year-round. Condensation forms inside duct systems and accelerates mold growth, a failure mode more severe here than in drier inland cities. Cleaning fails if technicians skip antimicrobial coil treatment and don’t address the moisture source.
- Irregular duct accumulation in Old Louisville Victorians. The 40201-40210 ZIP codes cover homes with central forced-air retrofitted through narrow plaster-and-lathe wall cavities. Original gravity-furnace trunk lines running beneath first-floor joists were never designed for forced-air velocity. They act as low-velocity settling chambers where pollen, insulation fibers, and combustion byproducts accumulate in thick layers.
- Pollen loading from the Ohio River Valley basin. Louisville sits in a geographic trap for tree pollen, grass pollen, and ragweed. The Asthma and Allergy Foundation of America has repeatedly ranked Louisville among the worst U.S. cities for allergy sufferers. Duct systems here reach problematic particulate levels faster than in peer Midwest cities.
- Heavy-duty contamination on acreage properties. Detached workshops and oversized garages with heavy-duty equipment pull dust and debris into duct systems shared with the main house. Standard portable cleaning equipment cannot handle the volume or the long service drives. Our truck-mounted units and oversized capacity are built for this.

FAQs - HVAC Cleaning in Louisville
Old Louisville’s converted Victorian homes contain original gravity-furnace trunk lines that act as low-velocity settling chambers for pollen, insulation fibers, and combustion byproducts, and their narrow plaster-and-lathe wall cavities create irregular duct cross-sections that standard equipment cannot reach. In Old Louisville, we tackled a Victorian home where original gravity-furnace trunk lines under the first floor acted as settling chambers for decades of pollen and debris. Our Rotobrush equipment, fitted with flexible extension tooling, extracted thick layers that standard rotary brushes couldn’t reach, restoring airflow and reducing allergens for the homeowner. Without this specialized approach, cleaning leaves behind the very contaminants that aggravate Louisville’s already severe allergy conditions. Call (844) 685-6342 to schedule a camera inspection of your historic home’s ductwork.
Louisville’s Ohio River Valley location creates a persistent humidity bowl that promotes condensation inside duct systems and accelerates mold and mildew growth more severely than in drier inland cities at similar latitudes. The city’s full dual-season HVAC demand, heavy air conditioning through long, muggy summers and active heating through cold Ohio Valley winters, keeps systems running nearly continuously and compresses the window before ducts reach problematic particulate levels. This combination of moisture and constant use means Louisville homeowners face faster contamination cycles than residents of cities with milder summers or drier climates. We address this with antimicrobial coil treatment and moisture-source identification on every job. Call (844) 685-6342 for a system evaluation.
Yes, our truck-mounted equipment is specifically configured for long service drives and detached structures on acreage properties throughout Jefferson County and surrounding areas. Standard portable cleaning units cannot handle the volume of debris or the logistics of rural properties; we bring oversized capacity and the power to clean systems that serve both main houses and outbuildings. Our technicians are background-checked and uniformed, and we answer calls live 24 hours a day, so you’re not waiting on voicemail when a workshop system goes down. Call (844) 685-6342 to discuss your property’s specific access and equipment needs.
Yes, HVAC cleaning measurably reduces indoor allergen loads, which is especially significant because Louisville sits in the Ohio River Valley basin, a geographic trap for pollen and ragweed that has earned it repeated rankings among the worst U.S. cities for allergy sufferers by the Asthma and Allergy Foundation of America. Louisville homeowners have a medically documented, stronger reason to keep ductwork clean than residents of most peer Midwest cities. We target the pollen accumulation, mold spores, and dust mite habitats that thrive in Louisville’s humid duct conditions, with camera-verified removal you can see. Our coil treatment and antimicrobial applications extend protection through peak pollen seasons. Call (844) 685-6342 to schedule before the next high-pollen period.
We use professional-grade equipment from Rotobrush, Abatement Technologies, and Aprilaire, the same brands serious HVAC contractors specify for their own installations. Our Rotobrush systems include flexible extension tooling specifically sized for the irregular duct cross-sections common in pre-1930 Louisville construction, and our Abatement Technologies antimicrobial treatments address the moisture-driven mold growth that Louisville’s humidity bowl produces. We do not use rental-grade or consumer equipment on professional jobs. Every clean is camera-documented before and after. Call (844) 685-6342 to see the difference proper equipment makes.
