Louisville Air Duct Cleaning: 21 Verified Companies with Pricing & Credentials

📋 21 verified companies ✅ 5 NADCA-certified 🕐 Updated March 2026

Five NADCA-certified air duct cleaning companies serve the Louisville bi-state metro as of March 2026 — the smallest certified roster of any major Southern metro we have reviewed, in a city where the need is arguably highest. Louisville sits at the bottom of the Ohio River Valley in a humid subtropical climate with average annual humidity of 68–70% and over 200 days per year where relative humidity exceeds 60%, the threshold above which mold actively grows inside ductwork. Locals call the resulting chronic respiratory issues the "Ohio Valley Crud." This directory covers all 21 verified companies across Tier 1 (NADCA-certified), Tier 2 (legitimate non-certified), and flagged/suspect listings — with transparent verification data, KY licensing notes, and red flags clearly marked.

Louisville's market has two distinctive features that set it apart. First, the housing stock spans extremes: Old Louisville's Victorian preservation district — the largest in the United States — contains 1870s–1900s homes with gravity furnace conversions, potential asbestos insulation, and non-standard ductwork that can cost $600–$1,200+ to clean properly. The 1950s–60s suburban ring (St. Matthews, Okolona, Shively, Hikes Point) has decades of accumulated debris in original sheet metal systems. Second, the bi-state geography means Southern Indiana residents (New Albany, Jeffersonville, Clarksville) are served by only one NADCA-certified firm based across the river. Harrison County (Corydon, IN) is especially underserved. Every company listed here was independently verified through NADCA membership records, BBB profiles, and cross-referenced consumer review platforms.

Kentucky requires HVAC contractors to be licensed through the Department of Housing, Buildings, and Construction (DHBC), though pure duct cleaning (not installation or repair) occupies a regulatory gray area. Only one company in this directory — Jarboe's Heating, Cooling & Plumbing — publicly posts its KY HVAC license number (HM01276) on its website, a transparency practice other companies should follow. Our verification identified 11 flagged listings operating in Louisville search results, including coordinated lead-generation networks, a company using a Michigan phone number, and another with documented Google reviews describing it as a scam.

⚠️ FLAGGED — VERIFY BEFORE HIRING

"Duct Cleaning Louisville KY" (ductcleaninglouisvilleky.com)

Out-of-State Phone (810 Flint MI) Lead Gen Network
⚠️ Phone number has an 810 area code (Flint, Michigan) — not a Louisville local number. Contact email is a personal Gmail (j.giannattasio10@gmail.com). Website links to ductcleanerscharlotte.com, confirming this is part of a multi-city lead-generation network. Address (411 Hancock Green Pl, Louisville 40202) is likely virtual. No NADCA membership, no KY HVAC license, no BBB listing, no insurance information. SEO-stuffed template content. Very high confidence this is a spam/lead-gen operation.

"AirClear Solutions" (airclearsolutions.com)

No Local Phone Number New Domain (Aug 2025)
⚠️ Toll-free number only — no local Louisville phone number. No physical address listed. All social media links on the website are nonfunctional "#" placeholders. Domain created approximately August 2025 (very new). Generic WordPress template. No NADCA membership, no DHBC license, no BBB listing. Very high confidence this is a spam listing.

"Kentucky HVAC Pros" (la-grange-ky.catrudeauplumbingandhvac.com)

Non-US Template Origin Subdomain of Different Company
⚠️ This is a subdomain of a completely different company's website. Content contains British spellings ("sanitisation," "mould," "optimise") — revealing non-US template origin. No physical address. Auto-generated content targeting La Grange, KY. No NADCA, no DHBC license, no BBB. Very high confidence this is a foreign-origin template spam site.

"Air Duct Cleaning & Repairs" network (airductcleaningnewalbany.com / airductcleaningjeffersonville.com / clarksvilleairductcleaning.com)

Coordinated Lead Gen Network False NADCA Claims
⚠️ Coordinated lead-generation network operating multiple city-name-only domains across Southern Indiana and Louisville. All sites use identical templates. All claim "Founded 2015, A+ BBB, 5-Star Google" — unverifiable on any of these properties. No physical addresses. Copy-pasted Wikipedia text on some pages. Claims "NADCA-aligned protocols" without actual NADCA membership — misleading language designed to deceive consumers searching for certified companies. Avoid all sites in this network.

"American Air Duct Cleaning Louisville" (americanlouisville.com)

Out-of-State Phone (720 Denver CO) Documented Scam Reports
⚠️ Phone number has a 720 area code (Denver, Colorado) — not a Louisville local number. Google review states: "Scam business. They came out once but failed to perform all cleaning required. When trying to call to get them to come back out they blocked my number. Looking at the other reviews it seems like a lot are bots." Very high confidence this is a scam operation. Do not hire.

"New Albany Air Duct Cleaning" (newalbanyairductcleaning.us)

Out-of-State Phone (380 Columbus OH) Self-Described Referral Aggregator
⚠️ Phone number has a 380 area code (Columbus, Ohio) — not a Southern Indiana local number. The website itself states "Our network is an array of trusted local service pros" — explicit referral/aggregator language. No physical address. High confidence this is a lead-generation site routing calls to unvetted contractors.

Groupon Operators: Mr Airduct / Mathew HVAC Cleaning / FreshBreeze Services

Groupon Only Up to 90% Off Claims
⚠️ Three Groupon-only operators advertising Louisville HVAC/duct cleaning: "Mr Airduct" (up to 90% off HVAC cleaning), "Mathew HVAC Cleaning" (up to 82% off), and "FreshBreeze Services" (up to 82% off). None have verifiable physical addresses, no NADCA membership, no DHBC licenses, no independent BBB listings. Discounts at this level (80–90% off) are a definitive indicator of bait-and-switch tactics. Moderate–high confidence these are problematic operators.

Additional Low-Moderate Concern Listings

Verify Before Hiring
⚠️ Two additional listings warrant consumer caution: "Louisville Kwik Dry Total Cleaning" — $199 base price is below industry norms but above scam-range; includes only 10 vents with a $30/vent upsell model. Appears to be a legitimate cleaning company with multiple services, but pricing model warrants careful scope-of-work confirmation before booking. "Dryer Vent Cleaning 5 Star" (dryerventcleaning5star.com, Jeffersonville page) — content reads like affiliate/product marketing; sells cleaning kits and equipment rather than performing local service. Not a genuine local service company.

Frequently Asked Questions

Does an air duct cleaning company need a license in Kentucky?
Kentucky requires HVAC contractors to be licensed through the Department of Housing, Buildings, and Construction (DHBC), which has mandated licensing since July 1995. Three tiers exist: apprentice (works under supervision), journeyman HVAC mechanic (2 years under a master, exam required), and master HVAC contractor (journeyman for 2+ years, master exam, $500,000 general liability insurance required). A limited "ductwork journeyman" license covers ductwork-only projects. However, air duct cleaning exists in a regulatory gray area — pure cleaning (not installation or repair) is not explicitly addressed in KRS 198B.650–198B.689. Many duct cleaning companies operate as general cleaning businesses without HVAC licenses. When work extends to HVAC components (blower motors, coils, air handlers), licensing is clearly required. Consumers should look for NADCA certification as the primary duct-cleaning-specific credential and verify KY HVAC license numbers at the DHBC portal (dhbc.ky.gov) or by calling (502) 573-2002. Jarboe's Heating, Cooling & Plumbing (KY license HM01276) is one of the very few companies that publicly posts its license number.
What makes duct cleaning different in Old Louisville Victorian homes?
Old Louisville is the largest Victorian preservation district in the United States, spanning 48 city blocks with nearly 1,400 homes built between the 1870s and early 1900s. These homes were designed for gravity furnaces ("octopus furnaces") or boiler/radiator systems — not modern forced-air HVAC. When central air was retrofitted decades later, ductwork was often squeezed into cramped spaces with original gravity-era ducts narrowed, extended, or improvised to work with modern systems. Challenges include: oversized original trunk lines that collect debris differently than standard ducts, non-standard routing through walls and between floors, limited access points requiring specialized equipment, and — in pre-1960 conversions — potential asbestos wrapping on original ductwork that must be professionally tested and abated before any cleaning. Multi-story configurations with high ceilings mean longer duct runs and more square footage per home. Expect cleaning costs of $600–$1,200+ for these properties, and seek contractors with documented experience in historic homes. The Highlands, Cherokee Triangle, and Crescent Hill neighborhoods share similar challenges.
How do I spot the $49/$79 bait-and-switch duct cleaning scam in Louisville?
Warning signs specific to Louisville include: unsolicited phone calls, door-knocking, or Facebook/Nextdoor posts offering whole-house cleaning for $49–$99 (legitimate whole-house cleaning for a typical Louisville home runs $300–$600); phone numbers with area codes outside 502 (Louisville), 812 (Southern Indiana), or 270 (surrounding Kentucky) — flagged examples include a company using an 810/Flint, Michigan number and another with a 720/Denver, Colorado number; Groupon offers advertising 80–90% discounts on HVAC cleaning; no verifiable physical address in the Louisville metro area; and websites with city-name-only domains (e.g., "ductcleaninglouisvilleky.com") that link to companies in other cities. NADCA and multiple Louisville-area companies (One Choice Mechanical, Stanley Steemer) explicitly warn consumers about these operators. The typical scam pattern: arrive, clean only vent covers with a shop vacuum, then pressure the homeowner into thousands of dollars of "mold remediation" or additional services. Affordable Air Duct Cleaning LLC even posts a warning on their website that scammers impersonate their business on social media.
Why does Louisville's climate make duct mold a bigger concern than in most cities?
Louisville sits in the Ohio River Valley in a humid subtropical climate zone (Köppen Cfa) with average annual humidity of 68–70% and over 200 days per year where relative humidity exceeds 60% — the threshold above which mold actively grows. The Ohio River itself creates a microclimate effect, trapping moisture in the valley. Louisville averages 48+ inches of annual rainfall distributed across all months. The region's infamous "Ohio Valley Crud" — chronic sinus and respiratory issues among residents — is driven partly by mold spores circulating through dirty ductwork. Basements and crawl spaces, standard in Louisville's housing stock, create additional moisture intrusion pathways into duct systems. Recent years have amplified this risk: 2025 alone brought January snowmelt, February flooding with 2–6 inches of rain, and April historic flooding — all driving moisture into homes and HVAC systems. SERVPRO of East Louisville reports handling approximately 1,000 water mitigation jobs annually. After any water intrusion event, duct inspection and cleaning should be an immediate priority.
I live in Southern Indiana — should I hire a Kentucky or Indiana company for duct cleaning?
Both can work, but consider several factors. Only one NADCA-certified duct cleaning company is physically based in Southern Indiana: Preferred Air Duct Cleaning in Clarksville (812-225-8560). Many reputable Louisville-based companies — Coit, Stanley Steemer, Jarboe's, Boston Carpet & Air Duct Cleaning, A-1 Kwik Dry, and at least a dozen others — explicitly serve Floyd, Clark, and Harrison counties. If you hire a KY-licensed HVAC company for work beyond simple cleaning (e.g., duct repair or sealing), confirm they hold Indiana credentials. Jarboe's, for example, holds both KY license HM01276 and IN license H0010016. Indiana does not have statewide HVAC licensing; requirements vary by municipality, which means less regulatory oversight but also lower barriers for unqualified operators. Harrison County (Corydon) residents should expect longer travel times and potentially higher trip charges, as most companies are based in Clark County or Louisville. Pricing in Southern Indiana typically runs approximately 5–10% below KY-side rates for comparable services.
How does Louisville's long cooling season affect duct cleaning frequency?
Louisville's cooling season runs roughly late April through October — approximately 6 months — with summer highs of 85–90°F+ and high humidity. This extended runtime means AC systems push air through ducts for substantially more hours annually than in northern cities, accelerating the accumulation of dust, allergens, and moisture-related contamination. NADCA recommends cleaning every 3–5 years for typical homes, but Louisville-area providers often recommend every 2–3 years given the climate. Homes with pets, smokers, allergy sufferers, or recent renovations may need annual inspections. The best times to schedule are early spring (March–April, before cooling season) or early fall (September–October), when demand is lower and technicians can assess pre-season system condition. Booking during these shoulder seasons may yield faster scheduling and potential off-peak discounts.
What should homeowners in 1950s–60s St. Matthews, Okolona, or Shively homes expect from first-time duct cleaning?
Louisville's mid-century suburban ring — St. Matthews, Okolona, Shively, Hikes Point, Fern Creek, and Jeffersontown — features homes built primarily in the 1950s and 1960s, many with original sheet metal ductwork that has never been professionally cleaned. These homes typically have basements or crawl spaces where humidity-exposed ductwork develops leaks, rust, and mold over decades. Expect the first cleaning to be more intensive (and potentially more expensive) than maintenance cleanings. Technicians may find 6+ decades of accumulated dust, pet dander from previous owners, construction debris from renovations, and potentially deteriorated duct insulation. Original sheet metal joints may have loosened, and era-appropriate duct tape repairs will likely have failed. A thorough first cleaning for a typical 1,200–1,800 sq ft mid-century home should run $350–$500. If significant deterioration is found, the contractor may recommend duct sealing or partial replacement — get a second opinion if repair quotes exceed $1,000.
Should I combine air duct cleaning with dryer vent cleaning in Louisville?
Yes — and most Louisville-area companies offer bundled pricing. Dryer vent cleaning is a fire safety issue (lint buildup is a leading cause of residential fires), and combining it with duct cleaning saves on the trip charge and setup time. Typical Louisville-area pricing for standalone dryer vent cleaning runs $79–$150 depending on configuration (side-wall venting is cheaper than roof-exit venting). Affordable Air Duct Cleaning LLC offers 50% off dryer vent cleaning with a duct cleaning purchase. Several Louisville companies specialize exclusively in dryer vents — Dryer Vent Squad of Louisville (502-712-0333), Dryer Vent Wizard of Kentuckiana, and Dryer Vent Superheroes (502-237-0613) — and can provide focused expertise if the dryer vent is the primary concern. When getting duct cleaning quotes, always ask if dryer vent service is included or available as an add-on.
Methodology & Data Sources

This directory is built from independent verification, not advertising revenue or business submissions. We do not accept payment from listed companies and do not rank companies based on sponsorship.

Data sources:

  • NADCA Find a Professional directory (nadca.com/find-a-professional)
  • Kentucky DHBC License Verification (dhbc.ky.gov)
  • BBB Serving Greater Kentucky
  • Google Business Profiles
  • Yelp

Exclusion criteria: A business is excluded from the verified listings and marked as flagged if it uses a virtual office or PO Box as its only address with no verifiable operational presence; shows patterns consistent with lead-generation fronts (generic city-keyword domains, template websites, no owner identification); uses phone numbers with area codes outside the Louisville metro (502), Southern Indiana (812), or surrounding Kentucky (270); or advertises pricing below $199 for whole-house cleaning, which we consider a definitive bait-and-switch indicator in this market.

Louisville-specific verification note: Kentucky's DHBC HVAC licensing exists but does not explicitly cover pure duct cleaning (not installation or repair). We verify HVAC license numbers only when companies advertise repair, replacement, or equipment work. For NADCA certification, we verify directly through the NADCA public directory — not through company self-reporting. The most common fraud in this market is companies claiming NADCA "standards" or "protocols" (not actual membership) and companies using out-of-state phone numbers to appear local.

Update frequency: This directory is reviewed quarterly. NADCA membership status is re-verified at each review through the primary NADCA directory. The most recent verification was completed in March 2026.

Report an error or suggest a business: If you believe a listing contains incorrect information, or if you know of a legitimate air duct cleaning company in Louisville that should be considered for inclusion, please contact us. We will verify the submission against our standard criteria before adding it.
