Austin Air Duct Cleaning: 17 Verified Companies with Pricing & Credentials

• NADCA Certified
  The National Air Duct Cleaners Association is the only trade body specific to this industry. NADCA membership requires at least one ASCS (Air Systems Cleaning Specialist) certified technician on staff and adherence to the ACR standard for assessment, cleaning, and restoration. Only 6 Austin-area companies currently hold active NADCA certification — verified directly through NADCA's public directory, not through company self-reporting. At least 5 other companies falsely claim it.
• TDLR License (for repair/mold work)
  Texas does not require a license for basic duct cleaning, but any company cutting into ductwork, performing modifications, or doing mold/biomedical remediation must hold a TDLR Air Conditioning and Refrigeration Contractor license (TACL number). Verify any claimed license at tdlr.texas.gov. IAQ Experts is the only Austin duct cleaning company that explicitly displays a TDLR number (TACLB55384E) on its NADCA listing — a meaningful signal. Abacus has multiple TDLR licenses on record.
• Local Phone Number
  Austin's legitimate companies use 512 or 737 area codes. Toll-free numbers (800, 844, 855, 877, 888) are a yellow flag for multi-city template operations that route calls to unvetted subcontractors. Several flagged operations in this directory use toll-free numbers as their only contact method. The presence of a local 512/737 number does not guarantee legitimacy, but its absence alongside other red flags is significant.
• Transparent Pricing
  The Austin baseline for whole-house residential duct cleaning is $350–$700, with the Angi metro average at $418. Companies advertising $49–$99 whole-house specials are using bait-and-switch tactics — the documented pattern involves arriving, performing superficial work, then pressuring homeowners into $800–$2,000+ upsells for "discovered" mold, damaged insulation, or urgent hazards. We mark pricing as transparent when a company publishes actual rate ranges or specific quotes during initial consultation.
• Years in Business
  Longevity matters more in duct cleaning than most home services because barrier to entry is low and operators frequently rebrand after accumulating complaints. Austin's longest-operating companies — K&M Steam Cleaning (1996, 30 years), The Steam Team (1983, 43 years), Roznovak's (1979, 47 years) — have demonstrated sustained quality under consistent identity. Short operating history combined with other yellow flags warrants extra verification.

Exclusion criteria: A business is excluded from this directory if it uses a virtual office, PO Box, or PMB 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); falsely claims NADCA certification not confirmed in the NADCA directory; advertises pricing below $200 for whole-house cleaning, which we consider a definitive bait-and-switch indicator in the Austin market; or has an out-of-market phone area code (non-512, non-737) without a confirmed local operational base.

Texas-specific verification note: Texas does not require a state license for basic duct cleaning. We do not penalize companies for lacking a TDLR license when they perform cleaning only (no cutting or repair). For companies advertising repair, modification, mold remediation, or biomedical work, we verify TDLR TACL license status. The TDLR license lookup at tdlr.texas.gov is the authoritative source — not company websites or marketing materials.

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.
