Best Air Duct Sanitizing & Mold Services in Lafayette, IN
What to look for in Air Duct Sanitizing in Lafayette
Sanitizing is the most over-sold duct service — the EPA is explicit that antimicrobial treatment belongs after a documented mold finding and a mechanical clean, not as a default upsell. We weight providers who hold IICRC mold credentials and sequence cleaning before treatment over those who push fogging on every job.
- Sanitizing / IAQ specialization. Provider lists antimicrobial sanitizing, deodorizing, or indoor-air-quality treatment as a distinct service with method detail (EPA-registered product, cleaning-first sequence).
- Mold remediation credential. IICRC or NADCA VSMR certification signals a real mold scope — a lab-test mindset rather than an on-site "I see mold" upsell.
- Google rating. Sanitizing claims are easy to make and hard to verify, so a strong rating floor with outcome-specific reviews is the trust threshold.
Verify before you book
- Whether "sanitization" uses EPA-registered products — ask for the product name and registration number.
- Active IICRC / VSMR certification (registry lookup is the verification step) — we accept self-claimed.
- Whether a mold claim was confirmed by a lab test — the EPA notes a visual check can't confirm in-duct mold.
