ASTI

What ASTI does

Air Source Technology, Inc. (ASTI) is a privately held environmental, health and safety (EHS) consulting firm founded in 1994 and headquartered in Lexington, Kentucky, with a secondary office in the Greater Louisville area. The company delivers on-site diagnostic, compliance, and training services to Industrial, Commercial, Residential, Healthcare, and Institutional clients across Kentucky and the broader Southeastern United States, and self-identifies as nationally recognized for Indoor Air Quality investigations.

The firm's core offering is organized into six service lines: Indoor Air Quality and Mold Services (water intrusion, ventilation, GC/MS broad chemical screens, bioaerosol testing, radon, ASHRAE Method 113, IR thermography); Industrial Hygiene and OSHA Compliance (exposure assessments, welding fume monitoring, asbestos risk, local exhaust ventilation, noise dosimetry, lead surveys); Safety Training and Consulting (OSHA audits, HAZCOM, lockout/tagout, confined space, fit testing, forklift and electrical safety); Building Science and LEED (HVAC efficiency, moisture management, envelope studies, LEED IEQ commissioning); Hospital and Healthcare Facilities (USP 797/800 cleanroom certification, CETA testing, ICRA construction monitoring, medical gas verification, Legionella sampling); and Asbestos and Lead (AHERA inspections, management plans, KY lead risk assessments). Delivery is field-based using advanced instrumentation — real-time ambient air analyzers, GC/MS, certified infrared cameras, and biosafety cabinet certification tools — performed by Board-certified Industrial Hygienists, Council-certified Indoor Environmental Consultants, and AHERA-certified inspectors.

ASTI operates a direct-services, quote-based consulting model with no publicly disclosed pricing, no digital self-serve channels, and no software or SaaS product layer. Revenue mechanics are driven by per-engagement professional services fees across its six service lines, with notable customer stickiness in the Kentucky K-12 AHERA asbestos segment (90+ school districts under ongoing records management). Marketing and business development are conducted through professional association memberships (AIHA, APIC, CETA, IEST, KSHE) and direct client relationships rather than a structured GTM motion.
