Why Ohio runs above the US average
Radon mitigation pricing in Ohio reflects three regional factors: licensed HVAC / specialty trade wages (BLS), EPA Zone density (Zone-1 states have mature mitigator markets and competitive pricing), and state-specific permitting / disclosure requirements. The 1.00× factor is calibrated from 2025 AARST + HomeAdvisor regional rate data.
