Why Florida runs below the US average

Radon mitigation pricing in Florida 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 0.94× factor is calibrated from 2025 AARST + HomeAdvisor regional rate data.

Local note · Florida: Zone 2-3 mostly low-risk. Slab-on-grade dominates — sub-slab systems are simpler/cheaper here than basement states. Florida Radon Program licenses mitigators separately from NRPP/NRSB.
