The short version
HVAC licensing is the wildest patchwork of the three trades: full state ladders (Maryland, Texas), contractor-only states (Florida, Ohio), and no-license states (Illinois, Colorado) — but EPA 608 certification is federal law everywhere refrigerants are involved.

FAQ
Which states have the toughest HVAC technician licensing?
Measured by published hours, the strict ladder states cluster around 8,000 supervised hours for journeyman level (Texas, Washington, Michigan, Colorado for electricians). Contractor-only states look "easier" on paper but require 3–5 documented years to contract legally.
Which states don't license HVAC technicians at all?
It varies by trade — see the "local rules" rows in the table. Pennsylvania licenses none of the three trades statewide; Illinois licenses plumbers but not electricians; New York leaves all of it to cities.
