Local rules: The MSBOC pages we read say nothing about city or county HVAC licensing, so we could not confirm any local rules.
Check a license: search.msboc.us
Search the company on the MSBOC consolidated search and confirm it holds an active HVAC or Residential HVAC classification.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.

Before you hire
Ask for the license number and check it on the official lookup where one exists. Ask for proof of insurance and a written, itemized estimate, and ask who pulls the permit if the job needs one – a new furnace, heat pump or air conditioner usually does.
