How Pennsylvania licenses HVAC work
There is no statewide HVAC contractor license that we could find; cities or counties license HVAC work.
Who licenses: Local governments
Local rules: Pennsylvania states it has no licensure or certification requirement for most construction contractors, so HVAC licensing is left to municipalities (for example, Philadelphia requires mechanical work to be done by a licensed contractor with an active L&I license, and has a separate Warm Air Installer License page that we could not open).
Confirm the contractor's registration number on the Attorney General's Home Improvement Contractor search (https://hicsearch.attorneygeneral.gov/) (required for $5,000 or more of home improvement work a year, including central heating and air conditioning), then ask your own city or township whether it requires a local HVAC license or permit.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Pennsylvania’s own sources, so treat this as a starting point and check with the agency.

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.
