Checking an HVAC company in the Allentown area
HVAC licenses in Pennsylvania
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.
Sources: pa.gov, attorneygeneral.gov, attorneygeneral.gov, phila.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Getting through a Allentown winter
Heating season is the long one in Allentown, so the furnace, boiler or heat pump does most of the work. Start with these before the first cold snap – and keep carbon monoxide alarms working.
