The Partnership for Air-Conditioning, Heating, Refrigeration Accreditation (PAHRA) is an independent, third-party organization that is a partnership between heating, ventilation, air-conditioning and refrigeration (HVACR) educators and the HVACR industry that awards accreditation to programs that have met and/or exceeded industry validated standards.
This programmatic accreditation program is the only one that is supported and validated by the major industry associations. As of January 2008, 44 schools in 24 states have earned PAHRA accreditation.
