The Delaware HVAC-R Technician Guide

Delaware regulates HVACR through the Board of Plumbing, Heating, Ventilation, Air Conditioning and Refrigeration Examiners. Master HVACR and Master HVACR Restricted licenses cover HVACR work, including refrigeration and air conditioning. Apprentices, journeymen, mechanics, or other workers may work under a master HVACR licensee when the statutory exemption applies. Verify the CFC card, supervision, and local permit requirements.
