KY HVAC case studies

The Kentucky HVAC Contractor Licensing Examination is a trade licensure exam for people who intend to contract for heating, ventilation and air conditioning work in the Commonwealth. It is aimed at experienced technicians moving into business ownership as well as established contractors adding a credential, and it tests the full scope of the trade rather than a single product line: refrigeration principles and system components, heating equipment and combustion safety, air distribution, ventilation and indoor air quality, electrical systems, motors and controls, load calculation, sizing and system design, and the codes, permits and business practices that govern contracting. The statewide regulatory backdrop is the Kentucky Department of Housing, Buildings and Construction, which states that it "enforces statewide standards for building construction" and licenses and certifies trades including plumbers, electricians, boiler contractors, sprinkler and fire alarm contractors and building inspectors. Candidates should confirm current application, examination and renewal requirements directly with the department, because the agency's published news items - including a July 15, 2026 item titled "HVAC Equipment" and 2026 NEC updates - do not state any resulting change to HVAC examination content, item counts or pass standards. The KY HVAC case studies are 5 cases and about 2,147 words.
