About HVAC in Orlando

Orlando has a humid subtropical climate: July and August average daily highs of about 92°F, and the hot, rainy season runs from May until late October, so air conditioning carries most of the year, while January nights average about 50°F and frost comes on only one or two nights a year. Florida licenses HVAC contractors through the Department of Business and Professional Regulation's Construction Industry Licensing Board, either statewide as Certified Air Conditioning Contractors (CAC, Class A or B) or as locally Registered contractors (RA). Ranked by license record and years licensed, never by payment. Checked 28 October 2026.
