About HVAC in Clearwater
Clearwater has a humid subtropical climate: average highs reach about 90°F in July and August and summer brings daily thundershowers, so air conditioning runs for most of the year, while January nights average about 53°F. Florida HVAC contractors are licensed by the Department of Business and Professional Regulation’s Construction Industry Licensing Board as Certified Air Conditioning Contractors (CAC, Class A or B).
