About HVAC in Port St. Lucie
Port St. Lucie sits on Florida's Treasure Coast, where summer highs average in the low 90s°F and winter highs stay in the 70s, so air conditioning runs most of the year and heat is needed only on a few cool nights. 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). The city was hit directly by three hurricanes in 2004 and 2005, and storm damage to outdoor units is a common reason for repairs here. Ranked by license record and years licensed, never by payment.
