CAC License

Certified AC Contractor

Heating, ventilation, and air conditioning — essential in Florida

A Florida Certified Air Conditioning Contractor (CAC) is licensed to install, maintain, service, and replace all HVAC systems — central air, ductless mini-splits, heat pumps, ventilation systems, and indoor air quality equipment. In Florida's year-round heat and humidity, your HVAC system is your home's most critical mechanical system, and proper licensed installation directly impacts your energy bills, comfort, and indoor air quality.

What a CAC Can Do

Under Florida Statute §489.105(3)(f), a Certified Air Conditioning Contractor may install and service:

  • Central split air conditioning and heat pump systems
  • Ductless and multi-zone mini-split systems
  • Package units (rooftop and ground-mounted)
  • Ductwork installation, repair, sealing, and replacement
  • Ventilation systems including exhaust fans and energy recovery ventilators
  • Indoor air quality systems: UV lights, air purifiers, humidifiers/dehumidifiers
  • Refrigerant charging and handling (EPA 608 certification required)

Why Homeowners Should Hire a Licensed CAC

HVAC replacement requires a building permit in Florida, and permits require licensed CAC contractors. Beyond legality, proper HVAC installation involves refrigerant handling (a federally regulated substance), precise load calculations to correctly size the system, duct sealing to prevent efficiency losses, and compliance with Florida's SEER2 minimum efficiency standards. A correctly sized and installed system will outperform an improperly installed high-end system every time — and in Florida's climate, the difference in comfort and energy cost is significant.

What to Look for When Hiring

  • Active "CAC" license verified on FloridaContractorCheck
  • Willingness to perform a Manual J load calculation to right-size your system
  • Knowledge of Florida's SEER2 requirements and available utility rebates
  • Experience with coastal/salt-air installations if applicable
  • Manufacturer certification for the equipment brand they're installing
  • Clear explanation of warranty: manufacturer parts + labor warranty
