In Florida, HVAC contractors must hold a license issued by the Construction Industry Licensing Board under the Department of Business and Professional Regulation (DBPR). Contractors are either certified (holding a statewide certificate of competency) or registered (licensed to work in specific jurisdictions). You can verify any contractor's license status through the DBPR's online license search at myfloridalicense.com.

Jacksonville enforces the Florida Building Code 8th Edition (2023). Most HVAC work—including installation and significant repairs—requires a permit from the city's Building Inspection Division before work begins. Permits ensure the work meets code standards and protects your home's safety and resale value. The city accepts online permit submission through JaxEPICS.coj.net.

Before hiring, ask your contractor to provide their license number and confirm it is current and in good standing. Verify the license through the DBPR search tool. Request a written estimate, ask whether permits will be obtained, and confirm the timeline and warranty terms in writing.
