HVAC Replacement permit in Jacksonville, FL
Yes — you need a permit for hvac replacement work in Jacksonville.
You need a mechanical permit to replace a central air conditioner, furnace, or heat pump. Florida's exempt list skips permits only for portable heaters, portable ventilation, portable coolers, evaporative coolers, self-contained refrigeration units holding 10 pounds or less of refrigerant with motors of 1 horsepower or less, and for replacing a single part that does not change the equipment's approval or make it unsafe. Replacing whole equipment is not on that list. In an emergency the work may go ahead, but the permit application must be filed by the next business day.

If you skip it
