The Jacksonville market
Jacksonville's Building Inspection Division exempts only small plumbing swaps such as faucets, and its exemption list expressly excludes water heaters, so a water heater replacement needs a permit. For HVAC, only replacing a part inside a single piece of equipment is exempt. Homeowners can pull permits in person at 214 N. Hogan St., Room 280, and any contractor you hire must pull their own trade permit. Fees were not confirmed. Under Florida Statute 553.80(3)(b), owners replacing electric HVAC equipment in a one- or two-family home can request an inspection exemption when the total cost stays under $5,000; the notarized form has no fee. DOE puts Duval County in hot-humid climate zone 2A, and EIA's 2020 survey found 90% of Florida homes have central air and 66% heat with electricity.
Heating is a short season in climate zone 2A. Only 5% of Florida homes heat with natural gas while 33% list a furnace, which means most Florida furnaces are electric air handlers with resistance heat strips. Those strips cost a lot to run on the few cold nights they work. When the air handler is paired with an aging AC, price a complete heat pump system as an alternative, since it heats for far less.
