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.
In hot-humid zone 2A the central air system runs most of the year, and humidity is half the job. An oversized unit cools quickly and shuts off before it dries the air, leaving rooms damp. Ask for a load calculation and a matched air handler. Ask where the condensate line drains and whether it has a safety switch that shuts the unit off if it clogs. Get the SEER2 rating and warranty terms in writing.
