Naples is a very high cost-of-living market — pricing guide and permit rules below.
Naples hvac rates: $5,000-$18,000 per system. Naples's humidity and storms make regular maintenance essential. Always get 3 written quotes and verify FL licensing at Florida DBPR (myfloridalicense.com). Sales tax on materials: 7%.
Naples requires permits when work exceeds $500 or involves full system replacement. Your licensed contractor pulls the permit — if they ask you to pull it, that's a red flag.
