Naples has one of the most demanding AC climates in the country — 10+ months of cooling, Gulf Coast humidity, and salt air that accelerates corrosion. Here's what Naples homeowners need to know be fore replacing their AC system in 2026.
Collier County Permit Requirements
All AC installations in Naples and Collier County require a mechanical permit through Collier County Growth Management. Permits run $150–$350. Work must be performed by a Florida-licensed HVAC contractor (Class A or B license). Permit inspections are required — don't skip them, especially in Naples where code enforcement is active.

What to Spec for a Naples Home
Minimum 15 SEER2 — Florida state minimum for new installations since January 2023.
16–18 SEER2 recommended — Naples cooling bills run $200–$400/month in summer. Higher efficiency pays back in 3–5 years.
Coated coils — Within 5 miles of the Gulf, salt air corrosion is real. Specify units with treated or coated coils.
4–5 ton capacity — Most Naples homes 1,800–2,500 sq ft need 4 tons. Many older installations are undersized.
