Frequently Asked Questions — AC Installation in Fleming Island

What size AC do I need for my Fleming Island home?

In Fleming Island's hot, humid climate, proper sizing is critical. A load calculation (Manual J) is the industry standard. A rough guide: 1 ton per 400–500 sq ft, but Fleming Island's heat and humidity often require slightly more capacity. An undersized system runs constantly; an oversized system short-cycles and leaves you humid.

What SEER rating should I buy in Florida?

Florida requires a minimum 15 SEER2 for new installations. Many Fleming Island homeowners choose 18–20 SEER2 systems for energy savings — with Florida's long cooling season, the efficiency upgrade often pays back in 4–6 years.

How long does AC installation take in Fleming Island?

A standard central AC replacement takes 4–8 hours. New installations requiring ductwork can take 1–3 days. Plan for your home to be warmer than normal during installation.

Do I need permits for AC installation in Clay County?

Yes — Clay County requires permits for AC installation and replacement. Your licensed HVAC contractor will pull the permit and schedule the required inspection. Never skip this step; unpermitted HVAC work can cause insurance and resale issues.
