AC Installation & Replacement in Florida — New AC Unit

Whether your current AC system has finally given up after 15+ years of Florida heat, or you're building a new home and need a system sized correctly for our subtropical climate, choosing the right AC installation matters. An undersized unit will run constantly and never cool your home. An oversized unit will short-cycle, waste energy, and fail to dehumidify. Our licensed Florida HVAC installers perform a Manual J load calculation to size your system perfectly, then install it to manufacturer specifications with a full warranty.

Signs You Need a New AC System

System is 15+ years old — average AC lifespan in Florida is 10-15 years (shorter than northern states due to year-round use)
Uses R-22 refrigerant (Freon) — phased out, increasingly expensive to recharge ($100+/lb)
Repair costs exceeding 50% of a new unit — diminishing returns on old equipment
Energy bills keep climbing — older systems lose efficiency over time
Uneven cooling throughout your home — system can no longer keep up with demand
Frequent breakdowns — 2+ service calls per year = time to replace

AC Installation & Replacement — Frequently Asked Questions

How much does a new AC cost in Florida?

A complete AC system (air handler + condenser + installation) costs $3,500–$10,000 in Florida depending on home size, brand, and efficiency rating. The most common replacement for a 3-ton system is $4,500–$6,500. Financing with 0% APR is available.

What size AC do I need for my Florida home?

Florida homes typically need 1 ton of cooling per 400-500 square feet. A 2,000 sq ft home usually needs a 4-ton system. However, proper sizing requires a Manual J load calculation that accounts for insulation, windows, duct condition, and orientation. Our installers perform this calculation free of charge.

How long does AC installation take?

A straightforward replacement (same location, same size) takes 4-8 hours — typically completed in one day. If ductwork modifications, electrical upgrades, or a different location are needed, it may take 2 days.

What SEER rating should I get in Florida?

In Florida, we recommend a minimum SEER2 15 (the new federal standard as of 2023). For maximum savings, SEER2 16-20 systems save $200-$500/year on electricity. The payback period for a high-efficiency unit in Florida is typically 3-5 years — much faster than in cooler climates.
