AC installation cost by system.
Installed pricing for Lake Mary, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Lake Mary, Florida, AC installation costs typically range from $3,700 to $7,500 for a like-for-like central AC replacement, and $5,600 to $12,200+ if new ductwork is needed. Ductless mini-splits run $2,800–$7,500, while heat pumps—recommended for this hot-humid climate—cost $4,700–$11,200+. Because most homes were built around 1996, many systems are nearing the end of their lifespan, and Florida’s building code requires hurricane tie-downs for outdoor units, adding to labor and materials. Permits and Manual J load calculations are mandatory, and the shift to R-454B or R-32 refrigerant (R-410A phased down) may affect equipment availability and pricing.

Recommended unit for Lake Mary
Given Florida’s hot-humid climate and heat-pump heating, high-seer2 heat pump is the sensible default for most Lake Mary homes. With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.
