Generic cost pages skip the things that actually decide your price and which system fits here — local code, climate, and the money you can claim back.
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.
