Recommended unit for Greenville
Given Mississippi’s hot-humid climate and electric heating, high-seer2 heat pump is the sensible default for most Greenville 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.
