What your system should be sized for

A heat pump in South Carolina should carry the house on the coldest design day, not the average one. These are the winter design temperatures our engine sizes against, in AHRI heating region III (2,500 heating degree days at the Columbia reference metro).

City	Design temp	Climate zone	Basis
Columbia	24°F	3A	estimated
Charleston	28°F	2A	estimated
Greenville	22°F	3A	estimated

Rebate amounts are estimates and subject to change. Verify current program terms and eligibility before quoting a final net price.
Eligibility varies by income, equipment efficiency, utility territory, and program funding availability.
State and utility programs only. Federal 25C/25D tax credits expired 12/31/2025 and the DOE HEAR/HOMES rebate programs ended 5/29/2026; neither is included.
After-install rebates are claimed by the homeowner after installation and are not guaranteed at the point of sale.
