Recommended unit for St. Andrews
Given South Carolina’s hot-humid climate and heat-pump heating, high-seer2 heat pump is the sensible default for most St. Andrews 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.

What St. Andrews code requires
Installing or replacing an HVAC system in St. Andrews follows South Carolina rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum14.3 SEER2 (Southeast)
Federal Southeast-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
South Carolina enforces the IECC-based state energy code with a hot-humid focus; high heat-pump adoption means electric-strip backup sizing and humidity control matter more than cold-climate concerns.
