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.

What Affects Tune-Up Costs in St. Andrews
Pricing varies based on system type—heat pumps may require additional checks on electric-strip backup and defrost cycles. Older homes (median built 1977) often need more extensive cleaning and part replacements. Permit fees, if required, add to the cost. The federal 25C tax credit (30% up to $2,000 for qualifying heat pumps) can offset upgrades, but not routine maintenance.
Common AC Issues Found During Tune-Ups
Dirty Coils
In St. Andrews' humid climate, condenser and evaporator coils accumulate dirt and mold, reducing efficiency and airflow.
Refrigerant Leaks
Older R-410A systems may develop leaks; newer R-454B or R-32 units require proper handling and permit for repairs.
Faulty Capacitors
Heat and humidity cause capacitors to fail, leading to hard starts or compressor failure.
