Recommended unit for Florence
Given South Carolina’s hot-humid climate and heat-pump heating, high-seer2 heat pump is the sensible default for most Florence 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 Florence code requires
Installing or replacing an HVAC system in Florence 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.

AC Maintenance in Florence, explained.
What Affects Tune-Up Costs in Florence?
Labor rates in Florence reflect a smaller market, but permit fees and code compliance can add to the cost. Older homes (median built 1980) may need extra time to clean coils or check ductwork. Heat pumps are common here, and tune-ups for them may include checking electric-strip backup and humidity settings. Adding a coil cleaning or enrolling in an annual plan (two visits for $125–$300) can lower the per-visit cost.
Common AC Issues in Florence Homes
Frozen Evaporator Coils
Due to high humidity and older systems, coils can ice up if airflow is restricted or refrigerant is low.
Refrigerant Leaks
With R-410A being phased out, older units may develop leaks; tune-ups check pressure and recommend upgrades if needed.
Dirty Condenser Coils
Outdoor units in Florence's humid climate collect debris and pollen, reducing efficiency and causing high head pressure.
