14.9¢/kWh

Your Electricity Rate

This is what you pay per kilowatt-hour of electricity through Berkeley Electric Coop Inc. It matters because a heat pump runs on electricity — so your electric rate directly affects how much it costs to heat and cool your home. Your rate is near average, so a mid-efficiency system (16–18 SEER2) usually offers the best balance of upfront cost and energy savings.

What's SEER2? It stands for Seasonal Energy Efficiency Ratio — think of it like MPG for your car. A 20 SEER2 system uses about 25% less electricity than a 15 SEER2 system. At Mount Pleasant's rate, that's roughly $255/year saved on heating alone.

It's ideal if you don't have existing ductwork, or want to control temperatures room-by-room. In South Carolina: Ducted median $8,182 vs Ductless Mini-Split median $28,000.
