Oconee Countyand nearby
Heating and air for homes across Oconee County, SC, from Seneca and Walhalla to the Lake Keowee shore, plus Clemson, Central and Pendleton next door.
What makes heating and air different in Oconee County?
Three things: most homes heat with electricity, one in five is a manufactured home, and the land climbs from the lakes to the Blue Ridge.
Around Seneca and Clemson, summers bring about 55 days a year at 90°F or hotter, and the air stays wet off Lake Keowee and Lake Hartwell. That makes humidity control as important as cooling. Up toward Walhalla, Long Creek and Salem, the same heat pump faces more cold nights and less cooling: Walhalla records about 79 nights a year at freezing or below, against 57 at Clemson.
What heats most homes here?
Heat pumps. About seven in ten Oconee County homes heat with electricity, and South Carolina has more than three times the national share of homes heated mainly by a heat pump.
Natural gas from Fort Hill reaches the towns, so many homes in Seneca, Walhalla and Westminster have a gas furnace with central air. Out of town, propane is common: nearly one in ten county homes heats with it. See heat pump and furnace repair for the common winter faults.
Which utility serves you, and what rebates apply?
It depends on the address: Duke Energy, Blue Ridge Electric Co-op, Seneca Light & Water inside Seneca, or the City of Westminster’s own utility.
Duke’s Smart $aver program pays $350–$900 on a qualifying heat pump through a participating contractor. Blue Ridge offers a heat pump loan repaid on the power bill. The full list is in the 2026 rebates guide.
Which towns have their own page?
Clemson, Walhalla, Westminster, Pendleton, Central with Six Mile, and Lake Keowee with Salem. Seneca’s is the home page.
