Heating in Charleston is mostly a heat pump story. EIA's 2023 state data shows about 71% of South Carolina households heat with electricity and about 23% with natural gas, so many local homes have no furnace burner at all. Winters are short, with occasional freezes, which means a system can sit unused or run hard all summer and then get tested on one cold night.

Heating service in Charleston: start with your system
First work out what you own, then match the problem.
- Gas or electric furnace, not heating. Book furnace repair. If you smell gas, leave the house, then call your gas utility's emergency line or 911. If a CO alarm sounds, get out and call 911.
- Heat pump iced over, weak or running up the bill. Heat pump repair covers defrost boards, frozen coils and auxiliary heat strips.
- Furnace still runs and winter is coming. A fall furnace maintenance visit checks the burners, flue and safety controls.
- Old furnace with a failed part or a cracked heat exchanger. Compare a repair with furnace replacement.
- No heat in the space, or a new build. Furnace installation and heat pump installation each suit different homes.
Which heating system fits a Charleston home?
For most all-electric homes, a heat pump. It cools through our long summer and handles a short winter, with electric strips for freezes. Near salt water, plan for coil care, since the outdoor unit runs year-round. A gas furnace still fits where service already reaches the house. Furnaces and air handlers often sit in attics or closets here, so ask about access before you compare quotes.
We quote before work begins, and we will tell you when a repair is the better call.

Questions about this service
How do I know if I have a furnace or a heat pump?
Look outside in cold weather. If the outdoor unit runs while the heat is on, you most likely have a heat pump. A metal or plastic flue and a gas line at the indoor unit point to a gas furnace. Around Charleston, the model number on either unit also settles it, and we can help you read it over the phone.
What should I do if I smell gas or my CO alarm sounds?
Leave first. For a gas smell, go outside without touching switches and call your gas utility's emergency line or 911. If a carbon monoxide alarm sounds, get everyone out and call 911. Our guide on smelling gas near a furnace covers the steps. Call a technician once the house has been cleared.
Do I need heat service if winters here are so mild?
Yes, because occasional freezes still arrive, and a system that has sat unused or worked hard all summer can fail on the first cold night. A fall check lets you find problems ahead of the rush. Heat pumps run year-round here, so they take wear in both seasons, and gas furnaces need a yearly safety check.
How do I check a heating contractor?
Start with the SC LLR lookup: request a license number from any contractor and run it there. Then read recent reviews and get the scope in writing. Our guide on the heat pump or furnace choice also helps you compare what each bidder recommends for a home around here.
