Ten months of work a year
Greenwood asks a new system to run heat and cooling both, ten months out of the year. Winter nights average 35°F from December through February, and summer afternoons run near 90°F from May through September. A new furnace or heat pump has to carry five months of heat, then five months of cooling, with little rest between.
More than two-thirds of homes here heat with electricity, so a heat pump or electric furnace carries that full winter load on its own. And with 45% of South Carolina households losing power for at least 24 hours in 2024, a system that comes back on by itself once power returns is worth asking about when you install new.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, the unit is old, or it can no longer keep the house comfortable through the swing from 35°F winter nights to 90°F summer afternoons. If a contractor has already been out more than once this year, replacement usually costs less over time than another repair. Homes here need heat or cooling 10 months out of the year, so a system that's struggling has little time to rest and recover.
- Should I replace my furnace and air conditioner at the same time?
- If both units are close in age, replacing them together often makes sense, since they're built to work as a matched pair. A furnace and air conditioner installed years apart may not communicate as well, and mismatched capacity can wear down the newer unit faster. That said, if one system is still young and running well, a contractor can replace just the failing one. A contractor looking at both units can tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, checks the ductwork and electrical connections, and sets the new furnace, air conditioner, or heat pump in place. They connect the refrigerant lines or gas line, wire the system to the thermostat, and test it under a full heating and cooling cycle before finishing. Any duct leaks or sizing issues usually get addressed at this point, since they affect how well the new equipment performs. Since most homes here heat with electricity, a contractor will also confirm the electrical panel can handle the new system's load.
