Spartanburg asks for heat and cooling both, almost every month of the year
Winter nights here average 33°F from December through February, and homes run heat seven months of the year, October through April. Summer afternoons average 88°F, and cooling runs the other five, May through September. That is twelve months where a system is doing one job or the other, with barely a break between.
A new furnace or heat pump has to handle that winter cold, and a new air conditioner or heat pump has to handle that summer heat, sized for both. Power matters too. Most homes here heat with electricity, and in 2024 nearly half of South Carolina households lost power for at least a day. Spartanburg County has seen 125 damaging wind events over the past ten years. A system that comes back on by itself once the power returns is worth knowing about before the next storm, not after.

- When should I replace my HVAC system?
- Once your furnace or air conditioner needs a repair and it is already old, replacement is usually the better move. Watch for signs it's struggling. It runs longer to reach the same temperature, your energy bills climb without a clear reason, or a contractor has already been out more than once in the past year or two. Homes here need heat or cooling every month of the year, so a system on its last legs does not get much of a break to recover. If the repair costs a large share of what a new system would, that is usually the point to stop patching it.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often worth considering, but it depends on the condition of each one, not just its age. A furnace and air conditioner installed at different times can still work fine together as long as they are matched correctly. Where it matters most is when one has failed and the other is close behind. Winters here run October through April and summers May through September, so there is no long stretch where either system sits idle, and a mismatch or a failing partner unit shows up fast. A contractor can look at both and tell you whether pairing the replacement makes sense for your setup.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to your ductwork, refrigerant lines, electrical, and where needed, gas or a condensate drain. They check the ductwork for leaks or sizing problems, since a new system connected to bad ducts will not perform the way it should. Once it's running, they test it, check refrigerant charge and airflow, and confirm the thermostat is working with the new equipment. Storms knock out power often enough here, with 125 damaging wind events recorded over the past ten years, that it's worth asking whether your new system will restart on its own once power comes back.
