Five months of real heat, every year

Spartanburg summers run May through September, and afternoons average 88°F across that stretch. That is the load your new system has to carry, day after day, for the better part of five months.

Hail and wind show up here too, 53 hail events and 125 damaging wind events over the last ten years, so an outdoor unit needs to sit through storms and keep running. Any central air conditioner installed new has to meet 14.3 SEER2, the federal efficiency minimum, and sizing it right for a Spartanburg summer matters as much as the rating on the label.

What size air conditioner does my house need?
It depends on a proper load calculation, not the size of your old unit or your square footage alone. A contractor measures your home's insulation, window area, ceiling height, and layout to run this calculation. Too large a unit cools the air fast but shuts off before it pulls the humidity down, and too small a unit runs constantly without keeping up on the hottest afternoons. With summer highs here averaging 88°F over the five months homes need cooling, getting this number right matters for how the house actually feels, not just whether the thermostat reaches its setting.
Should I replace the whole system or just the outdoor unit?
In most cases you replace both the outdoor unit and the indoor coil together. The two are matched to work at a specific efficiency and capacity, and pairing a new outdoor unit with an old indoor coil usually means it never reaches the rating it was built for. It can also void the manufacturer's warranty on the new equipment. A contractor can tell you whether your existing coil and ductwork will work with a new outdoor unit or whether the whole system needs to come out together.
Do HVAC contractors in Spartanburg need a state license to work on my home?
Ask to see a contractor's license number before any work starts on your home. A licensed contractor also carries the insurance that protects you if something goes wrong during the install. If you are not sure a number is valid, a contractor should be able to show you proof without hesitation.
