Eleven months of work, most years
A new system in Goose Creek is on the job nearly year round. Summer afternoons average 91°F, and cooling runs May through October, six months straight. Winter is shorter but still real, with nighttime lows averaging 38°F from December through February and heat needed November through March. That leaves only one slow month for the equipment to rest.
Most homes here heat with electricity, so the same system usually carries both jobs. That matters when storms come through. The area has logged 146 damaging wind events over the past ten years, and statewide, 45% of households went at least 24 hours without power in 2024. A system that comes back on by itself once power returns means less time without heat or air while you wait on the rest of the house to reset.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the system is old enough that another breakdown is only a matter of time. A contractor can tell you what shape the furnace or air conditioner is really in and whether it is worth fixing again. Rising energy bills without any other explanation are another sign, since a system loses efficiency as it ages. Homes here need heat or cooling 11 months of the year, so a system that is struggling does not get much of a break to recover.
- Should I replace my furnace and air conditioner at the same time?
- If both are close in age, replacing them together is usually the better move. A furnace and air conditioner installed years apart end up mismatched, and the newer unit has to work around the limits of the older one. Doing both at once also means only one installation instead of two, and a contractor can size the whole system to work as a pair. If one unit still has years of life left in it, a contractor can tell you whether it makes sense to wait or replace both now.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to the existing ductwork, gas line, electrical, and drain lines. They check the ductwork itself for leaks or damage, since new equipment blowing air through bad ducts will not perform the way it should. Once everything is connected, they test the system, check refrigerant levels if it's an air conditioner, and confirm the thermostat is talking to the new equipment correctly. The exact steps and how long it takes depend on the house and the equipment, so a contractor will walk you through what your installation involves.
