What Peachtree City weather asks of a new system
Ten months out of the year, a heating and cooling system in Peachtree City is doing something. Winter nights from December through February average 35°F, mild enough that a heat pump can carry the load without much help. Summer afternoons average 89°F for five months, May through September, so the cooling side works about as hard as the heating side does.
Most homes here heat with gas, but whatever fuel a new system uses, it needs to be sized for both seasons, not just one. Wind is the bigger risk to plan around. Fayette County has logged 72 damaging wind events over the past ten years against just 2 winter storms, and in 2024 nearly a third of Georgia households lost power for 24 hours or more. A new installation is worth pairing with a plan for what happens to heat and hot water when the power goes out, not just what happens when the weather turns.

Georgia requires HVAC contractors to hold a state license.
Georgia's license is held by the contractor, and it covers the contractor rather than any one job. The State Construction Industry Licensing Board keeps the record of who holds it, so the same license is what stands behind this installation as stands behind every other job that contractor takes on.
For a system installation, most cities and counties also expect a permit from the local building office, with an inspection once the work is done. That permit is separate from the state license. It is the local check that this furnace and this air conditioner, in your house, were put in correctly.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when parts are getting hard to find for it, or when it can't keep up on the coldest nights or hottest afternoons anymore. Age matters too. An older furnace or air conditioner working hard is a candidate even if it's still limping along, because it runs less efficiently than a new one would and the parts most likely to fail get harder to source. Homes here need heat from November through March and cooling from May through September, so there isn't much of the year where a failing system goes unnoticed. If yours is struggling now, that's usually the sign, not the calendar.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, yes, it usually makes sense to do both together. A furnace and air conditioner installed at the same time are matched to work as a system, and replacing one while keeping an old one around can mean the new part is held back by the old one, or that a mismatch causes problems down the line. It also means one visit from the contractor and one inspection instead of two. That said, if one unit is much newer than the other, a contractor can look at both and tell you honestly whether it's worth replacing the working one now or waiting.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to the ductwork, the gas or electrical line, and the refrigerant lines. They'll check the ductwork itself for leaks or sizing problems, since even good equipment won't perform right if the air can't move through the house properly. Once everything's connected, they test the system, check refrigerant charge and airflow, and walk you through the thermostat and any new controls. In most cities and counties here, this job needs a permit from the local building office and an inspection once the work is done, so the contractor should handle that as part of the job.
