What Newnan winters and summers ask of your system

Your new system will run ten months out of the year here. Heat from November through March, cooling from May through September, with barely a break between. Winter nights average 35°F, so the furnace or heat pump isn't fighting extreme cold, but it still needs to hold steady for five straight months. Summer afternoons average 88°F, and the air conditioner carries that load for five months too.

More than half the homes in the area heat with electricity, which means the heat pump or furnace is doing real work on the power grid during those cold nights. And the power itself isn't always reliable. Nearly a third of Georgia households lost power for at least 24 hours in 2024, and Coweta County has seen 174 damaging wind events over the past ten years. A new installation should account for that, not just the temperature swings.

Georgia requires HVAC contractors to hold a state license.

Georgia licenses HVAC contractors through the State Construction Industry Licensing Board. That license belongs to the contractor, not the job, so the same license covers a company across every install it does, not just this one.

For the installation on this page, that license is what stands behind the person doing the work. In most cities and counties, a new furnace or air conditioner also needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from the state license, and it is what catches a bad connection or a wiring mistake on this particular job.

When should I replace my HVAC system?
Replace it when repairs start costing more than they're worth or when the system can't keep up anymore, whichever comes first. Watch for signs like short cycling, rooms that never reach the temperature you set, or a technician telling you the same part keeps failing. Age matters too. A furnace or air conditioner working hard for 5 months of heat and 5 months of cooling every year here wears faster than one that idles most of the year, so a system in its second decade deserves a hard look even if it still runs.
Should I replace my furnace and air conditioner at the same time?
If they're close in age, yes, that's usually the better time to do it. Replacing both at once means the coil and the furnace are matched to work together, and a contractor only has to open up the ductwork and line set once. If one is much newer than the other, there's less reason to rush the second one out early. A contractor can look at the age and condition of each piece and tell you whether pairing them makes sense for your house.
What happens during an HVAC installation?
A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, usually keeping the ductwork if it's sized right for the new system. They run the refrigerant lines, connect the electrical and gas or power supply, and check the ductwork for leaks or restrictions before closing it back up. Once everything is connected, they test the system through a full heating and cooling cycle, checking refrigerant charge, airflow, and that the thermostat is talking to the equipment correctly. With winter lows here averaging 35°F and summer afternoons near 88°F, that testing step matters. The system needs to prove it can handle both ends of the year before the job is called done.
