Stockbridge asks a lot of both sides of the system

Ten months out of the year, a heating and cooling system in Stockbridge is working. Heat from November through March, cooling from May through September, and only a couple of months where it gets to rest. Winter nights average 35°F, mild compared to the north, but summer afternoons hit 89°F, and that side of the system runs just as hard as the furnace does.

A new install here has to be sized for both jobs, not just the one that's easiest to picture. Half of homes in the area heat with gas, and whatever you choose, it has to meet the federal minimum efficiency rating in place at installation. Storms are part of the picture too. Henry County has logged 50 damaging wind events over the past ten years, and in 2024, 31% of Georgia households lost power for 24 hours or more. Worth asking about a system that comes back on by itself when the power does.

Georgia requires HVAC contractors to hold a state license.

The State Construction Industry Licensing Board tests and records the contractor, not the individual job. The license tells you the person or company taking on this installation had to prove they knew the trade before Georgia let them work in it. It does not follow them room to room once they are hired.

For an installation like this one, most cities and counties in Georgia require a permit before the work starts and an inspection once it is done. That inspection is what checks the actual installation, the wiring, the venting, the refrigerant lines, not the license. The license tells you who is allowed to do the work. The permit and inspection tell you whether this particular job was done right.

When should I replace my HVAC system?
Replace it when repairs start happening every year, or when a repair costs a large share of what a new system would cost. Age matters too. An older furnace or air conditioner works harder to keep up than a newer one does. Homes here need heat or cooling 10 months of the year, so that wear adds up faster than it would somewhere milder. A contractor can look at the specific unit and tell you whether it is worth another repair or not.
Should I replace my furnace and air conditioner at the same time?
If they are close in age, replacing both at once usually makes sense. A furnace and air conditioner installed together are matched to work as one system, and pairing an old unit with a new one can mean the new one never runs at its rated efficiency. If your furnace is failing but the air conditioner still has years left, a contractor can replace just the furnace and match it correctly. Just over half of homes here heat with gas, so this comes up often when a gas furnace and electric air conditioner share the same ductwork.
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, gas line or electrical circuit, and condensate drain. They check the refrigerant charge, test the gas connection or wiring, and run the system through a full cycle to confirm it heats or cools correctly. On a full system replacement, this usually includes checking that the ductwork and vents are sized right for the new equipment, not just swapping the old boxes for new ones. The exact steps depend on what you're replacing and what the house already has, so a contractor will walk through the specifics for your setup before starting.
