A system that has to work almost year round
In Chatham County, a heating and cooling system only gets a break for about a month a year. Cooling runs May through October, with summer afternoons averaging 91°F, and heat comes on November through March, when winter nights average 42°F. That is 11 months of one system or the other carrying the load.
Most homes here heat with electricity, so the equipment you choose has to handle both jobs well. And it has to keep running through what the coast sends its way. Chatham County has logged 246 damaging wind events over the past ten years, and in 2024, close to a third of Georgia households lost power for a day or more. A new system installed here should be set up with that in mind, not just sized for the heat and cold.

Georgia requires HVAC contractors to hold a state license.
The license is issued to the contractor's business, not to each job it takes on. The State Construction Industry Licensing Board tested this contractor and keeps a record of them, but that record covers the contractor generally. It is not a sign-off on your particular installation.
That sign-off, where it exists, comes from the local building office. In most cities and counties, installing a furnace, air conditioner or heat pump needs a permit, and the work gets inspected once it's done. The license tells you the contractor was tested. The permit and inspection, where your city or county requires them, tell you this particular system was put in correctly.

- 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 the house comfortable through the summer heat and winter cold here. If a contractor is recommending the same repair more than once, or the equipment runs longer and longer to do the same job while your bills climb, that's the system telling you it's done. Summers here push to a 91°F average afternoon and winters drop to a 42°F average night, so a failing system gets tested hard in both directions. A contractor can look at the age and condition of your equipment and tell you whether repair still makes sense.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to replace them together. A furnace and air conditioner installed years apart often don't match well, and mismatched equipment can wear out faster or run less efficiently. Homes here need the furnace November through March and the air conditioner May through October, so both units work hard nearly all year. If one is already failing, a contractor can look at the age and condition of the other and tell you whether it's worth pairing them now or waiting.
- What happens during an HVAC installation?
- A contractor removes the old equipment, checks the ductwork for leaks or sizing problems, and sets the new furnace or air conditioner in place. They connect the refrigerant lines, gas or electrical supply, and ductwork, then run the system through a full cycle to confirm it heats and cools correctly. Georgia requires the contractor doing this work to hold a state license issued by the State Construction Industry Licensing Board. The exact steps and timeline depend on the equipment and the house, so a contractor can walk you through what your installation will involve.
