Eleven months of work a year in Stonecrest
A new system here runs almost year round. Winter nights average 35°F from December through February, and summer afternoons average 88°F, so the unit you install has to handle both a real heating load and a real cooling load, not just one or the other. Homes need heat November through April and cooling May through September. That leaves one slow month, and even that is not a guarantee.
Most homes in the area heat with gas, so the furnace and the air conditioner or heat pump paired with it both matter to the install. And with almost a third of Georgia households losing power for 24 hours or more in 2024, and 132 damaging wind events recorded here over the past ten years, it is worth asking your contractor how the new system handles a power outage before it is in the ground.

Georgia requires HVAC contractors to hold a state license.
The state board tests the contractor and keeps that license on file. It covers the contractor, not any single job. Georgia issues it through the State Construction Industry Licensing Board.
For this installation, the license tells you the contractor was tested and is on record with the state. What checks the job itself is the permit. Putting in a new furnace, air conditioner or heat pump needs a permit from the local building office in most cities and counties, and the work gets inspected once it's done.

- 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 on the coldest nights or hottest afternoons anymore. Most furnaces and air conditioners last a decade or two, but the age isn't the real test. If you're calling for repairs every year, or if a repair bill runs close to what a new unit would cost, that's the sign. Homes here run heat or cooling most of the year, from November through April and again from May through September, so a system that's struggling has almost no season to rest and recover.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at different times can still work fine side by side as long as they're matched to each other and to your ductwork. If one has failed and the other is still young, a contractor can tell you whether pairing a new unit with the old one will work or whether it's better to do both now. That decision comes down to the specific equipment in your house, not a rule that applies everywhere.
- 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'll check that the ducts are sized right for the new equipment, since a mismatch there hurts performance no matter how good the unit is. Once it's connected, they test it under a full heating or cooling cycle and check refrigerant charge, airflow, and any safety controls before they consider the job done. A licensed contractor is required for this work in Georgia, and the license comes from the State Construction Industry Licensing Board.
