A system that runs eleven months a year here
Douglasville only gets a real break from its heating and cooling system for about a month out of the year. Winter nights average 34°F from December through February, and summer afternoons average 88°F. That means a furnace or heat pump working November through April, then an AC picking up right after for May through September.
More than half the homes here heat with gas, so a new furnace has to be sized to those winter nights, not just the mild days around them. On the cooling side, any new AC or heat pump sold today has to meet the federal SEER2 minimum, which sets the efficiency floor but leaves the sizing and installation to get the rest right. Georgia also sees its share of power loss, with 31% of households going at least a day without it in 2024, and Douglas County has logged 122 damaging wind events over the past ten years. A new system installed well should be able to come back on its own once the power does.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board issues that license. It covers the contractor, not the specific job.
For an installation, the license tells you the state tested this contractor and holds a record on them. It does not sign off on the finished work. That comes from the local building office. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit, and the job gets inspected once it is done. That inspection is what confirms the system was installed correctly.

- When should I replace my HVAC system?
- Once a furnace or air conditioner is old enough that repairs keep coming back, replacing it makes more sense than paying for another fix. Rising energy bills, uneven temperatures room to room, or a system that runs constantly without keeping up are all signs the equipment is wearing out rather than just needing a repair. Here the furnace works November through April and the air conditioner works May through September, so a system that struggles in either season is working most of the year. A contractor can look at the age and condition of your specific system and tell you whether repair or replacement is the better move.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is often worth considering, but it depends on the condition of each one. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so if your furnace is failing and your air conditioner is close behind it, doing both now can mean avoiding a second installation a year or two later. They also share the same ductwork and, in many systems, the same indoor coil, so matching them up correctly matters for how well the whole system runs. A contractor can check both systems and tell you honestly whether one needs to go or both do.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace and or air conditioner in place, and connects it to your ductwork, electrical, gas line, and refrigerant lines as needed. They check that the ductwork is sized right for the new equipment, since a system that does not match the ducts will not heat or cool evenly. Once everything is connected, the contractor tests the system to confirm it is running properly before finishing up. In Georgia, any contractor doing this work is required to hold a state license issued by the State Construction Industry Licensing Board.
