What a new system in Carrollton has to handle
Homes here need heat from October through April and cooling from May through September, so the system runs one way or the other all year. Winter nights average 34°F, and summer afternoons average 88°F. A new furnace or heat pump has to hold up through both.
Most homes in the area heat with electricity, which means the system depends on the power staying on. Across Georgia, 31% of households lost power for at least 24 hours in 2024, and the county has recorded 87 damaging wind events over the past ten years. That is worth asking about when you are choosing what to install and where the outdoor unit goes.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board issues that license to the contractor, and it covers the business, not the specific job. The board has tested the contractor and keeps a record of them, but nobody from the state comes to your house to check the work.
That check comes from the local building office. In most cities and counties, installing a new furnace, air conditioner or heat pump needs a permit, with an inspection once the work is done. The license tells you the contractor was tested and is on record with the state. The permit and inspection are what confirms the equipment in your home was installed correctly.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth, or when the system can no longer keep the house comfortable through the summer heat and winter cold here. If your system is old and just had a major part fail, like the compressor or heat exchanger, that's usually the point where replacing makes more sense than repairing again. An aging system also tends to break down more often and cost more to run than a new one. Homes here need heating or cooling every month of the year, so a system on its last legs won't get much of a break to buy you time.
- Should I replace my furnace and air conditioner at the same time?
- If both units are close in age, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time work as a matched system, and pairing an old furnace with a new air conditioner, or the reverse, can mean one part limits how well the other performs. If only one has failed and the other is still fairly young, a contractor can install just that one and connect it to what's already there. The right call depends on the age and condition of each unit, which is something a contractor can assess for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to the ductwork, gas line or electrical circuit, and refrigerant lines. They check the ducts for leaks or sizing problems, since a new system can't perform right if the ducts feeding it are the wrong size. Once everything is connected, they test the system, check refrigerant charge, and confirm it's heating and cooling the way it should. In most cities and counties here, this work needs a permit from the local building office and an inspection when it's done.
