Hall County runs its system almost year round
Heat runs October through April here, then cooling takes over for May through September. That leaves almost no season where the system just sits idle. On winter nights averaging 34°F the furnace cycles on and off most of the night, and in summer, when afternoons average 87°F, the AC is working just as hard to keep up. Parts that start and stop that often wear faster than they would somewhere milder.
Most homes in the county heat with electricity, so when the power goes out, heat goes with it. Hall County has seen 8 winter storms and 78 damaging wind events over the past ten years, and statewide, close to a third of households lost power for a full day or more in 2024. A system that already runs hard most of the year has less room to absorb a hit like that.

Georgia requires HVAC contractors to hold a state license.
The license comes from the State Construction Industry Licensing Board. It belongs to the contractor, not to any single job, so it does not get issued fresh for your repair. It's the contractor's standing, carried from job to job.
For a repair on your heating and cooling system, that license is what stands behind the person working on your equipment. It covers the contractor doing the work, not a separate check on this particular repair.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and set a few degrees above room temperature, and check that the batteries are not dead. If that is fine, look at the breaker panel. A tripped breaker will shut the whole system down, and with winter nights here averaging 34°F, a furnace that trips its breaker repeatedly needs a contractor to look at it rather than a breaker reset over and over. If the breaker is fine and the thermostat is calling for heat but nothing happens, the igniter or the flame sensor is a common failure point, and that is a repair, not something to troubleshoot further on your own.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the indoor coil, and when that happens the coil can ice over, so the system runs but the air coming out feels weak or even warm. Next check the outdoor unit. If the outdoor fan is not turning or the unit is caked in leaves and debris, it cannot reject heat and the house will not cool no matter how long it runs. If the filter is clean and the outdoor unit looks normal but the house still is not cooling, the system likely needs refrigerant checked by a licensed contractor, since handling refrigerant is not a homeowner job.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it, and the breaker for the system. Check the air filter and replace it if it is dirty, since a blocked filter causes problems that look like bigger failures. Look at the outdoor unit if you have one and clear away any leaves, grass clippings or debris around it. If you have done all this and the system still is not heating or cooling right, a licensed contractor can diagnose what a filter and a breaker cannot fix.
