Fulton County runs its system nearly all year
Your system works eleven months out of the year here. Heat from November through April, cooling from May through September. There's barely a month where something inside isn't running.
Summer afternoons averaging 88°F keep the compressor working hard for five straight months. Winter nights averaging 35°F mean the burner or heat strips cycle on and off through the coldest hours, and each start puts a little more strain on the igniter or the contactor. Storms add to the load too. Georgia has seen 10 winter storms and 162 damaging wind events over the past ten years, and in 2024, 31% of households in the state lost power for at least 24 hours. A system that loses power mid-cycle and comes back on wrong often shows it the next time you reach for the thermostat.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board is the body that tests and licenses HVAC contractors in Georgia. The license belongs to the contractor, not to any single job, so it does not get reissued for the repair at your house. It is the record the board already holds of who that contractor is and what they were tested on.
For a repair on your heating and cooling system, that license is what stands behind the person doing the work. It covers the contractor's standing to do HVAC work in Georgia, not the specifics of this repair.

- Why is my heat not working?
- Start with the thermostat. Make sure it's set to heat and the temperature is set above room temperature, since a setting bumped a degree or two can look like a dead system. If that's not it, check the breaker for the furnace and, on a gas furnace, make sure the switch that looks like a light switch near the unit is on. That switch cuts power to the furnace and gets flipped by accident more often than people expect. If the furnace runs but blows cold air, or won't turn on at all, it needs a contractor to look at it. Winters here run November through April, so this isn't something to leave for long.
- 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 air can't move past it the coil can ice over, which stops cold air from reaching the house even though the system is running. Check that the thermostat is set to cool, not fan only. Outside, make sure the outdoor unit isn't blocked by leaves, grass clippings, or anything pressed up against it, since it needs open airflow to release heat. If the filter is clean and the outdoor unit is clear and you're still getting warm air, the system needs a contractor to check refrigerant levels and the coil itself.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it uses them, and the breaker for the system. These catch a surprising number of no-heat and no-cool calls. Next check the air filter. A filter that's dirty enough to block airflow can cause problems on both the heating and cooling side. If you have a gas furnace, check that the power switch near the unit, the one that looks like a standard light switch, is switched on. After a storm, check that the outdoor unit isn't covered in debris or sitting in standing water. If you've checked all of this and the system still isn't working right, a licensed contractor can diagnose it. Georgia requires HVAC contractors to hold a state license, so it's worth confirming that before they come out.
