Ten months of work a year on this system
In Forest Park, heat runs November through March and the AC runs May through September. That is ten months where the system is on, cycling, and wearing down. Winter nights average 35°F, cold enough that the furnace kicks on and off through the night. Summer afternoons average 88°F, so the AC runs hard and long to keep up.
Storms add to the load. Clayton County has seen 38 damaging wind events and 3 winter storms over the past ten years, and across Georgia, close to a third of households lost power for at least a day in 2024. A system that loses power mid-cycle and comes back on under strain is more likely to trip a breaker or stall out than one running on a calm day. When yours won't start, or is blowing air that is not the right temperature, that is often where it started.

Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board tests and licenses HVAC contractors in Georgia, and it keeps the record of who holds that license. The license belongs to the contractor, not to the job, so it does not get reissued each time someone takes on a new repair.
For a heating and cooling repair in Clayton County, that license is what stands behind the person working on your system. It means the state has tested this contractor and has a record of who they are.

- Why is my heat not working?
- Most no-heat calls come down to a thermostat set wrong, a dead breaker, a clogged filter, or a failed igniter on a gas furnace. Check the thermostat is set to heat and a few degrees above room temperature. Check the breaker panel for anything tripped. If the furnace turns on but blows cold air or shuts off after a few minutes, that points to the igniter or flame sensor, and a licensed contractor will need to look at it.
- Why is my system running but not cooling the house?
- If the blower is running but the air is not cold, the problem is usually the filter, the outdoor unit, or the refrigerant charge. Start with the filter. A filter clogged with dust blocks airflow across the indoor coil, and the coil can ice over, which stops it from cooling at all. Next, go outside and check that the condenser unit is running and the fan is spinning. If the filter is clean and the outdoor unit is running but the house still is not cooling down, the system likely needs a licensed contractor to check the refrigerant charge.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to heat or cool as needed, the batteries are good, and the temperature setting is actually higher or lower than the room. Next check the breaker panel for a tripped breaker, and check the filter, since a filter packed with dust can stop a system from heating or cooling properly. If the outdoor unit is not running at all, look for a tripped breaker or a switch nearby that may have been bumped off. Anything beyond that, like strange noises, burning smells, or water pooling near the unit, is worth telling the contractor when they come out. It helps them get to the problem faster.
