Twelve months of run time wears on a system here
Your system in Carrollton does not get an off season. It heats from October through April, then switches over and cools from May through September. That is twelve months of work a year, with almost no rest in between.
Winter nights averaging 34°F mean the furnace cycles on and off most of the night, and each start puts strain on the igniter or the ignitor board. Summer afternoons averaging 88°F push the compressor hard for five straight months, and a system that never gets a real break tends to show weak parts sooner rather than later. Add in 87 damaging wind events over the past ten years, and it is not just wear from heat and cold. Storm damage to the outdoor unit or a power interruption can knock out a system that was already running on borrowed time. With 58% of homes here heating with electricity, a power outage means no heat at all until the power and the system both come back.

Georgia requires HVAC contractors to hold a state license.
Georgia's license comes from the State Construction Industry Licensing Board. It belongs to the contractor, not to any single job. The same license covers them whether they're working on a furnace, an air conditioner, or a system that does both.
For a repair like this, that license is what the contractor is accountable under. It doesn't get reissued per job, so the license you see is the one that applies to the work being done on your system today.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and the temperature is set above the room temperature, since a cooling call left on will keep the furnace off. Check the breaker and the furnace switch, which looks like a regular light switch near the unit. If the furnace has a standing pilot, see if it went out. If power and gas are both fine and it still will not fire, the igniter or a safety switch is likely the problem, and that calls for a contractor.
- Why is my system running but not cooling the house?
- Check the filter first. A clogged filter blocks airflow across the coil, and on a hot afternoon near 88 degrees the house will not catch up. Check that the outdoor unit is not covered in leaves or debris and that the breaker for it is on. If the filter is clean and air is moving but still not cold, the system is likely low on refrigerant or has a failing part, and that needs a contractor with gauges to find out.
- What can I check before calling for HVAC repair?
- Check the thermostat batteries and settings first, since a dead battery or a wrong mode explains a lot of no-heat and no-cool calls. Check the breaker for the unit and, for a furnace, the switch that looks like a light switch near it. Look at the filter and replace it if it is dirty. If the outdoor unit will not run, make sure nothing is blocking it. After a storm, if the power was out for a while, give the system a few minutes after power returns before deciding it is broken, since most systems restart on their own.
