Ten months of work, most years
Stockbridge only gets a couple months off from heating or cooling. Summer afternoons average 89°F, so the air conditioner runs hard from May through September. Winter nights average 35°F from December through February, cold enough that the furnace or heat pump is cycling on through most of the night, five months running.
That much runtime wears on the parts that start the system up, the igniter or the heat pump's defrost control, more than the parts that just keep it running. Wind is the other thing to watch here. Henry County has logged 50 damaging wind events over the past ten years, enough to knock loose an outdoor unit's wiring or tip a disconnect box. With close to a third of Georgia households losing power for a full day at some point in 2024, a system that does not come back on by itself once power returns can leave a home without heat or air longer than it should.

A new furnace and air conditioner would cut about $170 a year off heating and cooling for a typical Henry County home.
Estimates for a typical Henry County home, compared with an older unit built to the previous federal minimum, from EIA household energy data, Georgia fuel prices and NOAA climate normals. Your home will differ.
Repair makes sense when one part has failed.
Replacement makes sense when the furnace's heat exchanger is cracked, the air conditioner's compressor has failed, or repairs keep coming.
Georgia requires HVAC contractors to hold a state license.
The State Construction Industry Licensing Board tests HVAC contractors in Georgia and keeps their license on file, and that applies the same way in Henry County as anywhere else in the state. The license belongs to the contractor, not to the job, so the person who repairs your system is working under the same license they would need to install one.
For a repair on your heating and cooling system, that license is what stands behind the work. The contractor was tested by the board and can be checked against its records if something goes wrong. Georgia puts that accountability on the contractor's license itself.

- Why is my heat not working?
- The most common reason is the thermostat, the power supply, or the igniter, and each one points to a different fix. If your system runs on gas, a pilot light that will not stay lit or an igniter that will not glow usually means the flame sensor needs cleaning or the igniter has failed. If nothing comes on at all, check the breaker first, since a tripped breaker or a switch left off will stop the whole system cold. With winter nights here averaging 35°F, a furnace that is not heating is worth having looked at quickly rather than waiting it out.
- 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 low refrigerant, a frozen evaporator coil, or a dirty air filter restricting airflow. A clogged filter makes the coil work harder and can cause it to ice over, which cuts cooling even though the fan keeps moving air. Low refrigerant means a leak somewhere in the line, and that is not something to top off and ignore, since it will keep dropping. On a 89°F afternoon here, a system that is running nonstop without cooling is losing ground, not holding steady, so it is worth having a contractor check it before the next hot stretch.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set to heat or cool as needed and that the batteries are not dead. Next, check the air filter, since a filter clogged with dust can choke airflow enough to stop a system from heating or cooling properly. Check the breaker panel for anything tripped, and if you have an outdoor unit, make sure nothing is blocking it. If all of that checks out and the system still is not working, a licensed contractor will need to diagnose it further.
