Twelve months of work, most homes on gas
Your system doesn't get a season off in Canton. Heat runs October through April, then cooling takes over for May through September. That's every month of the year with something running, and most homes here do the heating side with gas.
Winter nights averaging 33°F mean the burner cycles on and off for hours at a stretch, and each start puts wear on the igniter and the flame sensor. Come summer, afternoons near 87°F push the compressor hard for five straight months. Add in the storms, Cherokee County has seen 149 damaging wind events and 6 winter storms over the last ten years, and the power outages that come with them. Nearly a third of Georgia households lost power for a day or more in 2024, and when the power comes back, a furnace or AC that won't restart on its own is often the reason someone's calling for repair.

NOAA nClimDiv, 1991–2020 normals
A new furnace and air conditioner would cut about $180 a year off heating and cooling for a typical Cherokee County home.
Estimates for a typical Cherokee 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 issues that license, and it covers the contractor, not the individual job. It stays attached to them across every job they take on, rather than being reissued for each repair call.
For a repair like this, the license is what stands behind the person working on your system. Georgia's board is what backs the contractor here, tied to who they are as a business rather than to the paperwork for this one visit.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat and the temperature is set above the room temperature, and check the batteries if it uses them. If the thermostat looks right, check the breaker box for a tripped breaker, since a furnace that lost power will not ignite. Gas furnaces also need power for the igniter and control board, so a furnace with no power will not light even though gas is available. If power and the thermostat both check out and the furnace still will not run, it needs a contractor to look at it.
- 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 without enough airflow the coil can ice over and stop cooling the air that passes through it. Check that all the supply vents in the house are open, since closed vents add to the same airflow problem. If the filter is clean and the vents are open and the house still is not cooling, the system needs a contractor to check the refrigerant charge and the coil.
- What can I check before calling for HVAC repair?
- Check the thermostat settings and the batteries first, since a wrong setting or dead batteries can look like a bigger problem. Check the breaker box for a tripped breaker on the furnace or the outdoor unit. Check the air filter and replace it if it is dirty, since a clogged filter causes both heating and cooling problems. If the outdoor unit is covered in leaves or debris, clear the area around it so air can move through it. If everything checks out and the system still is not working right, a contractor will need to diagnose it further.
