Eleven months of work, most years
In Peachtree Corners your system only gets a break for about a month. Heat runs November through April, and the AC picks up right after for May through September. Winter nights average 34°F, cold enough that the furnace cycles on and off most of the night. Summer afternoons hit 87°F, and the AC runs long stretches to keep up. That kind of steady demand wears on the parts that start the system up, the igniter on a gas furnace, the capacitor on the AC.
Storms add to it. Gwinnett County has seen 143 damaging wind events and 5 winter storms over the past ten years, and in 2024, close to a third of Georgia households lost power for at least a day. A hard outage can trip a furnace's control board or leave a heat pump needing a manual reset. When the power comes back, most systems restart on their own, but if something inside was already worn, that's when it shows.

A new furnace and air conditioner would cut about $180 a year off heating and cooling for a typical Gwinnett County home.
Estimates for a typical Gwinnett 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.
Georgia's Construction Industry Licensing Board tests contractors before they can hold this license, and it keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that covers a new install covers a repair call to your house.
For a heating and cooling repair, that license is what stands behind the work. Georgia's board is the one with the record of who is licensed to do this kind of work in your home.

- Why is my heat not working?
- The first thing to check is the thermostat, set it to heat and a few degrees above room temperature and see if the system responds. If nothing kicks on, check the breaker and any switch near the furnace itself, since a tripped breaker or a flipped switch will stop it cold. Gas furnaces have an igniter that wears out over time, and when it fails the blower runs but no heat comes out. With winter lows here averaging 34°F, a furnace that won't fire is worth getting 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, check the air filter first, a clogged one chokes off airflow and can ice up the coil behind it. Next check the outdoor unit and make sure nothing is blocking it, leaves, grass clippings, or anything stacked against it will cut its ability to move heat outside. If the filter is clean and the outdoor unit is clear, the system may be low on refrigerant or have a failing part, and that calls for a contractor with gauges to find out what's actually wrong.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it's set to the right mode, the batteries are good, and the temperature you want is actually different from the current room temperature. Check the breaker box for anything tripped and check that the filter isn't clogged, both are common causes that have nothing to do with the equipment itself. If the outdoor unit looks buried in leaves or debris, clearing it can help too. If you've checked all that and the system still isn't heating or cooling right, a licensed contractor can diagnose what's actually failing.
