Cabarrus County runs its systems almost year round
Your system works most of the year here. Heat from October through April, cooling from May through September, only a few weeks of rest between them.
Winter nights average 32°F, right at the freezing line, so the furnace cycles on and off most of the night to hold the temperature. Summer afternoons average 88°F, and the AC runs long stretches to keep up. 55.9% of homes here heat with electricity, so that strain shows up on a heat pump or electric furnace instead of a gas line. This area has also seen 60 damaging wind events and 7 winter storms over the past ten years, and in 2024 a quarter of North Carolina households lost power for at least a day. When the power drops and comes back, your system has to restart cold, and that is when a weak part finally gives out.

North Carolina requires HVAC contractors to hold a state license.
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tests HVAC contractors before they can hold a license, and it keeps a record of who passed. That license belongs to the contractor, not to any one job, so the same license that qualifies them to install a system is what qualifies them to repair yours.
For a repair job, that license is what stands behind the work. Whoever comes out to look at your furnace or your air conditioner should be able to point to that license, because in North Carolina it is the state, not the county or the city, that decided they were qualified to do this work.

- Why is my heat not working?
- Most of the time it comes down to one of a few things. If it is a gas furnace, the igniter or the flame sensor can fail, and the furnace will run its fan without ever lighting. If it is a heat pump, it may be stuck in defrost or struggling once temperatures drop toward that 32°F range you get on winter nights here. A dirty filter can also choke off airflow until the system shuts itself down to protect the heat exchanger. Check the thermostat setting and batteries first, since those get overlooked more than people expect.
- Why is my system running but not cooling the house?
- The system is running but the air coming out is not cold, which usually points to one of two things. A dirty or clogged filter cuts off airflow across the coil until it can freeze up, and once that happens the house stops cooling even though the fan keeps blowing. Low refrigerant from a leak is the other common cause, and that will need a contractor with gauges to find and fix. On a 88°F afternoon here, a system fighting either of these problems will run long and still lose ground.
- 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 filter and replace it if it is gray or clogged, since a blocked filter can stop a system cold on either side of the year. Look at the breaker panel too, since a tripped breaker will shut the whole system down without any other warning. If the outdoor unit will not start at all, check that nothing is blocking it, and if you still cannot find the problem after these, a licensed contractor can diagnose it from there.
