Eleven months of work a year in Dunn
Your system in Dunn only gets a short break. Heat runs October through March, then cooling takes over from May through September. That is eleven months where either the furnace or the air conditioner has to work, with barely a month of rest in between.
Winter nights averaging 33°F mean the burner or heat strip cycles on and off for hours at a stretch, and most homes here heat with electricity, so that load falls on the heat pump or furnace directly. Summer afternoons averaging 89°F push the air conditioner just as hard from the other direction. Add in the storms, Harnett County has seen 76 damaging wind events over the past ten years, and a quarter of North Carolina households lost power for at least a day in 2024. When power drops and comes back, most systems restart on their own, but a system already worn down by all that cycling is the one that fails to.

North Carolina requires HVAC contractors to hold a state license.
The license comes from the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. The board holds the record of who is licensed, and that record follows the contractor, not the job in front of them. A license here means the state tested this contractor and has them on file.
For a repair on your heating and cooling system, that license is what stands behind the work. North Carolina ties its licensing to the contractor rather than to each job that contractor does. If the repair touches the gas line, that connection is the part that has to be right, since a bad one is what makes the job dangerous.

- Why is my heat not working?
- Most often it's the thermostat, the igniter, or the power to the furnace. If the display is dark, check the breaker and the switch that looks like a light switch near the furnace. If the furnace runs but no heat comes out, the igniter may have failed, which is common as parts age and won't fix itself. With most homes here relying on electric heat and winter lows averaging 33°F, a furnace that won't start is worth getting looked at the same day.
- Why is my system running but not cooling the house?
- The fan may be moving air, but the compressor outside isn't doing its job. Check the outdoor unit first. If it's silent while the indoor fan runs, that points to the compressor, the capacitor, or a tripped breaker. A dirty air filter can also choke airflow enough that the house never cools, so check that before anything else. With summer afternoons here averaging 89°F, a system that's only moving warm air needs a contractor to find out which part quit.
- What can I check before calling for HVAC repair?
- Start with the filter. A clogged one restricts airflow and can make a working system seem broken. Next, check the thermostat has power and is set below room temperature for cooling or above it for heat. Then look at the breaker panel for anything tripped, especially after a storm, since Dunn has logged 76 damaging wind events over the past ten years. If those check out and the system still won't run right, a licensed contractor can diagnose what's actually wrong.
