Clayton asks a lot of your system, in both directions
Your furnace runs October through April here, and your air conditioner takes over for May through September. That is every month of the year with one system or the other working. Winter nights averaging 33°F mean the burner cycles on and off for hours at a stretch, and summer afternoons near 89°F keep the compressor under load most of the day.
Most homes in Clayton heat with electricity, so a heat pump or electric furnace is doing that work, and a hard freeze or a breaker issue can leave you with no backup. Storms are part of the picture too. Johnston County has seen 164 damaging wind events and 7 winter storms over the past ten years, and a quarter of North Carolina households lost power for at least a day in 2024. When the power comes back, most systems restart on their own, but if yours does not, that is worth a call.

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. It belongs to the contractor, not to any single job, so the same license covers this repair and every other job that contractor takes on.
For a heating and cooling repair, that license is what stands behind the person working on your system. It does not get issued fresh for this job. It is the same credential the state attached to this contractor before your repair ever came up.

- Why is my heat not working?
- Start with the thermostat. Check that it is set to heat, not cool, and that the temperature you want is above the room temperature. If the thermostat looks right, check the breaker for the furnace or air handler, since a tripped breaker will shut the whole system down. Gas furnaces need power too, so a breaker trip can stop a gas furnace as much as an electric one. If the breaker is fine and you still have no heat, the igniter or the flame sensor may have failed, and that needs a contractor to look at it. With winter nights averaging 33°F here, a furnace that will not heat is worth calling in soon rather than waiting it out.
- Why is my system running but not cooling the house?
- The most common reason is a dirty air filter blocking airflow. When the filter is clogged, the coil inside can freeze up, and a frozen coil will run and run without ever cooling the air. Check the filter first and replace it if it looks gray or packed with dust. If the filter is clean and the air coming from the vents is warm, the system could be low on refrigerant or have a failing compressor, and that is a job for a contractor to diagnose. With summer afternoons here reaching 89°F, a system that runs without cooling can let a house heat up fast.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it is set to the mode you want, heat or cool, and that the battery is not dead if it uses one. Check the breaker for the furnace or air handler and reset it if it has tripped. Then check the air filter. A filter clogged with dust chokes off airflow and can cause problems on both the heating and cooling side. If all of that looks normal and the system still is not working right, a contractor can diagnose what is going on inside the unit itself.
