Guilford County runs its heating and cooling nearly all year
Your system works October through April to keep the house warm, then May through September to keep it cool. That is 12 months of use, with barely a break between seasons.
Winter nights average 31°F here, so the furnace or heat pump cycles on and off for hours at a time. More than half of homes in the area heat with electricity, which means that system carries the load night after night. Summer afternoons average 87°F, and the AC answers back just as often. All that cycling wears on the parts that start the system up. That is usually where trouble shows first. A system that won't kick on, or one that runs but never catches up to the thermostat.
Guilford County has seen 12 winter storms and 166 damaging wind events over the past ten years. A quarter of North Carolina households lost power for at least 24 hours in 2024. Most systems restart on their own once power comes back. A storm that knocks branches into an outdoor unit, or one that cuts power for a stretch of freezing nights, can leave a system unable to recover without a repair.

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 covers the contractor, not the job in front of them, so the same license stands behind every repair that contractor takes on, not just this one.
For a repair on your heating and cooling system in Guilford County, that state license is what stands behind the person doing the work. Gas is often part of a heating repair, and the connection is the part that has to be right, since a bad one is what turns a repair into a hazard. The state's licensing rule is what stands behind that in North Carolina.

- Why is my heat not working?
- Most often it's the thermostat, the igniter, or the power to the furnace. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker for the furnace. Winter nights in Greensboro average 31°F, so a furnace that won't light is worth calling in fast. If the thermostat and breaker check out, the igniter or flame sensor is a common next place for the problem to be, and that's a repair for a licensed contractor.
- Why is my system running but not cooling the house?
- The blower may be moving air that was never cooled. Start with the air filter. A filter clogged with dust chokes off airflow across the coil, and the coil can ice over when that happens. If the filter looks clean and the vents are still blowing warm, the system is likely low on refrigerant or has a coil problem, and that calls for a licensed contractor to diagnose.
- What can I check before calling for HVAC repair?
- Check the thermostat first. Make sure it's set to heat or cool as needed and the batteries aren't dead. Check the air filter next and replace it if it's gray with dust, since a blocked filter can cause both weak heat and weak cooling. Then check the breaker panel for a tripped breaker, especially after a storm. Greensboro sees its share of damaging wind, and a tripped breaker after one is common. If everything there looks right and the system still isn't working, a licensed contractor can diagnose what's left.
