Iredell County runs your system almost year round
Heat from October through April, cooling from May through September. That leaves almost no month where your furnace and your AC both sit idle. Winter nights averaging 30°F mean the heat exchanger cycles on and off for hours at a stretch, and summer afternoons near 86°F keep the compressor working through the hottest part of the day.
Most homes here heat with electricity, so a breaker problem or a bad heat strip shows up as a cold house, not just a quiet furnace. Iredell County has seen 9 winter storms and 105 damaging wind events over the past ten years, and a quarter of North Carolina households lost power for a full day or more in 2024. When the power drops and comes back, most systems restart on their own. If yours does not, that points to a problem worth checking before the next outage.

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 you, so it does not get reissued each time someone calls for a repair.
That license is what stands behind the work on your heating and cooling system, whoever you hire. It belongs to the person or company doing the job, not to the particular repair, but it is the same license either way, tested and held under the Board's name.

- Why is my heat not working?
- Most no-heat calls come down to power, gas, or airflow. Check that the thermostat is set to heat and the temperature is above room temperature, and check the breaker for the furnace or air handler. If you smell gas, leave the house and call the gas company, not a contractor. With winter nights here averaging 30°F, a furnace that won't fire is worth getting looked at the same day rather than waiting it out.
- Why is my system running but not cooling the house?
- If air is moving but it is not cold, the most common causes are a dirty filter, a frozen coil, or low refrigerant. A clogged filter starves the system of airflow, and once ice builds on the coil the whole system loses its ability to cool. Turn the system off and let any ice melt before a contractor looks at it, since running it iced up can damage the compressor.
- What can I check before calling for HVAC repair?
- Start with the thermostat. Make sure it is set correctly, has fresh batteries if it takes them, and is actually calling for heat or cooling. Check the breaker panel for a tripped breaker, and check the filter, since a filter clogged with dust can shut a system down on its own. If those all check out and the system still is not working, a licensed contractor will need to look at it, since North Carolina requires HVAC contractors to hold a state license for this kind of repair.
