A system that works almost the whole year
Mecklenburg County only gets a break from heating or cooling a few weeks a year. Furnaces run October through April, seven months, with winter nights averaging 32°F. Air conditioners run May through September, five months, against summer afternoons that average 88°F. A new system has to handle both jobs well, not just one.
More than half of homes here heat with electricity, so the furnace or heat pump you choose is doing real work all winter. Storms are part of the picture too. The county has seen 122 damaging wind events and 6 winter storms over the past ten years, and a quarter of North Carolina households lost power for a full day or more in 2024. Whatever you install, know how it comes back on once the power does.

North Carolina requires HVAC contractors to hold a state license.
North Carolina licenses HVAC contractors through the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors. That license belongs to the contractor, not the job, so the one who installs your furnace and air conditioner is covered by the same license for both.
For this job, the license tells you the contractor is the one the state holds accountable. The installation itself gets checked a different way. In most cities and counties in Mecklenburg, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work is inspected once it's done. That inspection is what catches a bad gas line or a system that was not connected right.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when the system is old, or when it can't keep the house comfortable anymore. An aging furnace or air conditioner is a candidate even if it still runs, because the parts inside wear out over time and failures start costing more than the unit is worth. Rising energy bills without any other explanation are another sign, since a struggling system uses more power to do the same job. If you're weighing one more repair against replacing the whole system, a contractor can look at the age and condition of what you have and tell you which makes sense.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, replacing them together is usually the better choice. A furnace and air conditioner installed at the same time wear out around the same time, so if one is failing the other is probably not far behind. They also share the blower and ductwork, so a new system matched to both sides tends to run better than pairing a new unit with an old one. If your equipment is at different ages or one was already replaced more recently, a contractor can tell you whether it makes sense to do both now or wait.
- What happens during an HVAC installation?
- The old furnace, air conditioner, or heat pump comes out, and the new equipment goes in and gets connected to the ducts, electrical, refrigerant lines, and venting it needs. The contractor sizes the new equipment to the house rather than just matching what was there before, since a system that's too big or too small won't run efficiently. Once it's in, they test it, check refrigerant levels and airflow, and make sure it's working the way it should. In most cities and counties here, this job needs a permit from the local building office and an inspection when the work is done.
