Guilford County asks for heat and cooling both, most of the year
Winter nights here average 31°F from December through February, and the furnace or heat pump needs to run from October through April, seven months straight. Summer afternoons average 87°F, and cooling runs May through September. Put those together and a system here is working nearly every month, not just a few.
More than half the homes in this area heat with electricity, so a heat pump or electric furnace has to keep up on those 31°F nights without help from gas. And with 12 winter storms and 166 damaging wind events recorded here over the past ten years, the power going out is not rare. A quarter of North Carolina households lost power for at least 24 hours in 2024. A new system installed here should be sized for what the season actually demands, not just what fits the budget.

North Carolina requires HVAC contractors to hold a state license.
The license is held by the contractor, not issued job by job, so the board's exam and record follow the business across every install it does, including this one. That is what keeps a stranger accountable once the equipment is in your house.
For this kind of job, licensing is only part of it. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and an inspector checks the work once it is done. That inspection is what confirms the gas connections, wiring and refrigerant lines were done right, separate from anything the state license covers.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the system is old enough that the next breakdown is likely to cost more than replacing it does. Furnaces and air conditioners both get less reliable as they age, and if yours needs a repair and has some years on it, it's worth getting a replacement quote alongside the repair cost. Homes here need heat or cooling every month of the year, so a system that's struggling doesn't get an easy season to coast through. If your energy bills have climbed without an obvious reason, or one room never gets comfortable no matter what you do, those are signs too.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, replacing both at once usually makes sense. A furnace and air conditioner installed together are matched to work as a system, and pairing a new one with an old one can mean the new unit never runs at its best. It also means one installation instead of two, and one point where everything gets inspected and signed off. If your furnace and air conditioner were installed years apart, a contractor can look at both and tell you whether replacing just one now is reasonable or whether it's worth doing together.
- What happens during an HVAC installation?
- A contractor removes the old furnace or air conditioner and any parts that won't carry over, then sets the new equipment in place and connects it to the ductwork, refrigerant lines, gas line or electrical circuit it needs. They check the ducts for leaks or sizing problems while they're in there, since a new system connected to bad ductwork won't perform the way it should. Once it's running, they test it, check refrigerant levels or gas pressure, and confirm it's heating or cooling correctly. This work needs a permit from the local building office and an inspection when it's done, and it has to be done by a contractor licensed with the state board. That inspection is there to confirm the installation was done right, so don't skip it even if a contractor offers to.
