Dunn asks a lot of a new system, most of the year
Your heating or cooling is running eleven months out of the year in Dunn. Heat is needed October through March, six months, when winter nights average 33°F. Cooling picks up May through September, five months, with summer afternoons averaging 89°F.
Most homes here heat with electricity, so the system you install is doing the bulk of the work in both seasons. This area has also seen 76 damaging wind events and 5 winter storms over the past ten years, and in 2024, a quarter of North Carolina households lost power for at least 24 hours. A new system should come back on its own once power is restored, without anyone having to reset it.

North Carolina requires HVAC contractors to hold a state license.
The license is issued to the contractor, not to this particular job. The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tested that contractor before handing it out, and it keeps a record of who holds one. That is what backs the person coming to install your system, not a stamp on this specific installation.
For the install itself, the protection here comes from the local building office. Putting in a new furnace, air conditioner or heat pump in most cities and counties in North Carolina needs a permit, and the finished work gets inspected before anyone calls it done. That inspection is what catches a bad gas connection or wiring that was not done right, separate from whatever the license already vouches for in the contractor who did it.

- When should I replace my HVAC system?
- Replace it when it can no longer keep the house comfortable or when repairs keep coming back. Older equipment tends to fail at the worst time, so if a contractor has been out more than once for the same problem, that is a sign the unit is done. Rising energy bills with no other explanation and uneven temperatures from room to room point the same way. Homes here need heat or cooling 11 months of the year, so a system that is struggling does not get much of a break to recover.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together is usually the better move. A furnace and air conditioner installed years apart are often mismatched, and once one fails the other tends to follow soon after. Doing both at once also means the whole system is sized and installed to work together from the start, rather than pairing new equipment with a unit that is already wearing out. If one unit is clearly newer than the other, a contractor can tell you whether it makes sense to wait.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sizes and sets the new furnace and air conditioner or heat pump, and connects it to the existing ductwork, gas line or electrical circuits as needed. They check refrigerant lines, venting, and the thermostat, then run the system through a full heating and cooling cycle before calling the job done. Replacing this kind of equipment needs a permit from the local building office and an inspection once the work is finished. North Carolina also requires the contractor doing the work to hold a state HVAC license.
