Dunn asks a heat pump to work almost all year
Homes in Dunn need heat or cooling 11 months a year. Winter nights average 33°F from December through February, and summer afternoons average 89°F. A heat pump here spends October through March pulling heat into the house and May through September pulling it out, with barely a month of rest between.
Most homes in the area heat with electricity, so the heat pump carries that load directly. Any new split system installed now has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. Harnett County has also seen its share of winter storms and damaging wind over the past ten years, and a quarter of North Carolina households went at least 24 hours without power in 2024. A heat pump does not run without power, and that is worth planning around.

North Carolina requires HVAC contractors to hold a state license.
North Carolina's Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tests and licenses the contractor, not the job. The license belongs to the business, so it stays in place from one installation to the next rather than being issued fresh each time.
For this heat pump installation, that license is what stands behind the work. In most cities and counties, a heat pump replacement also needs a permit from the local building office, with an inspection once the work is done. That inspection checks the installation itself, separate from the contractor's license.

- Is a heat pump better than a furnace?
- It depends on what you're comparing it to and what you want it to do. A heat pump both heats and cools, so it replaces a furnace and an air conditioner with one system. A furnace only heats, and it burns gas or runs on electric resistance, while a heat pump moves heat instead of generating it, which is why it costs less to run in most cases. Around Dunn, winter lows average 33°F, well within the range a modern heat pump handles without help from a backup heat source.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools your home. A heat pump does the same job in summer, but it can also run in reverse to heat your home in winter. Mechanically they're close cousins, both use a compressor and refrigerant to move heat from one place to another, but the heat pump has a reversing valve that lets it pull heat from outside air and bring it indoors.
- Does a heat pump work in cold weather?
- Yes, a heat pump keeps working in cold weather, though it pulls less heat from the outside air as the temperature drops. In Dunn, winter nights average 33°F from December through February, which is mild enough that a properly sized heat pump covers the heating load on its own most of the season. Federal rules now require new split-system heat pumps to hit at least 7.5 HSPF2 for heating, so newer units are built to perform through a full winter, not just the easy months.
