A heat pump here works most of the year
A heat pump in Onslow County heats the house from November through March and cools it from May through September, ten months of the year in one mode or the other. Winter nights average 35°F, mild enough that a heat pump can carry the load without much strain. Summer afternoons average 88°F, and that is what it is pulling heat against on the five months it runs for cooling.
Most homes here heat with electricity, so on those winter nights the heat pump is doing that job alone. Any new split-system heat pump has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum for units built since 2023. Storms are part of living here too. Onslow County has seen 68 damaging wind events over the past ten years, and a quarter of North Carolina households went at least a day without power in 2024. A heat pump comes back on by itself once power is restored.

North Carolina requires HVAC contractors to hold a state license.
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tests contractors before issuing a license and keeps a record of who holds one. That license belongs to the contractor, not to any single job, so the same license that would cover a furnace repair covers this heat pump installation.
In most cities and counties in Onslow, a heat pump installation needs a permit from the local building office, with an inspection once the work is finished. That inspection checks the installation itself, separate from the license the contractor already holds.

- Is a heat pump better than a furnace?
- A heat pump does what a furnace and an air conditioner do together, so it heats in winter and cools in summer from one system. A furnace only heats. Jacksonville needs both, heat from November through March and cooling from May through September, so one system that does both has less equipment to install and maintain than two separate units. Whether it is the right choice for a given house still depends on the home's ductwork and current setup, which a contractor can look at directly.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only moves heat out of the house. A heat pump can do that same job in summer, then run in reverse and move heat into the house in winter. The parts inside are similar, but the heat pump has a reversing valve that lets it switch directions, which is what lets it heat as well as cool.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from the outside air even when it's cold, though it has less heat to work with as the temperature drops. Winter nights in Jacksonville average 35°F, which is well within the range a heat pump is built to handle. Federal minimums now require new heat pumps to meet 7.5 HSPF2 for heating, a rating that reflects performance across a full winter, not just on mild days.
