What Clayton asks of a heat pump
Clayton needs heat or cooling every month of the year. Winter nights average 33°F from December through February, mild enough that a heat pump can carry the load without much help from backup heat. Summer afternoons average 89°F, and cooling runs from May through September, five months straight.
Most homes here heat with electricity, so the heat pump carries the load October through April too, not just in summer. Any split-system unit installed new has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum since 2023. Johnston County has seen 7 winter storms and 164 damaging wind events over the past ten years, and a quarter of North Carolina households went at least 24 hours without power in 2024. Worth asking what happens to your heat when the power does.

North Carolina requires HVAC contractors to hold a state license.
The state exam covers the trade generally, and the license is tied to the contractor rather than to any single job. That means the same license that qualifies someone to work in Johnston County qualifies them for any HVAC job anywhere in North Carolina, this installation included.
On top of that license, a heat pump installation in most cities and counties needs a permit from the local building office, with an inspection once the work is done. That inspection is separate from licensing. It is the local check that the unit was installed correctly, not a record of who did the work.

- Is a heat pump better than a furnace?
- It depends on what you're comparing it to. A heat pump moves heat instead of burning fuel to create it, so it can deliver more energy than it uses, and it cools your home in summer too, which a furnace can't do. Where a heat pump falls short is on the coldest nights, when it has to work harder to pull heat from outside air. Clayton winters average 33°F, which a heat pump handles fine, so for most homes here it covers both jobs a furnace and an air conditioner would split between them.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only cools. A heat pump does the same thing an air conditioner does in summer, moving heat out of your home, but it can also run in reverse and move heat into your home in winter. Mechanically they share most of the same parts, a compressor, a coil outside, a coil inside. The difference is the reversing valve that lets a heat pump switch directions, which is why one system can replace both your furnace and your air conditioner.
- Does a heat pump work in cold weather?
- Yes. A heat pump pulls heat from outside air even when that air is cold, because there's still heat in air well below freezing. It works harder as the temperature drops, and its output falls off some on the coldest nights. Winter nights in Clayton average 33°F, which is well within the range a heat pump handles without trouble. Homes here need heat from October through April, so the system is sized and installed with that full stretch in mind, not just the mild days.
