Twelve months of work for one unit
Your heat pump runs almost the whole year in Holly Springs. Winter nights average 33°F from December through February, mild enough that it can keep pulling heat from the outside air without much strain. Summer afternoons average 90°F, and the same unit switches over to cooling for May through September. Between the two seasons, it is working 12 months a year, with no real break.
A new split-system heat pump has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating if it was built on or after January 1, 2023. With 43.5% of homes here heating with electricity, the heat pump is doing that work directly, not backing up a furnace.

Mississippi requires HVAC contractors to hold a state license.
The license is issued to the contractor's business, not to this specific job. That means Mississippi tested and recorded the contractor before the license was granted, and the state keeps that record on file. It does not mean a state employee will show up to check the heat pump once it is in.
That check comes from the local building office instead. In most cities and counties, installing a heat pump needs a permit before the work starts and an inspection once it is done, and that inspection is what confirms this specific installation, not just the contractor behind it.

- Is a heat pump better than a furnace?
- A heat pump does both heating and cooling, where a furnace only heats. That matters here since homes need heat from October through April and cooling from May through September, so a heat pump covers all twelve months with one system. A furnace still burns gas or uses electric resistance to make heat, and it needs a separate air conditioner alongside it. Which one fits your house better is worth going over with a contractor, since duct layout and how your home is set up play into it too.
- What's the difference between a heat pump and an air conditioner?
- An air conditioner only removes heat from your home and sends it outside. A heat pump does that same job in summer, but it can also run in reverse and pull heat from the outside air into your home in winter. Mechanically they share the same basic parts, the compressor, the coils, the refrigerant. The difference is the reversing valve that lets a heat pump switch direction.
- Does a heat pump work in cold weather?
- Yes, a heat pump pulls heat from outside air even when it's cold, though it works harder as the temperature drops. Winter nights here average 33°F, which is well within the range a heat pump handles. Heat pumps installed now have to meet a federal minimum of 7.5 HSPF2 for heating, so they're built to perform through a full winter. Some models add backup electric heat strips for the coldest stretches, which a contractor can size for your house.
