What Morgantown winters ask of a mini-split
Your mini-split has to hold up on nights that average 24°F, and it has to work most of the year. Heat runs October through May here, eight months, then cooling picks up June through August. Only one month sits outside either season. A unit sized and installed for that stretch will be running its compressor on the coldest nights of the year, not just cooling in summer.
Any new ductless heat pump built since January 1, 2023 has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, so that floor is already set before you choose a model. Beyond that, what matters here is whether the unit was sized for a 24°F low, not a mild one, since that's the temperature it will lean on most winter nights.

West Virginia requires HVAC contractors to hold a state license.
West Virginia's Commissioner of Labor issues that license after testing the contractor, and keeps a record of who holds one. The license belongs to the contractor, not to any single job, so the same license that qualifies them for other HVAC work is what qualifies them for yours.
For a mini-split install, that license is what stands behind the person doing the work. In most cities and counties in West Virginia, this kind of installation also needs a permit from the local building office, with an inspection once the work is done.

- Is a mini split worth it?
- For the right house, yes. A mini split heats and cools without ductwork, so it works well in additions, converted attics, garages, or any room that never got comfortable with what you already have. Winters here average 24°F, and newer heat pump models keep working well below that. If your home already has good ducts and a working furnace or central system, a mini split is more often used to fix one room than to replace what's already there.
- How many rooms can a mini split cover?
- A single-zone system heats and cools one room or open area. A multi-zone system connects one outdoor unit to several indoor heads, and most residential models support somewhere between two and eight zones. Each indoor head is sized and placed for the room it serves, so a contractor will look at the layout of the house before saying how many zones it needs.
- Can a mini split heat a whole house?
- It can, if it's sized and laid out for that. A multi-zone mini split puts an indoor head in each room or living area, all run from one outdoor unit, and this works as the only heat source in plenty of homes. Homes here need heat from October through May, so the system has to be sized for nights that drop to 24°F, not just for mild weather. Getting whole-house coverage right depends on the square footage, the layout, and how the house holds heat, so a contractor needs to walk through it before sizing the system.
