Kanawha County asks a mini-split to run most of the year
Winter nights here average 27°F from December through February, and summer afternoons run about 84°F. Homes in this county need heat from October through April and cooling from June through September, eleven months of the year with only one month asked of neither. A mini-split installed here spends most of the year working, not sitting idle.
Any new mini-split has to meet the federal minimum for a split-system heat pump, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. That is the floor, not a ductless-specific rule. Storms are part of what this equipment lives through here too. The county has seen 16 winter storms and 259 damaging wind events over the past ten years, and over a third of West Virginia households went at least 24 hours without power in 2024.

West Virginia requires HVAC contractors to hold a state license.
That license comes from the Commissioner of Labor. The state tested the contractor and keeps a record of them before letting them hold it. It covers the contractor as a business, not the mini-split going into your home. Every job still has to be done right, but the license is what says the person doing it met the state's standard in the first place.
For the installation itself, the license is not what catches a mistake on your wall. In most cities and counties, putting in a mini-split needs a permit from the local building office and an inspection once the work is done. That inspection is what checks the line set and the mounting, not the license.

- Is a mini split worth it?
- For a lot of homes, yes. A mini split heats and cools without ducts, so it works well for additions, converted spaces, or a house that needs heat one part of the year and cooling the other. Homes here need heat from October through April and cooling from June through September, so a system built to do both jobs earns its keep. A contractor can look at the space and tell you if it fits better than the alternatives.
- How many rooms can a mini split cover?
- A single indoor unit is built for one room or one open area. If you need to cover more rooms, a multi-zone system runs several indoor units off one outdoor unit, with each zone controlled on its own. How many zones a house can support depends on the outdoor unit's capacity and the layout, so a contractor sizing the job will work that out room by room.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for that. A multi-zone mini split with enough indoor units, one for each room or area that needs heat, can carry a whole house the way a central system does. What that takes depends on the size of the house and how it's laid out, so a contractor would need to look at the specific home to size it right.
