Ten months a year of heating or cooling in Kingwood
Winter nights here average 22°F from December through February, and a mini-split heat pump has to keep pulling heat out of that cold air the whole stretch from October through May. That's 8 months of heating. Summer only asks for two months of cooling, when afternoons average 79°F, so the system you install spends most of its life in heat mode, not cooling mode.
A new mini-split installed today has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the federal minimum for split-system heat pumps since January 2023. Preston County also sees real storm weather, 36 winter storms and 108 damaging wind events over the past ten years, and outages that follow. Most mini-splits come back on by themselves once power returns, which matters here.

West Virginia requires HVAC contractors to hold a state license.
That license comes from the Commissioner of Labor, and it belongs to the contractor, not to any single job. It covers the person or business taking on the work, not the mini-split itself once it's on the wall.
In most cities and counties here, putting in a mini-split means pulling a permit from the local building office, with an inspection once the work is done. That inspection is what checks the finished job. The license and the inspection are two different things, one for the contractor, one for the install.

- Is a mini split worth it?
- For most homes it comes down to what rooms need heat or cooling and whether ducts reach them well. Kingwood needs heat from October through May and cooling in July and August, so a system that handles both jobs well earns its keep most of the year. A mini split runs on a heat pump, so it heats and cools from the same unit, and it can serve a room that never had ductwork at all. Whether it makes sense for your house depends on the layout, and a contractor can walk it with you and tell you what fits.
- How many rooms can a mini split cover?
- A single outdoor unit can run more than one indoor head, and multi-zone systems commonly support two to eight, depending on the equipment. Each indoor head heats and cools the room it's mounted in, so the number you need matches the number of rooms you want covered. A contractor sizes the outdoor unit to the combined load of every indoor head you're planning to add.
- Can a mini split heat a whole house?
- It can, if enough indoor heads are placed to reach every room, but a single head only heats the space it's in. A multi-zone system with a head in each main room can cover a whole house the same way a central furnace would, just delivered room by room instead of through ducts. Kingwood winters average 22°F, so the system has to be sized for that low, not just for a mild day. A contractor can look at the house and tell you how many heads it takes to cover it.
