A mini-split in Oakes has to handle nine months of heat
Homes here need heat from September through May, nine months of the year, with winter nights averaging 6°F from December through February. Summer asks much less of it, just three months, with afternoons averaging 79°F. A mini-split installed here spends most of its life on the heat pump side, not the cooling side, so it has to be sized for that cold.
Any unit manufactured now has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, the same federal minimum as any other split-system heat pump. Close to half of homes in the state heat with electricity, and winter storms are common here, so a mini-split that keeps up on the coldest nights, and comes back on if the power drops out, matters.

North Dakota requires HVAC contractors to hold a state license.
The license is held by the contractor, not tied to this job. It means the state tested that contractor and keeps a record of them. In North Dakota, work under $4,000 does not need a licensed contractor. A mini-split installation runs well past that, so the contractor doing this job should hold the state license.
The license covers who the contractor is, not what happens on site. That part falls to the local building office. Most cities and counties require a permit for a mini-split installation and an inspection once the work is done, and that inspection is what checks the wiring and refrigerant connections rather than the license itself.

- Is a mini split worth it?
- It depends on what you're heating or cooling and what's there now. A mini split makes sense for a room addition, a garage, or a home that relies on electric baseboard or window units, since it heats and cools that space without ductwork. Here, with heat needed from September through May and winter nights averaging 6°F, the outdoor unit has to be rated for cold climates to keep up on the coldest nights. A contractor can look at the space and tell you whether it covers your needs on its own or works better alongside your existing system.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Single-zone systems cover one room or open area. Multi-zone systems tie several indoor heads, often in different rooms, back to one outdoor unit, with each head controlled on its own. How many rooms a given system can handle comes down to the size of the outdoor unit and the total load of the rooms you want it to cover, which is something a contractor sizes for your house.
- Can a mini split heat a whole house?
- It can, but it takes the right setup. A multi-zone system with enough indoor heads placed through the house can heat every room, and cold-climate models are built to keep working even when it's well below freezing outside. With winter nights here averaging 6°F, the system has to be sized and rated for that kind of cold, not just for milder weather. A contractor can work out how many zones your house needs and whether the outdoor unit can keep pace on the coldest nights.
