Nine months of heat, and nights near zero
Velva needs heat from September through May and cooling in July and August, so a mini-split here runs almost all year. Winter nights average 3°F, which puts real load on a heat pump's low-temperature performance for most of the season it works.
Any mini-split installed new has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. With McHenry County summers only reaching an average 79°F in the afternoon, cooling asks little of the system. The winter side is where the unit earns its keep.

North Dakota requires HVAC contractors to hold a state license.
The license belongs to the contractor, not to any single job, so the same license covers this installation and anything else that contractor takes on in the state. Work under $4,000 falls outside the requirement, but installing a mini-split runs well past that mark, so the contractor doing this job needs to hold that license.
Most cities and counties in North Dakota require a permit for installing a system like this, along with an inspection once the work is finished. That permit and inspection are separate from the license itself, and they are what checks the installation, the wiring and the connections, after the work is done.

- Is a mini split worth it?
- For most homes here, yes, because a mini split is doing real work eleven months out of the year between the heat and the cooling. Winter nights average 3°F, so the unit needs to be a cold-climate model rated to keep producing heat down at those temperatures, not just any heat pump. Summers only average 79°F in the afternoon, so the cooling load is light and a mini split handles it easily. A contractor can size the right unit once they see the house and tell you what it costs.
- How many rooms can a mini split cover?
- One outdoor unit can run several indoor heads, and how many depends on the model and its capacity. Each head is matched to the room it heats and cools, so the more rooms you want covered, the larger the outdoor unit needs to be. Open floor plans can sometimes get by with fewer heads than the room count suggests. A contractor will walk the house and tell you how many heads it actually needs.
- Can a mini split heat a whole house?
- It can, if it is sized and placed for that from the start. With nine months of the year needing heat here, and winter lows averaging 3°F, the system has to be a cold-climate mini split built to keep its heating output at those temperatures. Every room that needs heat has to get its own indoor head, or be open enough to a room that does. A contractor can look at the layout and tell you whether whole-house coverage is realistic for that house.
