New Town asks a mini-split to run almost all year
Nights here average 4°F in December through January and February, and homes need heat from September through June. That is ten months of heating, plus two more of cooling when summer afternoons reach 79°F. A mini-split installed here is working most months it will ever see.
Any new mini-split with a manufacture date of 2023 or later has to meet 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, since the federal minimum treats it as a split system like any other heat pump. Given how often the outages run here, with 7% of North Dakota households losing power for a day or more in 2024 and 21 winter storms recorded in the last ten years, it is worth asking an installer how the unit you choose handles a cold restart after the power drops.

North Dakota requires HVAC contractors to hold a state license.
North Dakota's license is held by the contractor, not issued per job, so it records the business doing the work rather than this specific installation. Work under $4,000 falls outside that requirement, and depending on the equipment and scope, a mini-split installation can land on either side of that line.
Most cities and counties require a permit for this kind of installation, with an inspection once the work is finished. That inspection is separate from the state license, and it is what catches a bad connection or an installation that was not done to code.

- Is a mini split worth it?
- For most homes here, yes, because a mini split heats and cools with a single system that runs on electricity, and homes here need heat or cooling all 12 months of the year. It also gives you a source of heat that does not depend on ductwork, which matters given how often this area sees winter storms and damaging wind. A contractor can look at your home and tell you whether one unit or several zones make sense for you.
- How many rooms can a mini split cover?
- A single outdoor unit can run more than one indoor head, so it can cover more than one room. Each indoor head is sized to the room it serves, so a bigger house usually means more heads rather than one oversized unit. A contractor will size the system to your rooms, not the other way around.
- Can a mini split heat a whole house?
- Yes, if it is sized and placed for the whole house rather than a single room. That means enough indoor heads, in the right rooms, matched to an outdoor unit that can handle winter nights that average 4 degrees here. This is a design job, so a contractor needs to look at the layout of your house before saying what setup will carry the whole place through winter.
