A mini-split in Hoonah works year round
There is no summer here to speak of. Afternoons average 63°F, so the mini-split's job most of the year is heat, not cooling. Winter nights average 27°F from December through February, and the unit needs to hold that ground for months, not just on the coldest week.
Most homes here still heat with fuel oil. A mini-split installed now has to be sized and set up to carry real winter load on its own, or to work alongside the oil system, not just take the edge off. Any new unit built since January 2023 has to meet 7.5 HSPF2 for heating and 14.3 SEER2 for cooling, but in a place that runs cold most of the year, how well it holds up on the coldest nights matters more than the cooling number ever will.

Alaska requires contractors to register with the state.
Alaska's registration puts the business on file with the state. Nobody tests the contractor's trade knowledge, and no license backs the work. It tells you the business exists on paper, not that the state checked its skill.
For a mini-split, the protection comes from elsewhere. In most cities and counties here, installing a mini-split needs a permit from the local building office, with an inspection once the work is done. That inspection is what checks the installation, not the state registration.

- Is a mini split worth it?
- Yes, especially here where homes need heat all year and most run on fuel oil. A mini split heat pump handles that heating load directly, room by room, without burning oil to do it. Given how often Alaska households lose power, ask the contractor about backup heat too, since a mini split still needs electricity to run.
- How many rooms can a mini split cover?
- A single outdoor unit can run several indoor heads at once, so it depends on the system. Each indoor head heats the room it's mounted in, so the right count comes down to how many rooms you want heated and how they're laid out. A contractor can look at the house and size the system to it.
- Can a mini split heat a whole house?
- It can, if there's an indoor head in enough of the rooms and the system is sized for the house. With winter nights here averaging 27°F, the equipment has to be matched to that cold, not just to square footage. A contractor will need to look at the layout and do that sizing before promising whole-house coverage.
