A mini-split here runs on heat, all year
Ketchikan doesn't give a mini-split a break. Winter nights average 33°F from December through February, and summer afternoons only reach 65°F. There's no real cooling season here, but the heating side of the unit works all twelve months.
A new mini-split still has to meet the federal minimum for split-system heat pumps, 14.3 SEER2 for cooling and 7.5 HSPF2 for heating. In a place that asks for heat almost every day of the year, the HSPF2 number is the one doing the work, since the unit rarely gets to lean on the cooling side instead.

Alaska requires contractors to register with the state.
Alaska's registration is a business record, nothing more. There's no trade exam behind it and no license number that means a contractor was tested on this work. It tells you the business is on file with the state, not that anyone checked what they installed.
For a mini-split, the protection comes from somewhere other than the state. In most cities and counties here, an installation like this needs a permit from the local building office, with an inspection once the work is done, so someone outside the contractor's own crew looks at what got installed. Where that rule applies, it's the permit and inspection doing the checking, not a license.

- Is a mini split worth it?
- For most Ketchikan homes, yes, especially if you're heating with fuel oil now. A mini split is a heat pump, so it moves heat instead of burning fuel to make it. Homes here need heat all 12 months of the year, and a unit manufactured today has to meet a federal minimum efficiency rating for heating in that kind of cold, so it's built to keep working through the season, not just on mild days. A contractor can look at your current heating setup and tell you what to expect for your house.
- How many rooms can a mini split cover?
- A single indoor head is built to heat and cool one room or one open area well. If you need more rooms covered, you install a multi-zone system, which is one outdoor unit running several indoor heads, each with its own thermostat. How many zones you can run off one outdoor unit depends on the equipment and the size of the spaces, so a contractor will work that out room by room for your house.
- Can a mini split heat a whole house?
- It can, but it takes the right number of zones placed in the right rooms, not one indoor unit trying to cover the whole floor plan. Homes here need heat all 12 months of the year, so the system has to be sized for sustained cold, not just a mild afternoon. A contractor can map out how many indoor heads your house needs and where they should go to actually reach every room.
