Before any new furnace or heat pump goes in, a contractor has to open up what is already there and look at it directly. The duct runs were sized for whatever ran before them. The panel was too. Neither one is guaranteed to match what a new system asks for. Half the homes in Alaska were built in 1986 or earlier (2020-2024 ACS 5-year). That figure says nothing about any single house, but it does mean an installer walking into a typical home here is often working with wiring and ductwork sized for equipment that is no longer what gets installed. The question is never just what unit fits the space. It is whether the rest of the house can carry it as is, or needs work first.

A heavier storm record means the equipment sitting outside a home has more to stand up to, from high wind to ice to sudden cold. That equipment needs to be sized for those conditions and anchored well enough that it does not shift or take a direct hit. If your county sits high on this list, have a contractor check where the outdoor unit sits, how it is secured to its pad or mount, and the condition of the unit itself.
Alaska requires contractors to register with the state.
