Ketchikan summers don't ask much of an air conditioner

Summer afternoons here average 65°F. That's mild enough that most homes get through the year without needing cooling at all. If you're installing an air conditioner anyway, for a home office, a server closet, or just to have it on the rare hot stretch, it won't be working hard.

Any new central air conditioner installed today has to meet a federal minimum of 13.4 SEER2. That's the baseline no matter where you live, and in a climate this mild, you likely won't need to size up beyond it.

Alaska requires contractors to register with the state.

That registration puts the business on file with the state. Nobody tested the contractor's work and no license backs it up, so the registration alone does not tell you whether the installation is done right.

In most cities and counties, an air conditioner installation needs a permit from the local building office, with an inspection once the work is finished. That inspection is what checks the job here, not the state registration.

What size air conditioner does my house need?
A contractor has to measure your house to answer that, not guess from square footage alone. They look at your windows, insulation, and layout, then run a load calculation to size the unit correctly. In Ketchikan this matters less than in most places, since summer afternoons here average only 65°F and homes need cooling 0 months a year. If you're considering a system at all, talk through your actual needs with a contractor before assuming you need one sized like a typical AC.
Should I replace the whole system or just the outdoor unit?
If the indoor and outdoor units were installed together and matched, replacing just one can cause problems with efficiency and performance. A mismatched system often won't reach its rated output, and some manufacturers won't warranty a pairing they didn't design. A contractor can check whether your indoor coil is compatible with a new outdoor unit before you decide. If the other unit is old enough to be failing too, mention that when the contractor looks at things.
Do HVAC contractors in Ketchikan need a state license to work on my home?
Alaska requires contractors to register with the state, so ask to see that registration before work starts. It's a basic check that takes a minute and confirms who you're dealing with. Beyond that, ask about experience with the specific job you need done, since registration alone doesn't tell you how good the work will be.
