Juneau doesn't ask much of an air conditioner

Summer afternoons here average 63°F. That's not weather that calls for cooling, and most homes in the borough go without it.

If you're installing central air anyway, for a specific room, a heat-producing appliance, or just peace of mind, any new unit built since 2023 has to meet a federal minimum of 13.4 SEER2. In a climate this mild, that efficiency floor will do more work than the system itself ever will.

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 record tells you the business exists, not that the state vouched for its skill.

For an air conditioner install, the protection comes from somewhere closer to home. In most cities and boroughs here, installing a new air conditioner needs a permit from the local building office, with an inspection once the work is done. That inspection is what checks the work, since the state registration does not.

What size air conditioner does my house need?
A contractor needs to measure your house before that question can be answered. Sizing depends on square footage, insulation, window area and how many walls face the sun, and a unit that's too big or too small for the space will run poorly either way. Summer afternoons in Juneau average 63°F, and most homes here don't run cooling at all, so a lot of houses may need less than you'd think, if they need it at all. A contractor can walk the house and work out the right size for your situation.
Should I replace the whole system or just the outdoor unit?
That depends on the condition of what's already there and whether the indoor and outdoor parts still match. Replacing only the outdoor unit can work if the indoor coil and the rest of the system are in good shape and compatible with the new unit. If the system is older or the parts don't pair well, replacing both at once is often the more reliable path. A contractor can look at what you have and tell you which one makes sense here.
Do HVAC contractors in Juneau city and need a state license to work on my home?
Alaska requires contractors to register with the state, so check that whoever works on your home is registered before the job starts. Registration is a basic protection, it means the contractor is on record with the state and can be held to that record. Ask to see it before any work begins.
