Kenai summers barely ask for cooling at all

Summer afternoons here average 64°F. That is not weather a house needs to fight, and most homes on the Kenai Peninsula get through the year without running an air conditioner at all.

When a new central air conditioner does go in, it has to meet the federal minimum of 13.4 SEER2, the same as anywhere else. Given here how mild the summers run, that unit will spend most of its life idle, ready for the handful of warm afternoons that call for it.

Alaska requires contractors to register with the state.

Registration puts the business on file with the state. Nobody tested the contractor's work to get on that list, and there is no license number that says the state stands behind the job. It just means the state knows the business exists.

For an air conditioner installation, the protection here comes from the local building office, not the state. Most cities and boroughs in this area require a permit before the unit goes in, and an inspection once it's done. That inspection is what actually gets checked here.

What size air conditioner does my house need?
A contractor can tell you after doing a load calculation on your house, and that's really the only way to get it right. Square footage alone doesn't answer it, because insulation, windows, and how the sun hits the house all change the number. Worth noting that summer afternoons in Kenai average just 64°F, so cooling load here is small compared to most places, and that changes what size makes sense for your house.
Should I replace the whole system or just the outdoor unit?
In most cases you replace both together. The outdoor unit and the indoor coil are matched to work at a specific efficiency, and pairing a new outdoor unit with an old indoor coil usually means you lose that efficiency and can shorten the life of the new equipment. A contractor can look at the age and condition of your indoor coil and tell you whether it can stay.
Do HVAC contractors in Kenai 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 fair question to ask any contractor bidding your job, and one who does this regularly will have the answer ready.
