Cost to run air conditioning in Alaska
Air conditioning in Alaska
Barely a cost at all
Alaska has effectively no cooling degree days in a normal year, so central air conditioning is not something most households run or pay for. A figure in dollars would imply a bill that does not exist. Heating is where the money goes here.
Common questions
How much does it cost to run AC for an hour in Alaska?
If you ran one, about $0.60 an hour for a 2.5-ton unit at Alaska's 28.83¢ per kilowatt hour. In practice almost nobody does — Alaska has effectively no cooling degree days, so the hours never accumulate.
What does air conditioning cost per summer in Alaska?
Essentially nothing. Alaska has effectively no cooling degree days in a normal year, so central air conditioning is neither common nor a meaningful part of a household bill here.
Is it cheaper to leave the AC on all day or turn it off?
Turning it off while the house is empty is cheaper. An air conditioner works against the temperature difference between inside and outside, so a warmer empty house loses less heat gain than a cool one, and the extra cost of cooling back down is smaller than the saving.
