We called Alaskan Home Services to repair our furnace and ac unit and the service was good. They came out promptly and fixed the issue and they told us if we ever need any help to call them again. We called them a few months later to have our furnace cleaned and they let us know that our technician quit.
The next available tech lived 70 miles away and it was hard to get a hold of them, but once we did, they came out the next day. Alaskan Home Services is good, solid company and I would recommend them if you need to use them.
