Our air went out late in the afternoon, We called Alaskan and our tech (James) came out the next day. He spent several hours in a very hot garage, trying to diagnose the problem. He did, replaced the part, but realized there was a second issue, which still stopped the unit from running. The next morning, he brought a second tech (Jerry) with him and after a while,(again in a very hot garage), managed to get the unit running.
However, we did require a new unit, since we managed to get 16 years from our  old one, (maybe due to Alaskan servicing it since 2004) which I understand is really a good run.

Our compliments are to Alaskan and especially to James, who was not only caring, competent and efficient.
