Alaskan Air Conditioning & Heating originally installed the AC unit on my house when I first moved in. Several years later that AC was damaged in a hail storm so I had them come back out to replace the broken unit. Everything went off just fine, however I was just on the roof and I noticed that the joints on the conduit of the unit they installed came undone, so I will be calling again today. But I would recommend them to anyone and continue to use the service.
