I have been an Alaskan customer for maybe 15 years. They installed and maintained a fantastic Trane system that wore out, so I just (2022) had them install a Lennox system. They persisted until all issues were ironed out. We lacked AC for maybe 6 hours in early morning of a May Day, so no problem. They know what they are doing. My guys are Dylon L., Sam H., and David Ösman. Ask for them by name.
