What's different about mini split installation in Summerhaven and Mount Lemmon?

Cabins that sit empty need freeze protection and a fall heating start-up.

Summerhaven is the mountain village near the top of the Catalina Highway on Mount Lemmon, listed at about 7,764 feet. The 2003 Aspen Fire destroyed 314 of the village's 467 homes, so much of what stands today was built after it. The 2020 Census counted 71 residents, and the ACS estimate shows no year-round occupied homes, consistent with cabins used part of the year.

Up here the climate flips. The 1991-2020 normals for the Mount Lemmon Willow Canyon station, at about 7,047 feet, show a January normal high of 49.6F and low of 33.5F, about 53 nights a year at or below freezing, and about 4 days a year that never get above freezing. Annual heating degree days run about three times the airport's. Pima County puts land at 4,000 feet and above in code climate zone 5B with a winter design temperature of 4F.

That makes a standard heat pump a question for the pro, not a default; a cold-climate model or backup heat may be part of the answer. Cabins that sit empty need freeze protection and a fall start-up. If your heat runs on propane, check the tank before winter. Summerhaven is unincorporated Pima County, so the contractor confirms county permit requirements.
