Wrightwood is alpine, not desert. Summer highs typically peak in the high 80s, occasionally hitting low 90s during heat waves. AC use is light here, and many Wrightwood homes never installed central air because the mountain climate handles most cooling demand naturally. When AC installation calls do come in, they are usually mini-split installs in single rooms (master bedroom, home office, vacation rental main living area) rather than whole-home central systems. Mini-splits make sense in Wrightwood for three reasons: install cost is lower ($2,000-$4,500 per zone vs $5,500+ for central), no ductwork needed (most Wrightwood cabin-style homes have minimal duct infrastructure), and they work bidirectionally as cold-climate heat pumps that can supplement the propane furnace in winter. For Wrightwood vacation rentals where the home sits empty for weeks at a time, mini-splits are easier to manage than central systems because they can run on individual room remotes without conditioning the whole house.
