Does a Mount Laguna cabin need a different kind of system than a coastal San Diego home?
Yes, fundamentally. Mount Laguna's mild summers mean cooling capacity matters far less than it does anywhere else in the network, while genuine alpine winter conditions mean heating performance is the priority. We spec cold-climate heat pumps rated to maintain output well below freezing, and given how isolated the area gets during winter storms, battery backup is worth serious consideration for keeping heat running through a power outage.
