Oceanside housing and HVAC
Coastal homes often have gas wall or forced-air furnaces and no AC, while inland homes are more likely to have central AC. Many military families rent homes near the base. Inland subdivisions built in the 1980s and 1990s have central AC with attic ducts, many on aging original systems.
Oceanside has a mild marine climate near the beach, with warmer inland neighborhoods and occasional Santa Ana heat waves. Summer highs near the beach stay in the 70s, while inland neighborhoods can reach the 90s during Santa Ana events, which also bring wildfire smoke from the backcountry.
