Our AC died on a Saturday afternoon with family visiting. The dispatcher picked up on the second ring and a technician was here within a couple of hours. Bad capacitor, fixed on the spot. Cool house by dinner.

Systems are sealed; loss means a leak, most often at the evaporator coil, a fitting or a corroded line set near the ocean.
