Tech found multiple issues with the system, listed in order of severity: 1. Evaporator coil has a leak around one of the U-joints (see videos). 2. One 6” flex duct is disconnected at splice, venting cold air into attic. 3. Condenser coil is obstructed by dust buildup, causing high pressure. 4. Obstructed evaporator coil from dust buildup, causing air restriction. 5. Low refrigerant charge due to leak. 6. Suction line insulation has worn off and no longer serves its purpose. 7. System age (and condition); January, 1996. Tech informed customer about issues and customer approved the leak search before allowing tech to further diagnose. After finding a leak in the evaporator coil, customer requested no further diagnosis or repair. Tech recommended a system replacement; customer wants to exhaust all their options before replacing the system. Customer inquired about thermostat replacement and opted not to replace at this time. System is operating at this time.
