Tech found blower motor overheated due to a failed capacitor. Tech also found no voltage at y with a heat pump. Tech jumped out thermostat and found voltage at y. Tech recommends replacing thermostat and replacing capacitor. System is near 30 years old and tech recommends replacement. After further inspection due to age, tech found system void of R22 refrigerant. The suction port is missing and is a large hole. It is also likely the coil is leaking, but suction port would need to be replaced before further leak searching to allow system to hold pressure. Tech does not recommend doing any major refrigerant repair on a 27 year old R22 system. Tech replaced blower capacitor and system is now working in emergency heat only. Field supervisor notified.
