Responded to no cooling complaint on upstairs system in a two-system residence with 9-year-old equipment. Upon arrival, confirmed thermostat was calling for cooling with setpoint at 74°F while space temperature had risen to 77°F. Air handler was operational with blower running, but supply air was not adequately cooled. Performed diagnostic testing of the system and measured supply air temperature at 62.8°F at the ductwork in the attic space, indicating insufficient cooling capacity. Conducted refrigerant charge analysis using digital gauges, which revealed a low superheat reading of 0.22°F, confirming a refrigerant overcharge condition or possible restriction in the system. The abnormally low superheat suggests liquid refrigerant was reaching the compressor, creating potential for compressor damage if left unaddressed. System restored to proper cooling operation with appropriate refrigerant charge levels verified and airflow confirmed adequate throughout the conditioned space.
Responded to no cooling complaint on upstairs system. Upon arrival, found 15-year-old air conditioning unit blowing warm air.
