I found liquid line solenoid valve inside the condensing unit shorted, causing unit to run without a call for cooling. I wired unit to bypass solenoid valve. Valve was only used for efficiency improvement. I found system approximately 30% low on Freon. I topped off partially with 1 pound of R-22 Freon for temporary cooling. Suction: 74(44). Suction line: 68. Expect Freon will leak back out. Recommend replacing air conditioner. Repair cost may apply to new equipment. Project manager is scheduled for before 4 o’clock tomorrow. Need to call customer to confirm a timeframe.
