Cleaned and checked 3 air conditioners. Checked drains. Checked voltage and amperage draw of motors. Tested capacitors. Checked Freon levels. Cleaned condenser coils. Checked filters. Bedroom system: Compressor: 11.5A .Condenser fan: 1.45A . Blower: 6.1A .ambient: 76.liquid line: 85. suction line: 40 .metering device: Piston. Return air: 72.supply air: 52.5 .wet bulb:62 . Living room system: Compressor: 11.6A .Condenser fan: 1.2A . Blower: 6.1A,m.ambient: 78 .liquid line: 98.suction line: 39 .metering device: piston . Return air: 71 .supply air: 51.5 .wet bulb: 61 . Rear system: was reconnected earlier today. I found system 75 to 80% low on Freon. If Freon was pumped down properly when unit was disconnected (By others last year) there should be close to a full charge and the air-conditioner. System may have a Freon leak. System uses the older type of Freon that is being phased out. needs R22 Freon charge: $456. Freon leak search: $189. Freon leak repair:
