There are two R22 gas packs and a Carrier mini split on site. Dining room is meeting setpoint. Kitchen is not. Tech inspected kitchen unit. Kitchen is maintaining only 80 degrees. Setpoint is 68. Blower and all four fan motors are running. Compressor 1 and 2 are overheated due to being extremely low on R22. Compressor 3 has been converted to R-438A and is running normally. Compressor 4 is still R22 and is running normally. Tech recorded pics of refrigerant pressures and compressor amp draws. Six 24*24*2 filters are very dirty. Condenser coils are very dirty. 10uf fan capacitor 1 is reading low at 5.5uf. Fan capacitor 2 is reading low at 5.1uf. Fan capacitor 3 is reading low at 6.5uf. Fan capacitor 4 is reading low at 5.57uf. Tech recommends replacing four 10uf fan capacitors. To get system running, tech recommends cleaning condenser coil, recovering trace R22 on compressor 1 and 2, recharging with 7 lbs of R22 per circuit (14 lbs total), and coming back to do a full service on all
