On arrival set unit to call for cooling.found system has a leak .unit is 15 years old with r22 system .customer is getting an estimate to replace tomorrow.unit is not operating at this time . Warrantied per Darlene
Upstairs unit not operating outside because the voltage absorption system was open for the compressor. I replaced it with 40&5 uf dual run cap and tested the unit. Unit uses r22 refrigerant and the pressures were lower than normal. I went into the attic and had 87 return and 69 supply air temperature. I opened up the blower compartment and felt refrigerant oil inside of the evaporator drain pan. I spoke with the customer about this because it is cooling but most certainly has a leak in the coil. I had to make an estimate to replace the coil and document what I found to protect myself. Otherwise the unit is operating normal.
