two system AC maintenance Downstairs system inspected system found capacitor 50/5 reads 46.3/4.9 out of manufactures tolerance. customer had me replace. checked ohm readings for compressor good, checked amp draws good, checked refrigerant Pressures good, systems is piston with a 5.5 superheat indoor wet bulb 61 outdoor dry bulb 83 superheat good. Upstairs system tested inspected system found capacitor reading just out of manufactures tolerance 35/7.5 reads 33/7.4 Checked ohm readings for compressor good, amp draws good, checked refrigerant pressures low charged system to manufacture specifications and added dye to the system to be able to check system in fall and recommend proper repair / replacement at that time depending on where the problem is.
