Completed with no cool on a 1999 trane 4 ton gas upflow in closet r22, found bad capacitor, after installing a new capacitor, found unit slightly low on r22 refrigerant and fan motor shaking showing wear. Due to age and un able to do all preventative repairs, replacement is recommended. Customer wants unit to keep running till he gets the money to replace unit. Replaced capacitor only at this time. Unit colling at this time.
