On arrival system was off. When system turned on condenser made a metal on metal noise. Found dual run capicator blown. Once replaced condenser came back on but compressor would randomly stop making the noise and start trying to pump the non existent refridgerant, the rest of the time it would grind and not pump refridgerant. Found leak in condenser near filter dryer. Due to age and condition of equipment and the catastrophic nature of the equipment failure I recommended speaking to a comfort advisor about replacement. Visit is set for 9-12 tomorrow.
