On arrival upstairs system running but not cooling. Found leak in evaporator coil and showed video to customer. Emergency drain pan is very rusted, blower is dusty, and the contactor to the outdoor unit was buzzing indicating that it is beginning to wear out. Also recommended a compressor saver kit due to the damage the compressor has likely sustained from pumping low refridgerant. Due to the lack of warranty and the cost of repairs I recommended speaking with a comfort advisor about replacement before pursuing repairs. Customer will speak with his wife and call us back. I will follow up tomorrow.
