Arrived to no cool. Customer states that the system is freezing up. Evaporator coil and blower wheel are both very dirty and causing very poor air flow. Customer is upset that the previous technician sold him a soft start for the outdoor condenser without addressing the air flow issue. Coil is very corroded as well. Customer would like to speak with a comfort advisor to get an estimate for a new system before deciding whether to fix this 14 year old straight electric system or replace it.
