No cool on the system located in the front of the house. System is low on Freon (410a), evaporator coil leaking, condenser coil is super dirty, blower wheel is dirty as well. Lots of biological growth inside the air duct cabinet.the breaker on the air handler is rusted and wires are burnt. No drain pan under the air handler and no type of flood protection. As of repair, we need to replace the evap coil and do a chemical wash on blower wheel and condenser. Replace breaker and install a drain pan with wet switch. Due to age 18 years old and condition of system I highly recommend to replace the system instead of spending money on repairs. Air quality in the house is poor and contaminated. Set a lead for a quote on new system for Monday morning. We should credit back customer $247 if customer get a new system.
