Homeowner stated that the condenser fan would turn off after a while of use. Per my evaluation of a 2011 3.5 ton trane HP, I found these major issues. Blower wheel has a heavy layer of dirt, dust and debris which reduces optimal airflow to the house. Heavy biological growth on the indoor unit. Liquid line/evaporator coil leaks detected. No drop down ladder for ease of access to the indoor unit. Return ducting at the plenum needs to be reveled. Outdoor unit is extremely un-level which compromises the compressor due to the proper amount of oil being able to be where its suppose to be for proper performance. Scorching on primary Electrical control contactor. Shorted out lizards ontop of the contactor and capacitor. Compressor RLA is high. Temperature of the suction line in heatmode indicates undercharge. No manufacturer warranties. System trips on thermal overload due to the aforementioned issues with the compressor and refrigerant. Bringing this all to the attention to the homeowne
