Arrived on site and performed AC diagnostic on two system Lennox from 2007. Upon arrival Tony stated that the FAU breaker keeps tripping and the AC breaker keeps tripping for both units. Turned on downstairs system and proceeded to outdoor unit and found suction line was freezing over within two minutes. Proceeded to attic and found the indoor blower motor has failed and is no longer blowing air over the evaporator coil causing freezing temperatures. Installed new dual secondary motor control but motor is still over amping due to old age and wear and tear. Proceeded to outdoor unit for downstairs and found the system was slightly low on R22 charge and the dual secondary motor control was out of range. Began diagnostic on upstairs system and found that it was operational at this time although electrical components were not in good condition unfortunately. Dual secondary motor control Was also out of range and starter was severely burnt and pitted on contact points from high power usage.
