Came out to call. I was out to do the maintenance recently on the units. Customer said East unit had stopped working and was making a noise. I checked system over and found the system had locked itself out. I reset condenser and cooled down the compressor. System came back on but was freezing up quickly. I checked equipment in attic and found the variable speed motor not ramping up like its supposed to and was barely blowing any air. I reset module plugs and cycled it on again. Motor started and was operating properly. Discussed with customer about the module on the motor possibly malfunctioning, but it was operating after I reset the plugs. We talked over options, and customer wants to wait and see how it operates over the weekend. I will keep ticket open and have the model number on file in case I need to order it. Return to install previously recommended ecm motor replacement recommended by Isaac. Install new motor tested amp draw and verified motor is ramping up to correct speed.
Performed preventative maintenance on 2 AC systems. Took out and washed customers electrostatic filters. While I let those dry I inspected the blower assemblies, electrical components, wiring, evaporator coils, drains, ducting, and overall condition of equipment in home. Reinstalled filters. Checked and tested thermostat operation, amps, temperatures and pressures of condensers. Checked capacitor, compressor, contactor, fan motor, and control boards. Cleaned condenser coils thoroughly. Both systems are cooling properly within manufactured specifications at this time.
Arrived to not cooling well service call performed system evaluation. Found system slightly low refrigerant. Spoke with customer. Customer chose to add refrigerant. With customer approval added 14oz r22 to system. System cooling at this time. Washed condenser. Customer will replace filters. System running as designed. If system becomes low on refrigerant in near future I suggest leak repair be performed.
