I was called out to Kelly’s house for a Homecare maintenance as well as clean the wheels in all 4 systems and installing a wet switch on the basement system. During the evaluation we discovered the upstairs system wasn’t working properly and after speaking with tech support we will need to replace some parts on the evaporator coil and potentially the compressor once the initial repairs are performed and the system is tested afterwards but otherwise the other systems are working well. I was unable to replace the thermistors today because the parts were unavailable but once I return for the other repairs we can install those as well.
