Upon my arrival in Elgin I did AC Maintenance. evaluated 2 heat pump systems. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found the pressures for the condenser on the left side of the house low on refrigerant I was approved to add refrigerant, I ended up adding 4lb’s and the pressures are now at manufacture recommended levels. I also recommended adding ss2 float switch for each airhandler and was approved. I recommended a cleaning of the left airhandler system and a replacement of the compressor plug and the discharge line temperature sensor wire , Joseph approved the estimate. I’ll let my office know so they can schedule a date to get the work completed. WO-TNFR517669
