Found unit not kicking on due to bad voltage absorption system. Replaced voltage absorption system and signed customer up for 1 system maintenance plan. Voltage absorption system was under warranty so I credited $75 off the repair. Went ahead and did summer maintenance for customer. Left customer with replacement filter. Mechanical and electrical components in good shape. Found system low on 410a, recommend recharge. Recharged system to 10 degrees superheat. Chemically washed condenser coil. System operating at this time.
1 system ac tune up complete. Didn't change filter, left customer with replacement. Added chlorine tablets to evap coil drain pan. Found evap coil door came loose, sealed it up for maximum airflow. Found very little insulation on outside suction line that was old and breaking down. Cut off old insulation and put new insulation on suction line outside. Found voltage absorption system running very weak, recommend repair. Found wasps living in condenser coil, removed and killed them for customer. Chemically washed condenser coil and applied rust proof waxing. Found no surge protection, recommend adding on to protect unit from lightning strikes and power surges. System operating at this time.
1 system ac tune up complete. Left customer with replacement filter. Added chlorine tablets to condensate pump. Found light rust on evap coil. Found blower motor controller running weak out of manufacturer specs. Recommend repair. Found blower wheel dirty, recommend cleaning. Found damaged fins on condenser coil. Found part of suction line outside missing insulation, added insulation to it. Found high amp draw on compressor and fan. Found voltage absorption system running weak, recommend repair. Due to age and condition of system, replacement of system would be a better option than repair. Chemically washed condenser coil and applied rust proof waxing. System operating at this time. Customer declined repairs at this time.
2 system ac pm check complete. Changed filters. Added chlorine tablets to upstairs drain line and basement condensate pump. Checked mechanical and electrical components, all in good shape! Gave condenser coils a chemical wash and applied rust proof waxing. Systems operating normal at this time! Recommend surge protection to protect units from lightning strikes and power surges. Recommend apco air purifiers for improved air quality.
