Preformed Dryer Vent Cleaning Preformed single system heat maintenance on 2018 heat pump. I tested all electrical components on inside air handler. All electrical components tested within manufacturer specifications. I proceeded to the outside to test all electrical components. All components tested within manufacturer specifications. The only concerns I found were the amps were starting on the high side of the start amps for the compressor. 60/72 amps. The unit could benefit from adding a hard start kit to help bring the amps down. Also I noticed he system doesn’t have surge protection. Unit was cooling upon departure.
