Arrived at the house, was informed unit #2 Trane heat pump was not cooling, checked system and found it void on refrigerant, quoted to add 2 lbs of refrigerant and perform a leak search to find the leak, quote was accepted, Performed Leak search and added 2 pounds of refrigerant today, found evaporator coil leaking refrigerant at a fast rate would not hold refrigerant, looked up parts warranty and found system still has a parts warranty, indoor air handler has started to accumulate bio growth and in very worn conditions, outside unit is worn and compressor has lost some of its potential to function because when a major leak is present some oil from the compressor does come out as well, gave option to replace evaporator coil and due to systems conditions, cost of ownership and future repair to speak with one of our comfort consultants about replacement. Chris is coming back out.
