2004 trane air conditioner. System low on r22. Found leaks in 2 spot on the evaporator coil. Went over options on page hj1 and hl1. Also discussed replacement. Customer decided to go forward with estimate. Jamie scheduled today between 1-2 pm. Chose hj1 for temp cooling. Charged system to 20 degrees superheat. Temp drop is 18 degrees. All okay at this time.
