p 1 - System is low on refrigerant R-22. I have spoken with Susan, and she is selling the house. She said the house will go on the market in a week. I advised her to speak with her real estate agent and figure out what would work for them. She would like me to and a quote to her to replace the system and ductwork so she can factor the price into her decision. Trip 2 – R-22 added. System at 10.5 degrees sub cooling.
