The customer would like one indoor unit on a room removed off the wall for a period of time while the demolition gets done and finished then would like it placed back on the wall. The only issue with this is you can not isolate that one unit with the branch box that is installed. We would need to recover all the refrigerant out of the system then remove the unit but the other 3 units will not work. Gave the estimates to the home owners for the work. She will call us when she is ready to get the work done.
