System type: ICS system
System is fine but is isolated. The client did not want the system because the local agency had told him that he would have to cut trees down. He came home one day and saw that the system was installed. Since he thought that the system would not work because he was not about to cut down his trees, he isolated the system and it has been that way since 1997. The ICS unit on the roof is covered in shade due to massive oak trees. I did un-isolate the system and noted that there were no leaks at the ICS or valves.
