Sam J - arrived to customers home and found compressor overheated. Used a water hose and called the compressor then restarted system. System is running a low suction and head pressure caused me to believe that it was low on refrigerant. System is only a year or two old and Customer is currently under renovation to their home so I suggested calling the installing company to repair the system under their warranty. Customer agreed, and reached out to the original company to no avail so he rescheduled for me to return and resolve the issue. I returned on April 7th, and began by leak, searching the system to make sure that the unit wasn’t just under charged. Unable to locate any leaks at this time so I began charging system to see if I can get my pressures right. The expansion valve would not respond to any refrigerant. That was added. My suction pressure stayed at 25 psi while the head pressure rose. Order TXV expect to have it on Monday and return to repair system. Customer a
