Upon my arrival I turned the system on and found everything to be operating the best it can with its age. I let the system run for 45 minutes trying to see if the exhaust removal system or the refrigeration pumping device were getting hot and over amping. Nothing showed any signs of them not performing properly. This is an older R22 system. I let the customer know that I could not find anything wrong with the system. Just that the pressures seem to be a little low and the system is old and not very efficient. The house isn’t used as much so they are doing to limp it along until it dies then call in for a replacement.
