I arrived for a new customer no cool call. I first spoke with the homeowner and confirmed our diagnosis fee and I asked questions on how the system is preforming and where the system is located. The homeowner said the system has not been keeping up for about two weeks but it will still run. She showed me the outdoor system and the she let me have access to the indoor system as well. I set up my gauges and temperature devices and started to inspect the indoor system and outdoor system. I found the system to have a standing pressure of 139 psi on high and low side. I inspected the indoor air handler and found the evaporator coil to be rusted and cover in oil. At this time I went to ask the homeowner if she would join me in. The attack and I would like to show her what I have found. She followed me into the attic and we looked at the system. I then preformed a free leak search with soap bubbles and a electrical leak detector to pin point the leak. We found the leak on the suction line rig
