For this evaluation the customer system was not cooling, he indoor and outdoor were both running however it was only blowing out hot air. When I showed up these system was off and they just had the blower set to on so I turn the system on gauged up to measure refrigerant where I had a 36° superheat and a target of 30° indicating the system is low on refrigerant. A courtesy leak check to the evaporator coil on the pancake unit and was picking up refrigerant particles in the air however due to evaporative coil being pushed up into the ceiling I was unable to pinpoint exactly where the leak was coming from. Let's go to the customers about what I found and their options and they elected to go ahead and speak with a project manager about system replacement and pricing for a new heat pump or a mini split.
