I arrived for a blue club member no cool call. I inspected the system and found it to be completely frozen over. I cycled the furnace on and melted all ice. I then recommended to preform a leak search to find the leaking component and replace or repair the part. We decided to not preform a leak search at this time due to the homeowner trying to sell their home. I added thee pounds of R410A to the system and set the systems subcooling at 15 deg.
