Came in becuase system was not cooling properly. When testing system found that there was a lot of refrigerant missing which is sings that there is a leak in the system. Also found electrical components completely corroded and prompt to fail. Let costumer know about this issues and presented options, including a leak search or a system upgrade. Costumer decided to only add refrigerant in upstairs. Costumer understands that there is a leak on system and electrical components a prompt to fail. System is running at this times, however there are more issues that needs to be address. Thank you for choosing TE Certified!
