Completed no cool call. Upon arrival, customer stated that the main floor was not cooling. Upon inspection system was frozen, this was a system from 2001, this is a R 22 system. Upon inspection of the outdoor system, found that the system was low on refrigerant. R 22 is no longer manufactured. Customer also wanted us to check the basement system. This system is from 2003, it is also a R 22 system. On inspecting the outdoor system, found that this system is also low on R 22 Refrigerant. We also found that the compressor is very hot.
