I performed the cooling evaluation on 2 systems (kitchen,living room). The living room system has a very dirty heat transfer media coil and a low voltage enhancement system. The kitchen system has a dirty heat transfer media coil. Both systems are very old. I spoke with the client about her options repair vs replacement and I let her know my recommendation would be to replace and not put money into repair because these system will probably not last to much longer. They both are cooling and don’t have major issues at this time but are past their expected life span and the client agreed and will let us know if she has any issues .
