Today I came to Mark’s Redstone home to perform the annual ac system tune up and inspection and to quote for a new water heater. Ac system tune up and inspection: Upon Ac inspection and service of the 11 year old system I tested temperature drop, relative humidity, air flow, motor and fan, compressor, capacitor, contactor, evaporator and condensing coils, refrigerant levels, and general system operation. The compressor, fan, capacitor, and contactor are all working well within manufacturers specifications. The condensing coil is plugged and causing the system to run very inefficiently and causes stress to the compressor. The refrigerant levels look good but I can not tell for sure until the coil is cleaned.
