Cooling tune up performed today on an Ameristar heat pump with air handler installed in 2017. All electrical connections are tight with no corrosion. Evaporator coil and blower wheel are dirty and should be cleaned. Refrigerant levels are slightly off due to the dirty evaporator coil and blower wheel. Compressor and condenser fan motor are acceptable. Outdoor unit was washed and waxed. Highly suggest a level two duct cleaning that will clean all of the ducts in addition to cleaning the blower wheel and the evaporator coil.
