Super tune up performed today on a Goodman straight cool condenser with air handler installed in 2022. All electrical connections are tight with no corrosion. Heat strips are pulling proper amperage. X13 blower motor is acceptable. Blower wheel and evaporator coil are clean. Compressor and condenser fan motor are acceptable. It's is currently 50 degrees outside and technician is unable to get accurate refrigerant readings due to the outdoor temperature. Outdoor unit was washed and waxed. Highly suggest adding an r19 insulation level on top of the already existing attic insulation.
