Comfort maker straight cool condenser with air handler installed in 2016. Electrical connections are tight with no corrosion. Heat strips are pulling proper amperage. X13 blower motor is acceptable. Blower wheel is very dirty and needs to be cleaned. Biological growth is present inside the air handler. 45/7.5 dual run capacitor is out of spec and needs to be replaced. Compressor and condenser fan motor are acceptable. Refrigerant levels are in range. Highly suggest replacing the failure capacitor and adding a compressor saver and a germicidal UV light.
