2020 Trane 2013 Bryant Indoor units: I checked amps on the fan motor and heat strips, I checked the float switches, I checked the coils, I checked the filters, I checked drain pan, I checked the drain pump, I checked the heat coming out of the vents. Outdoor units: I checked the coils, I checked the compressors and fan motors I checked the capacitors, I checked the temperature on the line sets, I looked into the units and behind the boards. Everything is working properly at this point in time.
