Preformed a maintenance on a Daiken mini split. Indoor unit: I checked the filter, I cleaned the filter, I checked the coils, I checked the cooling temperature and the heating temperature, I checked incoming voltage. Outdoor unit: I checked amps on the compressor, I checked behind the disconnect, I checked drain line and vacuumed the drain line, I cleaned the coils, I checked incoming voltage, I checked the temperature on the line set. Everything is working properly at this point in time.
