2 heat pump Tune Up/Maintenance check complete. Left customer with replacement filters. Tested upstairs system and found no issues. Main level air handler has a fault in the blower motor controller and a dirty blower wheel. Recommend repair and cleaning. Main level thermostat is not designed for a heat pump system, so it is only utilizing aux heat. Outdoor unit reversing valve is stuck in ac mode so that is probably why that thermostat is in place. Compressor and fan have high amp draw indicating wear. Fins are worn. Due to age and condition of system, recommend upgrading to a more reliable and efficient system.
