North Heat pump was showing heavy signs of frost and the thermostat was brining on the electric heat frequently. Went into the programming for the thermostat and made some adjustments. Puron levels appear normal, thermistor is reading correct temperature, and the defrost board goes into defrost when it’s supposed to. Temperature rise is also within normal range. Capacitors for both heat pumps were getting weak. Replaced under parts warranty. Both systems appear to be operating normally at this time.
