Air handler typically has auxiliary/emergency heat strips (resistive electric heat elements) that are energized by thermostat when heat demand is high, when you manually select emergency heat, or by heat pump during its defrost cycles. Some heat pumps have an outside thermostat to shut unit down during low temperatures, during which time you are totally dependent on auxiliary/emergency heat from source other than heat pump. Circuit for air handler may include more than one breaker. Circuits for air handlers with heat strips generally have very large amperage requirements, more than the external heat pump itself. Breakers deteriorate over time, reducing capacity. There may be an issue in the air handler itself, including internal heat strips, fan, or wiring. Due to the high amperage/voltages, the potential for damage/fire/injury is great. if you don't know what you are doing you should consult an expert
