When should auxiliary heat turn on?
Auixiliary Heat will turn on automatically when heat can no longer efficiently transfer heat from the outside air to heat pump. This is when the outside is around 35-40 degrees and the indoor temperature is around three degrees cooler than the thermostat setting.

Is auxiliary heat more expensive?
Auxiliary heat can handle more extreme temperatures since it uses electric heat strips. What this means, unfortunately, is that it’s more expensive than the conventional heat provided by a heat pump. … While a gas furnace is not as efficient as a heat pump, it is more efficient than a heat pump using auxiliary heat.
How much more does auxiliary heat cost?
