Heatpump frozen up & gas furnace backup.
We have a heat pump and a gas furnace - the heat pump is supposed to act as our primary heat until temps are below 32 degress when the gas furnace then takes over. Here's the problem - the heatpump is frozen up (coils covered in thick white ice and solid ice partially covering one exterior side of unit). Fan is not running on unit, but it unit "runs" constantly and is not producing any heat. On our thermostat there is an option for emergency heat, which I would think would activate our gas furnace, but instead it seems to just activate the fan w/o any heat.
Any thoughts?? Or does anybody know how we can engage the gas furnace so we can have some heat until we can arrange for somebody to come take a look @ the heatpump?
