heat pump and furnace
I know a heat pump will only work efficiency down to a certain temp but whatever that temp is will the furnace take over automatically? Its been getting cooler and my heat pump has been doing a good job. This morning it was 22° out and my furnace was running. I checked the control and it said 'heat pump'. Is this right?
