Q. Who are these people who keep pestering me about switching from Duke to some other gas provider?

A. They are alternate fuel providers that may be able to save you money on the Natural Gas you use to heat your home. They sell you the NG at a fixed rate over the year. Duke sells you the NG at different prices thru the year based on their actual cost at the time of delivery.

Q. How does a heat pump work?

A. A heat pump pulls heat out of your home in the summer, just like an air conditioning system. In the winter, the heat pump captures heat from the outside air and transfers it to your home. (Yes, even cold air has heat energy in it.) A blower fan then pushes this heat through your ductwork and your vents.
