I have a gas furnace and was told I should get a “heat pump”. What is it?
You have a natural Gas furnace because it was the most reasonable value to heat your home. In some areas of the country, electricity is less expensive than natural gas, & in those areas a heat pump system may be a better value. A Heat pump is like running your air conditioner in the winter, But running the heat transfer to the interior of the home, instead of outside as in the air conditioning mode. They work without natural gas & run entirely on electricity.
