I love our Geo Thermal. We live in the county and decided instead of a new furnace to install Geo thermal. We saved enough by not paying for propane to pay for the unit in 6 yrs. I would recommend this in a heart beat to anyone. Our air is not as dry in the winter so I don't have to run a humidifier as much. It also heats our water which means we are not paying as much for gas to heat our water. We used to fill our propane tank (500 gal.) once a month and now fill it maybe twice a year.
