Are Geothermal Heating Systems cheaper than forced air furnaces?


I recently moved and the house has a geothermal heating system. I got it serviced and was told it is supposed to be extremely efficient but my Hydro bill is $500 to $800 per month! How is that efficient? Has anyone had the same problem? Should I change the system to forced air? Why is it so high?

    They are considered cheaper to run, that seems like a very high bill. There may be some issue going on.

    The idea behind geothermal is that it uses ground heat is already about 40 F. So, in the summer, it helps the AC cool the house, and in the winter, your heat pump doesn’t have to work so hard to “top up” the temperature in the house. It sounds like your heat distribution system/heat pump is electric powered. If you switch the heat pump unit to an oil, propane or natural gas unit, you could save some money. Your hydro bill also includes what you’re using for lighting, cooking (unless you have a gas stove), refrigerator, etc. If you have older appliances that are not very energy efficient, you will be using a lot of electricity too.
