We just bought an old house with oil heat. It is insanely expensive, and have been considering changing to geothermal. DH talked to someone who has had major problems with geothermal- multiple things needing to be replaced that has been very expensive.

Do you have geothermal? If so...
1. How do you like it?
2. What are the problems?
3. How much do you pay in summer/winter? (Also please give an idea of house size and climate.)
4. Would you do it again?
