I purchased a new home around 6 months ago, right at the end of summer. Through winter, my electrical bills were sky high. About a month ago I turned on the AC for the first time. After a day I noticed that the cold water coming from my tap...was no longer cold. It was hot in fact. After much trouble shooting I discovered that the geothermal system at my house pumps up from my well and dumps back into the very same well. From everything I can tell this is not the way geothermal is supposed to be set up. What steps do I need to take to fix my system? What is more effective a dry well or a pond. Adjacent to my home is an empty lot with a well. Should I purchase the lot and use that well as a dump? How much does a dry well cost? How large of a dry well do I need? Should I just pull out the geothermal and put in a conventional HVAC?
