| I helped put in a geothermal unit. I did the digging and back fill. Our unit is a two stage unit so it will run most of the time in the low mode and when it is really hot or really cold, it kicks into the high mode. It provides a very even temperature all the time at an affordable cost. Getting the lines filled with the right stuff at the right pressure as well as the sizing and installation of all the ductwork and unit itself was way more than I would want to undertake. | |
