Can a geothermal system be retrofit?
Yes. The process is similar to new construction in several ways. First, we still calculate an accurate heat load using Manual J. Second, we correctly size the equipment to meet the homes needs. The last part is analyzing the current duct work, including the cold air returns. Loops are put into the ground and brought into the house, the same as a new construction project. The geothermal unit will replace the current furnace and air conditioning units. Top Q: You mentioned heating and cooling. Does it do both? A: One of the things that makes a heat pump so versatile is its ability to be a heating and cooling system in one. You can change from one mode to another with a simple flick of a switch on your indoor thermostat. In the cooling mode, a geothermal heat pump takes heat from indoors and transfers it to the cooler earth through either groundwater or an underground loop system.
