Ground-Source Heat Pumps: Its Future is Now!


Welcome to the Long Island Geothermal Energy Organization (LI-GEO) web site.

We are a nonprofit association specifically interested in promoting the use of ground-source heat pumps to heat and cool buildings on Long Island. Other terms used are “geoexchange” or “geothermal” heating and cooling. We will use this latter term.
