CaliforniaGeo is a trade association supporting the use of geothermal heat pumps.  We are glad to answer conceptual questions about the technology as our way of advocating for proper design, installation, and commissioning of these systems.

Though we feature a number of installation examples on this website, we cannot make specific recommendations for your project.  Instead, we encourage you to make use of our Member Directory to locate professionals who deal with proper installations, every day.
