CaliforniaGeo is the moniker for the California Geothermal Heat Pump Association. We are advocates for tapping the abundant and renewable thermal resource of the shallow earth to heat and cool buildings of all types, large and small. Our equipment is the most efficient means known for transferring thermal energy and is flexible enough to handle any delivery technology, from ducted air to radiant coils, to radiant panels, to chilled or hot water storage. Ours is also the longest lasting HVAC equipment available, often with above-ground lifetimes exceeding 25 years, and below-ground lifetimes approaching perpetual. Geothermal heat pumps are the greenest you can become, while delivering the lowest LCC (life cycle cost) of any HVAC technology.
