Geothermal equipment uses a water source instead of an air-source condensing component. Geothermal HVAC is particularly efficient for high-energy use buildings such as those built for education and health care. Because schools and hospitals have consistently high occupancy levels, geothermal energy efficiency offers operating cost savings. In addition, educational and healthcare facilities can use geothermal systems to “share the load” when parts of the building need heating and other parts of the building need cooling. AAON has geothermal equipment from 0.5 tons to 240 tons!
