An open-loop geothermal system is a type of heating and cooling that pulls water directly from a well or pond, passes it through a heat exchanger, and then discharges it back into the ground. Because the water temperature remains stable at roughly 55°F, it is much more efficient than traditional air-source Mobile Home AC Condensers. This technology requires a reliable water source and specific Water-Plumbing considerations to prevent mineral scaling. While ACIq specializes in air-source units, open-loop systems are a premium option for properties with abundant water. They offer some of the lowest operating costs of any HVAC technology available. Regular maintenance of the filter and discharge point is necessary to keep the loop flowing freely. It is the ultimate "natural" way to keep a home comfortable year-round.
