Geothermal heat pumps are known for their exceptional performance, efficiency and durability. As a factory-authorized dealer, we have access to a full line of geothermal heat pumps and state-of-the-art split systems manufactured by Bryant. Designed for open or closed loop applications, these systems exceed Energy Star standards. Look for models with a coefficient of performance (COP) around 4.7 in heating mode and an energy efficiency rating (EER) up to 31.5 in cooling mode


Geothermal systems use the ground or an on-site water source, such as a well or pond, to collect warmth in the winter and to release heat during the summer. Geothermal energy is particularly attractive in our area thanks to Hilton Head’s mild climate and unique geography. Bryant heat pumps provide heat and air conditioning throughout the year. Some models generate hot and cool water for use with baseboard heaters, hydronic equipment and chillers. Choose from duel-use heat pumps, units that only provide heat and split systems that work in tandem with most furnaces and air handlers.

Bryant’s geothermal products deliver exceptional performance and efficiency. Two-stage compressors and variable speed blowers operate quietly and use less energy. These systems are charged with ozone-safe Puron refrigerant. Plus, all equipment comes with Bryant’s industry-leading 10-year warranty on the compressor and major refrigeration components and a 5-year warranty on secondary parts.

Our NATE-certified technicians can help you select the ideal system for your home and your unique heating and cooling needs. Call our office to learn more about our geothermal systems and HVAC services.
