GeoCayman is a division of NCB Group and was launched in 2013 due to the growing demand from consumers for more energy efficent cooling systems. With rising fuel prices and Air Conditioning accounting for 80% of electrical bills, NCB and GeoCayman joined forces to provide its clients with a solution using renewable energy. GeoCayman is the exlcusive dealer of GeoComfort Geothermal systems.

Unlike conventional air conditioning systems, GeoComfort geothermal systems use Cayman’s saturated earth and cooler ground temperatures to significantly reduce your energy consumption for cooling your home or office.


This clean, quiet technology has been called “the most energy efficient, environmentally clean and cost-effective cooling systems available today” by the Environmental Protection Agency.


With savings of up to 50% on cooling costs and an equipment life of 3-4 times longer than conventional a/c units, using a GeoComfort system is a win-win for both your finances and the environment.

GeoCayman is proud to be an Energy Star Partner

GeoThermal Cooling

​How It Works


So how does this work exactly? Heat is efficiently removed from the home and transferred to the water in the vertical closed-loop system buried in the yard. This heat is easily dispersed in the cool ground water that abundantly saturates the island.   The cooled loop water returns via the buried loop, back to the unit, ready to start the cycle again.


This transfer of heat to the cool ground works with superior ease compared to traditional air conditioning units of the past. Rather than forcing “heat-to hot air” like conventional A/C systems, geothermal cooling units provide the highest comfort level while using 30 to 50% less electricity.
