If you’re thinking about upgrading the HVAC system in your Brunswick, Georgia, home, consider installing a geothermal heating and cooling system. They’re one of the most energy-efficient heating and cooling systems on the market today and use 100 percent renewable energy to operate. Geothermal heating and cooling systems are versatile, have long lifespans, and are inexpensive to operate compared to traditional HVAC systems.


Geothermal heat pumps not only heat and cool your home, but they can also provide you with hot water. A desuperheater, a component of the geothermal system that generates hot water, collects extra heat from the heat pump and deposits it directly into your hot water tank. The desuperheater only works when the pump is running, which means it can’t provide 100 percent of your hot water. Rather, it can supply between 50 percent and 60 percent of your hot water needs. Your water heater will take care of the rest.

Long Lifespan

Geothermal heating and cooling systems have relatively few moving parts. Furthermore, most of their major components are buried underground, protecting them from damage and helping to extend their lifespans. The heat pump’s components located inside your home typically last about 25 years — quite a bit longer than the 15-year average lifespan of a traditional HVAC unit.


Geothermal heat pumps deliver stable temperatures more efficiently than traditional HVAC systems, resulting in less energy usage overall. When running, a geothermal unit uses about one-sixth the amount of energy that a traditional furnace does and about half as much energy as a traditional air conditioner. More savings are realized with the use of a desuperheater to heat your water. While geothermal units cost more to install than traditional HVAC systems, heating and cooling will save you thousands of dollars in reduced energy bills, helping you recoup much of your initial installation expense.
