Geothermal HVAC Systems & their Benefits

Carrier and Bryant recently launched new geothermal product lines. Geothermal HVAC systems have been used for over 60 years in the US and other Western countries, and their use is growing exponentially. While geothermal systems are more expensive to install than ordinary systems, they offer two key advantages. First, they offer significant long-term cost savings. The US Department of Energy has found that they can save the average home hundreds of dollars in utility costs while the system pays for itself in 8 to 12 years. Second, a geothermal HVAC system can be designed to handle multiple needs simultaneously. For example, this kind of system can work to heat water, a pool, and a house all at the same time.  
Geothermal systems work by harnessing the natural energy stored deep underground. Outdoor temperatures may fluctuate with the changing seasons, but four to six feet below ground level, temperatures remain fairly constant year-round due to the earth’s natural insulating properties. A geothermal system works to tap into these constant temperatures to provide both heating and cooling to a building. The system consists of an indoor handling unit and a buried system of pipes called a ground loop. During the cooler seasons, the system’s loop absorbs stored heat within the ground and moves it indoors. During the warmer seasons, the system pulls the heat from the building and deposits it underground where the temperature is cooler.  Unlike ordinary HVAC systems, geothermal systems simply transfer heat to and from the earth. Electric power is only used to operate the indoor unit’s fan, compressor, and pump. When they are installed properly, geothermal systems require very little maintenance because the loop is buried underground, while the unit’s fan, compressor, and pump are housed indoors and protected from severe weather conditions.

Advantages of Geothermal HVAC Systems:

  • Higher energy efficiency and lower operating costs
  • Even temperatures and excellent humidity control
  • No noisy outdoor equipment
  • Longer life expectancy
  • Able to operate for years with little to no maintenance
  • Flexible 3-in-1 system that offers a method of cooling, heating, and producing domestic hot water
  • Reduced carbon footprint
