Geothermal

Did you know you can use the Earth to heat or cool your home? Our geothermal solutions use a buried loop system to produce energy right in your back yard.

Invest in Geothermal HVAC Systems for Your Home

Your backyard has the potential to be the energy source for your heating and cooling comfort. While outdoor air temperatures fluctuate throughout the year, ground temperatures four to six feet below the Earth’s surface remain relatively moderate and constant all year. This is because the Earth absorbs 47% of its heat energy from the sun.

Geothermal HVAC systems circulate a water-based solution through a buried loop system in the ground to take advantage of these constant temperatures, which means a single piece of equipment has the ability to heat and cool your home, as well as provide some or all of your hot water.

When geothermal technology is used to heat your home:

  • Cold water circulates through the earth loop
  • Water absorbs energy from the earth in the form of heat
  • Energy is carried via the water to the heat exchanger in the heat pump
  • Refrigerant in the heat exchanger absorbs energy from the water
  • Water leaves the heat exchanger and circulates through the earth loop to pick up more energy
  • Refrigerant gas that contains the energy travels to the compressor.
  • In the compressor, the refrigerant temperature rises to 160°
  • Superheated refrigerant then travels to the air heat exchanger
  • The heat pump’s blower circulates air across the air coil, increasing the temperature of the air
  • This air is then blown through ductwork to heat your home
  • After refrigerant releases its heat energy to the air, it then flows to the earth loop and starts the cycle again

When geothermal technology is used to cool your home

  • Warm water circulates through the earth loop
  • Water releases energy into the earth in the form of heat
  • The water, now cooler, flows to the heat exchanger in the heat pump
  • In the heat exchanger, hot refrigerant gas from the compressor releases its heat into the water
  • Water increases in temperature and releases the energy to the ground
  • Refrigerant gas releases its heat energy, becomes a cold liquid, and travels to the heat exchanger
  • The heat pump blower circulates warm, humid air across the cold air coil
  • Air is then blown through ductwork to cool your home
  • Refrigerant in air coil picks up heat energy from the air and travels to the compressor
  • When refrigerant leaves the compressor, it flows to the earth loop and starts the cycle again
