Our customers are occasionally surprised to discover that geothermal power can be used to keep a house cool. Because the term geothermal connects with heat in people’s minds, it seems strange for them to think that geothermal power could provide cooling. However, a geothermal heat pump is just as effective at cooling a home as heating it.
Geothermal systems work similar to other heat pumps: they move heat from one place and put it in another. In heating mode, they take heat from outside and put it inside. In cooling mode, the process reverses, and they remove heat from inside a home and put it outside. The difference with a geothermal system is that the “outside” is underground. Loops carrying refrigerant deposit the heat taken from indoors and place it in the ground approximately 6–10 feet below the frost line, where the temperature remains stable.
Not every home has the right conditions for a geothermal heat pump to work. To find out if geothermal cooling in Sandy Springs, FL will keep your home comfortable and energy efficient, contact our specialists at South Air Inc. today and schedule an appointment.
When geothermal is the right choice
The technology of geothermal energy continues to advance, making it more widely available for homes. To work effectively, a geothermal heat pump must have sufficient ground space for the loops that carry the refrigerant (a solution of water and antifreeze) and the right soil conditions to allow the refrigerant in the loops to deposit heat from inside the home.
Loops can be laid in either a horizontal or vertical configuration. The horizontal configuration is more efficient and only needs to be placed about 6 feet down into the ground. However, this layout takes up more space than vertical loops, which go down into deep drilled holes. Vertical loops are helpful for smaller properties, or in situations where the loops must reach deeper to access the stable temperatures that make geothermal cooling so efficient.
If you live near a body of water such as a lake or river, you have the option for a water-source heat pump, which operates the same as a geothermal cooling system except that the coils go through the water. An air conditioning technician will determine which system will deliver you the best comfort while fitting in with your budget plans.
