The core of how a geothermal system for a home works is the set of loops in the ground that carries the refrigerant (water or a water and anti-freeze solution). The refrigerant absorbs the heat from the ground and carries it indoors to be released through a condenser coil into the ventilation system of a home. During warmer weather, the process reverses, and the indoor coil functions as an evaporator coil to absorb heat, which the refrigerant than deposits into the ground.
Although geothermal installation is an intensive process and can sometimes take up to six days to complete, the longevity of these systems and their energy efficiency makes them worth this upfront investment in time. In many cases, little drilling is necessary for installing a new geothermal system. However, there are cases where geothermal drilling in Atlanta is necessary for proper installation, as we’ll explain

In order for a geothermal system to work efficiently, its coils must be placed at least 6 feet below the frost line. At this depth, the earth’s temperature remains stable at around 54°F regardless of the topside weather. The geothermal heat pump will always has a ready supply of heat for operation.
However, the depth necessary to place the coils changes from location to location depending on the average temperatures. For warmer spots, the pipes are placed in a horizontal configuration close to the surface; this requires no drilling, but instead digging out shallow trenches so that loops can be laid down into a 6–10’ groove, then covered over. If you require the loops placed at a much lower depth, then a vertical configuration works better. In this case, it’s necessary to use drilling to go down to the required depth. Although drilling is a large operation, it creates less disruption to your property, and when the system is installed will work more efficiently at the greater depth.
The other time when it is advisable to have drilling to place a vertical loop configuration is when you lack the property space to fit a horizontal set of loops. Vertical loops can fit on most properties without problem.
You don’t need to know right now the type of geothermal loops you should have. When you contact Premier Indoor Comfort Systems for geothermal installation, we will send out a technician to survey your land and determine how best to set it up with refrigerant loops. We will then take care of all the necessary excavation and geothermal drilling in Atlanta, GA to provide you with the best possible heating and cooling system.
