About Earth To Air Systems
Earth To Air Systems, LLC (ETA) was founded in 2002, in Franklin, TN, USA to develop, patent, and market direct exchange ("DX") geothermal heating and cooling technologies.
DX geothermal technology is an industry term used to describe geothermal heating/cooling systems that do not require an intermediary water exchange loop, as do water-source geothermal systems. By utilizing innovative and proprietary approaches to solve what many believed to be irreconcilable problems, ETA has shattered major hurdles typically associated with direct exchange geothermal heating and cooling systems.
ETA DX technologies have not only proven to operate at the highest known levels of efficiency, but can also require 20% to 50% less excavated area than properly installed conventional water-source geothermal technologies.
ETA DX designs utilize the most advanced components known to exist... including the environmentally friendly R-410A refrigerant. More importantly, ETA DX geothermal technologies can be installed for virtually any application... in almost any environment.
With the introduction of ETA technology, realizing ultimate levels of comfort, efficiency, and safety has never been more achievable.
