ETA Geothermal Technologies are believed to be unrivaled in terms of efficiency, comfort, and aesthetics. Earth to Air Systems is a revolutionary air conditioning system that use’s geothermal energy created by the earth’s constant temperature to both heat and cool your home or commercial space. ETA systems utilize high efficiency copper ground source heat exchangers (GSHE) that are deeply buried in the ground. Once installed, no one can see or hear the advanced ground source heat exchanger hard at work beneath the surface.

ETA technologies have attained the highest known efficiency ratings for a single-speed compressor unit under comparable strenuous test conditions. These ultra-high efficiencies can have a significant positive impact on your heating/cooling expenditures. An Earth to Air (ETA) geothermal system can reduce conventional annual heating and cooling expenses by 40% to 80%. Because the system utilizes the earth’s stable temperatures it is not subject to the significant operational efficiency losses that plague conventional air-source conditioning units.

ETA geothermal technologies provide ultimate levels of comfort in both heating and cooling modes. While the outside air temperatures significantly fluctuate, the deep ground temperature remains relatively constant. Earth to Air Systems work by using this constant temperature 'free of charge' to heat or cool air. ETA systems take advantage of this physical principal to provide cool-crisp air in the summer (typically 48-58F) and warm comfortable air in the winter (typically 90 - 100F).

Noisy outdoor equipment is a thing of the past when you install an Earth to Air geothermal system. ETA’s designer stainless steel compressor unit makes about as much noise as a household refrigerator and can be placed indoors or outdoors.
