100% Geothermal Development Shines in Atlanta, Georgia

Sustainable Living Carla Morris March 29 6 minutes reading time

Great teamwork wins again when it comes to real estate developments melding ultra-efficient geothermal heating and cooling with style. A recent standout? The Gardens at Arbor Springs in Newnan, Georgia. This 55+ (or “55 and better”) enclave of 71 homes pairs eye-popping aesthetics with superior energy efficiency. 

Longtime Southern Living enterprise McKinney Builders turned the vision into an award-winning reality with the help of Enertech, a leading manufacturer of geothermal heating and cooling systems. 


In 2020, McKinney launched the Gardens’ show-stopping aesthetics in greater Atlanta. The courtyard “cottages,” reminiscent of English country style, feature lots of natural light, vaulted ceilings, reclaimed wood accents, classic and luxury custom finishes, and white oak flooring.  

Their unique outdoor living spaces invite entertainment: 

  • Spacious interior courtyards, perfect for al fresco dining. 
  • Options for outdoor kitchens, fireplaces, and spa-like pools. 
  • 8-foot privacy wood fencing.

Residents enjoy proximity to three towns and easy access to health care, city parks, shopping, a golf club, the airport, I-85, and Atlanta.  

The Forsyth Herald called the development a “distinctly unique luxury community.” The Newnan Times-Herald pronounced it “a delight for those looking to ‘Begin A New Season.’” 


The Gardens’ fine craftsmanship and beauty tell only half the story. A quiet, low-profile GeoComfort heat pump by Enertech tucked away in each home tells the rest. Enertech manufactures units that in the colder months extract heat from the ground and use it to warm the air in your home. During the warm months, the geothermal units work in reverse. They extract heat from your home and store it underground. 


  • Use 25-50% less energy than conventional HVAC.  
  • Realize four times the efficiency of a gas furnace and two times the efficiency of an air source heat pump.  
  • On average, save $1,500 annually on energy bills, and  
  • Begin seeing positive cash flow in just one month. 

They also can expect to enjoy comfort for the long haul. Housed inside and away from the elements, Enertech heat pumps last a long time—20+ years. The below-ground components last 50+ years - even up to 100 years.   


Though relatively new, The Gardens at Arbor Springs has won multiple awards, including the Active Adult Community of the Year Award presented by the Atlanta Sales and Marketing Council of the Greater Atlanta Home Builders Association.
