Preparation for a Geothermal Energy Efficient HVAC System

Geothermal Well Drilling

We specify the design of the loop field and take the ultimate responsibility for the functioning of the entire system, its efficiency, and performance. Our services include:

  • Performance of a comprehensive geothermal heating and cooling cost savings analysis.

  • Design, sizing, and placement of the geothermal ground looping/heat exchanger to achieve the most cost-effective solution.

  • Working with the homeowners and business owners directly to determine if ductwork changes and/or zoning controls are warranted.

  • The configuration of the piping, manifolds, and circulation pumps to ensure maximum thermal conductivity between the loop and the ground.

  • Sizing the system to achieve optimal configuration for heating, cooling, and humidity control.

  • Preparation of a documentation package that includes system specifications and the configuration of the geothermal HVAC system.

  • Post-installation inspection of the geothermal installation in order to ensure that the system is meeting its designed heat transfer specifications. These metrics include COP/EER, BTU output; we perform system adjustments as required to optimize its efficiency.

  • Earth River Geothermal offers the very best warranty in the residential and commercial geothermal heating and cooling industry.
