New Orleans Geothermal Air Conditioning and Heating


Until 2015, the federal government is issuing tax credits of 30% of the cost of Geothermal Air Conditioning.  There is no cap on total credit.  As a result, many of our customers are inquiring about the advantages, disadvantages, logistics and feasibility of converting their existing system to geothermal or to incorporate geothermal into their new construction project.

This post is a series of videos describing the process of installing geothermal in a residential new construction project.

Step 1:  Drilling the Wells

The number of wells to be drilled is determined by the heat load of the structure, the nature of the soil on the property and the water table.  This is determined on a case by case basis.

Step 2:  Grouting the Wells

Grout or other cement product is then pumped into the well hole to secure the loop.




Step 3:  Installing the Header for Vertical Ground Loops

The header manifold connects the wells to each other in series and brings the loop into the building.



Step 4:  Installing Ductwork, Piping and Geothermal Heat Pumps.


The ductwork for a geothermal installation is identical to an air cooled system.  The geothermal heat pump uses heat pump technology but instead of using air to transfer heat, it uses water from the well loops.




Step 5: Flushing and Purging

Before the system can be operated, the loop and well system must be flushed of all impurities.  The water in the loop is then treated to prohibit organic growth and chemical scale.


Step 6: Installing the Desuperheater

A desuperheater uses the heat generated in the refrigerant tubing of the Water Source Heat Pump to preheat the hot water of the home, further increasing efficiency.
