The HVAC department at NMD is well versed in the installation of Geothermal heating and cooling systems in residential new construction and remodel projects for the homeowner and contractor.

Our experience with several Geothermal and heat loss design software suites permits us to accurately design a Geothermal system to meet your building’s heating and cooling loads.  This ensures correct operation of the system throughout the year.

We are also able to assist homeowners and contractors through our in-depth experience and expertise in the coordination between trades (well drillers, excavation contractors, plumbing, electrical, etc.)  to make sure the Geothermal installation is successful.

Contact Dave Sprague, head of our HVAC department, to discuss your Geothermal installation project and see how NMD can assist in the process.

If your geothermal system has performance issues, please see information about our Rescue Process.
