Why Geo Final

This team specializes in service, installation, and “rescue” of the more advanced HVAC systems on the Vineyard.  At the head of this department is Brian Nelson,  who established NMD with his business partner Dave Sprague in 2004.

Since then, Brian has supervised the “rescue” of over a dozen intricate HVAC systems that were underperforming, inefficient, or constantly trouble-prone.  Using his engineering background (M.S.M.E. from Boston University) to address design issues and his Master Plumbing license for installation issues, Brian and his team can analyze and resolve a wide array of system issues.

This team is also skilled at the installation of geothermal, radiant, and advanced hydronic systems including solar hot water heating, air to water heat pumps, geothermal heat pumps, and condensing boilers.

Geothermal - Radiant - Rescue Team Pictures

  • Geothermal "Rescue" - hiding a 40 ton fluid cooler behind a stone wall to increase cooling capacity to a geothermal system.

  • This radiant system has 17 zones featuring all copper tubing in the floor using copper heat transfer plates - heated by two air to water heat pumps.

  • This geothermal installation was for the first LEED for Homes project on the Vineyard.

  • This solar hot water installation is to our knowledge the largest on the Vineyard.

  • The Air Conditioning "Rescue" at the Norton house restored summer comfort and reliability to the cooling system.

  • Geothermal "Rescue" - changes in the aquifer meant acidic water was dissolving equipment - we installed a plate and frame heat exchanger to restore operation.
