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.
