Frequently Asked Questions:
The menu topics are representative of questions we have answered about the equipment and systems we install and service.   While the laws of physics haven’t changed lately, technology is evolving constantly, and our role at NMD is to understand how this evolution affects our systems and customers.  We are constantly learning about new techniques and approaches to HVAC and plumbing systems so that we can provide intelligent responses to your queries.

About Your System:
Each of these menu topics describe the components of  the various heating, cooling, ventilation, and plumbing systems that we install and service.  Our goal is to make this part of our website a resource to better inform our customers about their equipment and systems.  When you call for service, we hope the information will assist you in describing what kind of service you need.  When you receive an invoice from us, we hope the information will help clarify which parts and systems we worked on during our service visit.

Our role is to install and service the most reliable and modern heating, cooling, ventilation, air quality, plumbing, and water treatment equipment available.  We serve as an essential filter for our customers – determining what innovations are worth pursuing and what new products we can stand behind.  This requires a constant commitment to training the NMD team so that we know how to service what we install.

Our goal is to be Martha’s Vineyard’s premier plumbing and HVAC shop – we appreciate the opportunity to service and install your plumbing and HVAC system!
