Complicated Systems Made Simple, Since 1995
Comfort Shouldn't be Seen, or Heard.

We specialize in designing heating, ventilating and cooling systems for clients with challenging architectural designs, and we think you'll appreciate what we can bring to your next HVAC challenge.

Many of our homes we have designed heating and cooling systems for are in Architectural Digest, high end home magazines and have won awards for LEED standards and historical significance.

We specialize in designing state of the art heating and cooling systems for high end homes on Beacon Hill, Back Bay, Cambridge, the western suburbs, Cape Cod, Nantucket and Marthas Vineyard, the lakes of New Hampshire, Vermont and Rhode Island. We understand a families home no matter how large is still a living room, a master bedroom, a quiet retreat and we understand how to design systems that will keep you comfortable year round.

Many of our designs incorporate the latest in:

  • Geothermal heating and cooling systems 
  • Solar PV and solar thermal systems 
  • The latest in sound and vibration technology to create quiet systems
  • High efficiency gas and oil heating systems
  • Indoor pool heating and dehumidifying systems
  • High end kitchen ventilation and make up air systems
  • Nortec clean steam humidifiers
  • High efficiency air filters
  • Air-to-air heat exchangers
  • Wine cellar systems

At Sun Engineering, our systems are designed to complement, not interfere.


ERV - Energy Recovery Ventilator
This device is similar to an HRV except it also recovers the moisture in winter that would ordinarily be lost to the outside. In summer, it brings in fresh air while rejecting the excess moisture to the outside. This allows your central a/c system to work easier by not having to dehumidify the hot humid air being introduced by the ventilator.
