  • At FBN we believe that first and foremost we are a “customer service organization.” Our growth and success have been through surrounding ourselves with like-minded people and companies that believe that as well. Lavallee Systems has supported and enriched that approach through their timely response and excellent service over the years, and we would recommend them highly. They “get it” and are a great partner with us in caring for our clients’ homes.

  • Having worked closely with Jim and Lavallee Systems for the last 5 years on many projects, including a couple that were exceedingly complex, I can honestly say that their focus on technical knowledge and customer service coupled with their "can do" approach, make them a welcome collaborator for Adams + Beasley.  Every project encounters unforeseen obstacles, in-process curveballs, and client requests that challenge the team.  Lavallee Systems employs an approach to quickly propose solutions, help the team adjust their sails, and keep the project on track.  We are grateful for our ongoing relationship."

  • As Architects, we truly appreciate HVAC Contractors who can work collaboratively with us to achieve a house that performs as beautifully as it looks.  Jim and his team are a dream to work with.  We recommend them without reservation for their in-depth knowledge of systems old and new, their thoughtful problem-solving skills, and their friendly and reliable service.

  • I have had the pleasure of working with Lavallee Systems on several occasions where they installed HVAC systems designed by us at SUN Engineering, Inc. We design only high-end HVAC systems for the most discriminating architects, homeowners, and builders in the Boston area. The projects on Commonwealth Ave and at Rowe’s Wharf in Boston were very challenging with little room for HVAC modern systems, and they performed flawlessly.

    Their workmanship was impeccable, the site coordination and professionalism second to none and we will continue to suggest them for high end residences in the future.

  • We have had nothing but excellent experiences with Jim Lavallee and his team of expert plumbing and HVAC specialists. They are creative problem-solvers, professionally astute, and accommodating. They listen, offer cogent explanations of equipment and methodologies, and look for solutions that integrate with the architecture and design intent of our projects. Not only have they been a vital part of our architecture and construction teams, but we readily recommend them when clients or past clients need help. It is a pleasure to be able to pass their name on to people we care about.

  • Lavallee Systems has become our go-to HVAC subcontractor. Their long experience in the industry and their commitment to staying ahead of the curve has proven invaluable, particularly as we have transitioned more and more to heat pump technology. They are courteous and professional, and they always stand behind their work. We couldn’t ask for a better partner for our remodeling projects.
