“I couldn’t speak more highly of everyone at SIGMA, they are all nice, professional and go the extra mile. As a local business owner, four days with no electricity would be devastating. Jeremy called me, and then showed up at my door the night of the storm to check on my system the other night. The system is awesome, and the service is amazing, and that’s all I could ask for. Everyone I’ve recommended them to has nothing but great things to say. ” -Jack McInnis, Scituate, MA

“Sigma installed central AC in our house this spring. The entire process was handled in a professional manner from the sales (Rich) through the installation and testing. The install crew could not have been friendlier or more professional. They even cleaned up after each installation process and left the house as clean if not cleaner when they were done. The cost was similar to other companies, but the service surpassed all of our expectations. A top notch company!”

“Well I guess I managed to find the best, reliable and efficient service in the South Shore when I happened by chance to have been sent Jeremy from Sigma . I wish to say thank you for the honest work, information and the impression you have made on me.I no longer will have to wear ear plugs to bed now that I have a new circulator. Wow it is so quiet here.I even saw the cat unpack her bags she had ready to move.I really do appreciate your help. I would like to make an appointment with David Tucker to obtain information and a bid for a new heating system. Because this one wishes to pass away slowly. I obtained his name and card from Jeremy who speaks highly of your company and if everyone there is anything like him I will be safe in picking your company to do the work. I valued Jeremy’s work and professional manner. Thank you to him and your company.”
“Dave Tucker and his team have been tremendous. They showed up when they said they would, focused on how to make the process as least disruptive as possible and focused on a quality installation. We did have some issues with old parts of the system we were not replacing but Dave and his team took on those challenges and helped us find ways to remedy and in some cases warranty the changes. I would definitely recommend Sigma and their team.”
