"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"David Sampaio from SumZero was one of six contractors we interviewed for central AC replacement. David was very helpful in our decision making process when we were deciding between AC and heat pump units. His price was very reasonable too. We chose the heat pump in the end and are very happy with the choice. David’s team was very polite and professional during installation, they did an excellent job setting everything up and cleaning the area. High five, David! Thank you!"

"Metro West Mini Splits recently installed 6 mini splits in February 2025 to our new home in Marlborough, MA. Alan, Jamie, and their team were so kind, respectful, knowledgeable, timely, communicative, and easy to work with. We could not be happier with the final product! Metro West Mini Splits was also very reasonably priced, and they made the Mass Save rebate process a breeze. 100% would recommend to anyone needing heating or cooling services!"
