Dave was really knowledgeable and kind. He walked me through the different options. They were able to come to the house same day in Somerville and fix our issues.

Dave came to inspect our malfunctioning AC and was great! He was so friendly, generous with his time and information, explained how the system should work and what maintenance should look like, and checked multiple times to see if I had questions. I would definitely work with him again.

Great tech helped me cap a gas line to my dryer, had to access the wall so he cut a hole. Ran me 600 which is a lot but I understand these types of things are expensive.

Amelia Whitaker8 reviewsiTotal number of Google reviews Amelia has written across all businesses on Google Maps, not just this one.
I contacted Green Tech because the boiler and 3 mini split units in my recently purchased home in Somerville were overdue for maintenance. They got back to me promptly and were able to come the next day. Dave arrived right at the beginning of the arrival window and was very diligent, thorough, and careful with my belongs, etc. He was also friendly and professional and communicated clearly about the processes and pricing. The mini splits are working much more efficiently now, without dripping, and most importantly without all the black mold that he discovered.
