    We just had a superior experience with Bergeron Mechanical systems. The installation team was exceptional - both professionally and personally. A specific “thank you” to Eric LaLiberte, John Cartland, Jason Cunningham, Geoffrey Murray and Peter Speckman from Susie and Tom Johnston

    From start to finish, Bergeron mechanical was a pleasure to work with. I had 2 Mitsubishi split air conditioners installed in my home. The installation team -John Carland, Geoffrey Murray, Landon Wilks, Jason Cunningham & Landon Hammer were incredibly respectful, knowledgeable, & professional. I would highly recommend their services and this team of professionals to anyone looking to purchase a/c splits.

    Great company and service. Had 2 compressors and 4 mini splits installed and these guys are pros. On-time (they even text and email you when they are on their way and when they arrive) and clean. Geoff, Jason, Adam, John and Landon were all awesome. I'd hire these guys again for my next project.
