  Courtney & her team were super professional & efficient, from the Mass Save audit during which Jim pointed out items that had never been mentioned in previous audits to the quick & thorough work that was made of installation of insulation in our attic & weatherproofing all entrances. I would not hesitate to use Energy Monster again & highly recommend them.

  I cannot say enough good things about our experience with Energy Monster! We had a fairly large installation of ductless mini-splits installed, along with removal of the existing system, and everyone involved were very professional and skilled. Not only did they get the job finished when promised, but in fact after I got my heat loan so quickly they moved up the installation by a week. The Mitsubishi AC units have had a good workout with the recent hot weather, and they are working great (and are amazingly quiet). Highly recommended!

  Love the whole team at Energy Monster! Jim did a very thorough Mass Save Audit for us and helped us figure out why our house was so cold in the winter (zero insulation in our 1870s walls!) and helped us set up having Pat and his insulation crew come out to make things right. Everyone was professional, efficient, and kind. The insulation crew finished in half the time I thought they needed, wrapping up early each day and cleaning everything up so there was almost no evidence they had been there! And our house feels warmer and quieter already -- amazing! Also a special thank you to Tawny and Courtney at the office -- they very quickly resent the knob & tube form that my electrician needed to sign when I couldn't find the original PDF in my email. They were professional and helpful when I was panicking. Thank you! I really love working with this company, and I look forward to having them come back to install mini-splits and solar panels! Thanks, Energy Monster. Update as of 6/18/21: We had previously worked with Energy Monster on a Mass Save audit and then having them add insulation to our house. This time, we had the guys from Energy Monster back again to perform an electrical upgrade on our house (100 to 200 amps) and then install five ductless mini-splits for more efficient heating/cooling than our ancient terrible radiators. Despite dealing with a lot of obstacles -- a heat delay due to several 90 degree days and then tons of rain that prevented them from doing the outside work on the days they wanted -- the whole team was professional and efficient and made the most of the time when the weather finally cooperated! (Plus, my dog loved the whole crew and they loved him back.) It has been such a pleasure to work with Energy Monster as we turn our house into the energy efficient home of our dreams. Thank you!! We can't wait for Energy Monster to come back later this summer to install solar panels next!
