Energy Monster performed our MassSave audit, MassSave insulation work (recommended by the audit), and a 10kW Solar installation all within a 3-month time period (Nov 2018-Jan 2019). All three projects went well and we are very happy with the quality of work and all of the employees that we've dealt with. The Solar installation was very well executed with almost no exposed conduit, clean wiring, detailed system monitoring, and more attractive (and efficient) panels. We also had an EV charger installed as part of the package. ... read more

I had light bulbs, thermostats and showerheads updated with energy efficient replacements all got FREE. This equipment would have costed over $700! I also was made aware of zero interest loans to cover heating equipment, windows central air etc. the best part was the insulation consultation. The program through Mass Save is incredible. Mass pays 75% of the cost associated with insulation installa... read more

Had the pleasure of working with energy monster through the mass save program. First off the savings were incredible. First, new lightbulbs throughout the house as well as brand new digital thermostats for no cost. I needed some extra insulation and some other odds and ends done that quoted to $2100, I only had to pay $400. Not only were the savings incredible but the customer service was unmatched. Scheduling the appointments was as easy as a 5 minute phone call and the technicians that came to do the work were great. Let m... read more
