What Clients Say

“Energy Monster was recommended by a good friend and I can’t say enough good things. From my initial call, the level of Customer Service was top-notch. Every step of our home energy assessment was thoroughly explained and a detailed, easy to read quote was provided for exactly what we had requested with no pressure of adding on services that were suggested. The work that was performed was done in a clean, professional manner and again, everything was thoroughly explained. If you’re looking to improve the energy efficiency of your home, I highly recommend Energy Monster and will be using them in the future as we continue to upgrade our homes energy consumption.”

Chris B – Princeton, MA

“Mike Heil was very professional, knowledge and provided exceptional service. Anyone who owns a home should get in on this program. 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 installation.

Overall very impressed!”

Kim- Douglas, MA

“Tired of getting gouged by ever-inflating electricity and propane prices, we decided to go solar and chose EnergyMonster as our partner.
I won’t ding EM on a star for this but we were a bit disheartened when the installation didn’t begin until months after the contract was signed so we missed out on a summer’s worth of solar production. In every other regard, however, EnergyMonster didn’t disappoint.
The engineer on our project was very insightful, tech savvy, and up-to-date on all things solar. He was also involved in the sales process which was valuable to both myself and EM.
Typical Solar companies lack in this regard as they just send out pitch-men with a script. Dan G. is at top of the top of his class and was able to address each and every concern.
A team of just two, very hardworking, individuals performed the 38-panel installation in a little over a week. They were very kind, courteous, and worked around our schedule.
The electrical work was phenomena: extremely clean, organized, and tightly-knit.
Overall, the EnergyMonster team is comprised of down-to-earth people which is very refreshing these days. Additionally, EM provides the latest and greatest technology which others do not (despite what they may pitch to you).
I would highly recommend over competing companies such as Tesla/Solar City (the Wal-Mart of Solar) as these guys truly know their stuff and remain passionate.”

Jeff S- Dedham, MA

“We recently had Energy Monster install solar panels on our house in Needham. Everything went well and our electric meter is happily running backwards.

I started out knowing little about solar power. I got quotes from several suppliers and went through various design iterations. Dan answered my questions and concerns promptly and we settled on a practical and cost-effective solution. When Chris came out for the site survey he added to my confidence that I had made the right choice. He and Brandon did a very professional, efficient and clean installation. Finally, Dan came to the house for the “commissioning” and to show me the cool software that lets me monitor my system’s performance from anywhere in the world. He flew the company drone to take “sun’s-eye” views of the finished product.

With Energy Monster I made the right choice financially, technically and practically. I highly recommend them to anyone considering a solar power system”

Noel P- Needham, MA

“We had an excellent experience with Energy Monster with our recent residential solar installation from start to finish. The process was made simple from initial conversation with Orlando, followed by detailed step-by-step technical guidance from Dan and smooth installation by Chris. They took care of all pre-project tasks like approvals & inspections and handled all post-project tasks like integration with electrical distributor & production monitoring system. Dan was very responsive throughout the process. I would highly recommend Energy Monster”

Viper- Acton, MA

“We had Energy Monster install 124 panels on my new shop. The process was easy and on schedule. I was in touch with Dan the entire time and he walked me through all of the paperwork that needed to be completed, showed me the designs as they were completed and kept me informed the entire time. I have recommended them to all of our surrounding neighbors. So far the system has saved me an estimated $5000 in electricity costs. I cannot be happier. Thank you Energy Monster!”

Sarah McCauley- Easton, MA

“Energy Monster’s Project Manager, Design Engineer, Sells rep and field technicians were all very knowledgeable, took their to come up with the most efficient and affordable method to save energy at my property. The team did not measure any efforts in every detail of my project.
Additionally, the Project Manager accepted that their bid for the project was not the only one; he was able to counter-offer all other bidders, offering a better price.
Finally, I was confident that Energy Monster was the right contractor for this project, considering their determination, and warmth passed along.
I would recommend and will definitely hire their services again once needed”

Marcelo Peres- East Bridgewater, MA

“Choosing Energy Monster for my solar project has had to be the easiest choice I’ve ever made hands down! Dan was awesome and knowledgeable. Not only did they have the best quote but they also were very professional and easy to work with throughout the whole process. Now let me tell you when they came to install and they told me they were finished I didn’t believe them, I had to run outside and see for myself. They did their work fast, quiet, and kept my house clean what more can you ask for. This company has got to be one of the best out there and should be your go to. Thanks for everything!”

Dat Nguyen- Springfield, MA

“I installed a 9kw solar panel this summer in my Franklin, MA home. Dan was great in streamlining the installation and was there whenever I needed information from regarding the Solar loan. Chris, the lead engineer who did the installation is also a great person who will take the time to explain everything to you if asked. My production has been close to what was estimated, even with the extremely rainy season we’ve just had. All in all, I’d recommend Energy Monster to my friends.They are a great local company who will give you the attention deserved; Single handedly beats the ‘big guys'”

Fahad- Franklin MA

After installing solar panels, one month my electric bill was -$8.00. Things are working out great.

[I] just wanted you to know what fine representatives of your business worked at my home today. The entire crew was knowledgeable about the product and very professional in the work they did.

I wanted to thank you for the coordination and the completion of the work order for my house insulation. The team presented themselves today at my house on time, they explained me the process thoroughly step by step. Changes made to the work order were discussed and agreed together after the teams inspection. All the work was done professionally and after it was completed, the team cleaned up all. The team members showed good communication skills and technical knowledge. Thank you all!

Jayne Eringi

Julie was outstanding! She was knowledgeable, informative and pleasant. We highly recommend your company and Julie. We first learned about EM at the Worcester Home Show where we were impressed with Christie and the other lovely employees. We have already recommended EM to our son and other homeowner friends! Thank you!

Peter & Karen McDermott

The crew from Energy Monster was very friendly and professional. They arrived on time & completed the installation ahead of schedule. I would highly recommend Energy Monster to anyone interested in a home efficiency project.

Michael Checkman, Charlestown MA

As the Director of Planning in Andover, MA, I’m involved in numerous green initiatives. There is no better time than the present to perform a home energy efficiency project. There are many rebates available and it’s a project that actually pays you back over time. The folks at Energy Monster performed my Free Home Energy Assessment, communicated openly and did an excellent job on the installation. I’m a fan!

Paul Materazzo, Winchester MA

Becoming more energy efficient in today’s world is becoming increasingly important on numerous levels. I was very impressed with the unprecedented breadth of home efficiency knowledge and workmanship that the team at the Energy Monster brought to my project.

Joffrey Smith, Worcester MA

Having worked with a different home efficiency company on another property in the past; the overall level of quality, performance and professionalism was second to none at Energy Monster. I was also pleased to hear the quality inspector from Mass Save compliment them during the final inspection. I will certainly recommend Energy Monster to my friends and family.

Bob Lebrun, Waltham MA

My interactions with Energy Monster have been excellent. They helped me clearly understand what a Home Energy Assessment entails in addition to the benefits. I had my attic air sealed and insulated. I instantly noticed a difference as my home wasn’t as hot as the day before and it was still 95 degrees outside. I was able to turn down my a/c which will save me on my electric bill. I can’t wait to save on my oil bills this winter! They were also able to get me an instant rebate of 75% off on my project…who even knew they could do that!
