What Clients Say

“Dealing with EnergyMonster is one of those things you will look back on and think to yourself “wow that was way easier than I anticipated, we should’ve done that years ago!” Courtney and the rest of the team are some of the most professional people I have ever had the pleasure of doing business with. I send friends, family and clients to Courtney every opportunity I get!”

“My wife and I had our solar system installed by Energy Monster just about one year ago. The staff at EM were very thorough, answered all of questions, and fully explained the system they thought would be best for us. Once the system was installed, it was turned on July 1st, so we had July, August and September, of extended daylight, which provided us with great production. Fall and winter, with shorter sunlight, obviously not as productive. As of our first spring with solar, March, April, May and June we have produced more than the first 6 months of having the system. We have accumulated a substantial credit with National Grid which will offset the most if not all electric usage in the fall and winter months. We are very pleased with system, all that the Energy Monster Team has provided us.”

“Kevin was great to work with. Their product offerings were exactly what we needed, really like the Critter Guard we wrapped the system with. Everything was installed smoothly, great crews.”

“It was a great experience working with the team at Energy Monster to install a roof mounted solar array. After getting proposals from several companies, we chose Energy Monster for a few reasons: positive reviews from other customers, good impression from their sales rep, strong project proposal including equipment and warranties, good price and value. From start to finish the project did take longer than anticipated. But this was mainly due to the fact that we had other projects going on simultaneously as part of the overall solar package. We had trees removed, a new roof put on, and the electrical service upgraded to 200A before the solar installation could happen. Energy Monster did the service upgrade themselves and was supportive while I scheduled the other jobs. Not to mention this was all going on during the middle of a pandemic. Not long after the system was installed and the electric utility company approved it and switched it on, there developed a problem with one of the panels and one of the microinverters. Energy Monster was quick to send someone out to investigate and replace the parts under warranty at no cost and no hassle. It’s been almost a year now, and I’m happy to report that the system is operating very well. We’re actually projected to surpass our energy production goal. I usually check the solar reporting app everyday to see how well the system is performing and how much power we’re making. I’d recommend solar to everyone, and would recommend going with Energy Monster.”

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.

Professional service from start to finish

I spent many hours researching local solar companies and went through an hour long presentation with another company to gain knowledge about solar power. After getting quotes from several companies and comparing apples with apples, Energy Monster was by far the most professional looking presentation. From there it only got better. Communication was excellent, especially Kyle Johnson, who replied to phone and emails very quickly. Questions and concerns were always responded to. Installation was done without much interference with our new-normal lives. Final inspection and meter installation was completed without any hiccups!

Best Investment Ever

While working with Kevin Markey and Daniel Gawrych from Energy Monster was an excellent experience, I wanted to wait a year before writing a review because I wanted to see what the one year “return” would be. It has been better than we could have ever imagined. We have not paid $0.01 for electricity during the past 13 months. Even though there is a monthly payment due each month for the purchase of the panels, the savings from not paying ANYTHING to National Grid, the money we get back each month from the Mass Saves program, the credit that we have built up with National Grid, and the savings we have in our natural gas bill (we installed a heat pump that was almost free after Mass Save rebates to offset heating and cooling costs) are more then the cost of the panels. We would do this again if we move and we would use Energy Monster to do it.

The work at my home is completed and I just wanted to tell you how delighted we all are with the results! This project has made that little house a nice tight and comfortable home and it really needed that. We”ll remember that every very hot or very cold day or night. All of your crews were very professional and did their work in a timely manner and cleaned up after themselves, especially the insulation team. I would not want to have had to go into those spaces but hey did so in a very efficient manner The mini-split AC guys were equally professional and neat. I had the opportunity to go over while they were installing and they were very courteous and explained everything to me and I can tell they really know their “stuff.” You are very fortunate to have such a great staff as they they are the face that the public and client really remember. Lastly, Michael Heil was definitely key and getting all of this done even with the interruption of the pandemic. I was very impressed with his knowledge and organizational skills. Thanks Michael! Thanks again to all for the great job!

I looked at several different companies before choosing Energy Monster. The sales process was very professional and they offered by far the best value. The value was so much better that I was actually a little worried that the deal was “too good to be true.” But they absolutely delivered on their promises through the install and operations. Great company and I highly recommend them!

Very Happy with my Solar

I have 33 350 watt panels now on the roof, The process was very smooth and the correspondence back and forth has been better than with other companies I tried to work with. They gave me exactly what I wanted and for less than other companies. The week before I had installed new hard wood floors, The electricians that needed to get into the attic took of their shoes when working – Nice Guys The array looks great on the roof and I’m on my way to being electric independent

Terrific Value!

Everyone starting with Orlando Rodriguez the initial salesman, to Kyle Johnson my program manager to the installation crew, to the electricians were extremely professional, responsive and quality oriented. I loved the fact that there is a 20 year, transferable warranty and they will stay involved the whole time. They helped me get the rebates and made the system very affordable. 5 stars is well deserved!

Just had a big crew out to air seal, and insulate my attic and garage. It was a ton of work and they did a great job. Cleanup was thorough and they showed me what they were doing as they went along. Their auditor listened to what I was looking for and made solid suggestions on what work was best for my home. Highly recommended

Thank you Energy Monster! Your company has a staff that is prompt, courteous and very easy to deal with. We appreciate dealing with people who are quick to respond to questions and make every effort to serve their customers. Estimates, communications and installation were all handled professionally-very nice work.

“EnergyMonster sent Jim out to my house for an energy assessment. I figured it’d be a quick look in the attic and at the bulbs. Jim proved me wrong on that one. He inspected almost every inch of my house looking for potential areas of improvement. His expertise with working in homes actually led him to telling me a few extra things about my house that I wasn’t aware of. Super helpful, almost more so than the professional inspector we hired. I’m happy I went with EnergyMonster and lucky to have had Jim as my advisor.”

Hi, I used Energy Monster to install 3 ductless mini-splits in my house. The installation was done quickly and efficiently, the installation team was knowledgable and friendly, and they worked hard to ensure I got the rebate for the installation. They also did a free energy audit that was very helpful. I would recommend Energy Monster to anyone looking to make their house more energy efficient.

From beginning to end the company was great. No high pressure sales pitch and price was way better than others for equal or better equipment. Every step of way workings were very quick to answer any questions and made process very simple. I’d highly recommend this company. Great customer Service!

Professional and timeline was accurate. They quoted me for the most panels to handle my present and future needs and it wasn’t much more expensive. All other companies quoted me on 8 to 14 panels less with comparable prices!

Energy monster comes very highly recommended by The Remillard family! Mike was extremely helpful and the workers who came to do the install were super professional and polite! This review is long over due but we are VERY happy with our systems! Every bit of this process was made easier by the professionalism and friendly manner of the Energy monster staff.

They did a fantastic job re-insulating our attic and basement. They worked around our hectic schedule, which was appreciated. They were also here right on time and absolutely crushed the project. I really appreciate that they covered our floors and spent a good amount of time making sure everything was cleaned up before they left. We’ve had a ton of work done on our home and this crew was by far one of the best we’ve dealt with. Thanks Angel Machado and crew!

We were extremely selective when we chose our solar installer and products and we chose Energy Monster. Their attention to detail, incredible communication, quality/fit/finish and aesthetically pleasing installation was second to none, and the cost was the best. I don’t do 5 start ratings, but these guys earned every star!

“I’ve waited a couple days since the total service has been completed to leave a review which will have a true impact for Energy Monster. This is intended to give any consumer who looks at their page a honest expectation of their customer service and scope of work. I obviously wanted to see the results first and if any problems rised after service was completed. I had the pleasure of working with Mike Heil, and Mike Weytenus. From the start of our energy audit, planning for ductless mini splits and insulation these 2 guys were always there to answer my call, text or email.
My wife and I are first time home owners. We aren’t well educated on fixing things in our home, as it is a learning process. Mike & Mike made this process less stressful, and also helped us learn. Mike W came by so much my toddler knew him by name and became uncle Mike. This is important when you make a investment in your home. One needs to be able to trust the company you are going to do business with, Energy Monster is that company. Nick, Jose and John from the mini split team were professional, helpful and did a great job. After they completed there were minor issues with factory settings they had to adjust. Without hesitation they came out, fixed the problem, and updated me. The insulation team was friendly, worked quick and treated my home as their own. The difference today, is unbelievable. The home has change so much since all the work has been completed, and my wife and I are very happy.
I believe it’s important for business and consumers to work together, and if a service was done well then one should pay it forward. This is why this review is so lengthy. I know I’ve personally promoted Energy Monster to my friends and family in my community of North Attleboro, on Facebook and word of mouth. As someone who is in the service industry, and covers a large territory I hope many of my friends and family, customers reach out. If your reading this now I encourage you to do business with Energy Monster.”

“I can’t praise this company enough. We got in touch with energy monster via masssave. They did a very professional assessment about a month ago also replacing all light bulbs (even hard to reach ones). Today was my insulation and sealant installation and we discovered what we thought was our brand new roof leaking in one room of the house yesterday. I gave the heads up to energy monster and they still came today to take a look at that room and complete the rest of the house. They did an excellent job with everything and were super professional. Not only did they complete their job, they also identified that the leak we had was not a roof leak, but a burst pipe. We have a plumber on the way, instead of waiting for our roofing contractor to be able to find time to come back in a couple weeks. Thank you Energy Monster you have a great crew!”

“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 me know and understand all the work being performed, very kind an easy going and when they left there was no trace they were there. Very clean, very professional, and very quick. I would recommend to anyone of my friends.”

“I evaluated quotes from three PV companies before I placed an order for a 24-panel PV system with Energy Monster. Here are the three reasons: The publicly traded company that I favored first wanted me to sign away my consumer rights, (1) with no such provisions in Energy Monster’s contract, (2) a good price and (3) Dan G., the very knowledgeable and dedicated sales manager / project manager / system engineer as the main contact, I felt safe placing my order with Energy Monster.

During installation a few obstacles had to be overcome, all of which were related to the town’s permitting process and required licenses. All that got resolved without incident eventually. The installation crew Chris B. (Master Electrician) and Brandon T. did an outstanding job installing the solar system. It passed all inspections with flying colors. There were no start-up problems.

In summary: Energy Monster’s pricing was good, they selected first tier 1 solar panels and inverters, work dedication, workmanship, project management and technical expertise were outstanding. I like that no electric cables are visible. Energy Monster used a roof penetrating feedthrough, which is located underneath the panels. It was tested thoroughly during the torrential rainstorms in the months following the installation. Not a single drop of water was leaking through.

Since August 1, 2018 my PV system produces energy. During the 5 months till the end of the year I harvested 2,936 kWh. I live in Milford, NH. I have 24 LG 320Watt NeON2 panels with Enphase micro inverters. I am very happy with the solar system!”

“I rarely give 5 star reviews but the sales staff, contractors and engineers at Energy Monster have earned that and more. We recently purchased a solar panel system from Energy Monster for our residence. During the entire process we found everyone to be professional, responsive and most importantly deliver on their promises.
We are very pleased with the outcome of our installation and have seen the results of our investment not only in our energy bills, but also the energy credits and refunds from the government. Naturally, like most people we were a little skeptical with this venture in the beginning as it is seldom that consumers actually receive what was promised at the time of the sale. That was not the case with Energy Monster.
We would most heartily endorse and recommend to anyone the services provided by Energy Monster and welcome the opportunity to be used as a reference. We continue to display our “We are saving on our Energy bills” sign on our lawn and will do so until the weather takes it away.
Thank you all!
Sincerely, the proud owners of an Energy Monster system”

“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.”

“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!”

“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.”

“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”

“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”

“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!”

“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”

“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!”

“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'”

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!

I had insulation work on my home today and the crew did an outstanding job! They were extremely polite and courteous. Thank you, I’m very happy with the work you did!

They explained everything thoroughly and even helped me with the paperwork. I am 100% pleased.

Everything went smoothly and on time. I had a schedule…no complaints!

Julie is a very professional, knowledgeable, pleasant person. She answered all our questions, and explained the reasons why. We will definitely recommend this to our friends. We are extremely happy with the service Julie provided.

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!

This is an excellent service and our auditor Julie is terrific. She is highly knowledgeable, very professional, delightful and obviously an expert in this field . Thank you Energy Monster!

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.

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!

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.

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.

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!
