We had previously worked with Energy Monster on a Mass Save audit and then adding 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 the 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!

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.

I evaluated quotes from three PV companies before I placed an order for a 24-panel system. Here are three reasons why I went with Energy Monster: 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 and 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.

The owner will do NOTHING to fix our non working air conditioner. As soon as the temp goes over 90 degrees—it stops working. When my husband was trying to have a conversation with the owner today, he hung up on him. Unbelievable!! Boy, did we get screwed! We paid this company almost $20,000 less than a year ago to install a new system. Your customers need to beware of Energy Monster being absolute CROOKS and DO NOT USE this company! Now we have to use a portable aircondtioner in our bedroom to stay barely cool when temp rises over 90.

My experience was wonderful. The staff is extremely knowledgeable and after a thorough assessment, they were able to insulate my attic as well as create a dome over my attic entrance for the drafts. It has made all the difference! On top of that, they were able to recommend several other options and items that are covered through the Mass Save program to improve my energy savings. They will assist in any way they can and make sure you understand what's happening every step of the way.

The auditor that came out made the whole process so easy and understandable. He changed my light bulbs and a few other little things but i have already seen a huge difference on my electric bill just from the lighting. I learned a lot about my house and how it works as a system so that was cool too! I had insulation work done a few weeks after my audit and it has made my home and bills so much more comfortable and affordable. THE BEST PART IS I PAID A FRACTION OF WHAT THE JOB ACTUALLY COST for the insulation and NOTHING for the lights. I can't believe i didn't do this sooner. If you are looking for a professional, Courteous, and Reliable contractor then look no further!

Energy monster is the best company I have dealt with in a long time, shamus and his crew were great and very polite, professional, and the cleaned and vacuumed up everything before they left,. It was like I had no work done after they left they were that great. Even the girl on the phone that set up everything was very pleasant,I would hire and recommend them very highly to everyone. Thank you for the best experience,

The service was free. The quality was good. Punctuality was pretty good. They were basically checking up on things. They were a little bit unresponsive when we were in the house until we knew exactly what they were doing and checking up on. It wasn't a major issue.

The workers were on time, polite, and dedicated to their job, but I wish I would have supervised the job.  I was not told to wear a mask, nor to leave the house during the job.  Cellulose dust got everywhere as they did not block off the area they were working in from the rest of the house.   I actually experienced respiratory challenges for a several days after and had to call a professional cleaner to come in with HEPA gear to deep clean the house.

We never heard back with a report from Miguel or anyone from Energy Monster & several weeks passed before we finally checked back in to see what was up?  We needed that report to file with National Grid so we could submit an application to MassSave to see if we could qualify for a loan to have a new furnace/boiler & indirect water heater system installed.  Our current system was running below standard & we were having yearly problems with it & zones freezing up with no heat.  We learned (then) that Miguel left the company & never turned in OUR report OR any of the photos he took throughout our home & no one at Energy Monster had the courtesy to call us to let us know any of this!   We let them know how upset & very disappointed we were with their lack of follow-up or professionalism.  They handed our case over to their supervisor, Julie Pennett who assured us she would be out to make things right.
Julie did finally come out & spent several hours (re-doing) the entire inspection...taking more pictures, measurements, etc. etc.  After all of that...she assured us ...we would receive a (thorough report & RECOMMENDATIONS most importantly) as to what we should take care to improve our current energy problems & make sure we received this report to submit to National Grid for our MassSave application.  Julie also asked if we'd like (their new team of furnace/water heater installers) to come out & assess our current system & give us a quote.  These 2 guys came out & were very courteous & seemed to have a reasonable knowledge & gave a reasonable quote for a new heating system (which followed in the mail).  However, we received (just the bare necessity energy report) from Julie to submit so we could send in our application to apply for our MassSave loan.  We called & asked when we'd receive the {full report of recommendations} and NEVER received that report after we were assured a 2nd time that we would be receiving it in the mail.
Energy Monster just seemed to have some (internal management problems) and were JUST getting a (new) HVAC team on board & in place.  They just didn't seem to have all their ducks in a row there & there was a definite break down in communication along the way.  In the end, we were not impressed with their service & would (not) give them a great recommendation or high rating.

AMAZING! Our auditor was prompt and courteous. My husband and I felt extremely well-taken care of.  In addition to his professionalism about our home insulation and energy efficiency, we also received tips, strategies and suggestions on how to help heat our home efficiently and effectively, beyond just the work that Energy Monster can perform on my house. The auditor was incredibly knowledgeable - clearly an expert. We also appreciated his interest in the environmentally-friendly aspect of the business, as well as saving us money on our utilities bill. A free home audit, knowledgeable and personable staff - I HIGHLY recommend this company!!!!

Our auditor was very enthusiastic about helping us save on our energy costs. He was patient with my husband we discussed our unhappiness with our heating bill and the drafts in our home. We also got some some free lightbulbs and a showerhead replacement! We didn't feel any pressure to get any work done but after talking to our auditor we moved forward with getting some air sealing and insulation work done. 
The crew was great - very respectful and timely. I was concerned about the mess that might be left afterwards but the guys cleaned up great!

I had Energy Monster complete an energy efficiency evaluation at my house through the Mass Save program.  The two evaluators were on time and went through my house conducting their evaluation.  They also asked if I had any areas that I knew needed improvement, (my attic insulation).  They were thorough in explaining the evaluation and what areas could be improved upon.  They didn't pressure me to complete any work nor did they pressure me to use their company.  
I ended up using Energy Monster to add insulation under the Mass Save program, it only cost $330 by doing so.  The crew was on time, professional, and explained the work they would be doing.  They were there for about five hours and cleaned up after themselves.  I would use them again and have recommended them twice to friends looking to have insulation added.

I thought my home energy audit
with energy monster went great.  Their home energy advisor was
?Jim?.  He showed up on time, was informative and helped me learn a lot
about how they can help my home be more energy efficient.
I agreed to have the recommended measures done and signed the contract that
day.  I received a call to schedule the work within a week by a nice lady
who was very pleasant.  On the day of the work everyone was very nice,
clean and professional and the job went smoothly which is rare from what I?ve
read about the trade which is why I chose Energy Monster in the first place
with their great reviews. The guys seemed very respectful and appeared to care
about doing a good job.  The manager (I forget his name ? sorry) even
stopped by to check on things during the work and introduced himself.
My energy bills are already
noticeably lower!   I would highly recommend Energy Monster and
will.
