Energy Monster

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!

Energy Monster Installers did a great job: Jose and his brother were my installers and they were super thorough, clean, courteous and all around nice people to deal with. They took the time to answer my questions and reviewed the instructions for the unit. I would not hesitate to use them again or recommend them to others.

Jose did a great job replacing a noisy pump in my attic with a gravity fed system. Everyone in my house would like to thank him. We can now sleep soundly without that pump going off every 15 seconds.. Very quick response and professional service thanks!!!!

The Energy Monster team worked with me to design, acquire and install a duckless mini-split system. All the way through the installation the experience was professional. The system was installed a week early and in less time than planned. A very positive experience. Communication was timely and always followed up on. I look foward to a similar experience processing my rebate. A-PLUS!

Energy Monster "completed" work of my mini-split heat pump system on May 19th. The same day they completed work, the unit (the most expensive unit too) responsible for cooling the dining room and kitchen died. We are still waiting on a replacement unit. We were told time and time again that it would be repaired within a week or so. Mike Heil was the project manager and had zero time for my questions and was rude and abrupt on every phone call.

Courtney, the director of operations, took over as my contact once Mike was, and I quote, "no longer with us". She has been much more kind but the unit is still dead and we do not know when it will be replaced.

My wife is 8 months pregnant. It's about to be a week straight of 90+ temps. The lack of follow through on this is disappointing to say the least.

This wasn’t a great experience.

They broke my vinyl siding and left dirty hand prints all over the side of my house even though I didn’t even want insulation done in the walls. They just rushed ahead without checking. Then they used a literal handful of white sl to sloppily replace the broken piece.

They moved my lawnmower and garden supplies into the yard and left it all outside in the rain — never even returned it when they left. I can’t easily see that portion of my yard so didn’t notice until we’ll after they left.

Used too long screws so that they protruded through the ceiling. This was very obvious but they left it like that anyway, only fixing it once I called and asked.

Installed a bathroom/roof vent incorrectly into my brand new roof causing my ceiling to leak (they did correct this eventually).

I chose them based on good reviews but I was surprised by how shoddy and careless they were which made me concerned about the quality of work done.

Update: Roof has now leaked a second time and they came to fix a second time. Left me having to fix the sloppy joint compound work they did on the ceiling, prime, paint, and reinstall the light fixture all over again. Ceiling all cracked up now. Problem after problem. I don’t trust the work they do at this point.

Besides the competitive cost and professional details provided by their sales team, I’m also pleased by after sale service from Kyle. They are patient and take care of their customer to address any concerns. I would recommend Energy Monster at Worcester for anyone looking to install solar system.

I can't say enough good things about this company! They took care of heat pump installation so fast, and the first year I've used the heat pumps I've already saved money! When I had an issue they were prompt and resolved it immediately. The installation team is professional and courteous. very nice , knowledgeable young men. Jose was a superstar.

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.
