The Energy Monster MA is a Worcester insulation and energy-efficiency company whose written reviews run from 2010 to 2020, nearly all on Angi. It lists insulation of several kinds, spray foam, energy audits and heat pump installation, and describes itself as having over 10 years in the business. The insulation jobs are the heart of it. In a February 2011 review, a homeowner with ice dams said the problem went away after the crew installed air sealing and cellulose, and that the company found utility rebates to help pay for it. A June 2010 reviewer said the insulation went in in one day and the crew cleaned up afterward. In a July 2020 review, a customer said Mike walked them through applying for state heat pump rebates and was reachable by email, and that they hired the company again for solar panels. One account went the other way: in a September 2014 review, a customer said the insulation was fine but the vinyl siding removed to do it was not put back completely or correctly, and scheduling communication was poor. The company's Massachusetts home improvement contractor registration, #176201, is expired on the state registry. Angi and HomeAdvisor each show 4.6 stars from 12 ratings.
These guys were fantastic! Mike really knows his heat pumps and it showsâ he was always available via email when I had a question, he walked us through the entire process for applying for the state heat pump rebates, and we couldnâ t be happier with the system one year in. Because of our Initial positive experience with Mike, we also hired Energy Monster to do our solar panel installation. Top notch, LOCAL company!
Patrick was great came right out to give us a quote. We chose to go with Energy Monster because they were the best quality job for a great price. Patrick answered all my questions and advised me on what would be best for the space. We are planning on using them for our next project.
Fantastic Customer Service would give more stars if I could, everyone from the office staff to the workers are top notch highly recommend and will use them in the future!
Quick to respond, all work finished in a timely manner, reasonable price.
They were good on installing insulation but were terrible in completely and correctly replacing the vinyl siding they removed to do it. There scheduling and communication around scheduling was poor.
