The Energy Monster, Inc.

The company homeowners know as The Energy Monster now answers to a different name. Its site trades as Wattson Home Solutions, run out of Auburn under new owners Heather Cassani and Patrick Burke, doing the work it says it has done since 2008: no-cost Mass Save energy assessments, insulation, spray foam, air sealing, and ductless mini splits. The reviews behind the old name are uniformly good and uniformly old — six ratings averaging 5.0, mirrored across Angi and HomeAdvisor, running from 2012 to 2017. The most useful is from July 2016. A homeowner with fiberglass insulation sagging under a crawlspace wrote that the company evaluated the space, explained Mass Save, recommended a different approach than the one she had called about, then installed fiberglass and foam board and sealed the edges. A January 2016 customer described the part that separates energy work from guesswork: the house was tested before the job, tested again afterwards, and the results shown both times. The freshest word comes from a 2023 r/massachusetts thread, where someone said they had worked with EnergyMonster and that the crew also fixed a bathroom fan that had been venting into the soffit rather than up through the roof. Licensing is where to slow down. BuildZoom lists a general contractor licence, #587, with an expiration date of 07-31-2025; a Home Improvement Contractor registration, #176201, marked inactive; and an inactive Electrical Business licence — and says it could not verify any active licence, which is why the company's BuildZoom score sits at 0. None of those numbers was confirmed against a state registry here. Permit volume points the same way: 171 permits all told, but 28 projects in 2023, 6 in 2024 and 3 in 2025. Both the Angi and HomeAdvisor pages currently carry a "this pro is under review" flag. None of that is a verdict on the workmanship — every written account of an actual installation is positive, and Mass Save weatherization runs through the program's own assessment and inspection process. It does mean the paperwork is worth checking yourself. Ask for the current Home Improvement Contractor registration under the Wattson Home Solutions name, look it up on the state's Consumer Affairs registry, and get the rebate and financing path in writing before anyone opens a wall. A reasonable call for a Mass Save assessment plus insulation and air sealing around Worcester, particularly if a mini split is part of the plan — once the registration question is settled.
