Heat Huggers Insulation LLC

Heat Huggers Insulation works mostly through the Massachusetts Mass Save program, helping homeowners get attic insulation and air-sealing done, and the record here splits sharply in two: happy customers who got exactly that, and at least one customer who says the crew never showed up. On the positive side, a 2025 review described a Mass Save attic insulation job that had a couple of minor issues along the way, resolved by the crew before the reviewer would recommend them. Two 2024 Angi reviews praised a crew that was timely, professional, and respectful of the home throughout the job, and a 2023 review thanked two named crew members for their work in Whitman. The record isn't all like that. In a December 2025 review, a homeowner described the crew missing two confirmed appointments for a three-day job, citing a truck problem the first day, then never calling back to reschedule despite repeated attempts to reach them. Two more Google reviews from November 2025 called the business "very unprofessional" and "terribly ran" without giving further detail. Angi and HomeAdvisor both show this same split in their numbers: 75% five-star and 25% one-star, out of four ratings each. A few other things are worth knowing before booking: BuildZoom notes the company doesn't need a state license for general contracting work, but it also lists an inactive asbestos contractor license for the business that the state's own list shows as having been cancelled at one point. Angi and HomeAdvisor also disagree on how long the company has been in business — 17 years in one spot, 8 in another. Given how split the record is, it's worth confirming scheduling and communication expectations clearly in writing before the job starts, and following up promptly if a start date gets missed.
