Paradigm Energy Services

Paradigm Energy Services is a Somerville-based energy efficiency company that runs the home energy assessment and project-manages the work, rather than doing every job itself — it contracts the actual heating, electrical, and weatherization installs out to partner crews. BBB's own profile lists 14 years in business with an A+ rating (not accredited), and Google shows a 4.7★ average across 16 ratings. Several reviews describe that assessment-and-referral model working well. In a January 2026 review, a Somerville homeowner doing a full-home system overhaul of an 1890s house praised how thoroughly the team explained equipment selection, safety, and labor tradeoffs. A March 2025 review described a detailed condominium heat pump install carried out by contracted McMahon Plumbing & Heating, with the technician addressing every concern over several days of work. A February 2025 review credited the company with scheduling an assessment within weeks and getting new air sealing and insulation installed without any sales pressure. Two reviews describe real problems with the installation side. A July 2025 review described repeated issues with the crews doing the physical work — a worker leaving a mess after using the customer's bathroom, property damage, and a job left unfinished. A December 2024 review, while naming and praising the individual electricians and technician on the job, described a project that ran months over schedule with no way to reach a manager to sort it out. Given Paradigm assesses and refers rather than doing the installation itself, it's worth asking upfront which partner crew will handle the physical work and how the company handles it if a job runs long.
