Five indoor mini-split heads, two outdoor units, and controls integrated with an existing natural-gas boiler: a July 2026 customer described that installation by Modern Energy and said the system worked as intended. The company says it is locally owned, with headquarters in Worcester, and offers heat pumps, air conditioning, insulation, solar, and commercial VRF installations. Google lists a 4.9-star average from 198 ratings. Customers describe both system planning and the work inside their homes. A May 2026 reviewer evaluating a whole-home ductless system for an older Victorian house in Worcester said Cesar completed a Manual J load calculation, explained equipment sizing, compared Bryant and Mitsubishi options, and answered questions without pressure. A different May customer described a completed whole-home mini-split installation: Dan helped with the energy assessment and HEAT loan process, Lori organized loan documents, and Jimmy, JV, and Stan completed the work in about a day and a half. That customer said the house was left as clean as before the job. Insulation work also draws specific praise. An August 2026 customer said Jay, Tim, and Jose arrived on time each day for insulation and weatherization work. Jay discussed project concerns with the customer, and all three answered questions. In a December 2025 review, another homeowner described a ducted heat-pump retrofit of a Victorian-era house. Ryan arranged several walkthroughs to develop a plan, Chris organized the installation around the customer's schedule, and Tim's team adjusted to surprises while preserving the home's older style. Modern Energy LLC's Massachusetts home improvement contractor registration is active. Its BBB page gives it an A+ grade and lists accreditation. A September 2025 customer described a different experience with a $38,000 system at a rental house. They said only part of an expected $10,000 Mass Save rebate arrived, and Jeff did not help after they provided documentation. They also reported unanswered requests for a printed manual and warranty, and unanswered questions after paying $375 for cleaning and maintenance. In contrast, a February 2024 customer said the team helped with Mass Save paperwork for a whole-house heat-pump installation involving electrical upgrades and basic carpentry, enabling them to take advantage of the full rebate.
“Modern Energy is a 2025 Inc. 5000 honoree”
Jay, Tim and Jose were wonderful! I had insulation/weatherization work done. They Showed up on time each day. Very clean, respectful, efficient, thorough team. Jay came to me with any concerns he had about the project and talked them out with me-they didn’t make any decisions for me, they helped me make the best decisions for myself both financially, and for my home! All three of them were happy to answer all of my questions and I had a lot! They were a great bunch of guys with fun personalities! I highly recommend this company, Jeff Vik was great, Caroline in the office was great, and Lori who obtained-the permit for the work to be done and helped with the final payment was great as well. Thank you, Jay, Tim, and Jose- you were all amazing! I highly recommend this company and especially this team!
I really can't say enough in respect to the mini-split installation at my residence I experienced with Modern Energy. From the initial consult and walk-through of my home, to the various HPump design solutions presented, and finally the care and attention to details throughout the system installation process, Modern Energy delivered an exceptional customer experience. The ME team for my project comprised of Will, Steve, Jordan, Ryan, and Adam. All were professional, courteous, and really knowledgeable. My project consisted of 2 outdoor units, and 5 ductless mini-split heads and the system works exactly as intended. Included integrated controls with my existing ng boiler heating system. Thank. you for everything. A++ company.
