## The honest read

A customer in July had Gabe and Michael out to deep-clean the mini splits and ended up writing about how they fielded questions from two kids and got on with the dog. That is the texture of most Endless Energy reviews: a technician named personally, on time, explaining what he did — CJ, Antonio, Eydan, Aaron, Travis, Brendan, Mike.

The company is family-owned, works out of Needham with offices in Marlborough and Randolph, and says it has been in Massachusetts since 1980. Its Massachusetts sheet metal licence, 934-SM-B, is active on the state registry under Endless Energy New England Inc. It runs Mass Save home energy assessments, calls itself a Home Performance Contractor since 2015 and a Mitsubishi Diamond Contractor, and covers heat pumps, mini splits, insulation, plumbing and electrical work.

Maintenance and follow-up are where the praise sits. A customer whose heat pumps and six mini splits were installed by the company keeps them on for the annual service. A June customer with a leak in one unit had a crew out first thing the next morning. In April, another had the AC prepped after a winter install and the technician checked for questions before leaving, and an Angi customer that month had a burnt-out compressor replaced under warranty at no cost. Brendan walked a June customer through an insulation project and the Mass Save paperwork; Mike Heil's April assessment came with ways to cut energy use before the heat pump quote was discussed.

Getting to that technician is where two 2026 customers ran into trouble. In July one described a chat with typing sounds and background noise that eventually admitted it was an AI, then said it called back three times in two hours after being told to stop. In May another had the repair man arrive on the wrong date and described being messaged relentlessly. The Better Business Bureau accredits the company and grades it A+, and also lists nine complaints on file. Going further back, a customer writing in March 2014 said the company was paid in advance and did not file the documentation with the town, and that the delay was the company's doing rather than the town's.

For heat pump and mini-split work — a new system, the annual service, or a Mass Save assessment — the field crews are the reason to call. Book through a person, confirm the appointment date in writing, and settle who files which rebate and permit paperwork before the visit.

**Strengths:**
- Named technicians — CJ, Eydan, Antonio, Aaron and Brendan cited by customers
- Annual servicing — heat pumps and mini splits maintained by the installer
- Next-morning repairs — a June unit leak was fixed the following day
- Rebate paperwork — Mass Save documentation handled alongside the work
- Warranty follow-through — a burnt-out compressor replaced at no cost

**Concerns:**
- AI phone contact — repeated automated calls after a customer opted out
- Wrong-date visit — a May repair technician arrived on the wrong day
- BBB complaints — nine on file at the Better Business Bureau
- Town paperwork — a 2014 customer said filings went undone after prepayment
