Highlights
- Fast response — fixed AC unit the same week as move-in
- MassSAVE help — assisted with rebate paperwork on install
- Custom layouts — creative heat-pump design for unusual homes
Black Diamond Energy is a Lynn shop built around one specialty: ductless mini-split heat pumps. The jobs people call them for run from a central AC unit that stopped working right after a move-in to a house with an unusual layout that needed a creative heat-pump configuration. Its Google page shows 5 stars across a small run of reviews (7 on file, 2023 to 2026), and two names keep recurring: Joe Watson, the founder and lead technician, and technician Mateus, both credited with showing up within the week and walking customers through the fix. In a 2023 review, one customer said the crew helped file the MassSAVE rebate paperwork and finished the ductwork carefully enough that it was barely visible; another, from the same year, described working directly with both owners on the project. The company is run by Joe Watson as founder and lead technician alongside owner Kevin King, according to its own site — a small, owner-involved operation rather than a large HVAC outfit. Black Diamond Energy is a fit for a straightforward ductless mini-split conversion, particularly one eligible for a MassSAVE rebate.
