All Renewable Energy, Inc.

All Renewable Energy is a Newton-based HVAC and plumbing contractor that says it's spent more than 30 years working large-scale multi-family, commercial and mixed-use development projects, alongside 24/7 emergency service. Founder Harold Coxall started in HVAC in the late 1970s; his son Zachary joined in 2012, and Tina Mingace serves as vice president of operations. Its Massachusetts HVAC license is active, and a 2023 trade-press subcontractor listing shows the company working a large commercial project alongside more than a dozen other specialty contractors. The written reviews are thin but point to a real, recurring problem: installed systems that don't stay fixed. In a 2024 review, a homeowner said the company's customer support was responsive but kept coming back to address installation issues through a first winter and summer, with occasional water issues from an attic unit still unresolved. A separate 2022 review described repeated visits that never fixed an HVAC system the company had installed. Those two complaints, two years apart, describe the same underlying pattern rather than one bad job. The company has also been named as a defendant in a lawsuit brought by another HVAC-industry contractor, per a legal-industry docket listing that gives no further detail on the claims or outcome. For a large commercial or multi-family HVAC project, the company's licensing and long project history are real credentials — but the residential-installation complaints above are specific and recurring enough to warrant asking pointed questions about warranty coverage and callback response before signing for new equipment.
