Nicholson Heating, Cooling, Plumbing & Electrical

Nicholson Heating, Cooling, Plumbing & Electrical is based at 71 Whitney St in Holliston and presents itself as a residential HVAC, heating, air-conditioning, plumbing, and electrical provider. BBB lists the company as accredited with an A+ grade and four years in business, while Angi and HomeAdvisor pages state 17 years of experience; the conflicting tenure figures are worth clarifying directly. The company is hired for HVAC installation, maintenance, repair, indoor air quality, plumbing, water heaters, boilers, sump pumps, and electrical work. Angi and HomeAdvisor each show one five-star review from November 2024 describing the team as great to work with. The visible BBB reviews are substantially more critical. Undated reviewers describe disappointing recent experiences, a leak, and a defective Carrier heat exchanger with labor charges they say were three times higher than competing providers. Those accounts are specific enough to make equipment diagnosis, warranty responsibility, and labor pricing important questions before booking. The company may suit homeowners seeking a broad HVAC and plumbing provider, especially where electrical work is part of the project. Before scheduling, confirm the current licensing status and the exact scope, warranty coverage, and labor rate in writing; BBB lists several Massachusetts license numbers, while BuildZoom notes some license records as not verified.
