Nicholson Plumbing, Electrical, Heating, and Air Conditioning is a Holliston-based company that says it's family-owned, with 16 years serving MetroWest towns like Framingham, Natick, Newton, and Waltham with plumbing, HVAC, and electrical work around the clock. It's grown into one of the bigger operations in the area — the review volume alone, more than 3,100 Google ratings averaging 4.8 stars, points to a large field staff rather than a one-truck outfit.
That team is also where the praise concentrates. Across dozens of recent reviews, the same names come up again and again — Luis Andrade, Mike Adams, Steve, Jimmy Silver, Ian — each credited for walking a homeowner through a diagnosis before doing the work. A 2025 reviewer described calling about a burst pipe at 8:30 at night and having a technician on-site the next morning, pipe fixed within the hour. Another, that same year, described a Sunday emergency water heater replacement done start to finish, including a new expansion tank and pipes, with the work area left clean.
The friction shows up on the business side rather than the bench. A run of 2026 reviews describe pricing that struck customers as steep for the scope of work — one homeowner said a routine shut-off valve swap, a roughly half-hour job with a part costing about $25 at a hardware store, was quoted at $597; another paid a $99 diagnostic fee only to be quoted $856 to install a dishwasher they already owned. Separately, a few 2026 reviewers who pay for maintenance plans said their seasonal AC or furnace checkups got pushed out months, and one reviewer whose mini-split compressor failed in early summer said the repair dragged on for over three weeks without air conditioning. Online opinion on cost is split even beyond the reviews: a 2024 Reddit post called Nicholson price-competitive and highly knowledgeable, while a 2026 Reddit comment joked about a roughly $40,000 quote for a comparable system.
The company holds a Better Business Bureau A+ rating and lists plumbing, electrical, and sheet-metal license numbers there, several current through 2026-2028 — not independently verified here, but a consistent presence across the trades it advertises.
For a straightforward repair or an emergency, Nicholson's size means someone is usually available fast, and the technician-level reviews are consistently strong. For anything beyond a small job, get a written quote up front and ask directly about current maintenance-plan scheduling before committing.
