Holden Mechanical Contractors is a Worcester-based commercial and industrial mechanical company offering HVAC, heating, air conditioning, refrigeration, plumbing, piping, fabrication, installation, and maintenance services. Its website describes the company as a Thielsch Engineering division and says the larger organization is employee-owned. The only available customer review, from February 2024, is a one-star complaint about aggressive driving by a company vehicle rather than completed work. The Massachusetts registry lists HVAC license 30-SM-B as expired, while BuildZoom shows separate license claims MA30757P and 30; confirm current licensing before booking.
Nearly ran me off the road twice on 190. Gray truck with racks. Aggressive driving and carelessness isn't a great look, especially when your vehicle has the company name on it.
Typical Greater Boston range for this kind of work, from regional averages — not a quote from Holden Mechanical Contractors, Inc.. Use it to sanity-check bids, then get the real number in writing.
Estimated range
$5,000 – $11,400
