Northborough’s Town Hall HVAC replacement is on hold while officials reassess a project whose early cost estimate bears little resemblance to the options now under review. The original estimate was reported as $1.3 million; an engineering peer review later identified two alternatives priced at $4.3 million and $5.1 million, according to the Community Advocate. The town is also considering a third option, but its cost has not yet been established.
The funding figures add another unresolved question. Town Meeting approved a $470,000 capital request in 2025 to help close the project’s funding gap, while a separate appropriations report cited a $1.25 million total cost and $780,000 previously appropriated, the Community Advocate reported. That $1.25 million figure differs from the $1.3 million estimate also cited in the reporting; the discrepancy has not been explained. Officials halted the replacement after determining that the available funding did not cover the anticipated work.
Comparable projects depend on what is included
A nearby project illustrates why municipal price tags are not directly interchangeable. Acton estimates its separate Town Hall construction project at $3.75 million, but that total combines HVAC and emergency-power replacement. The town’s funding plan includes a $1 million state grant contingent on an all-electric project and $2.75 million in borrowing; Acton’s 2026 Annual Town Meeting approved borrowing for the project, according to the Town of Acton and its meeting results. Northborough’s figures concern its HVAC project, so Acton’s combined-project estimate is context, not a like-for-like cost comparison.
A different kind of comparison comes from Dennis: minutes from a May 12, 2025, Alternative Energy Committee meeting record discussion of an HVAC upgrade for a DPW building estimated at over $2 million, while describing the figure as speculative—not an approved or completed project cost. The committee minutes document a separate building and an informal estimate, not a benchmark for Northborough.
The next estimate must fit a longer facilities plan
For Northborough, the immediate task is to determine the scope and cost of a workable HVAC option, then identify what funding might be available. Officials are vetting another system and have said the town may qualify for grants, the Community Advocate reported. The outlet also reported that initial design work is moving forward on a separate Town Hall flooring replacement estimated at about $700,000, with moving costs and other operational impacts excluded from that figure.
The HVAC decision sits among other building needs, making the order and timing of projects part of the challenge. A Massachusetts Division of Local Services capital-planning presentation identifies expected and remaining useful life as information municipalities can track in an asset inventory; that is general planning guidance, not a Northborough project schedule. The presentation offers one way to frame the broader task: weigh the HVAC work alongside other repairs without treating an early estimate—or a comparison from another town—as a final price.
