Boston BuildHERS LLC

Boston BuildHERS is a South Boston HVAC subcontractor whose name is the point: the company describes itself as 100% woman-owned, co-founded by Ronnie Kassiff and Suzanna Gal Gombos, who say they bring 19 years of construction experience to a business that is "just starting off on our own." The work it takes on is not the furnace-quit-on-Saturday call. It says it works directly with general contractors on small to medium-sized multifamily and commercial projects, with a stated focus on HVAC for affordable housing across Greater Boston. What is on the public record so far is institutional rather than word-of-mouth. Boston.gov lists the company among the participants in the city's SCALE program, which — according to a post from the Initiative for a Competitive Inner City — gave small, minority-owned and women-owned businesses technical assistance, one-on-one coaching and access to grant funding. A City of Boston equity-in-city-contracts page from October 2025 lists the firm under construction tradeswork with a WBE certification, and a December 2025 Beacon Hill Times item named it among the businesses at Mayor Wu's first Scaled Impact Celebration. The company itself says it is WBE-certified by both the City of Boston and the Commonwealth of Massachusetts, and Passive House Builder Certified by Phius. For a homeowner who needs a furnace serviced, this is likely the wrong number to call — the company presents itself as a sub to builders on multifamily and commercial work. For a general contractor or developer who needs a certified WBE HVAC subcontractor on an affordable-housing job in Boston, ask for references from the multifamily projects it has already finished, and confirm its certifications and licensing directly with the city, the state and Phius.
