Interstate Mechanical Services

City-funded organization

Interstate Mechanical Services, Inc. is a mechanical contracting company headquartered at 355 Sills Road in Yaphank, NY, founded in 1997, according to its own website, which states its goal has been "to build the finest mechanical contracting company in New York, New Jersey, and Westchester." Checkbook NYC shows the firm holding one active city contract, an $11.8 million Health and Hospitals Corporation (HHC) agreement titled "EMERGENCY TIE IN AND BOILER UPGRADE," part of 5 registered HHC contracts since 2022 worth $19.3 million awarded all-time and $7 million paid to date. A $4.1 million condenser water piping contract and a separate $2.4 million contract, both now expired, were also tagged "competitive sealed bid." Two smaller contracts, a $908,984 condenser water riser repair and a $168,132 temporary chiller rental, are tagged "Emergency," together making up the 6% of the firm's contract value, $1,077,116 across 2 contracts, that Checkbook NYC's own award-method tags show was awarded without a fresh competitive bid.
