Manufacturing, clean rooms, R&D facilities and numerous other environments require well-designed and properly installed piping systems. Lake HVAC’s team of licensed pipe fitters, plumbers, and certified welders work together to ensure your piping systems are installed to meet the exact specifications and the demands of your system.



Lake HVAC specializes in steam, chilled water and hot water piping systems. All of our mechanics possess unrestricted licenses that allow Lake to offer our customers the ability to install compressed air, nitrogen and specialty water systems. Our headquarters in Stoneham contains a 10,000 square foot pipe-prefabrication shop with the ability to minimize field welding and material handling, in turn lowering the end cost to the customer.



Licensed in Massachusetts and New Hampshire, our experienced pipefitters and plumbers are certified in MIG, TIG, and orbital welding.
