Mechanical & Gas Fitting

Certified Mechanical Systems & Gas Fitting

CRS Mechanical designs and installs high-performance mechanical and gas fitting systems for commercial and industrial facilities. From chilled water loops to high-pressure gas connections, every system is engineered to spec, pressure-tested, and fully documented for compliance with New Hampshire building codes and safety regulations.

Services Include:

  • Installation and connection of gas lines for boilers, furnaces, water heaters, and commercial appliances. All work performed in-house by licensed technicians—no subcontractors.

  • Custom piping systems for hot water and steam distribution in commercial heating applications. Designed for durability, energy efficiency, and long-term performance.

  • Precision piping for commercial refrigeration and chilled water systems, using materials tailored for temperature control, pressure ratings, and corrosion resistance.

  • Design and installation of pump assemblies, headers, and distribution manifolds for HVAC and process water systems. Balanced for flow efficiency and redundancy.

  • Professional-grade pipe insulation to reduce heat loss, prevent condensation, and improve system efficiency. All systems clearly labeled for safety and serviceability.
