About

Western Allied Corp. is a Santa Fe Springs-based commercial HVAC contractor that has designed, installed, and maintained mechanical systems across Southern California since 1960, bringing over 65 years of engineering expertise to property and facility managers throughout the Los Angeles basin. The company covers the full mechanical scope — new construction, retrofits, design-build projects, and 24/7 service and maintenance — making it a single-source resource for complex commercial facilities. Western Allied operates a Local 105 union sheet metal shop and employs United Association Local 250 piping personnel, with pipe prefabrication capability ranging from 2-inch to 16-inch-plus systems. On the controls side, Western Allied brings over two decades of open-protocol expertise in LonWorks, BACnet, and Modbus, positioning the company as a Southern California leader in building automation for facilities that require integrated mechanical and controls solutions.

Service agreements include both preventive maintenance and full-service contracts, with 24/7 availability and multi-site coverage — practical advantages for property managers overseeing multiple commercial assets across the region.
