Haldeman Inc.

Haldeman Inc. has anchored itself in Los Angeles since 1933, making it one of the oldest continuously operating HVAC supply operations in Southern California. With 73 verified reviews yielding a 4.5-star average, the company draws both mechanical contractors and engineering professionals to its counter. The company maintains two staffed locations: its primary Los Angeles office on Tanager Avenue in the 90040 ZIP code, and a San Diego branch serving Kearny Villa corridor clients. Beyond walk-in counter service, Haldeman extends access to bidding opportunities, real-time inventory checks, and technical product documentation through its proprietary Etools portal.

What distinguishes Haldeman from typical supply houses is its manufacturer portfolio and distribution model. As a stocking representative for Loren Cook, the company supplies commercial-grade centrifugal and exhaust fans. Its Ruskin partnership delivers dampers and louvers used in commercial building envelopes, while Krueger Products provide air distribution hardware. Additional lines include Smog Hog smoke elimination equipment, Honeywell gas detection systems, Reznor heating units, and Springair airflow products. This breadth covers commercial new construction, tenant improvement projects, and large-scale replacement work across institutional settings.

Reviewers routinely call out individual team members by name. Edwin earned praise for going above and beyond on urgent requests. Longtime customers highlighted Manny and Junior for their persistence in securing hard-to-get items and keeping clients informed. One contractor noted the counter staff fulfilled complex multi-line orders within minutes, while another appreciated the early 6 AM opening that accommodates jobsites starting before standard business hours.
