Ritchie Engineering Company

Ritchie Engineering Company has operated from Minneapolis for more than five decades, manufacturing the Yellow Jacket brand of HVAC tools and gauges that technicians rely on across the Upper Midwest. The manufacturer holds an A+ rating standing with the Minnesota Department of Employment and Economic Development and appears in local business directories under HVAC equipment suppliers. Nine customer reviews on file yield a 3.1-star aggregate rating, with feedback spanning both strong endorsement and pointed criticism. The company's toll-free line at (952) 943-1300 connects callers to support staff weekdays from 6 AM to 5 PM.

What distinguishes Ritchie Engineering from regional HVAC supply houses is its dual role as both product manufacturer and authorized service center. The Yellow Jacket brand produces refrigerant manifold gauges, low-loss hose fittings, and system analyzers designed for heavy commercial use, and the company honors warranty claims for units serviced in-house. Website materials reference the Yellow Jacket E-Commerce Store for direct purchases, product registration portals, and downloadable technical resources including SDS documents and firmware updates. Technicians have noted the company will accept disassembled equipment for repair, a courtesy that several five-star reviewers specifically highlighted.
