About A - 1 Refrigeration
Providing reliable, professional commercial refrigeration services since 1991.
Why Our History Matters to Your Business
Longevity in a technical and safety-conscious industry signals dependability. Since 1991 we have witnessed technological shifts—from older mechanical thermostats and straight HFC refrigerants to modern controls and low-global-warming-potential refrigerants—and adapted our practices accordingly. This experience means we can provide practical, forward-looking advice on system improvements, replacement timing, compliance and long-term cost management.
Our History and Mission

Over three decades later, that mission remains unchanged. Headquartered in West Allis, Wisconsin, our company has grown through consistent service, technical excellence, and a client-centered approach to refrigeration systems ranging from small walk-ins to large industrial chillers.
