A1 Refrigeration was established in 1949 to provide a wide range of refrigeration, heating, air conditioning and plumbing services for individuals and businesses throughout Western Michigan. We are a family owned company specializing in the mechanical construction and service for businesses and homes of any size. Over the past 65 years, A-1 has evolved into two major divisions. Our commercial division is known as A-1 Refrigeration. We operate with the ideology that each should be strong enough by itself to offer great services to its specific clientele.
