The Evolution of Rheem Ownership and Brand History
The Rheem Manufacturing Company was established in the mid-1920s by brothers Richard and Donald Rheem in San Francisco, California. The business initially built its reputation manufacturing water heating equipment, an industry segment where it remains a dominant force. The company expanded into cooling systems during the mid-1950s with the launch of its signature Rheemaire line.
Although founded as an American family business, ownership shifted in 1988 when the enterprise was acquired by Paloma Industries, a multinational Japanese corporation known for heating, water, and gas appliances. In 2023, the organization transitioned into the Paloma Rheem holding structure. Despite international corporate ownership, Rheem continues to operate as an autonomous subsidiary, retaining control over its HVAC design and production lines.

Despite being owned by a Japanese parent corporation, Rheem has maintained its operational roots in North America. The brand relocated its corporate headquarters to Atlanta, Georgia, in 2007 and continues to manufacture a significant portion of its inventory inside the United States.

These include a 215,000-square-foot facility in Mexicali and an expansive 290,400-square-foot plant located in Nuevo Laredo. Equipment serial numbers contain specific location codes that reveal the exact factory where an individual unit was assembled.
System Longevity and Reliability
Air conditioners produced across Rheem’s domestic and international plants are built to standard commercial and residential specifications. When installed correctly and serviced annually, a modern Rheem central cooling system offers an operational lifespan ranging between 15 and 20 years.
