Amana® HVAC age

How to determine the date of production/manufacture or age of Amana® brand HVAC Systems.

The industry average service design life for most forced air furnaces is 15-20 years, and the industry average service design life for most air conditioning condensing units is 10-15 years. The average service design life of boilers can vary from as little as 10 years to as many as 50 years depending on the type and quality of materials used in their manufacture. Routine upkeep/maintenance, regional weather/climate, and location/placement of the mechanical systems will all play critical roles in the longevity of these systems.

Parent Company: Operating as independent subsidiary of Daikin Group

Subsidiaries or other related brands: Goodman (GmC), Janitrol, Daikin

What eventually became Amana^®as we know it today began as a startup company in 1934 called "The Electrical Equipment Company" in Middle Amana, Iowa to manufacture commercial walk-in coolers. 2 years later, the founder (George Foerstner) sold the company to the Amana Society. The company was renamed the "Electrical Department of the Amana Society" and Foerstner remained on as manager. In 1949 the company was sold to an investment group and renamed "Amana Refrigeration, Inc." In 1954 Amana Refrigeration began making air conditioners and officially entered the HVAC market along side their popular refrigeration appliances. Raytheon, which had invented the microwave oven in 1947, purchased Amana Refrigeration in 1965 and began expanding the kitchen appliance division with the first consumer version of the microwave called the "Radarange". In 1986, Amana still under Raytheon ownership invents the revolutionary tubular heat exchanger for gas furnaces, which is now found in many brands of gas furnaces and packaged RTU's. In 1997 The Goodman Corporation purchased Amana (including the HVAC and small appliance divisions) from Raytheon. 4 years later, Goodman officially separates the appliance and HVAC divisions, and then sells the small appliance division to Maytag (now Whirlpool) in 2002. Goodman retained the Amana HVAC division and brand, and continued to produce systems under the Amana brand name. In 2012 Daikin acquires Goodman Manufacturing along with all its subsidiaries including Amana HVAC. The Amana HVAC brand systems are still produced today as part of Daikin Comfort Technologies Manufacturing.
