How to determine the date of production/manufacture or age of Singer® brand HVAC Systems.
The date of production/manufacture or age of Singer brand HVAC equipment can be determined from the serial number located on the data plate.
In 1982, Singer became a climate control system of Snyder General Corp. and the “Singer” name was dropped (no longer used in climate control systems after 1982). By 1984, Snyder General operations included Arcoaire, Comfortmaker, and McQuay branded systems. Snyder Genral purchased American Air Filter (AAF brand) in 1988. The Arcoaire and Comfortmaker lines were later sold to Inter-City Products (ICP) in 1991.
Any system bearing the brand name “Singer”will most likely predate 1982, and will have exceeded typical average service deign life. The following serial number examples are typical of SnyderGeneral Corp. branded systems, and not necessarily specific to “Singer” brand.
