How to determine the date of production/manufacture or age of Ducane® 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.
