    Frequently Asked Questions

    How do I find my HVAC system's age?

    You can find your HVAC system's age by locating the serial number on your unit (usually on a metal data plate) and using our free decoder tool. The serial number contains encoded information about the manufacture date, which varies by brand.

    Where is the serial number on my HVAC unit?

    The serial number is typically found on a metal nameplate attached to the unit. For outdoor units (air conditioners, heat pumps), check the side or back panel. For furnaces, look inside the blower compartment door or on the side of the cabinet.

    How long do HVAC systems typically last?

    Most HVAC systems last 15-20 years with proper maintenance. Air conditioners and heat pumps typically last 15-20 years, while furnaces can last 20-30 years. Knowing your system's age helps you plan for replacement.
