How to determine the age of your HVAC system

Knowing the age of your HVAC can help prevent inconvenient and expensive failures

If you’re like most homeowners, you don’t think about the age of your furnace or air conditioning system until it stops working. At that point, you’re in an emergency situation and need a replacement immediately.

But, if you know the age of your furnace and/or air conditioning system, you can be way more proactive. This is especially helpful when you want to switch from a old, fossil fuel powered technology to a clean, modern heat pump.

You'll want to start making a plan for any appliance that is 10 to 15 years old. To determine the age of your equipment, try the following.

Manufacturer’s label

The installation date is often printed on the manufacturer’s label. These are usually affixed to the front or top of the furnace or air conditioner.

Serial number

Serial numbers can be decoded to get the manufacturing date.

The number is usually printed somewhere on the appliance. If you don’t see one printed on the outside of the appliance, turn off the power before digging any deeper to stay safe! Check for serial numbers on the fan and its blades as well as on the interior of any doors to the appliance.

To decode the serial number, find your brand using the search in the upper right and decode it based on the pattern:

Service tags

Check to see if there are any tags on the appliance from past maintenance. This may list a date that the appliance was installed, or at least give you a minimum age.

Contact the manufacturer

If all else fails, you can contact the manufacturer. They may ask for photos of the appliance or be able to give you specific information on where the serial number is located.
