How old is my York air conditioner?

1. Find the rating label: On the side or back of the outdoor unit. Some have a second label on the indoor coil.
2. Take a photo of the whole label, or note the model and serial numbers.
3. Check it on Appliance Age. It is free, and no account is needed.

On the side or back of the outdoor unit. Some have a second label on the indoor coil.

Keep the model, serial and any separate production code or printed date together. Not every serial number contains a publicly decodable date.

York serial numbers depend on the equipment family

York HVAC identification and format differences · Sources checked October 12, 2026

Use the complete equipment rating plate when checking a York furnace, air conditioner or heat pump. A commercial unit’s serial layout is not necessarily the layout of a residential furnace.

For example, a Johnson Controls VITALITY manual documents a commercial code containing a plant identifier, a decade digit, a month letter and a year digit. This is evidence that a universal “first two digits equal year” shortcut is unsuitable across product families.

This commercial illustration is not a residential York decoding rule and is not a promise that our lookup supports this format. If the lookup cannot establish a date, ask the dealer with the full model and serial.

• York official product and dealer support

Use the format that belongs to this product family. A printed production date, a supported serial code or manufacturer confirmation can establish the age. Repeating year codes may leave more than one possible year; a model-series introduction date helps narrow the range but does not date your individual unit.

Air Conditioners typically last 12 to 17 years. Use, water quality and maintenance matter more than the brand. Keep 60 cm clear around the outdoor unit and rinse the coil from the inside out each spring.

Parts that wear out most often on air conditioners:

• Run capacitor
• Contactor
• Condenser fan motor
• Air filter
• Thermostat

Have the model number from the rating label ready so the parts fit.

Every York check is compared with Health Canada, U.S. CPSC and U.S. NHTSA recall notices.

Questions

How do I find out how old my York air conditioner is?

Find the rating label (On the side or back of the outdoor unit. Some have a second label on the indoor coil), then enter the serial number or a photo of the label on Appliance Age. It checks supported serial date codes or a printed date for you, free; some formats need more information.

Where is the serial number on a York air conditioner?

On the side or back of the outdoor unit. Some have a second label on the indoor coil.

Can I tell how old my York air conditioner is by the model number?

The model number tells you which model it is, not when your unit was made. Look for a manufacture date or a supported date code in the serial number, printed next to the model number on the same label.

Can I decode a York serial number myself?
