How do I find my York serial number?
Finding the serial number for your York HVAC unit is essential for a variety of reasons, including warranty claims, servicing, and determining the age of your unit. Here’s a simple guide to help you locate it:
The most straightforward method to find your York serial number is by inspecting the unit itself.
- Outdoor Unit: For central air conditioners and heat pumps, check the outdoor compressor/condenser unit. Typically, there will be a label or sticker on the side or at the back of the unit.
- Indoor Unit: For furnaces or air handlers, open the door or panel to access the inside of the unit. The serial number is often on a label affixed to the inner part of the door or the body of the unit.
If you have retained the user manual or warranty card that came with your unit, it’s likely that the serial number is mentioned there. Often, when the equipment is installed, the installer might note down the serial number in the manual or on the warranty card for reference.
After you find the location of the York serial number, the next step is to decipher the code in it. This way, you can identify how old your unit is.
How to Read York Serial Number
Over the years, York has used various formats for their serial numbers, but let’s break down one of the most common formats. The typical format used for many years by York is a combination of letters and numbers.

- The First Letter (W): This often represents the manufacturing plant. W is for Wichita.
- The Second and Fourth Characters (0 & 5): This is the third digit of the year of manufacture. In our example, it’s 2005. If it was a 1 and 1, it would be 2011, and so forth.
