How old is your AC? Find out in 10 seconds.

Snap a photo of the data plate, or type the model and serial numbers. You'll see the age, size, and refrigerant, and whether a repair still makes sense.

Where's the data plate?

Outdoor unit (AC or heat pump): a silver or white sticker on a side panel, usually near the electrical box.

Furnace or air handler: inside the front access door. Turn the power off before removing a panel.

Your photo is used only to read the label and is not stored.

Your results show up here

  • When it was built, and how old it is
  • Its size in tons
  • The refrigerant it uses
  • Whether a repair still makes sense
