Plan on at least $400 for a MacBook Air screen replacement.
Out of warranty, Apple charges around $400–$600 depending on the model year. Third-party shops can be cheaper ($250–$400) but you risk losing True Tone or getting a lower-quality panel.
Apple’s official fee for a 13-inch MacBook Air (M1, M2, M3) is usually $499 if you go through their mail-in service. Walk-in may be similar. Older Intel models drop to about $350–$400, but parts are getting scarcer. If you have an M2 or M3 Air, the screen assembly is glued and includes the whole lid — nothing is user-serviceable, so labor adds up.
Third-party repair can save you $100–$150, but make sure they use an “OEM” or “grade A” LCD. Cheap replacements often have uneven brightness or color shift. And if you care about Apple’s True Tone calibration, third-party panels rarely support it unless they reprogram the display controller, which not all shops do.
If your MacBook Air is otherwise in good shape, it’s usually worth fixing. If it’s a 2018–2020 Intel model with a cracked screen and other issues, it might be smarter to put that money toward a new one.
