3 beeps usually indicates RAM or RAM socket failure. If you have both RAM sockets filled, try taking one out, and see if it makes a difference. This is to isolate a bad RAM stick or socket, which fails occasionally. If it fails again, swap the RAM to the other socket leaving one empty.

There's no RAM slots on a MacBook Air.

Try to reflow the RAM ICs with hot-air and a good quality flux!
I could repair 8 out of 10 Macs! (you should first practice on a spare board, since it helps to move the chips a bit when the solder is melted!)

Thanks piernov. Sorry, I confused it with the 2012 MBP. RAM reflow is the best option.
