Don't turn it on again until you get a certified repair person in.

If your outdoor unit is running for 30 minutes, it may be working too hard...As the others have said, clean the indoor and outdoor coils, change the indoor air filter.
If the fan motor is running, it may need lubrication or the bearings are shot. Cut the power to the unit, and open the top to access the motor. Hold the fan blades in your hand and spin the blades. If the bearings are shot, you will feel grinding. Try to wobble the motor shaft. If it goes up and down along the axis of the shaft, it is ok. If it goes back and forth any, your bearings are shot and you will need a new motor. If the shaft spins freely, look for lubrication ports on the motor. They may be red or yellow plugs on the side of the motor that lead to the shaft. A few drops of 3-in-1 or other high-grade machine oil will work.
If there are no lubrication ports, you might try a very good penetrating oil such as WD40 or your favorite along the shaft. Spray the lube on the shaft and let it sit for a few minutes to lube the bearings. spin it by hand again and see if it moves easier.
Put the lid back on, and restore power. Monitor the operation of the unit.
The motor may also be overheating because it is drawing high amperage. A weak capacitor may also cause the motor to bog down and draw high amps. It takes a special instrument to measure the capacitor, and training that can't be learned from a message board. If the unit does not run properly after lubrication, call in a pro. Ask him/her to let you know the amps the fan is rated for, and what it is pulling. Ask him/her to let you know if the capacitor is working properly.

If it's central air with an outdoor unit, make sure it's clear of debris and can pull in air freely. Replace the furnace filter. If it's a window unit, check to see that the intake grill is clear and it's emptying the condensate (water it pulls from the air) without restriction. Make sure it's tipped downward out the window, too. Most of the time it's all about air flow. If this is an older window unit, you might want to replace it. The newer ones are more efficient and use less electricity for a lower bill!
