This only happened recently, but i've already replaced the fuse 3 times within the last month and a half. Anybody know what could be happening and possibly how to fix it?

i have the double poker type fuse box if that helps. And If I do need more refrigerant would be expensive to add some?

If the fuse blows within a few seconds of the compressor turning on, there is probably an electrical problem such as a shorted motor winding or shorted wire. A system that otherwise seems to be cooling normally and only blows a fuse occasionally could be an indication of a non electrical problem - usually excessively high pressure presented to the compressor with a corresponding rise in the compressor motor current. This is almost never caused by low freon levels, but certainly can be caused by excessive freon in the system.
Temperature can also be a factor. If the fuse or breaker only goes out in extremely hot weather it is almost always a high pressure problem. This can be caused by a dirty freon filter or other partial restriction in the freon system. It can also be caused by the freon traveling from the compressor not being adequately cooled - perhaps due to a bad compressor or air handler fan; dirty coil(s) or an air filter that needs replacing.
I would also reccomend that you check and make sure that the fuse(s) you are using are the proper size specified for your unit. Do not under any circumstances use a larger amperage rated fuse because you will risk serious damage to you system.
Beyond checking the simple things, a set of pressure gauges and an amp meter would be required to diagnose the problem. If you don't own these please consider obtaining the services of a professional.

it depends on many things, make sure both coils are clean, your condenser fan or compressor are overheating. the compressor could be low on refrigerant. Give us more info too help you out.
If you are low on refrigerant you'll need a service tech, he'll check each component & add refrigerent if necassary, this will most likely cost you around 100.00, most of these answers are a joke, they think your using a window unit for one, but also to increase the fuse size is never even an option, as this could damage the components in the unit. The fuses are blowing for a reason and you need a complete diagnosis

Don't replace the fuse with a larger size - the existing fuse capacity is designed to protect the existing wiring circuit from handling too many amperes and overheating - and possibly causing a fire.
Most likely, the wire size from the fuse panel to your A/C unit's power outlet is undersized to the A/C requirements, so your A/C keeps blowing the fuse.
As another person said, have a qualified electrician inspect your wiring to that outlet and either upgrade the wiring to a larger wire size & fuse, or connect the A/C unit to another outlet that provides a higher ampere capacity.
You also might have other appliances and loads collectively trying to draw too much power from this fuse & circuit. In that case, move the other loads to other circuits.

If you have a screw in type of fuse your wiring is in desperate need of updating. I would not even attempt to try a larger fuse. I strongly recommend that you get a certified electrician to look at re-wiring your house. (it's cheaper that replacing the whole structure)

You are pulling more juice than there is available....turn off other major appliances, or run them from another breaker
and try using a higher amp fuse....at least a 30 amp if it is the old screw-in type or a 60 amp double pole breaker, if that is what you have.
This worked for me!

If it just started doing this recently I would suspect that it is low on refrigiant and or the fins are blocked causing the compressor to pull higher than normal amps

It's pulling more amperage that the fuse can handle...try using a bigger fuse....but have an electrician look at your wiring to ensure that the circuit can handle the added amperage safely.

The circuit it is on is obviously overloaded.
Try plugging it in on a seperate line, that should work.
