Re: airconditioner of a 2001Hyundai Santa Fe
There is an EPA requirement that the amount of refrigerant required be indicated somewhere on the unit.
There are no moving parts that would cause a leak, but leaks can usually be found by looking for oily hoses, connectors, fittings, and coils, etc. The oil coats the inside of the system parts, and the leaking refrigerant will tend to push the oil out through the leak.
Unless you know the unit is low or out of refrigerant, then look for any cooling problems to be compressor related.

its possible to over fill the system with freon, that's why the gauges are so important,, if you take it to someone with those gauges, they can add a dye to the freon and it will show each and every leak if there are any, it may just be overcharged
If you put freon and the system still seems to be leaking then this means you have a leak in the system. Head to your nearest auto repair shop and have them do an a/c check. They will use a special dye that will pin point exactly where the leak is coming from. After you fix the leak, the repair shop can offer you an a/c revac and recharge to fill you whole system with freon after the leak is repaired.
this could be as simple as needing a charge. mobile air conditioner systems leak freon. It is just the nature of the beast. It is attached to the motor which moves and the car body which is fixed. It doesn't have a chance. there is a low pressure switch that protects the compressor if you lose too much freon and that could be why the compressor is not coming on. Freon cost a shop a little over $3 a pound when bought in bulk and labor is about a half hour. Look for a small independant that can do a/c for the best price. If this helps please reply and good luck
After a vehicle is two years old. I would have my air serviced or checked once a year. You can service it with a gauge from a local parts store. To make sure it has the proper amount of freon in it. And by adding a small can of oil 2.5 ounces to it. the freon guage should read between 25 to 44 psi on the low side and the high side should read 150 to 300 psi
