Many home AC units are sealed, and there is no way for a homeowner to add refrigerant.

Please articulate your question so it is comprehensible .
That would depend on the type of refrigerant that is being used.
actually for the a/c have 2 units,one is the indoor unit and the other is the outdoor unit, and there will be a refrigerant gas flowing in between the two units (in the copper pipes) when the refrigerant comes to the indoor unit it comes with a cold format .and when the chilled refrigerant comes in the way of the hot air ,the refrigerant becomes hot and the air becomes cool. (there will be a blower inside the indoor unit to blow the air across the refrigerant pipe's and hot refrigerant now goes to the outdoor unit (i.e condenser), where the outside atmosphere air comes across the hot refrigerant so that the hot refrigerant becomes cool and the cold air becomes hot. so, the indoor unit is maintained in a cool temperature and the outside outdoor unit is maintained at a hotter temperature.
Is it a new or an old window unit? Assuming your looking to refill it I will assume it is an old window unit which most likely uses R-22 refrigerant. R-22 is an ozone depleting refrigerant that is being phased out but should be available until 2010. There should be a label on the window unit stating which refrigerant is used.
I have a 99 durango and the amount of refrigerant needed for the single unit and double unit are listed under the hood on top of the radiator.
The refrigerant pressures are dependent on the type of refrigerant.
Depend on what is the Horse Power of the split unit. For Example 1Hp split unit can go up to 0.2 refrigerant ton maximum. http://weightlosstreatnow.com
If you have a split unit - one with an outdoor condensing unit and an evaporator coil built into the furnace indoors, the refrigerant type will be shown on a label or engraved metal plate attached to the condensing unit. The amount of refrigerant will vary, depending on the diameter and length of pipe connecting the two units. Most window air conditioners have an hermetically sealed refrigerant loop and cannot be recharged in the field, although they may also list the refrigerant type on a data plate somewhere.
Most home systems use R-22 refrigerant. R-410a, known as PURON, is also an increasingly used refrigerant. If you see a pink sticker on the outdoor unit, it will say on the tag with the model and serial numbers r22 or 410a. "Freon" is a trademark of DuPont, and is NOT the real name of refrigerant. "Freon" was R12 and is no longer made.
You would not smell the refrigerant as it is odorless, you may however smell the oil that circulates along with it. But if the leak was that large where you could smell it, it most likely would have been one single event NOT a continuous one and the unit would be totally out of gas and non functional.
