A little oil will escape with the refrigerant. Look for a blackish oily stain on the tubing. A service tech might use electronic sniffing equipment.
You can find a Freon leak in a home Ac unit by using a leak detector. These instruments are capable of detecting trace amounts of Freon and pinpoint leaks.
It a word, no. Without a leak, the freon level in your unit should stay the same for years and years.
First you need to find the leak, you should never lose refridgerant unless there is a leak.
Freon can leak. Since it will do so in the form of an invisible, odorless gas, it is very difficult to observe such a leak.

Never, unless you have a leak.
