Depends how big the leak is.

Touchdown:

There is no "best" way to find a leak.
Refrigerant leaks can sometimes be found as simply as just by observing things to having to use expensive equipment and a bit of ingenuety.

Why do you ask?

BTW: You must be properly licensed and certified to work on sealed systems. That being the case we are unable to dispense specific advice on sealed system repair.

Find Leak
I will use a properly certified & licensed repair man to fix the leak. They charge by the hour, so if I can locate the leak all he has to do is repair it. Do you think soap & water on outside the lines will work. Like finding a slow leak on a flat tire.

Thanks for your reply,

Touchdown:

Soap bubbles can and are used to locate leaks in some instances.
There are several reasons though why you may be wasting your time:
There may not be any or enough pressure in the system for bubbles to form . If the system is totally empty you could introduce soapy water into the system which would cause a compressor failure. The soap that tradespeople use has a sticking agent that allows the liquid to stay on the pipe longer to give the bubble time to form. The amount of refrigerant that comes out of a leak may not even be large enough to form a bubble in the first place. There are many places on the system that cannot be seen. If you find a leak and ask your serviceperson to repair it how can you be sure there is not more than one leak? If he repairs the leak you found who will carry the warranty?
Need more?

There is a reason why it costs so much!
Experience and literally thousands of dollars in test equipment make a well done leak repair a bargain.

Touchdown--

GregH has given you very good points on why there is a specific tool for a specific job. Additionally, any quality experienced tech that would repair the unit would be doing a further thorough leak check anyway because a good tech doesn't take the customer's word that it is the only leak...no offense intended. It's like telling a good doctor you have a sore throat. The doc's still going to find out for himself and your still going to pay to have your throat looked at before a remedy is prescribed.
