How can I find where my AC is leaking?

How do I find a leak in my AC vacuum?
You can and should pull a vacuum, look at the reading on the manifold gauge set, let it sit for some amount of time (overnight is best), and see if the vacuum reading drops, because if it does, there’s a leak somewhere. But the vacuum itself is really almost no help in finding the leak.
How do I find a leak in my AC dye?
Using Brilliant UV leak detector dye is easy and effective. Simply inject Brilliant into the system, shine a blacklight onto the hoses, and look for fluorescent markers that indicate a leak. Once the leak is discovered, you may be able to fix it using AC SmartSeal or AC SmartSeal External to create a permanent seal.
Will pulling a vacuum on an AC system help determine if you have a leak?

Can a leaking air conditioner make you sick?
The coolant leaking from an aircon rapidly evaporates into a gas. This gas is lethal and can cause nausea, and in some cases, even asphyxiation. The leaked gas can also lead to skin irritation and dryness as well as increased heart rate. Continued exposure to this gas can lead to life-threatening medical conditions.
