While some folks use secondhand anecdotes of lousy leak sealant experiences to support their arguments against internal sealants, the reality is that modern leak sealants like AC SmartSeal are specially designed and manufactured to be perfectly safe and effective for use in air conditioning and refrigeration systems.
Do leak sealers work?
The answer to this question is yes, radiator sealants really do work. However, they are not a miracle solution, and are only good for a temporary fix. Even so-called “permanent” sealants will only last for months, not years. A good radiator sealant–also called a stop-leak–can seal all kinds of cooling system leaks.

What happens when Freon leaks from air conditioner?
When there is a slow leak, there’s still enough refrigerant in the system that it can refrigerate it can do some cooling. However, it will not be operating properly and it will cause the pressure to be too low for the coil inside. This causes the coil to “freeze” and eventually stop the air conditioner from working.
How long does it take for Freon to leak out?
Depending on the appliance’s age, the size of the hole, and the amount of coolant in the unit, it can take 30 minutes to six hours for Freon to leak out of an AC or refrigerator.
The refrigeration system that houses freon in your AC is a closed system. With a closed system, none of the gas or fluid within the system has a chance of escaping, unless there’s a leak.
Can you smell Freon leak in car?
Freon usually travels through closed copper coils in an AC unit, but these coils can crack and result in an AC coolant leak. A freon leak will produce a smell between sweet and chloroform. Freon leaks can be toxic.
Where do most Freon leaks occur?
Freon leaks are typically found at the schrader valve, valve cores, evaporator coil, copper lines, “U” connectors, weld joints, electrical connection to the compressor body, or the copper tubing. Most of the time, the leak will usually occur in the evaporator coil.
Where can Freon leak from in a car?

How long does Freon last in a car?

How do you know if your car is leaking Freon?
Visible Refrigerant Leaks
You can tell that it’s freon if it looks like thin grease in liquid state. Drivers will often find it around the compressor, lines, or inside the cabin or pooled underneath the vehicle. Eventually the loss of refrigerant will cause the A/C system to no longer work.
