The Leak Stops Here: Should You Use Leak Stop Agents?

Leak stop agent is a blend of chemicals that are sometimes used to seal small leaks in air conditioners.

The chemicals, once activated by moisture, solidify and form a permanent patch. Primarily, the extreme temperature differential at the leak point causes condensation. This “moisture” activates the chemical.

There are two trains of thought when it comes to the use of leak stop agents in your air conditioner. Some people have used them successfully for years and consider them practical and cost-effective ways to seal small, hard-to-find leaks. Other contractors feel strongly that leak stop agents are harmful to an AC unit and all leaks should be fixed the conventional way, by a person. Read on for Romaniuk’s guide to the pros and cons of leak stop agents.

Pros To Using Leak Stop Agents

The main benefit of leak stop agents is that they can seal hard to find or not easily accessible leaks. If a leak is in the middle of the coils or is otherwise hard to get at, leak stop agents offer a more cost-effective solution, rather than having to pull the entire unit apart.

Sometimes, a leak is so small it can’t even be located! In times like these, leak stop agents can be beneficial.

"Ultimately, you can’t lump all leak stop agents together, as there are many different formulas."

Cons To Using Leak Stop Agents

There are a few issues that arise with leak stop agents. The first is that the chemicals used are not always approved by compressor manufacturers. This means that using them could void your warranty on your AC unit.

The second concern is safety. The refrigerant is a dangerous substance and is meant to stay confined within your AC unit. When it comes to dealing with refrigerant, most people would prefer to make sure the leak is found and repaired correctly, rather than leaving it up to a chemical to fix the problem.

Yay Or Nay?

Ultimately, you can’t lump all leak stop agents together, as there are many different formulas. What’s important to keep in mind is that these products should not be considered a permanent repair. They have limited and specific uses. There is something to be said for additives that can seal small leaks, but if you have added a leak stop agent, you’ll want to make sure you contact an air conditioning technician to come in and fix the problem permanently.
