![]() “We don’t have callbacks, and it saves our customers a lot of money,” he said. in South Elgin, Illinois, said he’s had great success using leak-stop agents when it comes to very small leaks. “If the leak is accessible and easy to repair, I always do it the conventional way, but many times there are leaks that can’t be located or are in inaccessible places, and this stuff becomes a lifesaver.” “I’ve had it in some systems for five years now, and I’ve not had a call back on a leak,” he said. Kevin Wood, owner of Holly Wood Air in Visalia, California, said he has used leak-stop agents for the past five years and has found that they work great for hard-to-find leaks or those that are in the middle of coils. should follow Canada and have a policy of zero leak tolerance.” “We can do much better than we are doing. ![]() “We need higher test pressures, longer wait times, and advanced installation practices if we are to achieve leak-free systems,” he said. He added that doing it right the first time takes less time than repairing a leak after a problem shows itself. “However, these products should not be allowed as permanent repairs.” “I do think there is something to be said for additives that could seal small leaks, since it is almost impossible to be 100 percent leak-free, even for the best of the best,” he said. Having said that, Baker stressed that this does not mean the additives don’t have a place, adding they could work well in limited, preventive roles. There is a $50,000 fine for noncompliance, an additional $1,000-a-day fine from the day of the conviction up to prosecution, and/or six months in jail.” “Other than that, all leaks must be repaired immediately. “That’s why these products are not the correct answer and why in Manitoba and Winnipeg they are considered temporary and can only be added to a known leak-free system before a leak develops or after a leak has been repaired,” he said. There is never a replacement for clean, dry, and tight.”īaker agreed with Kokinda that most leaks occur because of improper installation procedures. “Furthermore, we all should understand these are not permanent repair products and, therefore, have limited use and specific uses. “It always comes down to using a trusted product,” he said. in Winnipeg, Manitoba, Canada, said it’s unfair to lump all leak-stop products together, as some have much different formulations than others. Brian Baker, president of Custom Vac Ltd. The 35 percent leak rate the EPA allows for these types of systems is ridiculous.”ĭ. “If the EPA got its act together, it would not let systems like this be continuously topped off. “Unfortunately, that is not always the case,” he said. He cited Kokinda’s story as a perfect example of why systems must be properly brazed or crimped, pressure tested, and evacuated. “The only thing that should ever be in a system is pure virgin refrigerant and oil,” he said.
