This is why AC stop leak sealers seal small pinholes – by reacting to the condensation caused by the temperature around the pinhole. You must understand that AC stop leak sealers react to water, and when they do that, they become hard. An AC stop leak sealer will also reduce the efficiency of your AC by up to 10%. They can clog important parts like the expansion valve, evaporator, or condenser. AC stop leak sealers are bad for your AC system. RELATED: How Much Does an AC Recharge Cost?

If you visit a workshop and notice that a leak sealant is present in the AC system, the system must be flushed before.It is often more of a temporary solution than a permanent one because of the high pressure within the AC system.It is not proven that they can seal around O-rings and shaft seals, which are the most common leak places.This can cause the efficiency to be reduced by up to 10%. They can disturb the flow and pressure of the AC system.This can cause significant additional repair costs.

They can clog the expansion valve, the AC evaporator/condenser as well as other parts.

In my opinion, it is much better, and also probably cheaper in the long run, to repair a leak properly. Here are the advantages and disadvantages of using an AC leak sealant, so you can ask yourself if it is worth it. There are a lot of different opinions when it comes to AC leak sealing.

When reacting to the leak location’s temperature, it will become a hard sealer instead of a liquid, and therefore it will stop the leak.Įven if you may think so, AC leak sealers are not new on the market. How much does AC Stop Leak cost? What is an AC leak sealer?Īn AC leak sealer is a product that works by reacting to the temperature when the refrigerant is flowing out from a pinhole in the AC pipe.
