Leading Causes for Leaks

Shrader valves, heat pump accumulators, and capillary tubes are the three leading parts that cause this problem to occur. We’re going to lay out in more detail what each part does, and why it can cause the leak.

Every unit has a similar structure to it, and within that is the shrader valve. This is where you will hear the coolant leak, and the need to replace this part is extremely important. The shrader valve allows technicians to check pressures or charge the system, and if it is indeed this problem, then you are in luck, as it is traditionally one of the easiest to fix.

Another leading cause is when the heat pump accumulator begins to rust, and therefore holes begin to appear, where Freon or refrigerant can leak out. This is not an easy fix, as the entire system needs to be recovered and replaced, and a new accumulator installed. The best way to prevent this from happening is to apply a rust preventing paint to the accumulator, thus preventing the steel from rusting and creating cavities.

Capillary tubes inside the evaporator coil can also get small fissures in them, because they are constantly rubbing together due to the system running, and the friction that occurs can ultimately cause these little holes. Fixing capillary tubes is as easy as cutting the affected area and soldering a larger piece of copper tubing over this capillary tube.

Depending on how old your unit is, if you’re experiencing a refrigerant leak, it might be in your best interest to look into getting an entirely new system. While the fix might be simple, it ultimately will happen again because the unit features older parts that have worn down through repeated use. The last thing you want is to have a system breaking down because of a leak, because not only does that mean you will not be cooled in your own home, you’re also sending out hazardous materials into the environment that can cause even more problems.

Contact an experienced AC repair company if you hear the hissing of a refrigerant leak. While some of the problems may be addressed by the home owner, we highly suggest having an expert give the system an entire look. A leak may lead to other problems for you, and you may not be able to spot them if you don’t have the eye for it. Don’t wait to have the issue resolved, because the cost can increase substantially the longer that you wait. We’re ready to assist you in whatever way we can to get your system running again the way you need it to.
