A Complete Guide for Refrigerant Leak Detection!!!

Refrigerant is one of the significant attributes of a building. With time refrigerant can detect different faulty errors, and you can easily detect the proper cause behind it with the guide mentioned below. 

Let us look into a guide on how you can check the leak in the refrigerant that is causing trouble in everyday use. It is better to use the steps mentioned below for knowing how you can check the leak detection and check it on your own without calling out for professional assistance.

Step by step guide for refrigerant leak detection!!!

When it comes to detecting refrigerant due to leakage, some might feel that they might require a new one. However, sometimes correcting a simple error can help you with the fixing of the leakage. When you follow up a proper guide, you can certainly detect different problems and easily correct them.

Knowing how to operate a leak detector

Every manufacturer keeps in mind the requirement of knowledge regarding each operation of the refrigerant. You are provided with a manual guide with refrigerant regarding how to detect leakage or further operation of it for your convenience. A good operator is equally good at the good leak detector. Make sure you aren’t camping on the suspected leak with your meter. 

The newly introduced refrigerant automatically shifts to refrigerant concentrations and makes it look like there is no concentration. Using the probe, you can detect the refrigerant concentration easily. If looking for ease of detection, then a visible method like bubble solution to pinpoint the leak would be effective surely.

Sensor degradation can be caused due to heated diode, heated pentode, corona shield. Heated electrolyte or other methods that break down the sensor directly in the mainstream of refrigerant are harmful. If heat is the actual reason, then do not insert your sensor into the refrigerant stream that is mean of checking the meter. Practicing this might ruin the sensor, and that would require a quick replacement for the damage done. It is better to replace the sensor after 20 hours if not then make sure calibrated reference leak that the sensor can still sense a small concentration of refrigerant. You can also choose for the infrared leak detectors that look at gases in the refrigerant region in the infrared spectrum.

Start meter outside

Another step that you can practice is to start meter outside and let is self zero before entering the residence. Ensure your meter is good enough to detect the leakage and ensure that you use a calibrated reference. When you start the meter outside, it gives the meter a chance to zero itself without refrigerant exposure. 

Entering the vacant space

If you have ensured that meter is capable of detecting, then let it be self zero. Take a look into it over again and check if it notifies again if yes, then safely determine the refrigerant concentration that is in the space. For confirmation of the leak, presence makes sure every detection must be repeatable.

Shut off the HVAC system

To make sure that the blower is not running, the HVAC system must be shut off. Wait for 10 minutes for the settling of the concentration and leakage of the refrigerant. Once you have practiced it safely, then get into the indoor evaporator.  For further correction, you need to condensate drain fitting to avoid any heat.

Check condensate pan with your electronic leak detection tool.

If condensate pan picks up the refrigerant, then remove it and let it be self zero. Once again, take a look into the pan. If you notice the picking of the refrigerant, then it is clear that refrigerant leakage is present somewhere in the evaporator section. There is no noticeable damage in the coil itself, and you may need to call out professional assistance for correcting the issue with further detection.

Once you have checked the concentration, remove the evaporator door to expose the coil and mechanical connections. Now further look into all the mechanical connections by using a visible method such as bubble solution on the mechanical joints where the txv, equalizing tube, Schrader fitting, etc. are connected or capped.  

After all, the procedure practiced if you fail to locate any leak into the mechanical joint then condemning the coil as the leaker wouldn’t be incorrect. 

So, by following all the mentioned above steps, you can check out the leakage and easily operate your leak detector to normal functioning. Ensure you keep a check on the leak detector by regularly checking it against the calibrated reference leak. With a regular check, you can determine if the tools are in working or not. Ensure you are not replacing any part of the refrigerant until it is proved that leakage is caused in it. You have to be aware of the detection for saving on the cost of replacement and simply repair the part where the faulty error is detected.

The summary

In summary, we can conclude to an aspect that it is appropriate to make use of the proper leak detector tool for determining the cause. With time you can probably require repair and complete check of refrigerant for making it work normal for the long term. It is better to do pre-check of the device with different tools, and if you find it complex to do it on your own, you can make a visit or simply ask for expert assistance.
