How to FIND a REFRIGERANT LEAK in an AC Unit with an Electronic Leak Detector!

Summary

In this video, viewers are shown how to locate a refrigerant leak in an air conditioning system. The process begins with inspecting the indoor evaporator coil and using an electronic leak detector to identify potential leak areas. The tool's probe is moved slowly to detect leaks, with particular attention to joints and connections. Once a leak is suspected, a bubble leak detector is used to pinpoint the exact location by observing the formation of tiny bubbles. The video highlights the importance of using both tools for accurate detection, ensuring a thorough method for finding and fixing refrigerant leaks.

Takeaways

• 😀 The script demonstrates how to detect a leak in an air conditioning system using both an electronic leak detector and a bubble leak detector.
• 😀 Always power up the electronic leak detector for at least 30 seconds before using it to ensure accurate readings.
• 😀 Move the electronic leak detector probe slowly and carefully around the suspected leak areas to get the best results.
• 😀 The electronic leak detector will alert you when it detects a refrigerant leak, usually with a sound or light.
• 😀 After using the electronic leak detector, verify the leak locations with a bubble leak detector to pinpoint the exact spot.
• 😀 The bubble leak detector creates tiny bubbles that foam up at the site of the leak, which helps confirm the leak’s location.
• 😀 The leak detection process involves checking both the front and back of the distributor tubes where they connect to the evaporator coil.
• 😀 The video shows that leaks were found in two key areas: at the front and back of the distributor tubes where they meet the evaporator coil.
• 😀 Using both tools together—electronic leak detection and bubble leak detection—ensures an accurate and reliable leak diagnosis.
• 😀 The video encourages viewers to check the description for links to the tools used and support the channel via Patreon for more educational content.
• 😀 The process demonstrated in the video is essential for HVAC professionals to accurately detect refrigerant leaks and make effective repairs.

Q & A

What is the main focus of this video?

The main focus of the video is to demonstrate how to find a refrigerant leak in an air conditioning system, specifically at the indoor evaporator coil.

What tools are used to detect refrigerant leaks in the video?

The video uses two tools to detect refrigerant leaks: an electronic leak detector (Back Rack Informant) and a bubble leak detector.

Why is the Back Rack Informant powered up for at least 30 seconds before use?

The Back Rack Informant is powered up for at least 30 seconds to ensure it is calibrated and ready to accurately detect refrigerant leaks.

How does the electronic leak detector work in this video?

The electronic leak detector is used by slowly moving the probe around the evaporator coil. It beeps when it detects the presence of refrigerant, indicating a potential leak.

Where were the leaks detected in the evaporator coil?

Leaks were detected near the front of the evaporator coil and at the back, where the distributor tubes meet the evaporator coil.

How is the location of the leaks confirmed in the video?

The location of the leaks is confirmed using the bubble leak detector, which creates foam bubbles at the leak sites when it comes into contact with refrigerant.

What does the bubble leak detector show when it detects a leak?

The bubble leak detector shows tiny bubbles or foam forming at the leak site, indicating the exact location of the refrigerant leak.

Why is it important to use both an electronic leak detector and a bubble leak detector?

Using both tools is important because the electronic leak detector helps locate the general area of the leak, while the bubble leak detector helps pinpoint the exact location by visually showing the leak.

What additional resources are offered to viewers of the channel?
