In this episode of the Spidey Sense series, Bryan and Bert dive deep into the art of refrigerant leak detection, sharing their wealth of experience and practical tips for HVAC technicians. They emphasize the importance of using one's senses and observation skills before relying solely on electronic tools, highlighting how this "Spidey Sense" approach is a hallmark of senior-level expertise in the field.

Visual and tactile cues, including warm suction lines, frosted components, and signs of oil, are vital. Different symptoms point to specific kinds of leaks and various scenarios, so you need to understand the behavior of the system.

Bryan and Bert also discuss the strategic application of soap bubbles, electronic leak detectors, and nitrogen for pressurization. Each method has limitations, and you'll need to know when to employ them for maximum effectiveness. When detecting leaks, consider recent home renovations or equipment vibrations that might contribute to leaks.

Topics covered in the podcast include:

Visual and tactile cues for identifying potential refrigerant leaks The debate on frosted lines as indicators of low refrigerant charge Proper use of electronic leak detectors and their limitations Strategic application of soap bubbles in leak detection The importance of checking common leak locations (e.g., flare fittings, evaporator coils) Considerations for leak detection in newly installed or recently serviced systems The role of nitrogen in leak detection for systems with very low refrigerant charge Estimating the severity of a leak based on system pressure and charge level The pros and cons of isolation tests for line set leaks Techniques for detecting very small, slow leaks that might not show up in pressure tests The potential use of ultrasonic leak detection tools The importance of thorough inspection and patience in the leak detection process
