STOP Overthinking! – QA Short #204

In this short podcast from our Q&A series, Bryan answers a viewer question and implores you to STOP overthinking in the trade! He also shares a parable and some tips to help stop overthinking, especially if you're just starting out in the trade.

In many cases, the simplest assumption is the right one (this is called Occam's Razor). We can always start with the most obvious or simplest possible answer. We can become mindful of our tools, such as by making sure our seals are intact, and we become masters of the obvious.

Perfecting little things (and micro-tasks) can help you become more familiar with the tools you use and the equipment you work on, and you start to develop a bigger-picture understanding of your craft. Cleaning the equipment and organizing your tool bag goes a long way; you can unlock the ability to zoom out and spot mistakes that you otherwise wouldn't have thought of otherwise.

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

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
