Last week, we briefly looked at the spec sheet of a gauge manifold. All things considered, it was quite short; we only had to worry about the refrigerant types, pressure ranges, and hose diameters. However, manometers’ spec sheets are quite a bit longer than gauge manifolds’ because they have resolution and accuracy specs, among other […]

In a previous article, I talked about wiring permanent split capacitor (PSC) condenser fan motors. While researching the topic, I realized that there isn’t as much information available on condenser motors as there is on their counterpart—the indoor blower motor. I had never really given it much thought, as I assumed that the condenser motor […]

The original tools of the trade were all analog: electrical meters, gauges, and even manometers (Magnehelic, anyone?). However, digital tools have also become a staple of the skilled trades—where would most of us be without digital multimeters? And then probes also joined the fray with the rapid improvements to smartphone technology over the last 15–20 […]

 Don Gillis and Dr. Chuck Allgood from Chemours join the show to discuss their new easy as “1,2,3” branding around the A2L refrigerants R454A, R454B, and R454C. They explain that A2Ls are not actually flammable like hydrocarbons; they are just mildly combustible with much lower burning velocity and energy than propane or butane. The […]

In this podcast episode, Bryan and Nathan discuss balancing evaporators in a multi-coil circuit. They specifically focus on using the TXV to do so. When we say “balancing evaporators” in a multi-coil circuit, we're referring to the temperature of the air leaving the system; we are worried about the air keeping the product cool in […]

In this live podcast episode, we have a fun conversation talking with Nathan Orr and Kevin Compass about grocery refrigeration. The most common types of calls are those where the machine is “not making temp.” Usually, the cases can't maintain temperature due to frozen evaporator coils or backed-up drains. On low-temperature/freezer applications, we must rely […]
