As we get older, our understanding of the difference between good and bad—right and wrong—evolves. This understanding often first takes on the form of playing cops and robbers or superheroes and bad guys in our childhood. As we grow, especially as we navigate adolescence and adulthood, we apply the labels “good” and “bad” (or “friend” […]

In HVAC, we have a few infamous indoor air quality monsters that bring terror to our customers’ homes—gases, particles, and organisms that wreak havoc on indoor air quality (and may contribute to moderate to severe health problems). The big one is carbon monoxide (CO), which we all know is deadly. Although not deadly by itself, […]

Namely, people install it right at the condensing unit. (OK, it isn't that big of a deal, but I needed some dramatic emphasis.) Installing it at the indoor […]

 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 […]
