This tech tip about humidity control, particularly as it relates to VRF systems and others that use inverter technology, is a companion piece to a podcast episode with Roman Baugh. You can listen to that podcast episode HERE. Those of you who work in humid climates and install or repair ductless systems are probably well […]

Every once in a while, especially on humid days, you’ll sit on an airplane waiting for takeoff and see fog pouring from the ceiling vents like a low-budget concert. Someone always panics and asks if something’s on fire. It’s not smoke—it’s condensation. You’re looking at thermodynamics and psychrometrics in action. So, why does it happen, […]

I admit it, I'm a sauna guy now. The ones at the gym are pretty gross, so I got a small one at home because I guess I’ve missed sitting in attics or something. If you’ve ever sat in a traditional sauna, you know the drill: the heat’s already intense, and then you or someone […]

 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 […]
