When we think of air leakage, a few common scenarios probably come to mind: disconnected ducts at connections, poorly sealed connections, and air leakage around vents are ones we’ve mentioned quite a bit in tech tips and videos over the years. However, there are a few that we haven’t really talked about, particularly for fan […]

The condensate drain is the source of many a service call in Florida. A lot of the time, the problem is just a clogged drain; bacterial zoogloea (drain snot) loves humidity, and the all-aluminum coils don’t do us any favors. Other times, there are some clear drain design or installation flaws that present hazards to […]

This tech tip about tandem compressors was inspired by the recent HVAC School podcast episode with the Copeland team. You can listen to that podcast episode HERE. One compressor is great, but how about two in the same circuit? Or three? We see multiple compressors in rack refrigeration circuits, but the concept isn’t as common […]

  Chris Stephens from HVACR Videos joins us to talk about his experiences with and perspective on R290 (propane) refrigerant in restaurant refrigeration. Chris sees R290 propane on a daily basis, and his perspective as a tech differs from that of an R290 equipment manufacturer. While the temperature sensitivity contributes to flammability, R290 is also […]

Chris Stevens from HVACR Videos on YouTube comes onto the podcast and talks about some refrigeration temperature controls basics. You can check out his YouTube channel HERE. Although we have temperature controls in HVAC work, we will see slightly different ones in refrigeration work. The biggest difference is really the temperature itself; we're attempting to […]
