This article is not a full lesson on making a flare, but it will give you some best practices to make a flare that doesn't leak. First off, we need to clarify that very few unitary manufacturers use flares anymore. You will most often find flares on ductless and VRF/VRV systems and in refrigeration. A […]

This article includes significant contributions from Neil Comparetto and Brian Chadwick, both of whom are HVAC technicians in Virginia. Brian is also the owner of Chadwick Air, and Neil is a co-owner of Comparetto Comfort Solutions and a longtime contributor to HVAC School. Thanks, guys!

This tech tip was written by experienced tech and VRV specialist Ryan Findley. Thanks, Ryan. This is a quick overview, not a substitute for taking proper manufacturer training.   This tech tip is geared towards the mechanic who is fairly new to VRV systems. As with anything, before we harness the ability to install or […]

I hear many techs complain about the finicky and ineffective nature of electronic leak detection. So much so that some claim that it is a waste of time altogether. We recently located a leak inside the fins of a ductless evaporator coil—pinpointed to an exact spot—using an electronic leak detector. For demonstration purposes, we took […]

  Cleaning ductless systems is critical… and a pain.. Rather than just telling you how we do it let me show you some of the key points. This video demonstrates cleaning and testing a ductless system including pulling the blower wheel and washing the evaporator with a bib kit.   I also wrote a process for […]

  In this short podcast episode, Bryan dives into soft start & solar technology, which often work together. He also talks about how we can install ductless systems in homes that rely on solar power. Soft starts are NOT hard starts. Hard starts add more current to the start (auxiliary) winding, which creates a stronger […]
