            I'd like to give special thanks to Steve Rogers from TEC for helping write this tech tip about ECM blower fan watt draw and sharing some helpful visuals. Thanks, Steve! ACCA Standard 310 introduced a grading protocol for HVAC systems. While HVAC practitioners won’t be the ones carrying out the tasks laid out in Standard […]

            I'd like to give a special thanks to Tony Gonzalez from Fieldpiece for providing technical guidance about the SC680's power measurement capabilities, as well as VAC and AAC measurements on ECMs. You can learn more about the SC680 and other electrical meters on Fieldpiece's website. We’ve talked through specifications, applications, and features for a few […]

            This tech tip was submitted by Tim De Stasio. He originally published it on his website, which you can visit HERE. Thanks, Tim! Winning takes strategy and the right information. The HVAC business is no different.  But what information should we collect, even pay for, to get better and win? What if these widely accepted […]

            Capacitors are traditionally tested with a capacitance meter (commonly found as a function within a multimeter), with the component taken entirely out of the circuit. “Bench testing,” as this method is referred to, is hands-down the safest method of checking capacitance in microfarads. All other methods require the capacitor to be wired into the circuit […]

            In a previous article, we covered the standard way to check capacitors under load. I am now going to give you an even easier test. A properly functioning PSC (permanent split capacitor) or CSCR (capacitor start capacitor run) motor should have a power factor of very close to 1 if they have a properly sized […]

             In this short podcast episode, Bryan talks about EER (Energy Efficiency Ratio) and SEER (Seasonal Energy Efficiency Ratio) and how to calculate EER in the field. EER and SEER are ratings that we often see on equipment (as are SEER2 and EER2) based on a ratio of an output to an input. Whereas coefficient […]

             Bryan Orr and Steve Rogers dive deep into measuring power consumption in HVAC blower motors, particularly focusing on the differences between PSC (Permanent Split Capacitor) and ECM (Electronically Commutated Motor) technologies. The discussion stems from a question raised at an educators' conference about the accuracy of clamp-on meters in measuring blower motor watt draw, […]
