Featured this month is NCI’s Fan Laws training. Using fan laws is an essential part of adjusting system airflow in commercial equipment with belt-drive motors. In this module we discuss the three basic fan laws and how to apply them to a commercial HVAC system.

For those of you looking for more than in-person training, these online courses focus on several areas of concentration:

  • NCI-specific training on testing and measuring
  • Exclusive NCI soft skills and business training
  • Basic HVAC training to help prepare students for various NATE certifications and more.

There’s An App for That …

Mobile apps for HVAC contractors are everywhere. Do they provide big bang for the buck (or download time)? Not necessarily. NCI’s David Richardson has found a number that make great sense for the Performance-Based Contracting’ community and we present those here.

This month we highlight one from DesignStein, LLC called SuperCool HVAC App. This app includes a duct sizing and layout calculator, superheat and subcooling charging calculator, a compressor windings troubleshooting guide, plus a converter for everything HVAC.

It even has heating and cooling airflow troubleshooting built in.

This is a free app available in both the Google App and Apple App stores. Check them out and let us know if you think ‘the juice is worth the squeeze.’
