Nortek Global HVAC Launches Micro-Channel Charge Calculation Website

New tool makes charging Micro-Channel and mixed coil systems simpler.

St. Louis, October 25, 2017 — Nortek Global HVAC has introduced an all-new Charge Calculator website. This new tool makes charging Micro-Channel systems and mixed coil systems simpler for the installing contractor or servicer.

The tool takes a contractor through the charging process step-by-step – from calculating the correct base charge to determining whether refrigerant needs to be added or taken out of the system. The measurements contractors take during these steps can help paint a complete picture of the unit. In addition to the charging benefits, this tool is a helpful refrigeration system diagnostic tool. The ability to diagnose issues using the tool can save contractors time on the phone with technical support.

This online tool joins a host of other resources created by Nortek Global HVAC aimed at making the installation and service of Micro-Channel systems simpler. Other tools include the Quick Reference Data sheet, which comes with the equipment and is available on Nortek Global HVAC’s online literature library, and an educational Micro-Channel coil website.

The Charge Calculator is available for free online – no fees or app required. All you need is a zip code and a valid email address. Visit to access the tool. Those who need step-by-step instructions on how to use the tool, can visit EdgeTek and take our charge calculator training course.
