Charge Calculator
A scratch built web application that allows HVAC contactors to analyze high-tech HVAC systems in the field in real time.
Project Overview
Nortek Global HVAC’s latest heating and cooling machines operate with more longevity and less energy usage than ever before. However, these advancements come at a price. These new machines are very particular about the amount of coolant they need to work correctly; too little and they don’t function well, and too much is an expensive waste. Nortek Global HVAC needed a solution that makes these machines easier to service for contractors that are not yet up to speed on the new technology.
In addition to requiring extreme precision, the contractors who service these machines often work on the road and travel on a regular basis. They needed an efficient way to connect remotely from a variety of platforms.
I led the project to create and develop a custom application that took Nortek HVAC's patented engineering algorithms and made them available to contractors in a responsive web app. This applications, called ‘Charge Calculator’, allowed contractors to troubleshoot and analyze these high-tech systems much more easily, thereby providing valuable service to their customers and maintaining the high quality reputation of the Nortek brand.
Business Outcomes
The pilot application was met with enthusiastic approval and allows contractors to more effectively service HVAC machines, with greater speed, more accuracy, and less waste.
Custom logging of user behaviour provides crucial usage feedback to the client for further optimizing subsequent generations of the application.
