UNITED STATES – Emerson Climate Technologies, Inc., a business of Emerson has reached the milestone of 100,000 downloads on its HVAC Check & Charge™ mobile app, making it the company’s most popular app to date.

The HVAC Check & Charge mobile app earned an honorable mention in the 2014 AHR Expo awards. IT Business Canada has also recognized the app as one of the top 10 apps for skilled trades.

“The app was designed to allow contractors to perform their jobs quicker,” declared Karl Zellmer, vice president of sales, Emerson Climate Technologies Inc., Air Conditioning business. “It’s a great tool for busy contractors, and it’s a good replacement for the old sliding charge calculators, so to see that it has reached 100,000 downloads shows us that it’s doing everything that we hoped it would.”

The HVAC Check & Charge app encompasses an on-site refrigerant charge calculator for air conditioning applications. The app enables contractors to easily calculate the correct system refrigerant charge for R-22 or R-410A.

To use the app, contractors must choose between subcooling, superheat or airflow and enter the specified system temperatures along with the latent sensible environment loads. These settings determine the proper system charge and whether the charge amount must be altered based on the given conditions.

The HVAC Check & Charge mobile app is just one part of the Emerson Climate Technologies HVACR Mobile Toolbox. Designed to give HVACR contractors on-the-go access to tools and resources that will help them do their jobs rapidly and more profitably, the Mobile Toolbox currently includes many other HVAC contractor apps which are available for free download at EmersonClimate.com/mobileapps.
