Instant mobile refrigerant charge calculator for HVACR applications. The HVACR Check & Charge™ mobile app from Emerson Climate Technologies provides an on-site refrigerant charge calculator for air conditioning and refrigeration applications. Based on historic sliding cardboard charge calculators, this app allows contractors to easily calculate the correct system refrigerant charge for R-22, R-410A, R-32, R-407C, R-134a, R-452B, R-454B, R-438A, R-422B, R-427A, R-421A, R-404A, R-290, R-449A, R-448A, and R-407A. Contractors can simply choose Superheat, Subcooling, or Airflow and enter the specified system temperatures along with the latent and sensible environmental loads. These values are then used to determine the proper system charge and whether the charge amount needs to be altered based on these conditions. • AC & Refrigeration Systems • Superheat Calculator (non-TXV) • Subcooling Calculator (TXV) • Airflow Calculator • PT Charts (Pressure / Temperature) • Find a Superheat target using psychometric calculations • For use with R-22, R-410A, R-32, R-407C, R-134a, R-452B, R-454B, R-438A, R-422B, R-427A, R-421A, R-404A, R-290, R-449A, R-448A, and R-407A • Imperial and Metric Support Assists with calculating proper system refrigerant charge based on operating conditions.

App works and runs great! Really nice way to show and educate customers about correct refrigerant charge via the graph. This app is a must for running early spring maintenances and make sure you’ve got the perfect charge in a system.

Been in the HVAC industry for several years now. Learned of this app several months ago. It’s great to have especially when the manufacturer doesn’t provide any pressure/temp/superheat/subcooling charts on the equipment.

Check in charge of app has been very helpful over the years.
