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.

Ratings and Reviews
Best Helper Ever
I never thought I’d see the day I incorporated my phone into refrigerant work, but here I am, and so far I’m shocked it took me this long. The CheckCharge app has been a great new partner. No longer do I have to carry around or look up charts for every refrigerant I encounter. Now I can quickly select the refrigerant I’m working with, choose the charging method I’m going to be using, and then input my temperatures and pressures. Once I’ve put all my data in the app I can quickly see where I’m at. This app won’t put up your tools or button the system back up, but it does make things easier and faster which is fantastic.
Will never change
From the first time I opened this App, I have loved it, on my iPhone, in my iPad nothing else will do. It has never let me down, easy to read, three this you’ll see add, remove and correct charge. Those 3 things will never change, and neither will I.
Most accurate charge with 410-r22
Been using this app to get the perfect charge for r410a and r22 for 5 years now absolutely love this app and will definitely have all my technicians use this app for more years to come
It’s best used for superheat
Sub cooling is always 10degrees on systems in Ohio so I don’t use it for sub cooling
