About HVAC Check & Charge
Instant mobile refrigerant charge calculator for HVACR applications.
The HVAC Check & Charge™ mobile app from Emerson Climate Technologies provides an on-site refrigerant charge calculator for air conditioning applications. Based on historic sliding cardboard charge calculators, this app allows contractors to easily calculate correct system refrigerant charge for R-22 or R-410A. Contractors can simply choose Subcooling, Superheat, 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.
• Superheat Calculator (non TXV)
• Subcooling Calculator (TXV)
• Airflow Calculator
• For use with R-22 or R-410A
Assists with calculating proper system refrigerant charge based on operating conditions.

Works very well. Wish it had r22 replacement calculations. Wider range on values would make this app perfect

I would give it 5 if the wet bulb not limited to 76°. Should be up to 85°. Please fix it..

Wish I could get values outside recommended operating range. Not uncommon to have an r22 suction below 58 psig(yes I know it's undercharged but would still be nice to input the numbers I'm getting ). Your not always going to have ideal conditions to check a unit.

Limited to short and skipping range inputs. Also gives different SH&SC Calculations then my SMAN, recommending increasing charge when SMAN spot on.

Like app. Easy to use. But needs 1 degree increments on wet bulb and on condensor dry bulb adjustments without any caps on settings. The field does not ever have perfect world conditions.
