HVAC Check & Charge for iOS

The HVAC Check & Charge app is a free educational tool designed specifically for HVACR technicians. It assists users in calculating the correct refrigerant charge for air conditioning and refrigeration systems under various operating conditions. With real-time guidance, the app helps ensure that technicians can optimize system performance effectively.

Users can select from three operational modes: Superheat, Subcooling, and Airflow, depending on their specific needs. The Superheat mode is particularly beneficial for central air conditioning and similar systems, allowing users to input necessary temperature and load parameters to achieve accurate refrigerant charges. This functionality supports technicians in making informed decisions to maintain system efficiency and reliability.
