HVAC Troubleshooting Apps
HVACR Check & Charge
HVAC Check & Charge is a mobile diagnostic tool designed to help technicians evaluate system performance and refrigerant charge directly in the field. It reduces reliance on manual charts and calculations, helping techs diagnose issues faster and more consistently during service calls.
The app is especially useful for troubleshooting cooling performance and ensuring systems are charged correctly according to manufacturer guidelines.
Best suited for HVAC technicians who regularly diagnose refrigerant charge and want faster, more accurate system checks in the field.
Key features
Superheat and subcooling calculations based on live inputs
Guided refrigerant charging support
System performance checks for common HVAC configurations
Mobile-friendly interface designed for on-site use
Pros
- Improves accuracy during refrigerant charging
- Reduces manual calculations in the field
- Backed by a well-known HVAC manufacturer
Cons
- Most useful when paired with compatible tools
- Narrow focus on diagnostics only
- Limited use outside service work
“Great app, my entire shop uses it. But the tolerances for what's a correct charge are a bit off. For subcool, only 1 degree off is all I'll allow. Would be nice if I could adjust what is considered a correct charge in settings, but that may just be me. Other then that, has all the refrigerants even 454B as it came out and works great.”
