CapCheck HVAC is a fast, field-focused run capacitor calculator designed for trained HVAC/R technicians.
Calculate dual run and single run capacitor values using live voltage and amperage readings directly in the field.
Features:
• Dual run capacitor calculations
• Single run capacitor calculations
• Under-load live testing calculations
• Automatic tolerance and deviation analysis
• Fast technician-focused workflow
• Light and dark themes
• Large easy-to-read results
• Built for field service use
• Simple and streamlined interface
CapCheck HVAC helps technicians quickly determine capacitor performance using measured operating values instead of relying solely on disconnected capacitance readings.
Calculation modes include:
• Dual Run Capacitor
• Single Run Capacitor
The app compares calculated microfarad values against rated capacitor values and displays:
• Calculated µF
• Deviation percentage
• Allowed tolerance range
• GOOD / LOW / HIGH status results
CapCheck HVAC is designed to remain fast and simple for real-world HVAC service environments.
