About this app

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.

Advertising & Privacy:
CapCheck HVAC is supported through advertisements with an optional one-time purchase to remove ads. The app does not require accounts and does not store or upload capacitor readings entered into the calculator.

Important:
CapCheck HVAC is intended for trained HVAC/R technicians. Live electrical testing can be dangerous. Always follow proper safety procedures, manufacturer documentation, and applicable codes.
