HVAC PT Chart Toolkit is an offline field workspace for technicians working on air conditioners, refrigeration systems, cold rooms, chillers and freezers. It is designed for paid, professional use: no account, no ads, no subscription and no server connection. Core tools: • Refrigerant PT charts for common refrigerants • Pressure to saturation temperature and temperature to pressure lookup • Superheat and subcooling calculators • Unit conversion for pressure, temperature, length, mass/charge, current/power, capacitance/resistance and vacuum/pressure • Offline fault code lookup • Symptom-based diagnostic checklists • Repair records, quotes, customer signatures and photos • PDF and image work order export • English and Simplified Chinese interface • Light, dark and system appearance modes Field workflow: 1. Search a refrigerant, fault code or tool 2. Calculate PT, superheat or subcooling 3. Follow a repair checklist 4. Add readings, photos, parts and labor 5. Capture a signature 6. Export a PDF or image repair order This app does not attempt to automatically diagnose equipment. Results are for field reference only and should be checked against the equipment nameplate, manufacturer documentation and actual site conditions. Electrical, high-pressure and flammable refrigerant work should be performed by qualified technicians following applicable safety rules. All data is stored locally on your device. Repair records are not uploaded. The app can be used in airplane mode.
