HVAC Refrigeration Repair App

About HVAC Refrigeration Repair App

R-Pro is the complete field app for air-conditioning and refrigeration technicians. Diagnose the fault, keep a record for every customer, and bill the job — in 14 languages, with reference and records that work offline.

━ DIAGNOSE & FIX ━ • Real-measurement diagnosis — enter gauge & temperature readings; R-Pro computes superheat/subcooling and tells you if the charge, airflow or metering device is the problem. No guessing. • Symptom search — describe what you see or hear in plain words; get probable causes ranked with repair steps. • Error codes — thousands of codes across 62 brands, each with meaning and the fix. • Manuals & refrigerant tables — maker manuals, thermostat/controller manual, P-T data for 108 refrigerants. • Inspection checklists & refrigeration fundamentals.

━ RECORD & RUN YOUR BUSINESS ━ • Customer & equipment history — every site & unit on record: what you fixed, when, parts, refrigerant. Arrive anywhere and see its full history. • Voice to work log — speak while you work; it becomes a structured job report. No typing on a ladder. • Scan to capture — nameplate, business card or receipt into data in seconds. • Quotes, invoices & receipts — issue from the field. • Accounting — revenue, expenses & supplier purchases into net profit. • Alarms & reminders; private field know-how notes.

━ ALSO ON YOUR OFFICE PC (ERP) ━ What you logged on the phone in the field is already on the office computer. Nothing to install — open r-pro-erp.web.app in your PC browser and sign in with the same account as the app. • Issue quotes and invoices on a full screen; review customer & equipment history • Turn revenue, expenses and supplier purchases into a monthly ledger • Written on the phone, finished on the PC — no exporting, no re-typing
