HVAC PlateReader Pro

HVAC PlateReader Pro is an AI-powered field technician copilot purpose-built for residential and commercial HVAC, refrigeration, plumbing, and electrical mechanical contractors. By taking a simple photo of a worn, faded, or rotated equipment rating nameplate, an LED error-code display, or control wiring, technicians instantly unlock full unit identification (manufacturer, model, serial, age decoding, electrical specs, refrigerant charge), guided diagnostic troubleshooting steps, OEM replacement parts with part numbers, and a customer-ready quote draft in under 60 seconds.

### The Problem
Frontline field technicians burn 20 to 40 minutes per service call scraping grime off rusted data plates, deciphering cryptic manufacturer serial numbering schemas, searching for out-of-print PDF installation manuals in cell-dead basements, and making frantic calls to senior service managers to look up capacitor ratings or diagnostic blink codes. This friction drives up unbillable truck roll hours, delays customer estimates, leads to wrong parts ordered, and costs contractor companies thousands in lost margin and billing leakage every month.

### The Solution
HVAC PlateReader Pro delivers a multimodal, field-tested diagnostic copilot powered by the Sensifai AI Engine combined with deterministic engineering logic and cross-brand serial decoders. Technicians upload or snap a nameplate photo, control board status, or voice symptom memo. In seconds, the system extracts the exact model and electrical specs, decodes the unit's true manufacture age across top brands (Carrier, Trane, Lennox, York, Goodman, Rheem, Daikin, Mitsubishi), provides a photo-verified fault isolation checklist, pulls recommended replacement parts, and produces a professional parts and labor repair quote.

### Key Capabilities
- High-accuracy multimodal OCR for worn, weathered, curved, or rotated equipment data plates
- Multi-brand serial number age decoding (Carrier, Trane, Lennox, York, Goodman, Rheem/Ruud, Daikin, Mitsubishi)
- Full electrical specification extraction: MCA (Min Circuit Ampacity), MOCP (Max Overcurrent Protection), Voltage, Phase, RLA, LRA
- Refrigerant identification and factory charge specs (R-410A, R-22, R-32, R-454B)
- Error code interpretation from LED flash sequences, 7-segment digital readouts, and board status lights
- Photo-guided troubleshooting checklists with multimeter test points and safety interlocks
- One-tap customer quote builder: OEM replacement parts, universal equivalents, labor hours, and margin markup
- Exportable PDF inspection certificates, technician dispatch work orders, and field service CRM webhooks
- Transparent Sensifai prepaid wallet metering at €0.05 per equipment diagnosis

### How It Works
Sign in with your Sensifai account, upload or capture equipment photos (nameplate, error code display, control board, or wiring diagram), review extracted equipment specifications and age verification, follow step-by-step diagnostic fault procedures, review replacement parts, and export a signed customer repair quote or maintenance certificate metered at €0.05 per case from your Sensifai prepaid wallet.
