HVAC Field Operations & Technical Support Center

Launch HvAI. The native runtime queries system display metrics and applies dynamic window inset padding for field visibility across 360dp to 1080dp viewports.

Authenticate via Google Identity Services or enter your technician corporate email to receive a high-entropy 6-digit verification nonce.

Input the authoritative 8-character enterprise company token. The client verifies tenant membership against the Supabase tenant directory.

Authorize runtime permissions: BLUETOOTH_SCAN, BLUETOOTH_CONNECT, and ACCESS_FINE_LOCATION (essential for BLE beacon distance calculation and WGS-84 job site locks).

Open "Sites" in the bottom drawer. The integrated geolocation subsystem computes Euclidean proximity to existing client facilities and highlights the nearest site.

Capture a wide contextual perspective (3 to 5 meters standoff) illustrating rooftop position, adjacent RTUs, line-set routing, and proximity to building parapets.

Document condenser coil fin integrity, microchannel oxidation, electrical contactor pitting, dual-run capacitor terminals, and compressor vibration grommets.

Tap the microphone icon to transcribe diagnostic audio findings directly into the photo metadata container without removing your insulated work gloves.

Position the camera viewfinder perpendicular to the aluminum nameplate at a 20–30 cm focal distance, minimizing specular rooftop sun reflection.

The neural pipeline parses text vectors into discrete tokens: Model String, Serial String, Refrigerant Classification (e.g., R-410A, R-22, R-454B), and Factory Charge (lbs/oz).

If physical corrosion causes OCR uncertainty, tap any field to manually adjust characters. HvAI compares candidate models against the internal AHRI directory.

Select the equipment morphology (Packaged Rooftop Unit, Split Condensing Unit, Heat Pump, Mini-Split) and assign the sequential facility tag (e.g., "RTU-01").

Depress the power switch on each JL3PR pressure probe and JL3PC pipe clamp until the status LED flashes blue, indicating active BLE 2.4 GHz advertising mode.

Navigate to "PROBES" in HvAI. The BLE engine scans GATT advertisement packets and maps unique MAC addresses to Low-Side (Suction) and High-Side (Liquid) circuit slots.

Mount the blue JL3PR to the low-side suction service valve port; mount the red JL3PR to the high-side liquid service valve. Secure the JL3PC clamps on cleaned bare copper.

Inspect live Evaporator Saturation Temperature ($T_{sat}$), Condensing Temperature ($T_{cond}$), Superheat ($SH$), Subcooling ($SC$), and Airflow Delta-T ($Delta T$).

Power on your Testo Smart Probes (long press until amber flashes green) or UEi HUB modules. Verify battery voltage is above 2.4V to prevent RF packet dropouts.

Tap "Scan Probes". The engine scans broadcast advertisements across BLE channels 37, 38, and 39, indexing device UUIDs and RSSI signal strengths in decibels.

If clamps were mounted in reverse, tap the "SWAP SIDES" button to digitally flip Suction and Liquid roles without physically releasing refrigerant from valve cores.

Ensure pressure probes are zeroed to ambient atmospheric pressure ($14.696\text{ psia}$ at sea level) prior to valve depression. Select correct glide profile for zeotropic blends.

Review aggregated findings across all inspected units (e.g., RTU-1: Subcooling restored to 11.2°F, dual capacitor replaced 45/5 µF, blower belt tensioned).

Toggle photos to include in the client report. Select "Keep Local" if sensitive customer facilities restrict cloud AI processing, ensuring all data remains on-device.

Rotate device to horizontal landscape mode. The full-bleed capacitive canvas captures stylus or finger vector coordinates, velocity, and stroke pressure.

Tap "Submit & Sign". The system compiles a certified PDF/A document, transmits a real-time event to the office dispatch portal, and queues a client copy via email.

Navigate to `https://login.hvai.tech` in Chromium, Safari, or Firefox. Log in with your corporate enterprise credentials or administrator invitation.

Open `/supervisor`. The interface displays active field technicians, current rooftop equipment under diagnostic evaluation, and streaming live Superheat/Subcooling gauges.

Open `/dispatch` to audit inbound signed field packets, verify customer timestamps, inspect high-resolution equipment photos, and download certified PDFs.

Query past work orders by Model Number, Serial Number, or Property Address to view chronological service history, past refrigerant charges, and compressor replacements.

In the Office Navigation bar, inspect technician status badges (e.g., Shane #101: Diagnostics Active on RTU-2; Tony #104: In Transit).

Click the green "WHATSAPP CALL" button in the navigation bar to immediately ring the technician via end-to-end encrypted VoIP audio or video.

Observe live subcooling and superheat trends simultaneously with the technician to diagnose thermal expansion valve (TXV) bulb detachment or restricted filter-driers.

If severe corrosion obscures the physical nameplate, the office supervisor can verify unit specs in the manufacturer portal and inject confirmed values into the tech’s active session.

Swipe open the navigation drawer or tap the profile avatar in the upper right corner to expose the display configuration panel.

Toggle "Sun Mode". The theme immediately inverts background surfaces from deep slate (#090D16) to pure reflective white (#FFFFFF), updating Android system bar icons for high visibility.

When moving from rooftop condenser units into dark residential attics or commercial mechanical rooms, toggle back to Dark Mode to conserve OLED battery power.
