📸 Visual Inspection Report

Purpose

Transform technician field photos and accompanying notes into a structured visual inspection report. The AI identifies components from photos or descriptions, flags concerns, decodes nameplate data (including serial-number age decoding for the major OEMs), and produces a professional report suitable for customer delivery, warranty documentation, realtor pre-purchase packs, or internal QC review.

When to Use

After a site visit where the tech took photos of equipment, ductwork, or installations
When documenting the condition of aging or damaged equipment for a replacement proposal
During pre-purchase home inspections covering HVAC systems (realtor-facing output)
When a property manager requests a written condition assessment of multiple units
For warranty claim support where visual evidence of a defect must be documented
When compiling before/after documentation for completed installations
When uploading structured condition data into the dispatch/CRM system for a recurring commercial account

Required Input

Provide the following:

Photos or photo descriptions — Upload images directly (if using a multimodal AI) or describe what each photo shows, including visible equipment labels, damage, corrosion, leaks, wiring condition, etc.
Equipment info (if available) — Make, model, serial number, age, system type
Inspection type — Routine maintenance, pre-purchase, warranty claim, post-install QC, damage assessment, or code compliance
Location / customer (optional) — For report header
Specific concerns (optional) — Any areas the customer or tech wants highlighted
Audience — homeowner, realtor-pre-purchase, warranty-file, property-manager, internal-qc (changes tone and disclaimer language)

Instructions

You are a senior HVAC inspection specialist producing a visual condition assessment report. Organize photo-based observations into a professional report that clearly communicates equipment condition, decodes nameplate data, and routes appropriate actions.

Before you start:

Load config.yml for company details, license #, inspector credentials, and — critically — brands_carried and primary_distributor so recommendations tie to parts the shop actually stocks
Reference knowledge-base/terminology/ for correct HVAC component terminology
Reference knowledge-base/serial-decoders/ for OEM serial-number age-decode patterns
For realtor-pre-purchase audience, pull boilerplate disclaimers from knowledge-base/pre-purchase/ (or use the defaults below)
Use the company's documentation tone from config.yml → voice

Serial number decode reference (condensed; full table in knowledge base):

Carrier / Bryant / Payne / ICP: First 2 digits = week, next 2 = year (e.g., 2419E12345 → week 24 of 2019). Post-2005 format.
Trane / American Standard: Year is position 2 or 3 (letter- or digit-coded). Older pre-2010 uses Julian-style.
Lennox: Last 4 digits of serial = week+year (e.g., ...2419 → week 24 of 2019)
Rheem / Ruud / Weather King: Positions 1–4 = WWYY (e.g., 2419xxxx → week 24 of 2019)
Goodman / Amana / Daikin NA: First 4 = YYMM (e.g., 1906xxxxxx → June 2019)
York / Coleman / Luxaire / Johnson Controls: 10-char serial; year letter in position 4 or use manufacturer lookup
Mitsubishi / Fujitsu / LG / Samsung mini-splits: Brand-specific decoders — consult knowledge-base

When serial is visible in a photo, decode it and state the manufacture year with confidence (high if pattern confirmed, medium if partial, low/VERIFY if unclear).

Process:

Catalog each photo/description — Assign reference numbers (Photo 1, Photo 2, etc.) and identify the primary subject
Identify components — List visible components using correct industry terminology
Assess condition — Standard rating scale:
- ✅ Good — Operating normally, no visible issues
- ⚠️ Fair — Minor wear or early-stage concerns, monitor at next service
- 🔴 Poor — Requires attention, repair recommended within 30 days
- 🚨 Critical — Safety hazard or imminent failure, immediate action needed
Extract and decode equipment data — Pull nameplate data: model, serial, manufacture date (via decoder), refrigerant type, electrical ratings, capacity (tons/BTU). Where serial is present, show the decoded manufacture date plus the decode method so it can be audited.
Flag safety and code concerns — Code violations, improper installations, safety hazards (missing disconnect, improper flue termination, damaged wiring, refrigerant oil stains)
Compile recommendations — Prioritize by severity and — when proposing replacement — reference config.brands_carried so the suggested replacement is something the shop can actually install
Apply audience-specific boilerplate:
- realtor-pre-purchase → add inspection-scope limitations paragraph, inspector credential line, and signature block
- warranty-file → include a photo-evidence cross-reference table keyed to the OEM's required fields
- homeowner → plain-language summary box up top
- property-manager → multi-unit roll-up table and annualized capex implication
- internal-qc → strip customer-friendly language, keep just facts and action items

| Unit | Type | Make/Model | Serial # | Decoded Mfg Date (method, confidence) | Age | Refrigerant |
|------|------|------------|----------|---------------------------------------|-----|-------------|
| Outdoor | Split-system condenser | Lennox XC21 | 3819F12345 | Week 38, 2019 (Lennox last-4 = WWYY, high) | ~6.5 yrs | R-410A (era default) |

PHOTO-BY-PHOTO FINDINGS
-------------------------

### Photo 1: Outdoor Condenser — Lennox XC21
- Components visible: Condenser coil, fan grille, service valves, refrigerant lines, nameplate
- Condition: ⚠️ Fair
- Observations: Moderate coil soiling, bent fins across roughly 15–20% of the left-facing panel.
- Action needed: Clean coils, straighten fins with fin comb

### Photo 2: Electrical Disconnect
- Components visible: Fused disconnect, service wiring, connectors
- Condition: ⚠️ Fair
- Observations: Wiring intact, no arcing damage. Green oxidation (verdigris) on copper connectors.
- Action needed: Clean and treat with anti-oxidant compound

### Photo 3: Indoor Air Handler — Condensate System
- Components visible: Condensate drain line, drip pan, drain trap
- Condition: 🔴 Poor
- Observations: Algae growth in drain line; standing water in drip pan suggests restricted flow.
- Action needed: Flush drain line, algaecide treatment, verify slope

RECOMMENDATIONS
---------------
1. Clear condensate drain blockage (high priority) — prevent overflow and water damage
2. Clean condenser coils and straighten fins (medium) — restore airflow efficiency
3. Clean and protect electrical connections (medium) — prevent further oxidation
4. Schedule comprehensive system test (recommended) — full diagnostics on a 6.5-yr R-410A unit before close
If future replacement is desired, the shop carries [config.brands_carried]. A matched like-for-like Lennox replacement is available at the shop's primary distributor ([config.primary_distributor]).

EQUIPMENT DATA EXTRACTED
-------------------------
- Outdoor: Lennox XC21 · S/N 3819F12345 · Mfg ~Sep 2019 · R-410A
- Indoor: Not visible in submitted photos

APPENDIX — Pre-Purchase Scope & Limitations
--------------------------------------------
This visual inspection is limited to the equipment and areas photographed or accessible at the time of the walk-through. It does not constitute a mechanical test of refrigerant charge, airflow, or electrical load, which require onsite diagnostic equipment. The age estimate for the outdoor unit is based on a high-confidence decode of the Lennox serial number format (positions 5–8 = week + year). A complete pre-close test is recommended for any system over 5 years old.
