# HVAC Mechanic — Trade Reference — L0: Production reference for the Built Different HVAC Mechanic character. Markdown is the SOURCE OF TRUTH (agents read this to write render prompts); the HTML view is generated from it. Each tool has a prompt-ready visual description + how-held + a real reference image + source. NS/CSA-specific PPE. See [[Production-Guide]] for the campaign-wide rules.

> **How this works:** edit this file → run `python3 build.py HVAC-Mechanic.md` → the HTML rebuilds in sync. Comments (Juan + Larry) live in this file (bottom) and flow into the HTML.

## Subject
*Everything about WHO we're rendering, in one place. The client spec is LOCKED (HCCNS chose each demographic deliberately) — the research below adds believable texture WITHIN it, never overrides it. The single highest-leverage realism cue is **hands + forearms** (NB models default to soft/manicured — push the render prompt hard here or you get a model in a costume).*

### Client spec (LOCKED)
- **Representation:** Pacific Islander woman, mid-20s, ball cap with hair in a ponytail.
- **Trade:** HVAC (Refrigeration & Air Conditioning Mechanic). NS.
- **Pose intent:** proud, in her element, head up, quiet authority (per [[Production-Guide]] §2).
- **Recommended loadout:** manifold gauge set in hand (hero) + ball cap + CSA safety glasses + a clamp meter OR IR thermometer as a secondary belt prop. Skip the pipe wrench; don't show both meters.

### Face & features (prompt-ready)
- Warm medium-brown skin, golden undertones, lightly sun-touched on cheekbones/nose/forehead from rooftop work. **Real, not retouched:** visible pores, faint unevenness, light T-zone shine (not matte makeup), maybe a small freckle or faint old blemish.
- Broad softly-rounded face, full cheeks; wide-set dark brown eyes with gentle epicanthic softness; broader nose, rounded tip; full naturally-pigmented lips; grounded slightly-square jaw; naturally thick dark brows. **Deliberately NOT perfectly symmetrical** — an authentic human face, not a render.
- Hair: dark brown-black, thick, practical low-mid ponytail fed through the back of the cap; a few flyaways, crown flattened by the cap — not a styled blowout.
- Expression (read "proud, in her element," never a stock grin): closed-mouth confident half-smile chin-up + direct eye contact; OR neutral-focused just-glanced-up; OR slight genuine smile with real eye-crinkle.

### Build & physiology of the craft
- A few years in, **functionally strong, not gym-sculpted.** Solid through shoulders/back from hauling 50–100+ lb compressors and toolbags. Real mass — **not slight, not a slim catalog body**; a little softness is more believable than a shredded core.
- **Forearms noticeably developed** (lean muscle, visible tendon/vein) from wrenching, flaring copper, hand-bending tubing — this is why the henley sleeves push to mid-forearm. Most important "real tradesperson" tell after the hands.

### Hands (CRITICAL — working hands, not manicured)
- Short practical nails, clean but UNPOLISHED, maybe a faint grime shadow at a cuticle. Slightly rough/dry knuckles.
- A small healing nick or thin scab on a knuckle; maybe one faint older scar. Mild callusing at palm base + finger pads.
- Hands that clearly DO something — clean but not soft, no rings/jewelry (catches in equipment).

### Character / expression
- Grounded, capable, direct — solved the problem before you finished describing it. **Quietly competent, not performing confidence.** The eyes do the work: steady, unbothered, faintly amused. No arrogance, no eager-to-please grin.
- Posture: squared shoulders, weight settled (or one hip slightly loaded), head up/chin level-to-slightly-raised, tall-but-relaxed. Arms loosely crossed, a hand on a unit/tool, or thumbs hooked in the belt — earned stillness, not a posed hero stance.

### Wardrobe under the PPE (campaign-locked layer)
- **Long-sleeve henley**, sleeves pushed to **mid-forearm**; muted practical color (heather grey, faded navy, charcoal, forest green); soft worn cotton, slightly faded, an honest stain or two — not box-fresh.
- **Work pants:** durable utility/duck-canvas (Carhartt-style), tan/brown/khaki/grey, reinforced knees, scuffs.
- **Ball cap:** plain structured-but-broken-in, muted solid, brim slightly curved, ponytail through the back gap, light sweat-shadow at the band. Generic/unbranded — no real recognizable brand.

### Authenticity flags — THE PERSON (anti-AI-slop)
1. **Manicured/polished/long nails** — instant fake; real HVAC hands are short, slightly rough, maybe nicked.
2. **Full glam makeup** (contour, lashes, gloss, sculpted brows) — she'd have bare/near-bare skin with natural shine.
3. **Pristine box-fresh clothing / flat-bill sticker cap** — real gear is faded, lightly stained, broken-in.
4. **Too-perfect symmetrical "render" face** (no pores, identical brows) — needs asymmetry, pores, a small mark.
5. **Body too slight/delicate** to move 80-lb equipment — needs real shoulders, back, forearms.
6. **Vacant catalog grin** aimed nowhere — replace with calm direct competence.

### NS / representation note
- Pacific Islander women in the trades are real and underrepresented — show her as **competent and ordinary, not exotic.** Render her as an INDIVIDUAL, not a "type": NO tropical/island styling, leis, florals, or cultural costuming — she's a working Nova Scotian HVAC mechanic, full stop. Heritage shows only in natural features, never props.
- Maritime-honest, not beachy: neutral indoor-mechanical or overcast-outdoor light, NOT sun-drenched "island" lighting. The strongest, most respectful representation is **unremarkable competence** — she's in frame because she's good at the job.

## Tools
*The hero/paradigm prop is marked ⭐. Props are HELD accessories, not the focus.*

### 1. Manifold Gauge Set ⭐ hero
![manifold-gauge-set](assets/hvac-mechanic/manifold-gauge-set.jpg)
- **Visual (prompt-ready):** two round analog pressure dials side-by-side on a metal manifold body — left dial ringed BLUE (low/suction), right dial ringed RED (high) — a row of valve knobs along the bottom, and three rubber charging hoses (blue, red, yellow) coiling off the base.
- **Held:** in one hand by the manifold body at chest height, colored hoses draped over the forearm. Reads instantly as "HVAC."
- **Material:** chrome/brushed-aluminum body, red/blue plastic dial bezels, black rubber hoses with brass fittings.
- **NS note:** modern NS techs often carry a DIGITAL manifold (LCD) for R-410A / A2L refrigerants; analog or digital both read authentic.
- **Also called:** gauge manifold, charging manifold, test & charging manifold, AC gauge set (brands: Yellow Jacket, CPS, Mastercool, Robinair).
- **Source:** [Yellow Jacket 41345 manifold gauge set — product shot (jbtools.com)](https://www.jbtools.com/yellow-jacket-41345-r-134a-series-41-manifold-gauge-with-couplers/)

### 2. Clamp Meter
![clamp-meter](assets/hvac-mechanic/clamp-meter.jpg)
- **Visual (prompt-ready):** a handheld meter with a hinged jaw/claw at the top (clamps around a wire), a digital LCD below, a rotary function dial, two test-lead jacks at the bottom. Like a multimeter with pincers on top.
- **Held:** one hand on the body, thumb on the jaw trigger.
- **Material:** grey/red or yellow/black plastic housing; moulded jaw over a metal core.
- **NS note:** measures compressor/condenser fan amp draw. The more HVAC-distinctive of the two meters — prefer over the plain multimeter.
- **Source:** [Amprobe clamp meter (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Amprobe_Clamp_Meter.JPG)

### 3. Infrared Thermometer
![ir-thermometer](assets/hvac-mechanic/ir-thermometer.jpg)
- **Visual (prompt-ready):** pistol/gun-shaped handheld with a stubby pointed barrel (IR lens) at the front, a digital LCD on the back of the grip, a trigger; a laser dot aims it at a vent or refrigerant line.
- **Held:** pistol-grip, pointed outward like aiming — very photogenic for a portrait.
- **Material:** yellow-and-black or red-and-black rugged plastic.
- **NS note:** techs also use a clamp/pipe thermometer for supply/return temp split, but the IR gun is the most recognizable "measuring temperature" read.
- **Source:** [Infrared thermometer (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:An_infrared_thermometer.JPG)

### 4. Vacuum Pump
![vacuum-pump](assets/hvac-mechanic/vacuum-pump.jpg)
- **Visual (prompt-ready):** a compact bench-top pump — horizontal cylindrical motor body bolted to an oil-reservoir base, carry handle on top, hose intake port on the front, oil sight-glass on the side.
- **Held:** carried by the top handle at the side like a small case; too heavy to hold up — sits at the leg or on the ground.
- **Material:** painted metal (grey/blue/yellow), cast-metal base, black handle. Often oil-stained in the field.
- **NS note:** yellow Robinair/JB-style is the field icon; NAVAC cordless pumps increasingly common in NS.
- **Source:** [Rotary-vane vacuum pump (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Edwards_E2M2_2-Stage_Rotary_Vane_Vacuum_Pump_(15957733526).jpg)

### 5. Tubing Cutter
![tubing-cutter](assets/hvac-mechanic/tubing-cutter.jpg)
- **Visual (prompt-ready):** a small C-shaped clamp tool — a sharp circular cutting wheel on one jaw, two roller bearings opposite, a knurled knob at the end; a fold-out triangular reamer often hinges off the body.
- **Held:** wrapped around a length of copper pipe, mid-rotation — or held up by the body.
- **Material:** die-cast metal (silver/blue/red), steel cutting wheel.
- **NS note:** core line-set tool for residential mini-split installs.
- **Source:** [Copper tubing cutter (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Tube_cutter_cutting_three_fourths_inch_copper_pipe.jpg)

### 6. Multimeter
![multimeter](assets/hvac-mechanic/multimeter.jpg)
- **Visual (prompt-ready):** a rectangular handheld meter, grey-and-yellow rubberized body, digital LCD at top, rotary dial in the center, two test leads (red + black) with pointed probe tips plugging into the bottom.
- **Held:** one hand, screen facing out; or clipped in a tool-pouch with leads dangling.
- **Material:** yellow-and-grey impact plastic (Fluke's signature look).
- **NS note:** Fluke dominant in Canadian HVAC. ⚠ Redundant with the clamp meter — pick ONE (prefer the clamp meter).
- **Source:** [Fluke 115 multimeter (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Fluke_115_multimeter.jpg)

### 7. Cordless Drill/Driver
![cordless-drill](assets/hvac-mechanic/cordless-drill.jpg)
- **Visual (prompt-ready):** pistol-grip power drill, keyless chuck at the front, torque collar behind it, trigger, slide-in battery pack forming the base of the grip.
- **Held:** pistol-grip, one hand, pointed up or resting on the shoulder — confident trades pose.
- **Material:** bright branded plastic — yellow/black (DeWalt), teal (Makita), red (Milwaukee).
- **NS note:** ⚠ generic across all trades — not HVAC-distinctive alone. Only use paired with a clearly-HVAC tool.
- **Source:** [Cordless drill (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Dewalt_DCD985L2_Combi_Drill.jpg)

### 8. Pipe Wrench
![pipe-wrench](assets/hvac-mechanic/pipe-wrench.jpg)
- **Visual (prompt-ready):** a heavy adjustable wrench, long straight handle, offset hook-shaped serrated jaw at the head, knurled adjusting nut. Aggressive toothed jaws.
- **Held:** one-handed by the handle, head up; or hung from a belt loop.
- **Material:** cast iron/steel, often a RED or bare grey-steel handle.
- **NS note:** ⚠ WEAK HVAC fit — it's a plumbing/gas-fitting tool. As a hero prop it mis-reads the trade. Demote to belt accessory or drop.
- **Source:** [Pipe wrench (Wikimedia Commons)](https://commons.wikimedia.org/wiki/File:Pipe_wrench.JPG)

### 9. Flaring Tool
![flaring-tool](assets/hvac-mechanic/flaring-tool.jpg)
- **Visual (prompt-ready):** a small two-part hand tool: a flat steel BAR drilled with graduated holes for tube sizes, plus a sliding YOKE with a T-bar screw handle that presses a cone into the tube end; wing-nuts clamp the copper tube.
- **Held:** compact — in the palm or both hands mid-flare; often just clipped in a pouch.
- **Material:** forged steel / satin-nickel-chrome — silver/steel look (often a colored grip).
- **NS note:** standard for 45° flare joints on soft copper line sets — core NS mini-split task.
- **Also called:** flare tool, 45° flaring tool, bar/yoke flaring tool, eccentric flaring tool, tube flaring tool (brands: Imperial, Yellow Jacket, Rothenberger; German: Bördelgerät).
- **Source:** [Yellow Jacket 60278 Deluxe flare tool — product shot (trutechtools.com)](https://trutechtools.com/yellow-jacket-60278-deluxe-flare-tool-1-8-3-4/)

### 10. Refrigerant Leak Detector
![leak-detector](assets/hvac-mechanic/leak-detector.jpg)
- **Visual (prompt-ready):** a handheld wand — a pen/pistol-shaped body the size of a TV remote with an LED sensitivity bar (green/yellow/red) and a couple of buttons, and a flexible gooseneck probe (12–16 in.) arcing up from the top; the tip flashes/beeps on a leak.
- **Held:** one hand by the body, probe pointed up/out — natural "scanning" pose.
- **Material:** green or black/grey rugged plastic body, flexible black gooseneck.
- **NS note:** Canada's A2L/HFO transition means A2L-rated detectors are now standard.
- **Also called:** electronic/freon leak detector, refrigerant sniffer, halogen leak detector, A2L leak detector (sensor types: heated-diode, IR, corona; brands: Extech, Fieldpiece, Testo, CPS).

## Poses
*3 crop-validated options grounded in real HVAC work. All obey the campaign-wide posing rules in [[Production-Guide]] §Posing (face centered, no moat, prop at chest height, hands below chin). Pick one per render; the master is framed head→thigh.*

### Pose 1 — "The Gauge Read" (hero, recommended)
- **Body:** square-on, shoulders level/slightly squared, both forearms raised in front of the torso at lower-chest height, elbows pinned to the ribs. Head up/level, direct calm gaze, closed-mouth set — reading a number she already understands.
- **Prop:** manifold gauge set in both hands at sternum height, the red/blue dials angled UP toward camera so both read; colored hoses drape straight DOWN the centerline (crop cleanly). Stays inside shoulder width.
- **Square crop:** clean — face dead-center, cap in safe-zone, gauge at the bottom edge, not crowding the chin.
- **Portrait crop:** strong — face top, frontal forearms + working hands mid-frame, hero gauge as the focal anchor, hoses trailing toward the thigh crop.
- **Why HVAC:** reading the manifold IS the defining refrigeration act (charging/reading pressures) — most trade-specific thing she can do.
- **Risk:** keep hoses a clean vertical drape (not tangled); elbows pinned or they clip the square; dials must face up or render as blank edges.

### Pose 2 — "Arms Crossed, Tool Tucked" (authority, safest crop)
- **Body:** squared, tall, shoulders back, forearms crossed over the lower chest but TIGHT/compact, elbows close. Head up, slight chin-toward-camera, eyes to lens, quietly proud, no grin.
- **Prop:** clamp meter in the top hand of the fold, nested against the opposite forearm at chest height, jaws pointing UP/toward camera so it's identifiable. Reads carried/at-rest. Nothing past the upper-arm line.
- **Square crop:** the safest of the three — crossed arms pull everything inward; square is almost pure face + cap + shoulders, centered.
- **Portrait crop:** crossed forearms showcase the functional build + hands; clamp meter = clear secondary trade signal.
- **Why HVAC:** clamp meter = electrical/amp-draw diagnostics on compressors + condenser fans — everyday service check.
- **Risk:** most "stock-photo" of the three — kill that with no-smile + direct gaze + slight chin-down so it reads competent, not cliché. Don't let the meter render too small.

### Pose 3 — "The Thermal Scan" (dynamic, highest crop risk)
- **Body:** torso turned a subtle 10–15° off-axis (right shoulder forward), face rotated BACK to frontal-centered. Dominant forearm raised across the chest, hand in a pistol grip on the IR thermometer; off-hand at the tool belt. Caught mid-scan, settled focus.
- **Prop:** IR thermometer pistol-grip, barrel pointing UP-AND-INWARD across the chest (toward the opposite shoulder) — NOT at camera, NOT sideways. Chest height, inside the torso column.
- **Square crop:** clean ONLY if the head counter-rotates to centered; gripping hand stays below chin; barrel must not intrude up into the face zone.
- **Portrait crop:** the most energy of the three — angled torso + raised tool, build reads, belt tools fill the lower frame.
- **Why HVAC:** IR scan = checking supply/return temps + heat-signature faults — unmistakable HVAC read.
- **Risk:** highest. Barrel inward/up or it foreshortens to a blob / clips the square; raised hand can drift to the face — keep at chest; off-axis torso must not drag the face off-center.

## PPE — Nova Scotia / CSA (HVAC, mixed indoor + rooftop)
- **Safety glasses — YES, near-universal.** CSA Z94.3 rated (Canadian equiv. of US ANSI Z87). Clear lens. **The one PPE item that belongs in almost any HVAC portrait.**
- **Safety boots — YES, always.** CSA Z195 grade-1, green-triangle patch (the visible Canadian tell), steel/composite toe.
- **Gloves — situational.** Mechanics'/cut-resistant for sheet-metal + copper; often OFF for fine gauge/electrical work. A pair tucked in a back pocket reads authentic.
- **Hi-vis vest — NO (mostly).** Not worn for indoor residential/mechanical-room service. Only near moving equipment/roadways (CSA Z96). No vest is correct for this portrait.
- **Hard hat — NO (mostly).** Not worn for routine indoor residential service. A ball cap is normal; a hard hat would look staged. (Matches the brief.)
- **Fall protection (rooftop) — situational, not a portrait item.**

**Verdict on the brief's "ball cap, no hard hat, no vest":** realistic and correct for a residential HVAC service tech in NS. The must-add for authenticity is **CSA safety glasses** (+ CSA-toe boots if feet are in frame).

## Authenticity flags — tools & portrait (what a real HVAC tech clocks as fake)
1. **Manifold hoses connected to nothing, coiled wrong, or red/blue swapped** (blue = low, red = high, yellow = charging). Instantly noticed.
2. **No safety glasses while holding a live electrical/cutting tool** — bare eyes = stock-photo model, not a tradesperson.
3. **A plain pipe wrench as the hero prop** — signals plumber/gas-fitter, not refrigeration. HVAC's identity tool is the gauge manifold.
4. **Pristine, spotless tools + brand-new gloves/boots** — real field tools are scuffed and oil-stained (vacuum pump especially). Too-clean = AI-slop tell.

## Brief check
- **8/10 tools are HVAC-core** (manifold, multimeter, vacuum pump, leak detector, flaring tool, tubing cutter, clamp meter, IR thermometer).
- **Pipe wrench (#8):** weakest fit — plumbing/gas tool; demote or drop.
- **Multimeter + clamp meter:** redundant (both electrical meters) — show one, prefer the clamp meter.
- **Most iconic for the portrait:** manifold gauge set (hero) + one of clamp meter / IR thermometer.
