HVAC Mechanic

SAMPLE — format under review (build one, lock, then do the other 15)

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)

• Manicured/polished/long nails — instant fake; real HVAC hands are short, slightly rough, maybe nicked.
• Full glam makeup (contour, lashes, gloss, sculpted brows) — she'd have bare/near-bare skin with natural shine.
• Pristine box-fresh clothing / flat-bill sticker cap — real gear is faded, lightly stained, broken-in.
• Too-perfect symmetrical "render" face (no pores, identical brows) — needs asymmetry, pores, a small mark.
• Body too slight/delicate to move 80-lb equipment — needs real shoulders, back, forearms.
• 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.

Manifold Gauge Set ★ hero

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).

Clamp Meter

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.

Infrared Thermometer

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.

Vacuum Pump

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.

Tubing Cutter

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.

Multimeter

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).

Cordless Drill/Driver

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.

Pipe Wrench

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.

Flaring Tool

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).

Refrigerant Leak Detector

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.
