Job description

Senior Service Technician | Airmakers Air Conditioning Services Pty Ltd

We’re not lookin’ for another install cowboy or a call-centre-trained “tech” who needs three goes to find a fault.

We’re chasing a proper senior service technician.

Someone who walks onto site, scopes the setup, hears the rattle, sees the leak — and already knows the next three steps.

You still like being on the tools.
You take pride in your finish.
And you don’t lose your cool when the job goes sideways.

You’re sharp with diagnostics.
Tight with your vehicle.
Steady when juniors need a hand.

You don’t need hand-holding — you need room to lead.
And a company that’s not running on chaos and crossed fingers.

You’re looking for something better.
But it’s got to be worth it.

You want structure. respect. trust.
You want work you’re proud of.
And a team that backs each other up without the drama.

You want to step up — not off the tools, just into more responsibility.

And that’s exactly what this is.

About Us:

We’re Airmakers Core Services Pty Ltd — a Western Sydney-based, proudly independent company known for quality work across commercial, light industrial services and maintenance.

We run a tight crew with strong systems and steady workflow. no mess, no dead days.

Our focus is service — not smash-and-grab installs.

We don’t do egos.
We don’t do “near enough”.
And we don’t do three-hour “team-building” lunches that waste your time.

We do clean finishes, clear comms, sharp thinking, and backing our techs to lead from the front.

And right now, we’re looking for a senior tech who’s ready to raise the bar with us.

Reasons to join Airmakers:

• no weekend work – Saturdays and Sundays are yours
• tight-knit crew – no egos, no slackers, no cliques
• clear job expectations – no shifting goalposts, no confusion
• training + upskilling – we’ll back you to keep growing
• treated like a professional – your work and time are respected
• supportive leadership – you’re not left hanging in the field
• career progression – mentor, lead, step up — without stepping off the tools
• we’re growing, not slowing – the pipeline’s strong and steady
• company vehicle – fully stocked, fuel card for you to use on the job.

We work all over Sydney & Western Sydney whilst also completing various projects all over NSW.

About the role:

This is a hands-on leadership role.

You’ll still be on the tools — but you’ll also be the standard-setter in the field.

• take the lead on service calls, maintenance and breakdowns — from ducted systems to vrv
• own the diagnosis, guide the apprentice, and get the job done properly
• coach junior techs — don’t just bark orders, actually teach
• keep Servicem8 sharp — real-time notes, photos, no memory-based guessing
• stay in touch with the service manager — flag delays, client feedback, follow-ups
• help spot upsells, quote support, and customer upgrades where needed
• represent the brand in the field — clean, respectful, reliable

You’re trusted to manage your day and your jobs — the right way.

What you'll actually be doing:

• diagnosing and repairing split, ducted, vrv/vrf and multi-head systems
• owning jobs from start to finish — clean, correct, client-ready
• leading by example on-site — safety, standards, attitude
• mentoring apprentices and junior techs — show your thinking, build their skills
• documenting properly in servicem8 — job notes, materials, before/after photos
• managing your van stock — restock ahead of time, not after the fact
• helping identify quote and upgrade opportunities
• maintaining clean, compliant sites — zero shortcuts, zero mess
• being proactive with communication — no ghosting the office or clients
• showing up on time, prepared, and with the right mindset

What you'll need:

• certificate iii in air con & refrigeration
• arctick refrigerant handling licence
• white card + valid driver’s licence
• 5+ years hands‑on in service and maintenance
• proven experience mentoring or leading others on‑site
• strong comms + client relationship skills
• confidence using Servicem8 or similar job software
• pride in your work, and zero tolerance for dodgy jobs

what good looks like:

• 95%+ of jobs completed on time and to spec
• 100% of jobs updated in Servicem8 with clean notes + photos
• <5% repeat callouts within 30 days
• van kept clean + stocked weekly — photos submitted
• quotes supported within 48 hours of diagnosis
• upsell wins + opportunities flagged proactively
• zero safety breaches, fully compliant sites
