“We had a fantastic experience working with Mark and the team at Chill Merchants.
They installed a large air con system in our workshop and office where several high temp machines run all day. These ducted units are big and heavy, and I wanted experienced tradesmen doing the job, and that's what we got.”

“Chill Merchants were engaged by Bryant Building Contractors to deliver the mechanical services package at Bryant’s recently completed, Energy Quuensland Esitrain Redevelopment project and performed strongly from pre-tender until completion.
Their team completed all contracted works competently, efficiently, and in full accordance with project drawings and specifications. Communication was clear, site coordination was smooth, and their commitment to meeting program deadlines was evident throughout the build. Chill Merchant’s professionalism and reliability contributed to a seamless delivery, and Bryant will actively seek their services for future project.”

“Chill Merchants have completed a number of projects for us over the last 18 Months spanning minors works and duct work reconfiguration through to complete turn key commercial HVAC system installations.
Their communication, professionalism and trade knowledge is excellent. The transparency through the initial design and consultation process has helped to develop some great solutions to some very challenging problems. The installation team are extremely flexible, very thorough and produce high quality work. They turn up when they say they will and deal with onsite installation issues very quickly and with a minimum of fuss.
I would highly recommend Mark and the Chill Merchants Team to anyone.”

Common questions about working with Chill Merchants across Brisbane and South East Queensland.
On most commercial builds, mechanical services are the largest and most space-demanding trade in the ceiling and on the roof.
Ductwork, pipework, plant, risers, if mechanical isn’t coordinated early and installed on time, ceilings don’t close and other trades can’t finish. We sit directly on the critical path.
A good mechanical contractor helps the builder stayon programme. A poor one delays everyone.
We understand that. We plan early, issue shop drawings early, and get in when we saywe will. Builders don’t need noise, they need reliability.
Live construction is structured pressure.
We attend coordination meetings, work closely with site managers, and keep supervision active. Our supervisors are present. Our project managers are accountable. Works are photographed and documented.
Mechanical installs are sequenced properly so other trades can follow without friction. If we’re disorganised, everyone feels it, so we don’t operate that way.
From apprentices to tradesmen to supervisors and PMs, our team understands that how we perform on site reflects on the builder. We treat it seriously.
Compliance is handled from design through to commissioning, not at the end.
Ventilation rates, plant sizing, discharge locations, and NCC alignment are reviewed early. Where required, Form 15 and Form 12 certification is issued within our licensing scope, with consultant collaboration when needed.
But compliance is only half the job.
Quality assurance matters just as much. Regular site checks, workmanship standards, clean installs, straight duct runs, properly supported pipework, this is craft. Builders and owners notice it during walkthroughs.
We don’t just aim to pass inspection. We aim to deliver work we’re proud to put our name on.
Yes, and that’s common in commercial projects.
Retail and office fit-outs often run under tight deadlines. Mechanical systems may need staged commissioning, after-hours changeovers, or careful coordination to avoid disrupting other trades.
Programme pressure doesn’t justify cutting corners.
We plan around it. We communicate early. We bring enough supervision and labour to meet milestones without compromising quality or compliance.
Builders see mechanical as a risk trade. We operate in a way that reduces that risk.
Builders want partners, not headaches.
We hold appropriate QBCC mechanical licensing, electrical contractor licensing, and refrigeration licensing. We understand compliance pathways, documentation requirements, and commissioning standards.
But what separates us isn’t just licensing, it’s culture.
From apprentices to tradesmen, supervisors, projectmanagers, estimators, and engineers, we genuinely care about our craft. We seebuilders as partners. When a project succeeds, we succeed together.
Construction is high pressure. You need contractors who stay steady, accountable, and professional under that pressure.
That’s how we operate.
