Trusted by tradespeople across South East Queensland for a reliable, professional and rewarding place to work.
“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 Queensland 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 Merchants' professionalism and reliability contributed to a seamless delivery, and Bryant will actively seek their services for future projects.”

Common questions about working with Chill Merchants across Brisbane and South East Queensland.
A compliance audit is a structured review of an existing mechanical services installation to determine whether it meets current NCC requirements, relevant Australian Standards, and Queensland licensing obligations.
Audits typically assess ventilation rates, outside air volumes, exhaust discharge locations, plant installation, duct construction, controls, and certification records.
In many buildings, systems have been modified over time without proper documentation or engineering oversight. A compliance audit identifies gaps between current installation and regulatory requirements, allowing building owners to understand their exposure and rectify issues proactively.
Compliance is not assumed, it must be verified.
Over time, tenancies change, plant is replaced, layouts are altered, and contractors vary in capability. Not all modifications are engineered or installed under appropriate licensing.
Common issues include:
In Queensland, mechanical services work above regulated thresholds requires appropriate QBCC licensing. Works completed outside these requirements can create legal and compliance risk.
Rectification works bring systems back into alignment with NCC and Australian Standards requirements.
Rectification begins with engineering review.
We assess what was originally designed, what was installed, and how the system is currently performing. From there, we develop a structured scope of works that addresses deficiencies without unnecessary disruption.
Rectification may involve increasing outside air capacity, modifying ductwork, upgrading exhaust discharge, rebalancing airflow, reconfiguring controls, or providing missing compliance documentation.
The objective is to achieve compliance efficiently while protecting building operation.
Yes.
Where mechanical services work falls under Queensland regulatory requirements, Form 12 (inspection certificate) and Form 15 (design certificate) may be required.
Chill Merchants holds the appropriate mechanical licensing to issue required certification for works undertaken within our scope. Where historical certification is missing, we can assess what documentation may be required moving forward.
Proper certification is essential for audit readiness and regulatory protection.
Mechanical services work in Queensland is regulated under QBCC licensing requirements.
Electrical contractors holding limited air-conditioning qualifications (such as Certificate II level qualifications) are restricted in the value and scope of mechanical works they may legally undertake. Commercial mechanical projects above regulated value thresholds require appropriately licensed QBCC Mechanical contractors.
Chill Merchants operates under full mechanical, electrical, and refrigeration licensing and employs qualified trades across these disciplines.
Compliance is not just about installation quality, it is about operating within the law.
