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 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.”

Expert advice and compliance updates for commercial HVAC systems across South East Queensland.

Common questions about working with Chill Merchants across Brisbane and South East Queensland.
Commercial air-conditioning installation in Queensland is regulated under both QBCC legislation and electrical safety laws.
Mechanical services work exceeding the minor works threshold (generally $3,300 including labour and materials) must be undertaken by an appropriately licensed QBCC Mechanical contractor. Electrical works must be completed by a licensed Electrical Contractor in accordance with AS/NZS 3000.
A restricted electrical licence or CertII qualification does not authorise regulated mechanical services building work beyond minor thresholds. Commercial installations commonly involve refrigeration pipework, mechanical plumbing, ventilation systems, structural penetrations, and NCC compliance obligations.
Chill Merchants holds the required Mechanical, Electrical, and Refrigeration licences and delivers installations under qualified supervision, project management, and engineering oversight to ensure works are lawful, compliant, and professionally executed.
Compliance is addressedfrom the beginning of the project, not at handover.
Before installation, we review design intent, heat loads, ventilation requirements, and building usage to ensure alignment with the National Construction Code (NCC) and relevant Australian Standards, including AS 1668 and AS/NZS 3000 where applicable.
During installation, supervision focuses on correct pipework installation, drainage, ductwork integrity, electrical compliance, and structural penetrations. Installations are treated as regulated building systems, not standalone appliances.
Proper commissioning then confirms the system performs as designed.
Outside air and ventilation are critical components of compliant commercial installations and are often misunderstood.
Australian Standards prescribe minimum ventilation rates based on occupancy type. Offices, schools, kitchens, and amenities all have defined outside air and exhaust obligations.
An installation that ignores fresh air volumes, toilet exhaust balance, or make-up air requirements can create compliance exposure and performance issues.
We ensure ventilation systems are reviewed, installed, and commissioned correctly as part of the overall mechanical scope, not treated as secondary add-ons.
Yes. Proper installation involves validating system performance against the building’s actual demands.
We review heat loads, occupancy changes, and controllogic to determine whether improved zoning, VAV systems, VRF technology, or updated controls would provide better long-term outcomes.
Independent room temperature control is particularly important in Queensland buildings where solar load varies significantly across different areas of a structure.
The objective is to install systems that perform efficiently and reliably over their full design life — not simply replace equipment like-for-like.
Commercial installations require structured documentation.
Chill Merchants provides shop drawings (where required),as-built documentation, commissioning records, operation and maintenance manuals, and Form 12 and Form 15 certifications where applicable under Queensland legislation.
Electrical safety certification is completed in accordance with statutory requirements, and commissioning data confirms system performance.
This ensures installations are compliant, auditable, and properly handed over for long-term asset management.
