HomeServicesCommercial Air Conditioning Repairs
When the air conditioning fails in an office, shop or cafe, the heat hits staff, customers and stock together. We handle commercial air conditioning repairs in Rockhampton for offices, shops and cafes, from a single dead cassette unit to a whole floor that has stopped cooling. Rockhampton's climate means these systems run for most of the year, so a fault rarely stays small for long.
We work on the systems found in local commercial buildings: wall splits, ceiling cassettes, under-ceiling units, rooftop package units, ducted systems and VRF/VRV multi-zone setups. We deal with site managers and property managers on access, reporting and sign-off, and we plan the work around your trading as far as the job allows.
Call 07 3543 8972 or send the quote form to get a commercial repair started. Tell us the site, the type of system and what it is doing, and we will price the job. Photos of the unit and any error code on the display help us work out what to bring.
Rockhampton offices, shops and food businesses run a mix of small and large systems, and each fails in its own way. These are the common ones.
Many small offices and retail tenancies run several wall-mounted splits rather than one central plant. That means a fault can take out one room while the rest keeps working. We trace the cause in the indoor unit, outdoor unit or the wiring between them, then repair or replace the failed part, such as a fan motor, capacitor or control board. Because the other rooms usually keep running, we can often work in one tenancy area without shutting down the whole site.
A four-way cassette air conditioner sits in a suspended ceiling in many offices, while under-ceiling units are common in shops and cafes. Water leaking from a cassette usually points to a blocked drain line or a failed condensate pump, and it can stain ceiling tiles fast. We clear drains, test pumps and check the fan and coil before closing the ceiling back up. In cafes and shops we also check how the unit sits over customer areas, so a drip never lands on a counter or a table.
Package units are self-contained systems, usually on the roof, with ducting running down into the space below. They work hard and sit in full sun, so fans, compressors and coils take a beating. We diagnose the unit from the roof and the controls, and we plan access before any parts are ordered. Common faults include failed fan motors, tripped safeties, blocked coils and worn contactors, and each needs a different fix.
VRF air conditioning (also called VRV) serves many indoor units from shared outdoor plant, so one fault can show up across several rooms. We read the error code on the affected indoor units and the outdoor unit to pin down whether the problem is a single zone, a sensor, the refrigerant circuit or the communication between units. Working this way avoids replacing parts that were never the problem, which matters on larger systems where a single indoor board or sensor can mimic a bigger failure.
Planned commercial air conditioning service keeps units running through the long cooling season. A visit covers filters, coil cleaning, drains, fans, controls and a check of operating pressures. Catching a dirty coil or a weak capacitor early costs far less than a breakdown in the middle of a hot trading week. We report back on the condition of each unit so you can plan for any repairs coming up, and we can set the visits to suit your trading calendar.
Commercial jobs involve more people and more access issues than a house. This is how we run them, from first contact to the report you keep.
We agree who to meet on site and how to reach the roof, plant room or ceiling space. We also plan the work around customers and staff, so noisy or disruptive tasks are scheduled with your input. If tenants, landlords or a building manager are involved, we confirm who approves access before we start.
We check the controller and any building management system alarms first, then move through the indoor units and the outdoor plant. Error codes, pressures, electrical readings and airflow tell us where the fault actually sits, so we fix the cause and not just the symptom.
You receive a written quote for the repair, sent to the owner or property manager. Work goes ahead once it is approved, and any extra faults found along the way are raised with you first, with a clear note of what each one involves.
We complete the repair, test the system and report back in writing. The report covers what we found, what we did and what we recommend next, so owners and managers have a record of the work and can plan ahead for any follow-up.

Rockhampton needs cooling for most of the year, not just summer. The Bureau of Meteorology records about 140 days a year at or above 30°C at Rockhampton Aero, and about 20 days at or above 35°C.
Winter barely interrupts it. July still averages a 23.3°C top, and a near-freezing morning comes around roughly once a year, so commercial plant cools far more than it heats.
That runs commercial plant for long hours. Shopfronts with large glass areas, commercial kitchens and small server cupboards add heat load on top of the weather, and a package unit on a sun-baked roof has to keep up with all of it. Units that run this hard need their coils, filters and drains kept clean, or a minor fault turns into a full breakdown.
Commercial air conditioning work sits under Queensland licensing rules, and they apply to every job on your premises.
The Queensland Building and Construction Commission (QBCC) defines mechanical services work as the construction, installation, replacement, repair, alteration, maintenance, testing or commissioning of heating and cooling systems, including air conditioning, in commercial and residential buildings. Commercial repairs fall inside that definition, so the licensing rules apply to them in full. QBCC offers three air-conditioning and refrigeration licence classes: unlimited design, limited design and occupational.
An ARCtick card covers the gas side only. On commercial plant in Queensland, the wiring takes an electrical worker licence or a restricted electrical work licence for refrigeration and air conditioning. The Electrical Safety Office adds that a restricted licence stops short of installation work, such as installing interconnect cables.
Every commercial repair ends with a written job report. It records the fault, the work completed and any recommendations, so owners, property managers and facilities staff can keep it with the building's maintenance records. If a unit is near the end of its life, the report says so plainly, which helps with budgeting for the next cooling season.
No two commercial faults cost the same, so we quote each job after we have seen the system. These are the main things that move the price, and we go through them with you when we quote.
A wall split, a cassette, a package unit and a VRF system differ in parts, labour and diagnosis time. Larger multi-zone plant takes longer to test.
Roof access, ceiling height, lifts and trading hours all affect how long a job takes and what equipment we need on site, particularly for package units.
Repairing one failed unit is a smaller job than working through several units or a whole zone that has stopped cooling.
Commercial parts such as a PCB, compressor or fan motor are not always on the shelf. Availability can affect how long the repair takes and what it involves.

Commercial buildings use several types of air conditioner, depending on size and layout. Small offices and shops often run wall splits, while cassettes and under-ceiling units suit suspended ceilings and cafes. Larger sites use rooftop package units, ducted systems, or VRF/VRV multi-zone plant.
Commercial air conditioners should be serviced at least once a year, ideally before summer. Sites with long trading hours, commercial kitchens or dusty conditions often need visits more often, because filters and coils clog faster and units work harder.
A commercial system needs replacing when repairs keep recurring or the cost of fixing it approaches the cost of a new unit. Other signs include parts that can no longer be sourced and older units that run on R22 refrigerant, which has been phased out. We can talk through repair versus replacement when we quote.
Yes, many commercial air conditioning systems can be controlled through a building management system (BMS), particularly VRF and package units. The BMS lets a manager set schedules, adjust temperatures and see alarms from one screen. When a unit faults, those alarms help us find the problem faster.
