Introduction
Choosing the right commercial air conditioning system isn’t as simple as picking a brand and size. The wrong choice can lead to high energy bills, poor comfort, and premature equipment failure.
At Shelair, we’ve designed and installed commercial HVAC systems across Brisbane, the Gold Coast, and the Sunshine Coast for more than 30 years. Here’s what every business should consider before investing in a new system.
1. Understand Your Building and Usage Requirements
Every commercial space is different. Offices, retail stores, aged care facilities, and warehouses all have unique cooling and ventilation needs.
Key factors include:
-
Building size and layout
-
Number of occupants
-
Operating hours
-
Heat-generating equipment (e.g. kitchens, computers, machinery)
A professional load calculation ensures your system is sized for efficiency — not just capacity.
2. Choose the Right Type of System
There are several types of commercial air conditioning systems available in Brisbane, each with different advantages:
Ducted Systems
Ideal for large, open spaces or multi-room environments. Provide even airflow and quiet operation.
VRV / VRF Systems
Variable refrigerant systems offer precise temperature control and are highly energy-efficient — ideal for offices or mixed-use buildings.
Split or Cassette Systems
Good for smaller tenancies or specific zones where full-ducted systems aren’t practical.
Packaged Rooftop Units
Compact, efficient systems for larger facilities or industrial spaces.
Shelair designs and installs all major system types to match each client’s operational needs and budget.
3. Energy Efficiency and Running Costs
Energy efficiency isn’t just an environmental goal — it’s a major cost factor.
Look for systems with:
-
High star ratings or inverter technology
-
Zoning and smart controls
-
Demand-based ventilation
Modern commercial systems can reduce energy consumption by up to 30% compared to older models.

4. Maintenance Requirements
Some systems are easier and cheaper to maintain than others.
Ask about:
-
Filter access and cleaning frequency
-
Spare part availability
-
Manufacturer warranties
A cheaper upfront system can become more expensive long-term if maintenance is difficult or frequent.
5. Installation Quality Matters Most
Even the best system will fail to perform if installed poorly. Incorrect piping, poor duct sealing, or undersized electrical components can all lead to inefficiency and breakdowns.
That’s why choosing an experienced, licensed installer is critical.
At Shelair, our project managers oversee every installation stage to ensure compliance and quality assurance from start to finish.
6. Climate and Environmental Factors
Queensland’s climate — hot, humid, and often coastal — requires durable, corrosion-resistant systems.
Outdoor units near the coast benefit from:
-
Protective coil coatings
-
Stainless-steel fittings
-
Regular rinsing of salt deposits
Selecting a system rated for coastal environments extends lifespan and reliability.

7. The Importance of After-Sales Support
A good installation partner doesn’t disappear after handover.
