Ducted or Split Systems? The Best Choice for Your Commercial Space

February 19, 2025

Creating a comfortable indoor environment is essential for any business, whether it’s an office, retail store, restaurant, or industrial space. With various commercial air conditioning options available, it’s important to select a system that suits your specific requirements for efficiency, scalability, and cost. Two of the most common systems are ducted air conditioning and split systems. Here's a guide to help you decide which solution works best for your business.

Ducted Air Conditioning: Ideal for Larger Commercial Spaces

Ducted air conditioning systems are designed for whole-building temperature control. A central unit cools or heats the air, which is distributed through concealed ducts to multiple zones or rooms.

Why Choose Ducted Air Conditioning for Your Business?

  1. Whole-Building Climate Control
    Ducted systems are perfect for businesses operating across multiple rooms or larger open-plan spaces. They provide uniform temperature control, creating a consistent and professional environment for staff and customers.
  2. Zoning for Flexibility
    Zoning options allow you to control the temperature of specific areas, such as offices, meeting rooms, or reception areas. This can reduce energy usage in areas that are not in constant use.
  3. Discreet Installation
    With ducts hidden in ceilings or walls, ducted systems maintain a clean and streamlined look, ideal for modern office spaces or high-end retail environments.
  4. Customisable Solutions
    These systems can be tailored to meet the specific needs of your building size and layout, whether it’s a multi-level office or a large showroom.

Best Applications

  • Office buildings
  • Retail outlets
  • Hospitality venues such as hotels and restaurants
  • Warehouses or large industrial facilities

Considerations

  • Higher Installation Costs: Requires significant investment upfront due to ductwork and centralised equipment.
  • Maintenance: Regular maintenance is essential to keep the system running efficiently.

Split Systems: Cost-Effective and Flexible

Split systems consist of an indoor unit and an outdoor compressor, designed to cool or heat individual areas.

Why Choose Split Systems for Your Business?

  1. Budget-Friendly Installation
    Split systems are easier and more affordable to install compared to ducted systems, making them suitable for businesses with smaller spaces or tighter budgets.
  2. Individual Area Control
    Ideal for spaces where specific areas require different temperatures, such as a single office, a customer lounge, or storage rooms.
  3. Energy Efficiency for Small Areas
    Split systems are highly efficient for cooling or heating individual rooms, avoiding unnecessary energy consumption in unused spaces.
  • Quick Installation and Scalability
    Adding additional units is straightforward, making it a great solution for businesses that plan to expand or adjust their layout over time.

Best Applications

  • Small to medium-sized offices
  • Cafes or restaurants with separate dining and kitchen areas
  • Boutiques and small retail spaces
  • Clinics and consulting rooms

Considerations

  • Visible Units: Indoor units are wall-mounted, which may not suit businesses prioritising aesthetics.
  • Limited Coverage: Not ideal for large spaces requiring centralised control.

Choosing Wisely: Essential Factors for Commercial Air Conditioning

  1. Size of Your Business Space
    Large buildings benefit more from ducted systems, while smaller businesses or segmented spaces can efficiently use split systems.
  2. Energy Efficiency Goals
    Ducted systems with zoning capabilities and energy-efficient split systems can both reduce operational costs. Evaluate your energy consumption needs to find the right fit.
  3. Aesthetic Preferences
    For client-oriented businesses, having a discreet ducted system might enhance your professional image.
  4. Budget
    Split systems are cost-effective for installation and are ideal for smaller budgets, while ducted systems are an investment in long-term efficiency for larger spaces.
