What is a Multi-Split Air Conditioner?
A multi-split air conditioner connects multiple indoor units to a single outdoor unit, providing customized temperature control for several rooms simultaneously. Unlike a standard split system, which serves one space, a multi-split system allows for individual climate settings in each room, making it an ideal solution for larger homes and offices.
Multi-split Airconditioning
How does a Multi-Split System work?
Using refrigerant lines instead of bulky ductwork, the outdoor compressor delivers cooling or heating to each indoor unit through a vapor compression cycle. This process ensures efficient temperature regulation across different areas while maximizing space and energy savings.
Key Benefits of Multi-Split Systems
Individual Temperature Control
Set different temperatures in each room for personalized comfort.
Space Efficiency
A single outdoor unit powers multiple indoor units, saving space and reducing outdoor clutter.
Energy Savings
Advanced inverter technology adapts compressor speed to minimize energy use while maintaining optimal performance.
Flexible Design
Choose from various indoor unit styles—wall-mounted, ceiling-mounted, or floor-standing—to suit your interior design.
Benefits
Is a Multi-Split System right for You?
Multi-split systems are perfect for households or businesses that need zoned climate control without the complexity and cost of installing separate systems for each room. Whether it’s cooling a bedroom while heating a living area, a multi-split system provides flexibility, comfort, and energy efficiency in one comprehensive solution.
Factors that affect the cost of Multi-Split System Installation
The cost to supply and install a multi-split system varies based on several factors, typically ranging from $3,000 to $6,000 (including GST), depending on the complexity of your setup and preferences. Key considerations include:
Number of Indoor Units
Each additional unit increases both equipment and labor costs.
Indoor Unit Location
Installing units on external walls simplifies installation. Internal wall setups may require extra piping, drainage pumps, and structural modifications.
Distance Between Indoor and Outdoor Units
Longer refrigerant lines, cables, and more refrigerant increase material and labor expenses.
Condenser Placement
Ground-level installations are straightforward. Rooftop or elevated placements involve additional brackets or platforms, impacting cost.
Electrical Supply and Switchboard Location
The complexity of running a dedicated power circuit depends on the proximity of your switchboard to the outdoor unit.
System Brand and Features
Advanced models with smart technology or premium features influence the final price.
