Factors Influencing the Cost

Several factors can impact the final cost of your Daikin ducted reverse cycle system installation. Understanding these can help you better estimate your potential expenses.

1. Size and Layout of Your Home

The size and layout of your property can significantly influence the cost of installation. Larger homes or those with complex layouts may require more powerful units and additional ductwork, increasing the overall cost.

2. Number of Zones Required

Zoning allows you to control the temperature in different areas of your home independently. While this feature enhances comfort and energy efficiency, each additional zone adds to the system’s cost.

3. Brand and Model of the System

Daikin offers various models with different features and capacities. Premium models with advanced features will naturally cost more than basic ones.

4. Complexity of Installation

The difficulty of the installation process can affect the cost. Factors such as ease of access to roof spaces, the need for additional electrical work, or complex ductwork installations can increase labour costs.

5. Ductwork Requirements

If your home doesn’t have existing ductwork, or if the current ductwork needs replacement, this will add to the overall cost of the project.

6. Energy Efficiency Rating

More energy-efficient models may have a higher upfront cost but can lead to significant savings on energy bills in the long run.

7. Additional Features

Features such as smart controls, air purification systems, or humidity control can add to the system’s cost but may provide added value and comfort.
