Our Professional Services

Expert Installation

Setting up a multi head split system requires careful planning. We need to make sure the pipes and wires are hidden away neatly and that the outdoor unit is powerful enough to handle all the rooms at once. We look at your home’s layout and help you decide the best spots for each unit to get the best airflow.

Reliable Servicing and Care

Because these systems work hard to cool multiple areas, regular maintenance is important. We provide a full service that includes cleaning the filters, checking the refrigerant levels, and ensuring the outdoor motor is running efficiently. Keeping your system clean helps it last longer and keeps your air fresh.

Why Choose a Multi-Head System?

A split system aircon multi head setup is a fantastic alternative to a full ducted system, especially if you don’t have much space in your roof.

Save Space: You only need one outdoor unit instead of three or four cluttering up your backyard or balcony.
Control Each Room: You can turn off the air in the guest room while keeping the main bedroom cool, which is great for your power bills.
Versatile: You can choose different styles or sizes of indoor units to suit the specific needs of each room.

Frequently Asked Questions

Most quality systems last between 10 and 15 years with proper care. Regular servicing and timely repairs can help maximise lifespan. Usage frequency and environmental conditions may also affect longevity.

Townhouses often have limited outdoor space and multiple levels requiring separate climate control. A multi-head system addresses both challenges by using one outdoor unit while serving multiple rooms. This makes it a practical solution for compact properties.

The cost depends on the number of indoor units, system size, and the condition of the equipment. Larger systems generally require more servicing time than standard split systems. A technician can provide an accurate quote after assessing the system.

Many upgrade to gain greater flexibility, improve comfort, and reduce the number of outdoor units around the property. Independent room control is another major reason. These systems offer a practical balance of efficiency and convenience.

Most multi-head split system services take between one and three hours, depending on the number of indoor units connected. The technician will inspect, clean, and test each unit to ensure it is performing correctly. Larger systems may require additional time.

Water leaks are often caused by blocked condensate drains, dirty filters, or drainage issues. If moisture cannot drain properly, it may overflow from the indoor unit. Professional servicing can identify and resolve the source of the leak.
