What to Expect from a Multi Head Split System Install

Getting the right cooling in before the heat settles can make a big difference in how you enjoy the season. For homes with more than one key area to cool, a multi head split system installation can be a smart pick. These systems offer the flexibility to cool more than one zone without needing multiple outdoor units or bulky ductwork. Instead of scrambling during a heatwave, it is worth knowing what to expect from the beginning. Planning ahead helps prevent surprises and gives you a clearer idea of how things should unfold.

Choosing the Right System for Your Home
A multi head split system is built around one outdoor unit connected to several indoor heads via slim piping and wiring. It runs quieter than older systems, does not need big ceiling spaces for ductwork, and gives you better control over each zone. This setup suits households where different rooms get used at different times, or where family members want to keep their own space cool.

Start by looking at your home’s layout. The number of indoor units you need depends on the rooms you want to cool and their size. For families with kids or home offices, one unit in each bedroom and a larger one in the lounge or living area could be ideal.

Unit placement really matters. Indoor heads should be set high on the wall for good airflow but spaced so they are not directly aimed at beds or work spaces. Make sure nothing is blocking them—no heavy curtains, bookshelves, or wall art. Avoid big temperature swings between rooms, and keep units out of corners where airflow can be trapped.

AGA Air Conditioning supplies and installs a wide range of split systems and multi head options across Canberra, helping homeowners plan placements and system sizing to suit each unique floor plan.

Getting the House Ready Before Install Day
A little prep before the team arrives helps speed everything up on installation day. Start by clearing furniture, shelving, or anything hanging on the walls where the units will go. Indoor units need a safe space to be mounted, and there should be easy access to power and drainage.

Check the space outside for the main outdoor unit. It needs airflow and a firm, flat base (slab, pavers, or wall brackets), well away from obstacles. Trim back shrubs and make sure pets will not be in the way.

Think about your power supply as well. Older homes with outdated switchboards or limited capacity may need an upgrade or assessment before installation. AGA Air Conditioning can assess your meter box and talk through any changes required to support the new system.

Ask your installer:

- How many technicians are coming?

- How long do they expect the job to take?

- Do you need to be out of the house or off work calls during noisy moments?

Installation Day: What Actually Happens
On installation day, the installer will double-check the planned layout, finalise indoor head locations, and check for any last-minute concerns. They will drill or cut holes for the pipes and cables, then mount each indoor unit, making sure it is secure and has the right spacing.

The outdoor unit will be set up on its base or brackets, well away from places where airflow could be blocked. Pipes and wiring get fed and connected to the outdoor compressor. Once everything is in place, technicians will wire the system, check all connections, and run system start-up tests.

Most installs take a day, but it can run longer depending on the number of heads, wall types, and weather. Three or four heads in a large double-storey home might push the job into a second visit, especially if outdoor access is limited.

Before leaving, installers will walk you through:

- Remote controls and mode options

- Filter locations and basic cleaning tips

- Common alerts and what to do if something feels off

Post-Installation Check and Tips for First-Time Use
Before the crew leaves, walk the whole house and test every indoor unit. Ensure each one powers on, responds to control inputs, and disperses air in the right direction. Feel around for even airflow, and listen for any buzzing or rattling.

Check how drainage lines carry away condensation, and look for any damp patches on walls or outside the home. Outside, make sure the compressor is running quietly, without strong vibration or wobble.

Plan to run your system gently for half an hour on a moderate day to make sure everything works. Switch between cool and fan modes and learn how quickly each area cools down. Early on, keep doors closed to help air stay in each zone.

For handy early maintenance:

- Rinse indoor filters every few weeks, especially over summer

- Vacuum or brush around head units to clear dust on vent fins

- Keep the outdoor area free from garden debris or pet hair

Using the zoning features lets you save power by cooling the areas you use most, not the entire home at once.

Staying Cool the Smart Way
A multi head split system installation offers a simple, effective way to keep every corner of your Canberra home comfortable, no matter how varied your family’s schedule or space. Each person can cool their own area or switch off units in places that are not being used without losing comfort elsewhere.

Planning with clear advice from experienced installers, combined with a little prep and a good initial test, takes the mystery out of summer comfort. Enjoy flexibility, lower running costs, and long-term peace of mind—all with a system that fits the way you really live.
