Single Head Split System Installation Melbourne
Supply and Installation by a Licensed Refrigeration Technician
A single head split system is the most popular and cost-effective way to heat or cool a room in a Melbourne home or business. Pergz Air supplies and installs single head split systems across Melbourne, sized correctly for your space and installed neatly by a licensed refrigeration technician.

What Is a Single Head Split System?
A single head split system connects one indoor wall unit to one outdoor compressor unit. Refrigerant lines run between the two through the wall, allowing the system to heat and cool the space efficiently without ductwork or major building work.
Modern reverse cycle single head systems do both heating and cooling in one unit, making them a practical year-round solution for Melbourne’s climate. Cool in summer, warm in winter, controlled from a remote or smartphone app depending on the model.
What the Installation Involves
Site Assessment
We start by assessing the room. That means looking at the size, ceiling height, insulation, window placement, sun exposure, and how the room is used throughout the day. We also assess the best position for the indoor unit and the most practical pipe run route to the outdoor compressor.
Getting this right before a unit goes on the wall makes a real difference to how well the system performs and how clean the finished installation looks.
System Selection
We recommend the right capacity unit for your specific space based on the assessment, not a rough estimate based on floor area alone. Correct sizing is one of the most important factors in split system performance. Too small and the system runs constantly without reaching temperature. Too large and it short cycles, wearing out faster and delivering inconsistent comfort.
We’ll walk you through the unit options that suit your space and budget and help you make an informed decision without any pressure.
Installation
On the day, we mount the indoor unit in the agreed position, install and connect the outdoor compressor, run the refrigerant pipe and electrical connections, and conceal pipe runs where possible for a clean finish. Penetrations are sealed properly and the work area is left tidy when we’re done.
Most standard single head installations are completed within two to four hours.
Testing and Handover
Before we leave, we test the system in both heating and cooling modes to confirm everything is running correctly. We walk you through the controls, explain the settings, and make sure you’re comfortable using the unit before we pack up.
Is a Single Head System Right for You?
A single head split system is the right choice when you need reliable climate control in a specific room or area without the cost of a multi head or ducted system.
They work well in:
- Bedrooms and master suites
- Living rooms and open plan areas
- Home offices and studies
- Apartments and units
- Granny flats and secondary dwellings
- Small offices and commercial spaces
- Garages and workshops
If you need climate control across multiple rooms, a multi head system or ducted air conditioning may be a better fit. We’ll give you an honest recommendation either way.
Getting the Sizing Right
Sizing is where a lot of split system installations go wrong. Too many installers default to a standard capacity without properly assessing the space, which results in a system that either struggles to reach temperature or short cycles and never runs efficiently.
At Pergz Air we calculate the right capacity based on:
- Room size and ceiling height
- Insulation in walls, ceiling, and floor
- Window size, glazing type, and orientation
- Sun exposure on different sides of the room
- How the room is used and how many people typically occupy it
We’ll explain our recommendation clearly so you understand exactly why we’ve suggested a particular unit before you commit to anything.

Frequently Asked Questions
What size unit do I need for my room?
It depends on room size, ceiling height, insulation, window placement, and sun exposure. We calculate this properly during the site assessment and explain our recommendation before you decide on anything.
Can a split system be installed in any room?
In most cases yes. The key considerations are access to an external wall for the pipe run and the distance to the switchboard for the electrical connection. We assess both during the quote and flag any complications upfront.
Do single head split systems heat as well as cool?
Yes. All modern reverse cycle split systems both heat and cool, making them a practical year-round solution for Melbourne's variable climate.

It depends on the unit selected and the complexity of the installation. We provide clear, upfront quotes so you know exactly what's involved before you commit. Get in touch for a free quote tailored to your home.
What warranty is included?
All units come with manufacturer warranty and our installations are completed to current Australian Standards. We'll walk you through the warranty details for your chosen unit during the quote.
How often should I service my split system?
We recommend servicing your split system once a year to keep it running efficiently, maintain manufacturer warranty requirements, and catch any developing issues before they become more costly problems.
