Split System Air Con Installation Melbourne East

Supply, Install & Set up

A split system air conditioner is the most popular cooling and heating solution for Melbourne homes — versatile, efficient and cost-effective to run, and well suited to a single room or an area where extending existing ducted heating isn't practical. The Heater Repairman supplies and installs split system air conditioners across Melbourne's eastern, southeastern and northeastern suburbs, helping you choose the right system for your space and installing it professionally so it performs at its best from day one.

Signs you need this service

You have a room or area of the home with no cooling or heating — a split system is the most cost-effective fix
Your existing split system is over 10 years old and running inefficiently, driving up electricity bills
Your current unit is no longer cooling or heating effectively even on a low-medium setting
You've recently added a room extension or converted a garage and need a climate solution
Your existing unit is producing unusual noises, dripping water inside, or producing a musty odour
You want a reverse-cycle system that both cools in summer and heats efficiently in winter
You're preparing to sell or rent and want to add a climate comfort feature to the property
You're replacing a ducted gas heater and want a modern, energy-efficient heating and cooling solution

Getting the sizing and placement right

The single biggest factor in how well a split system performs day to day isn't the brand — it's whether it's correctly sized for the room. An undersized unit will run constantly and struggle to reach a comfortable temperature, while an oversized unit cycles on and off too frequently, which is both less efficient and less comfortable due to temperature swings. Sizing depends on the room's floor area, ceiling height, insulation quality, window size and sun exposure, not just square metres alone. Outdoor unit placement matters too — for noise, for airflow efficiency, and for how far the pipe run needs to travel between indoor and outdoor units, which affects both installation cost and ongoing performance. We assess all of this on-site before recommending a specific unit rather than sizing off a generic room-size chart.

Frequently asked questions

What size split system do I need for my room?

The right size depends on the room's dimensions, ceiling height, insulation and sun exposure. As a guide, a 2.5kW unit suits rooms up to 20m2, a 3.5kW suits 20–35m2 and a 5kW–7kW suits larger rooms. We'll assess your space and recommend the right size.

Which split system brand do you recommend?

We supply all major brands including Mitsubishi Heavy Industries, Daikin, Fujitsu, Panasonic and LG. All are reliable performers - the best choice depends on your budget, features required and the specific room. We'll guide you through the options.

How long does split system installation take?

Most single-split system installations are completed in 3–4 hours. Multi-room installations take longer. We'll give you a clear timeframe when you book.

How much does split system installation cost in Melbourne?

Installation cost depends on the unit size, installation complexity and any additional requirements like long pipe runs or roof space work. Call 0433 547 007 for a quote tailored to your home across Melbourne East.

Can a split system both heat and cool?

Yes - modern split systems are reverse cycle, meaning they both cool in summer and heat in winter. They're highly energy efficient for both functions, making them a year-round home comfort solution.

Does outdoor unit placement really make a difference?

Yes — placement affects noise levels for you and neighbours, airflow efficiency, and how far refrigerant piping needs to run, which impacts both installation cost and long-term performance. We assess this properly on-site.

What areas do you cover for split system installation?

We service Melbourne's eastern, southeastern and northeastern suburbs including Ferntree Gully, Knox City, Boronia, Bayswater, Ringwood, Dandenong, Glen Waverley, Doncaster and surrounding areas.

Do I need council approval to install a split system?

Generally no for a standard residential installation, though strata or body corporate properties may have their own rules on outdoor unit placement. We can advise if anything specific applies to your property.
