Air Conditioning in Melbourne, done the easy way
Cooling that actually matches your home, not an oversized unit that short-cycles or an undersized one that never catches up.
SG Aircon installs, repairs and services split-system and ducted air conditioning for Melbourne homes. We size the unit to your room, orientation and insulation, then install it tidily and show you how to run it efficiently.
✅ Rebate-eligible upgrade. We apply your Victorian government rebate to the quote and handle a fully compliant install as direct installers. See rebates →Signs it's time to call about cooling
- The unit runs all day but rooms never reach the set temperature
- Warm or musty air, ice on the pipes, or water dripping inside
- Loud rattles, grinding or a burning smell when it starts up
- Power bills climbing while cooling performance drops
- An ageing system using phased-out R22 refrigerant
What affects your aircon quote
No one-size-fits-all pricing. Here's what shapes an honest quote:
Single vs. multi-head vs. ducted
More indoor zones and ductwork mean more material and labour.
Indoor/outdoor unit distance
Longer pipe runs and tricky outdoor mounting add time.
Electrical readiness
Some installs need a dedicated circuit or switchboard work.
Removal of an old unit
Safe degassing and disposal of the existing system.

More about air conditioning in Melbourne
A 40°C Melbourne day is the wrong time to discover your air conditioner can't keep up. Whether you want a single split system for a bedroom, a multi-head setup for the living zones, or full ducted cooling for the whole house, the difference between a comfortable summer and an expensive disappointment is almost always sizing and placement, not the brand on the box.
Repair, replace or upgrade?
If your system is under about eight years old and the fault is a capacitor, sensor or gas top-up, a repair is usually the sensible call. Past ten years, or facing a compressor failure, replacement with a high-efficiency inverter unit often pays for itself in running costs within a few summers. We give you both numbers and let you choose; there is no commission pressure to rip and replace.
Systems we work with
We install and service reverse-cycle split systems, multi-head systems and ducted air conditioning from the major Australian-supported brands. Reverse-cycle units double as efficient winter heating, which is why we often recommend them over cooling-only models for Victorian homes.
Victorian seasonal note
Book installs in spring or autumn if you can. Demand spikes the first week the forecast hits the high 30s, and that's when lead times and prices are worst. A pre-summer service in October keeps an existing system reliable through the peak.
Air Conditioning FAQs
What size air conditioner do I need?
As a rough guide, allow about 0.125–0.15 kW of cooling per square metre of floor for a well-insulated room, then adjust for ceiling height, west-facing windows and Victorian summer extremes. We confirm the exact figure with an on-site measure-up before quoting.
Split system or ducted, which is better?
Split systems are cheaper to install and ideal for cooling one or two rooms. Ducted suits whole-home comfort and a cleaner look, at a higher upfront cost. If you only live in a couple of zones, several splits often beat one big ducted system on running cost.
How long does an installation take?
A standard back-to-back split system is usually done in a few hours. Multi-head and ducted installations can take one to two days depending on the run lengths and access.
Can you fix my existing air conditioner instead of replacing it?
Often yes. Many call-outs are a failed capacitor, blocked drain, dirty filter or low refrigerant, all repairable. We always quote the repair before suggesting replacement.
Do you remove and dispose of the old unit?
Yes. We safely recover the refrigerant and remove the old indoor and outdoor units as part of a replacement install.
