Why a split system suits most Melbourne homes

Split system air conditioning installation in Melbourne is the default for good reason. You get reverse cycle heating and cooling in the room you actually use, for a fraction of the cost of a whole-house system, and a modern inverter unit is quiet enough that you forget it is running.

Melbourne's climate plays to the strengths of reverse cycle. Our winters are cool but rarely brutal, which is exactly where a heat pump is at its most efficient — delivering roughly three to five units of heat for every unit of electricity. That makes a split system one of the cheapest ways to heat a Melbourne room, not just cool it.

Supply and install, start to finish

We supply the unit and install it with our own licensed team — you are not buying a box from a retailer and hunting for an installer. Every split system supply and install includes:

  • The indoor and outdoor unit, supplied new with full manufacturer warranty
  • Wall bracket or ground pad for the outdoor unit, and a standard back-to-back pipe run
  • Pressure testing and vacuuming of the pipework by an ARC-licensed technician
  • Electrical connection certified by our registered electrical contractor (REC 27289)
  • Removal of your old unit if there is one — see new for old replacement
  • Handover, controller set-up and all packaging taken away
  • A compliance certificate issued on completion — with every job

Where split systems work best

  • A main living area you want comfortable year-round without heating the whole house
  • Bedrooms, especially for sleeping through February heatwaves
  • Home offices, studios and converted garages
  • Rentals and units where a single-room solution is all that is permitted
  • Replacing an old, noisy or failing wall unit like-for-like

Buying advice

Choosing the right unit

Three things worth understanding before you compare quotes.

Inverter vs non-inverter

An inverter ramps its compressor up and down to hold temperature instead of switching hard on and off. It costs more up front, uses noticeably less power, and is far quieter. We install inverter units almost exclusively.

Star ratings and running cost

Compare the zoned energy rating label, not just the headline stars. In Melbourne you care about the heating rating for the cool zone as much as the cooling rating — you will use heating more hours of the year.

Noise ratings

Check the outdoor sound power level if the unit sits near a bedroom or boundary. A few decibels is the difference between unnoticeable and a standing complaint.

Efficient timely and expert installation of our Mitsubishi split system. So much better for health and pocket than cumbersome gas ducted heating. Thankyou
