What is a Split System Reverse Cycle Air Conditioner?

Split systems come in a huge range of capabilities and designs. The most commonly recognised and installed split systems are wall-mounted units with fan coils (otherwise known as evaporators). Wall-mounted split systems are commonly used in houses and apartments as there is only a requirement for two parts to be installed; the indoor unit and the outdoor unit.

Split systems are generally a straightforward install, especially when compared with something like an Evaporative Cooling system where duct and vents need to be installed throughout the entire home.

Frequently Asked Questions About Split System Air Conditioning

How Do Split Systems Work?

Split air conditioning systems have their name due to half the system (condenser) being outside the house while the other half (fan coil) is installed inside. When cooling, the warm air from inside the room is taken in by the fan coil and removed, resulting in cool air recirculating back into the house. While reverse cycle allows for the heat pump to run in reverse to provide heating during cold days.

Split air conditioning systems can be fitted to individual rooms, areas or multiple rooms connected by copper piping to an outdoor unit (condenser). Multi-head split air conditioning systems can be installed for up to nine rooms with only one outdoor unit, and allowing for individual temperature control of each room.

What Are The Running Costs With Split Systems?

One of our recommended brands for Split Systems is Mitsubishi Electric. For a Mitsubishi Electric GE Series 2.5KW Split System, installed in a small room providing regular heating & cooling during the winter and summer periods, the annual running cost would be measured at $272.34.

*Data is based on: 2016 Victoria Energy Tariff of 32.1 c/kWh, using a Mitsubishi Electric Single Small Sized Room 2.5KW Split System collected from Sustainability Victoria’s Energy Consumption and Running Costs website. Usage times were set on average to 4 months of heating, and 2 months of cooling based on 7 hours a day. Actual running costs are affected by many factors including climate and insulation; this data should only be used as a guide and does not guarantee your individual running costs will reflect these results.

Reducing Split System Running Costs

It doesn’t take much to reduce your running costs with a Split System. Depending on the model you purchase, and it’s respective star rating will determine how much you can save annually. However looking beyond the initial cost to how you use your Split System can help as well.

Smarter Choice, Save Energy Water and Money

Tips For Using A Split System

Best Tip! Set the thermostat between 24C and 26C for cooling. Every degree lower in summer will increase the running costs by around 10%.

Use the economy setting if your split system has one and regularly service your air conditioner.
Keep the sun’s heat out by closing curtains and external blinds during the day. Close windows and doors to areas being cooled when the split system is running.
When the split system is switched off and its cooler outside, open doors and windows to let the cool air in.
Insulate your home to keep the heat out in summer and in during winter.
Dress to suit the weather conditions.

Why Choose Split Systems?

Wall mounted split air conditioning systems are the most commonly owned residential air conditioning system, as they are affordable and easily to maintain.

Inverter Technology

Inverter technology is your key to more comfort throughout the year as it maintains a constant temperature, saves costs (less energy consumption) and produces relatively less noise when used. This is achieved through controlling the compressor rotation speed more precisely.

Affordable

Wall mounted split AC systems are the best affordable option for a one room, apartment or small house as they are relatively cheap to buy (depending on how many indoor units you require) and there is no duct work required.

Independent Temperature Control

Each indoor unit is able to control the room that it is installed in, thus each room can have a different temperatures.

Air Quality

Many split air conditioning systems have air filtering and humidity control functions that regulate the amount of dust and humidity in a room. This gives sensitive customers (children, elderly, asthmatic or allergic users) an ease of mind and body.

Multi-Head Split Systems

Multi-Head Split Systems allow different indoor units to connect to one outdoor condenser, which in turn gives you the comfort of having the most suitable air conditioner (in terms of physical and output constraints) for a specific room.

Everyone involved in this was great. Ash and Terry who did the installation did a terrific job with a lot of attention to detail. And we really appreciate the work they put in.

The two technicians were well mannered, presented well as representative of your company and did a good job explaining what they had done in terms of the service of our gas heater. They were polite, arrived when they said they would which is important given we work form home and have work commitments. Great ambassadors for your company.

Great friendly service. Chris called beforehand and arrived between times we were given - checked unit was running safely and as well as it could (given age) and ensured it was safe to continue using. He also gave great advice regarding updating the unit. Customer service from booking to followup was fantastic. Well done Coldflow !

Darren Storey - Professional, knowledgeable, easy to deal with. Adam scheduled the installation promptly and then it happened a week earlier - great. Installation crew lead by Jason - fast, efficient, timely - considering the wet weather throughout the morning and hopefully all has been done properly.

Team did a great job, install team had to vary the installation location of parts, access etc, vs. communicated during the sales process. This is fine, just a note that worth getting feedback from your install team to your sales team to help future customer comms. The team kept the site clean and took away all rubbish which was great

CHARLIE H.

Prompt and good communication in letting customers know when they are about to arrive. They do and communicate what was done in service. Any questions are answered and I like the professionalism of turning up in a company named work vehicle and uniform. Also the payment method is trusted with a receipt on the email

Chris Didcock was very friendly and reassured me that the issue would be rectified. However, our heater went back to fault mode after Chris left. As promised, Chris came first thing in the morning and reset the heating unit after being in contact with the manufacturer about the error code.

Darren Story was very helpful with the initial site visit, he explained clearly how the installation would run, and gave us the options. Ash and his team did a highly professional job with the installation, and I am thankful that they wore masks as my mum was home recovering from surgery. A brilliant job all round, thank you very much.

Ray did an excellent job. As it turned out, the error that caused the problem was cleared when the power was off after the storm, but he still made sure the system was working properly by doing a really thorough check of everything. Very helpful, professional and clearly very keen to make sure the job was done properly. Great work!

We would have liked to be given the option whether to have the smelly chemicals sprayed in the split systems, as the smell lasted for over a week and we would have opted not to have that. Otherwise we are very happy with the overall service and communication from the technician.

Jared came twice because we had a difficult set-up situation in a rear room with a box gutter. The solution worked out well. David and Daniel were professional and friendly installers who installed without fuss or mess. Sparky (Harold) was also efficient and easy to communicate with.

Very likely, your team arrived on time. They worked quickly and efficiently, plus they were very friendly. They left our house as they found it , clean and tidy. Just one thing they left behind a piece of equipment which I'm sure they can use. It is no use to us, so it would be a shame to throw it out. Many Thanks.
