What is Ducted Refrigerated Air Conditioning?

Ducted refrigerated air conditioning delivers whole-home comfort with precise temperature control.

Learn how Coldflow designs and installs these systems seamlessly.

Ducted air conditioning is one of the most effective ways to heat and cool your home. Unlike traditional split-system air conditioners, ducted air conditioning units circulate cooled or heated air throughout your entire home via a system of ducts rather than wall units in each room. This allows you to maintain a consistent temperature throughout your whole home, ensuring maximum comfort.

If you're interested in Whole Home Air Conditioning, ducted air conditioning is definitely worth considering.

Ducted Refrigerated Air Conditioning is effective in all weather conditions including humidity, making it perfect for Melbourne’s "4 seasons in one day". These units run on electricity using inverter technology, and are a whole - home solution that also provide heating as well as cooling.

Frequently Asked Questions About Ducted Refrigerated Air Conditioning

How Does Ducted Refrigerated Air Conditioning Work?

A condenser unit is positioned outside your home, connecting to a series of ducts that distribute the refrigerated air through your home.

Ducted Refrigerated Air Conditioning provides refrigerated heating and cooling throughout your Melbourne home with a comfortable temperature all year-round, regardless of the weather conditions. It does this while filtering the air and removing humidity.

Heating is provided economically by ‘reversing’ the operation of the air conditioner. Instead of expelling the hot air and circulating cool air, it does the reverse – hence the term ‘reverse cycle’ air conditioning.

What are the running costs with gas ducted heating?

One of our recommended brands for Ducted Refrigerated Air Conditioning is Mitsubishi Electric. For a Mitsubishi Electric PEAD-rp125jaa Series 12KW Ducted Refrigerated System, installed to provide a whole home regular heating & cooling during the winter and summer periods, the annual running cost would be measured at $1,340.05.

*Data is based on: 2016 Victoria Energy Tariff of 32.1 c/kWh, using a Mitsubishi Electric PEAD-rp125jaa Series 12KW Ducted Refrigerated 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 Ducted Refrigerated Air Conditioning Running Costs

It doesn’t take much to reduce your running costs with Ducted Refrigerated. 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 Ducted Refrigerated system can help as well.

Why Choose Ducted Refrigerated Air Conditioning?

Ducted refrigerated air conditioning provides quiet, unobtrusive climate control. Heat is distributed during winter, while cool air is circulated during summer. Coldflow is the leader for heating & cooling in Melbourne. Our qualified application engineers will advise you on the best system to fit any size requirement for home or business.

Inverter Technology

Inverter technology is your key to year-round comfort, whatever the conditions. By more precisely controlling the compressor rotation speed, this technology provides high-speed heating, cooling and comfort with extra energy savings compared to non-inverter models.

Our Recommendation

Our ducted residential heating and cooling systems are completely flexible, and can be customised for any application. We suggest you consider superior brands such as Mitsubishi and Daikin for their energy efficient advanced inverter technology.

My ducted air conditioning system was not working it had been installed by another company. I rang to try and get someone to diagnose my problem,on the same day a serviceman turned up and it was fixed for $275.00. Well worth it. Neil from Beaconsfield

I have always had very good service from Coldflow in the past and now at present and I would thoroughly recommend them to everyone who has airconditioning. As our house is relatively new at present, we are waiting to hear from the builders if our system is still under warranty, if it isnt we will certainly get back to you again.

The whole process was smooth from beginning to end. (Brian was Sales Rep). Good communication was provided via phone or txt msgs. The installer (Matt) was punctual, professional, polite, friendly, and a hard worker on a very hot day! A/c unit is effective, quiet and a slimline design. Thank You!

This is the second time we've used Coldflow, largely due to our positive experience the first time around. Sales process was quick and easy - very clear and helpful with advice and suggestions about what we needed. Installers were lovely - really polite, efficient and thorough. Cleaned up and explained everything. Will recommend to others.

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.

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.

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. My wife and I are very happy with the installation.

The young guy was very polite, knew what he had to do , and told me what he HAD done. BTW , I was the one that organized many of Braemar heaters to be installed here in my village. ( Waterford Valley Lakes) I would have thought that you would have organized ALL the other ones to be serviced at the same time as they are the same age.

Coldflow were great to deal with throughout the whole process. Communication was very good. Installers were on time, efficient and friendly. They moved furniture and picture on wall, put a sheet down over the carpet and left everything clean. Explained how to use the split system

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

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.

Relatively minor problem. Serge took due diligence and checked whole unit. May need a new stop valve in future. He explained how how well our 19yo unit is functioning and gave us thoughts on future possibilities. Obviously a very experienced technician and a real gentleman.

Coldflow recently removed our gas ducted heating and it replaced with a reverse cycle air conditioner. The process from quote to installation was simple and quick! Communication in the lead up to and on the day of installation was terrific. They also tidied up after themselves! I wouldn't hesitate to recommend Coldflow to family and friends.

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.
