Ducted Air Conditioning Installation for your home

In addition to cooling, ducted refrigerated air conditioning systems can also provide heating during colder months. These systems use a reverse cycle process, where the refrigerant is reversed to provide warm air through the same ducts that distribute cool air.

This makes ducted refrigerated air conditioning a versatile and efficient solution for year-round climate control.

What Our Customers Are Saying

The whole installation and mains connection went seamlessly, with only a very small 'mains disconnect' period, which was great as my son is currently WFH and had a very small unavailability time with work. Very happy with the whole process, from quote to installation.

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.

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

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.

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.

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.

Jared came twice because we had a difficult set-up situation in a rear room with a box gutter. The solution worked out well.

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 !

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.

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.
