What Our Customers Are Saying

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 installers were exceptionally good. Understood the fragility of my ceiling and dealt with my threatening neighbour when they climbed on the roof on my side. The technician also gave me advice on how to keep the filters healthy and what setting to use. Thanks Coldflow.

I received a welcome email reminder that a service was due and made a booking date to suit. Your technicians contacted me the day before to confirm a time and they arrived on time as promised. The work was carried out efficiently by two young men, Steven and Hilo, who did so with courtesy and good humour. They are a credit to your business.

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.

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.

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.

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 !

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 weather was well and truly against them on the second day which made things really hard. But they were great. Thank you.

We'd highly recommend the team from Coldflow. Great communication, prompt and efficient installation and also great advice regarding the removal of our old gas wall heater. Not something we had considered but well worth it with the government rebate which we hadn't known about. Absolutely love our new Daikin unit too! Thanks 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.

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.

STEVEN crcic IS THE man !!!!! I have never had a better service in my life my girlfriend and I are so stoked he got the fan in the other room working.

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

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.

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.

I just had my two units installed. Please pass on my thanks to Jared Wates, who provided the quote, and the team that installed the systems today. The installation team worked really hard, double-checked, if not triple-checked, and certainly made sure things were clean when they left. A very professional and courteous team.
