The Salesman Craig who came to our home was very friendly, helpful and efficient. It was easy to pay the balance of our order at the Showroom. The two instillation guys who came to our house were also very friendly, helpful and efficient. Overall an enjoyable experience and now we are toasty warm

First of all, the communication was consistent and timely - I always knew where we were up to. On the day, the installation team were fast and efficient and you would not have known work had been done. Similarly, the electrician worked fast and clean. We are really happy with the process and with our new aircon units.

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.

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.

An excellent experience. The online was simple and efficient. The call out team were on time, clean uniforms, friendly and polite. Their work was excellent. Everything was made clear. I honestly couldn't fault my dealings with your firm, you should be very proud of the work you must have done to achieve this standard.

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.

The 5 boys who attended my house to install the heating and cooling were exceptionally professional. They catered for all my requests and nothing was too much to ask. From the quote to the final payment-I cannot recommend you enough. The experience was easy, everyone was easy to get along with and extremely helpful. Thank you!

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.

The team of installers did a fantastic job. We couldn't believe how quick they were in completing the installation of our new air conditioning system. I wouldn't hesitate to recommend Coldflow to friends or family if they require an air conditioner installed.

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!

This is the second time we have had Coldflow at our house. Each time the quotes were competitive. The installers arrived on time and were super efficient removing an old device and installing the new unit. Thanks to the team especially Nick and the electricians

From quote to install went very smoothly. Appreciated the honesty to offer the VEEC rebate as part of quote - other companies gave quotes that did not show this rebate and most likely would pocket the extra themselves. Even the Installation team turned up earlier than expected and did a very professional job. Thanks.

Fantastic service both in regards to receiving the quote (the man sent out seemed to be very knowledgeable and helpful in providing advice on what would work) as well as the installers, who were timely, friendly, knowledgeable and professional in their installation of our split systems :) very very happy with the service we received!!

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 Installers, Dave and his two assistants were very organised, planning and executing every part of the installation with precision never wasting a moment. They worked as a professional team always anticipating the next move. Dave's leadership and experience ensured a smooth fit out and a top job. I highly recommend him. They cleaned up too.

Very glad and relieved I chose Coldflow. Your installer Murray arrived at 7am Monday 21st, was quickly to work with a minimum of fuss. Old Brivis unit and new Braermar unit out and in through the roof. All over by 9am. He showed us how to use the Braemar control unit before leaving. Great job.

I have already recommended Coldflow to two other friends/family who are considering AC upgrades. With this installation, the only glitch was the rescheduling due to our household being close contacts for COVID. Once that was out of the way, it all went smoothly.

Once again Brodie excelled and organised a technician to come straight out to tend to a minor issue. No questions asked just great customer service as always. I highly recommended Brodie and the team at ColdFlow. After using them for the first time a few years ago we would not go anywhere else. A huge 'thank you' to everyone at ColdFlow ??

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.

Installation crew lead by Jason - fast, efficient, timely - considering the wet weather throughout the morning and hopefully all has been done properly.
