What Our Customers Are Saying

Appointment was confirmed by email from office 10/4 pm but technician was booked for morning. When I was not at home when he phoned, he arranged to come back in the afternoon and do the job. Very helpful and he explained everything they had done and etc.

The Installers were punctual, and very courteous and helpful in explaining any questions I had. The installation went with no problems, all rubbish was removed and the site looked very tidy afterwards. The two installers worked well together and certainly did a great job

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.

Sorry I had forgotten the survey. All went well. Ray came as he said and went to work straight away. He left the area clean and tidy after explaining what he had done for the service. Will definitely look to Coldflow in two years time for the next service.

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.

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.

Everything went so smoothly. I had originally contacted few other companies for quotes however none of them called to book a time. Coldflow was the only company who called, was on time with everything and was very professional. From sales to Installation it went great.

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.

Courteous serviceman with professional attention to his job. Easy to book. Fair cost for service rendered. (A competitor outfit required pre-payment for the service call, about $150, and then quoted a price of $2,000 for the same work. He was quickly escorted off the premises.)

It was explained well about the ducted heating tests. Also the air grill needed replacement but the heating system was old and it may have been difficult to replace. It was fixed so it was not falling down all the time. The office rang to explain another option. However I was happy with the outcome. Thankyou

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.
