What Our Customers Are Saying

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.

Everything was done very professionally by all team members. They even clean up the outside of my property, however they could have done a little better with the clean up of the inside. On the whole, I am very pleased with the installation. Thank you.

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!

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.

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 was very impressed with the professionalism and tecnical knowledge of the sales rep. I was sold exactly the right product with the best price and an extened warranty. I am very pleased as I was interstate when the heater broke and my daughter was the only person at home.

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.

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.

MICHAEL A.

DINGLEY VILLAGE

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.

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.

We had so much trouble getting information and things booked in with other companies but Coldflow were just wonderful!! We cannot thank you all enough for getting on to things so quickly for us. Communication excellent and overall a fantastic service! Can highly recommend.

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.

CHELTENHAM

August 2024

Jared, Lucas and Luke were all very professional, friendly and courteous. We were very impressed with the communication and all were on time for scheduled appointments. They were all just really easy to deal with, we'd definitely recommend Coldflow.

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.

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!

Installation completed earlier than anticipated, which was greatly appreciated. The installer arrived at the notified time, and completed the installation and instruction of how to operate the the cooler in an extremely efficient and friendly manner.

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.

Keith G.

HAMPTON PARK

February 2023

Organised for the team to come out and assess the in laws heating and cooling. There were 6 systems in total. All were checked and reports received. Services conducted on the systems worth keeping and advice given re the others, allowing informed decisions to be made. Highly recommended.

LINA S.

MOOROOLBARK

July 2024

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.

DAVID R.

Great service explained everything as they went. Friendly service. Wiped shoes on entering the home. Great to see the apprentice being taken under the wing of an experienced person who was very good at explaining and questioning the apprentices understanding.

IVANHOE EAST

The complete process from quotation with Craig to the installation yesterday was a great experience. We would have no hesitation in recommending Coldflow to family and friends. We were actually told about Coldflow by my stepson and his partner in Koo Wee Rup.

HAMPTON PARK

August 2024

The engineers were very friendly and professional. They went out of their way to listen to me as a customer. The quality of their work was top-notch: they knew exactly what to do and they expertly installed the air con devices. Would definitely recommend ColdFlow to my friends and family.

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.

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!!

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.

GRAEME C.

DONCASTER EAST

February 2022

very good installation except for electrician not turning up on the day. He did come the next day though. The unit is working very well as i needed it to replace an aging gas wall heater. I would recommend Coldflow company to anyone interested in this kind of product.
