What Our Customers Are Saying

Jared was most helpful at all stages especially with filling out the form during the cash back submission to Mitsubishi. I was very happy with Scott the electrician who returned the installation areas back to normal condition. Thanks Jared and Scott.

NOTTING HILL

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

Chris was exactly on time to do the quote, he was very knowledgeable about what would and would not work and the quote was fast and competitive. The installers were on time, courteous and professional. The installation was neat and they left the house tidy.

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.

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.

My ducted air conditioning system was not working it had been installed by another company. I rang to try and get someone to diagnose my problem,on the same day a serviceman turned up and it was fixed for $275.00. Well worth it. Neil from Beaconsfield

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.

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.

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. He was professional caring and overall a champion. Give the brother a few weeks paid time off and a raise and a promotion. 10/10 can't recommend enough

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. We love our new system: I would definitely definitely recommend Coldflow.

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.

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 ??

TRACEY S.

GARFIELD

February 2024

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.

LYNDHURST

June 2024

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.

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.

This is the second time we've used Coldflow, largely due to our positive experience the first time around.

Cleaned up and explained everything. Will recommend to others.

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.

Craig was great, explaining thoroughly & giving advice on appropriate systems to best suit our floor plan. Advised where best the systems should be installed. The young lads installing were absolutely marvelous! Very polite, very tidy & we can't fault their work. Thank you to all involved in making our purchase a hassle free transaction

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.

MOUNT WAVERLEY

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.

RESERVOIR

March 2022

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.)

BERWICK

September 2024

This my third dealing with Coldflow (3 different properties). Their response times are quick and they make the process extremely easy. The sales person is professional, responsive and easy to deal with. The installers took care, were polite and very easy to deal with.

ASCOT VALE

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.

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.

Daniel Hay, the person that measured up and provided the estimate was excellent. He was very professional and came across as very honest and trustworthy. The installer's were excellent on the day they just got on with the job and removed all the rubbish and vacuum up afterwards.
