The 2 servicemen were absolutely 1st class. Extremely knowledgeable, clean and efficient. Very importantly they were also extremely considerate of my house and how they conducted themselves!

BRIGHTON EAST
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!

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.

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.
ANT B.
KILSYTH
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

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 !

The whole process was smooth from beginning to end. (Brian was Sales Rep). Good communication was provided via phone or txt msgs. The installer (Matt) was punctual, professional, polite, friendly, and a hard worker on a very hot day! A/c unit is effective, quiet and a slimline design. Thank You!
JENNY T.
CLYDE NORTH
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.
AAFKO S.
HEATHMONT
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.

The staff who attended to me was very good, courteous, communicated well and did everything possible to identify the problem and he did identify the problem. He also clearly explained the possible options for resolving the problem. I was very happy with his conduct.

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

This was an incredibly easy process for us from start to finish. Daniel was wonderful at determining the best fit for our house and life and made the selection process so easy. The team on the day were quick and did a great job. We can't believe it didn't even take a full day. We are so happy with everything!
Tess F.
COBURG
The two technicians were well mannered, presented well as representative of your company and did a good job explaining what they had done in terms of the service of our gas heater. They were polite, arrived when they said they would which is important given we work form home and have work commitments. Great ambassadors for your company.
MARIANNE S.
BALWYN
Very happy with the whole process. All were knowledgeable and professional and turned up on time. They also worked through some pretty wet cold and windy weather but just got on with the job. Everything was explained and we were consulted if there were changes needed The system is working well and we are very happy with it
DIANNE L.
KEYSBOROUGH
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.
Madeleine L.
KENSINGTON
Rang for a service on the existing gas ducted heating system to find the system had died. A quote for a new system was provided on the day and installed the next day. The installation team were excellent, providing great advice and support during the installation. Sincere thank you to all.
TINA M.
TEMPLESTOWE
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!!
MARC P.

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.

Nick came and installed my parents heating and evaporative unit and was absolutely amazing to deal with. He was professional, polite and most of all happy to answer all our questions. Thank you Nick. Thank you to Tom the sales rep who originally came to see us too.
ANGELA M.

After 4 weeks of research, quotes & cold to replace split system I am very happy with Coldflow from Daniel coming to give quote, efficient installation by pleasant men & communication on phone. Cosy now with my bigger heating system as advised. Thank you. Would recommend you from my experience.
TRISH A.
BALWYN
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.
ANNELISE B.
ROWVILLE
Luckily service personnel came early in the 4 hr window which suited me. Both were very polite and carried out the servicing plus they were able to respond to a couple of questions I had about this aircon unit ( I've recently moved in to new flat) Very satisfied Thank you Julie
JULIE B.
SAINT KILDA WEST
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.
PETER H.
MITCHAM
Relatively minor problem. Serge took due diligence and checked whole unit. May need a new stop valve in future. He explained how how well our 19yo unit is functioning and gave us thoughts on future possibilities. Obviously a very experienced technician and a real gentleman.
ROD P.
KILSYTH SOUTH
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
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.
LINDA F.
CLYDE
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.
JULIE D.
HAWTHORN
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.

We were very happy with the whole process, from the Sales Consultant Liam, to the installers Josh, Anton, Bailey and Casper. They were all excellent workers from the moment they arrived to when they left. They were on time, polite and cleaned up all of their mess. Would highly recommend.
DEBBY F.

I was especially happy with the happy with the airconditioner installed in my bedroom.I can highly recommend tle 2 young men who installed it. They were very polite, the airconditioner is well fitted, it works well and when cleaned up after their work. The office workers were helpful responding to calls and answering my questions.
ALMA K.
SOUTH MORANG
I received a call about 20 minutes before the team arrived at my house. They were extremely helpful and friendly. I was able to pay for the job on the spot, or alternatively, the office could send me an invoice. I appreciated the flexibility of the payment methods.
SUE W.
HIGHETT
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.
LAUREN C.
RINGWOOD NORTH
On time, informative quote from pleasant sales person. Quick, clean install from pleasant on time installer. Installation even brought forward, quote on Wednesday, instal on Friday! So far great service just got to see how unit performs in hot weather.

Debra K.
ASCOT VALE
Every step of the process was first class and professional. You did what you said you were going to do, on the days that you promised and the installation was like swiss clockwork. Best service experience I have had in the last 5 years. Special shout out to Shanon who organised superbly from day one.
DARYL K.

Amazing turnaround and communication! We had a sales person booked in 3 days after we made the online enquiry. Quote was provided on the spot. All questions answered promptly. Installation one week later. All completed in one day. Sales and installations staff were all super friendly, approachable and helpful. Could not fault the team or service!
MEGAN T.

Double checked anything they needed to, polite, personable and respectful of our home and that my partner was working from home while they were here.

Ranjit K.
FOREST HILL
Team did a great job, install team had to vary the installation location of parts, access etc, vs. communicated during the sales process. This is fine, just a note that worth getting feedback from your install team to your sales team to help future customer comms. The team kept the site clean and took away all rubbish which was great
CHARLIE H.
FAIRFIELD
Our tech Ray did an outstanding job fixing our ducted heating system. It is very obvious that his experience makes him a valuable asset to Coldflow! Thanks for explaining every step of the repair so clearly & for your relaxed & friendly manner! Will 100% rebook a service as it is required down the track! Thanks again!
SEAN M.
DINGLEY VILLAGE
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.
GREG C.
MULGRAVE
The whole process was very smooth end to end and we are very happy with the result. Everyone we dealt with was very professional and got back to answer our queries right away. We have already recommended Coldflow to 2 of our friends who are looking to have split systems installed.
KATHY H.

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.
