Prompt and good communication in letting customers know when they are about to arrive. They do and communicate what was done in service.

MARC P.

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
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.
LIZ P.
NOTTING HILL
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
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.

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.

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.

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 !
CHERYL D.
BENTLEIGH EAST
I just had my two units installed. Please pass on my thanks to Jared Wates, who provided the quote, and the team that installed the systems today. The installation team worked really hard, double-checked, if not triple-checked, and certainly made sure things were clean when they left. A very professional and courteous team.
STEPHEN R.
ROWVILLE
Jarred from Sales did an excellent job at explaining the whole process, helping me choose the correct model etc. Scott the installer was excellent, very clean, respectful, punctual and ensured the site was left in a clean state. Inside the house was also left spotless.
ROSS Y.
MOUNT ELIZA
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
Coldflow were great to deal with throughout the whole process. Communication was very good. Installers were on time, efficient and friendly. They moved furniture and picture on wall, put a sheet down over the carpet and left everything clean. Explained how to use the split system

MICHAEL F.
MENTONE
We'd highly recommend the team from Coldflow. Great communication, prompt and efficient installation and also great advice regarding the removal of our old gas wall heater. Not something we had considered but well worth it with the government rebate which we hadn't known about. Absolutely love our new Daikin unit too! Thanks coldflow.??
PETER M.
ASPENDALE GARDENS
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.

KATHLEEN K.
FERNTREE GULLY
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!
ANDREW R.
MULGRAVE
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.
Elizabeth A.
NARRE WARREN SOUTH
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
The whole process from selecting the Aircon, advised by Sales Rep Jared to the installation by Bailey and Anton was so efficient and smooth flowing. Installers were exceptionally courteous and helpful and professional. I couldn't be more pleased with the overall experience. Thank you very much!
Ranjit K.
FOREST HILL
All went well. I have had the heater on today and it is working as expected. The inside unit is very quiet and the outside section, which is just outside from where I sit, is unnoticeable. After having a listen outside I am convinced my neighbours will not hear any residual noise at all. The remote control is easy to use.
GILLIAN D.
MELTON SOUTH
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
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.
