What Our Customers Are Saying
  • Excellent service & workmanship

    This is my second system that Coldflow have installed and I'm very happy with the result.
    2 head air conditioning system installation was quick and tidy. Even though the cassettes are more complicated and involved to install. All the guys cleaned up after themselves and took all the rubbish away. Excellent service and workmanship, even when it rained and then heat (it's Melbourne).
    System work a treat, just waiting for the heatwave to arrive. Great work by the team.

  • Again, very happy with the service

    I was extremely happy with the service provided by Coldflow.
    I had a ducted cooling system installed. The team turned up on time and completed the job the same day. The guys were courteous and completed the job with a minimum of fuss and disruption. The workmanship was excellent and all ducts were located as per our agreement. They placed drop sheets wherever required and cleaned up after completion. Again was very happy with the service provided by all the crew.

  • Recommended already to friends

    Replaced gas ducted unit. Installation was the perfect I have ever seen and the installers cleanup and did more than they were suppose to do. Customer service focused and really good company to work with. Have also got my cooling installed from them last year, so recommended already to friends and to anyone needing Heating and Cooling

  • I highly recommend Coldflow and would use them again

    From my first conversation with a consultant, I felt confident that Coldflow had the experience and knowledge I was looking for. I was thrilled with the level of customer service I received and follow up from them. The installers were professional and helpful and on time. I am very happy with the evaporative cooling unit we chose, thanks to the assistance and guidance of our consultant. I highly recommend Coldflow and would use them again.
