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.

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 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.

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.

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.

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.
