In addition to cooling, ducted refrigerated air conditioning systems can also provide heating during colder months. These systems use a reverse cycle process, where the refrigerant is reversed to provide warm air through the same ducts that distribute cool air.

This makes ducted refrigerated air conditioning a versatile and efficient solution for year-round climate control.

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.

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.

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.)

This is the second time we've used Coldflow, largely due to our positive experience the first time around. Sales process was quick and easy - very clear and helpful with advice and suggestions about what we needed. Installers were lovely - really polite, efficient and thorough.

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!

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.
