Ducted Air Conditioning Installation for your home

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.

Their team of experts can guide you through the entire process, from initial consultation to final installation, ensuring that you get the best possible outcome.

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

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.

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.

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.
