The safe bet: Regular servicing

Ducted heating manufacturers recommend that your system be serviced at least every two years, often just before or after winter when your system is being used the most. Proper maintenance will save you from high repair costs and the inconvenience of a breakdown when you need your heating the most.

Speak to Coldflow about a regular maintenance schedule so you can enjoy the peace of mind of a truly reliable system all year round.

Is your ducted heating system blowing out less air than usual?

Most ducted heating issues are overlooked as people think their system is just “getting old.” Often a simple fix has your system working as if it were new.

Speak to the experts at Coldflow today and accept nothing less than perfection from your ducted heating system. We can keep your home and business warm when it counts, no matter the issue!

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.

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!

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.

First of all, the communication was consistent and timely - I always knew where we were up to. On the day, the installation team were fast and efficient and you would not have known work had been done. Similarly, the electrician worked fast and clean. We are really happy with the process and with our new aircon units.

It was explained well about the ducted heating tests. Also the air grill needed replacement but the heating system was old and it may have been difficult to replace. It was fixed so it was not falling down all the time. The office rang to explain another option. However I was happy with the outcome. Thankyou

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.)
