Refrigerated cooling problems can make your home very uncomfortable and cause your business to essentially shut down. When these systems fail, the internal temperatures rise, as does the humidity, moisture, and risk of mould growth.

The importance of regular and quality repair services

Your cooling system involves a lot of intricate parts and is often under continuous heavy use, especially during summer. It makes sense that over time, these parts wear and tear.

If left for long periods, small issues can get much worse and far more expensive. Along with more intense repair work, these issues may jeopardise the functional capacity of your system. A regular system repair service provides the following benefits:

What Our Customers Are Saying

Overall very satisfied. Quick to come out to quote, gave various alternatives and recommendations. Installers were very efficient installing four units in a few hours without leaving a mess and units are positioned nicely. Also much more competitive offer than another couple of quotes I received.

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.

This was an incredibly easy process for us from start to finish. Daniel was wonderful at determining the best fit for our house and life and made the selection process so easy. The team on the day were quick and did a great job. We can't believe it didn't even take a full day. We are so happy with everything!

The installers were exceptionally good. Understood the fragility of my ceiling and dealt with my threatening neighbour when they climbed on the roof on my side. The technician also gave me advice on how to keep the filters healthy and what setting to use. Thanks Coldflow.

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.

Very glad and relieved I chose Coldflow. Your installer Murray arrived at 7am Monday 21st, was quickly to work with a minimum of fuss. Old Brivis unit and new Braermar unit out and in through the roof. All over by 9am. He showed us how to use the Braemar control unit before leaving. Great job.

Notified half hour before arrival, arrived on time, service completed without fuss, used protector to safeguard flooring and minimise mess, showed photos of issue and how it was rectified, explained report and length of warranty on 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!

The whole installation and mains connection went seamlessly, with only a very small 'mains disconnect' period, which was great as my son is currently WFH and had a very small unavailability time with work. Very happy with the whole process, from quote to installation.

The young guy was very polite, knew what he had to do , and told me what he HAD done. BTW , I was the one that organized many of Braemar heaters to be installed here in my village. ( Waterford Valley Lakes) I would have thought that you would have organized ALL the other ones to be serviced at the same time as they are the same age.
