Daniel was great to deal with, thorough, answered all our questions and communicated well the whole way through. The installation team that come out were fantastic. Double checked anything they needed to, polite, personable and respectful of our home and that my partner was working from home while they were here.

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.

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.

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.

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. 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.

I just had my two units installed. Please pass on my thanks to Jared Wates, who provided the quote, and the team that installed the systems today. The installation team worked really hard, double-checked, if not triple-checked, and certainly made sure things were clean when they left. A very professional and courteous team.

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.

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. My wife and I are very happy with the installation.

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.

Prompt and good communication in letting customers know when they are about to arrive. They do and communicate what was done in service. Any questions are answered and I like the professionalism of turning up in a company named work vehicle and uniform. Also the payment method is trusted with a receipt on the email

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.

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.

Team did a great job, install team had to vary the installation location of parts, access etc, vs. communicated during the sales process. This is fine, just a note that worth getting feedback from your install team to your sales team to help future customer comms. The team kept the site clean and took away all rubbish which was great
