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.

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 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.
