Report
Air Conditioning Highly Recommend First Class
I did a lot of research into this before l went with J J Engineering and had loads of companies round to quote for the work. And l must say from the start Gary's attention to detail was first class, he advised us what would work better for my house. There estimate was a complete breakdown of all materials as well as cost of the machinery. Unlike the other firms there estimates were just one or two lines. This made you feel like they knew what they was doing and you could trust their work. And no hidden costs. Also big thanks to Paul and Fred who were
