Very professional service. Mark and Ian responded and organised my installation quickly. The team doing the work on the day were similar. I let them into my flat, we discussed the details of the installation and then I left for the day. When I came back, everything was installed, boxes were taken away and the flat was cleaned (they bring their own cleaning equipment). It has worked excellently since: it is extremely quick to cool the rooms down, and the cost is not bad. Would highly recommend them.
