Just had a new heat pump HVAC system installed by these guys and they were really fantastic. Arrived bang on time, when not early, super friendly, informative and considerate in the way they worked, seem to have done a great job. Put it this way, I'm a pretty intense introvert who hates the idea of strange people in my house and I found them more than bearable, I actually quite enjoyed their presence. So as far as the installation guys are concerned, I couldn't rate them higher. The system itself is also very impressive, so far at least. Effectively silent, great features I wasn't expecting, like infrared sensing to adjust for your location and the number of people in a room, and the piping actually looks pretty nice on the side of my house. Haven';t lived with it properly yet so can't say anything really about how it performs. But if I didn't write this review now I'd forget, so there you go. That's your lot.
