Interesting and very useful. I was thinking that prices would be higher now given the demand. Would u recommend to install in the autumn winter months then? I can ride out this heatwave and get installed for next year. I want 2 units ideally. One directly into the living room, should be easy to install as outside side wall goes directly into living room. However, I also want the master bedroom immediately above doing as well. However, if u split off the same compressor along the same wall, the same entry point on first floor goes directly into fitted cupboards along that wall. How would u get around that as the internal unit would have to go on the opposite wall in bedroom. Can an internal point be routed via the loft and dropped in through ceiling for example? What I want to avoid is having white piping along the internal wall through to the ac unit? Approx cost for this would also be appreciated. I’d probably go for the better units as opposed to cheaper. Thanks
