I had air conditioning (with a water cooled condenser so no outdoor box) installed in my high rise flat. Mark and the team did a phenomenal job. Installation went by quickly in 1 day and with extremely minimal patch up work required. I wish I had done the installation sooner! The units are very high quality Panasonic ones, wifi connected and compatible with Google Home, Alexa, etc. so I can set the temperature as I am heading home from work. I have had the units for a year bow. I can’t recommend them enough!
