I installed the trunkings last mth & blowers/compressors early this mth during e renovation. Patrick will advise when I can call Ben to get his guys in. So far my hse still under renovation, but shld handover in 1-2 wks times. I've full-blasted all e blowers twice to chk for coolness, quietness & condensation. So far it cool my bedrms in under 1 hr & living rm in slightly 1 hr+. There is a powerful mode & quiet mode, as for e ioniser, sori, still trying to test this feature correctly, so cant comment at e moment. Note tat my hse is not fully furnished, so after all e furnishings, will try a couple more times.
The thing here is, it will depend where U placed your blowers as it will affect how your trunkings run, e shortest e better, e BTU for it, e workmanship of Ben's team using better materials & avoid condensation where possible & they provide 1 yr installation guarantee.
for e coordination part, to be fair to Patrick, since e aircon is source from yourself, hence U will be involved, but it not tat difficult, need a couple of calls to Ben to arrange for e installation. For e 1st site visit, it's best tat U, hb & Patrick are there with Ben's installer to discuss on how to run e trunkings, pass them 1 key & Patrick will advise when U can call them in.
