Great system with Wi-Fi adapter

We had the unit installed last week. Very quiet and economical to run. We also wanted it to connect to Google home so got the Wi-Fi adapter. Early days, but everything works great.

Can't fault it

I inherited this when I moved in recently – it is quiet with only the noise of air moving, rather than machinery, and one unit does the whole bottom floor, up the stairs and the landing upstairs (but not the bedrooms), so I am happy with the performance. The remote (wall mounted) has a lot of settings on it, but easy enough to get the basic settings you need done – I need to look at the manual to do automatic timings etc. all the fancy stuff.

Excellent quick cooling and heating, great economy and quiet functions, look great. We absolutely love our MHI air conditioner! This size unit heats and cools our living area in an instant. Put it on the highest airflow in summer and it cools the house I also love how quiet it is, does not disturb my sleeping baby! Sometimes I have to double check it’s working because it’s so quiet!
