Thanks! I also saw my first one while visiting my son in Japan when
he was a foreign exchange student there. They seem to work great,

Are you planning to self install?

If so, please do post a report.

No Malcolm, I will be using a local HVAC contractor. I did install a
prior 3 ton Freon system here years ago, and had the luxury of a
pre-charged line set, diaphragm-piercing Shrader valves, and a stronger
back than I have now. Buying a jug of refrigerant was a piece of cake.

I am very comfortable with paying a professional to handle the R-410
and do all the work involved here. I am also likely to be going with a
zoned system with 2 or more line sets going from wall units to a single
outdoor compressor. I would imagine that weighing the refrigerant and
knowing how these systems work will be vastly superior by someone who
does this for a living as compared to what I would likely accomplish as
a first-time installer.

There are also warranty considerations, and I am not looking to replace
any of this at my own expense for a long time, if possible.
Mitsubishi-certified dealers are my best choice in this regard as well.
