I've had a Mitsubishi Mr Slim MXZ-FE18NA heat pump for several years now as my main heating in Nova Scotia and in general I'm quite happy with it even though I live in an old farmhouse without the best insulation and sealing, but it does have one problem that is annoying and appears to be a programming mistake. With the vertical vent on auto and moving up and down from time to time as it blows heat into the room it will not infrequently blow what feels like cool air on people sitting below it. I've been told this air is still warmer than the temperature of the room so it's still heating the room, but it's cooler than the human body (anything between 70 and 98) and so feels decidedly cool and uncomfortable to anyone sitting below it. Of course, one can manually adjust the vent to the horizontal position but this is no solution because it would require adjusting the vent numerous times every hour depending on the temperature of the air being delivered. I think it should never blow air downward when it's below human body temperature. It should be possible to change this with a programming update, but I don't know if this is available. I've written them.
But this is one think to keep in mind if you're in the market for a heat pump. I don't know if the other Japanese makes have this problem.
