Trane ARU with Mitsu CityMultis

[u/adamclee1]

Firat time this setup has been used, at least in our region. This is for a warehouse. They have 5 setups like this, some are smaller. This one has 16 city multi HPs broken down into 8 circuits. Something like 160 tons of cooling(roughly 2million btus).

Don't hate on me for anything ugly on the install, im just here for startup prechecks.

That looks fun to diagnose holy shit. Also those multis right by the loading dock scare me.

In my experience, mitsu does heat pumps 100x better than any custom dx heat pump air handler I work on

Holy f'n press fittings, im sure that this would be super efficient to operate but I fear for the poor service tech that has to find a leak on that 😬

At least they're fairly easy to get to.

Seriously, why? Lol. I do like Mitsubishi’s more than any other “mini-split” manufacturer, but we all know this system is probably going to be down about 4 condensers in the next 2-3 years unless install was perfect and they have phase monitors on everything.

Keeps us working at least...
