3 Head Mitsubishi Ductless Install Review

My business partner Eric Rauser, AIA designed this amazing Perfect Wall house and it’s the first house I’ve built that’s completely free of duct work!  (See this older blog post for more on Perfect Wall) The house is incredibly efficient with a blanket of exterior rigid foam on all sides (and the roof), a radiant barrier metal skin, and a super tight envelope… it’s really a perfect house to go ductless.

Here's the porch brackets with insulation going behind them.

All reading for siding. Rainscreen 1x4 battens installed over foam.

Now that you’ve seen some pictures of the house under construction, here’s the completed house.  This is a rather small 2 bed, 2 bath 1700 sf house but this Mitsubishi 3 head system has worked perfectly in the past 2 years since we’ve finished this home.

Head is above the louver door into the pantry/laundry room.
Study which is opposite the Living/Kitchen has one head too. This room doubles as a guest bedroom.

All three heads are tied to one outdoor unit.  Each head has it’s own controller, yet with the Mitsubishi VRF compressor they all can draw what they need from the single outside unit to cool/heat that particular space.  (remember they all need to heat or cool at the same time, you can’t heat up and cool downstairs)  Pretty terrific if you ask me!  If you are considering one of these units, I would highly recommend them.  Build a tightly sealed, well insulated box, and forgo the ductwork!  More info at http://www.mehvac.com/
