How ductless mini-split works
What a ductless mini-split job looks like in Milwaukie.
Ductless mini-splits add heating and cooling to spaces a central system can't reach: additions, finished basements, garages, ADUs, and homes without ductwork. A single outdoor unit can run up to 8 indoor heads, each independently controlled.
We're Mitsubishi Diamond Contractors, a designation Mitsubishi limits to a small number of installers per market. Diamond installs come with a 12-year manufacturer parts and compressor warranty (twice the standard 7-year).
Hyper-Heat technology runs efficiently down to -13°F, well below anything this region sees. Indoor heads run as low as 19dB, quieter than a library, so bedrooms and home offices stay quiet.
