What ductless mini-split installation actually looks like in Portland.
Portland sits in IECC Climate Zone 4 Marine — mild winters that rarely drop below 20°F, prolonged damp shoulder seasons that extend heating demand, and occasional summer heat domes (the 2021 event hit 116°F) that have made AC and heat pump installs the new baseline.
Pre-1940 Portland homes commonly run 60- or 100-amp electrical panels and balloon-framed walls — both shape how a heat pump retrofit, return-air duct routing, or AC install actually gets done. Tight crawlspaces and original cast-iron drain lines also factor in.
We work across all five Portland sectors: inner SE, inner NE, SW, North, and the Outer SE / East corridor. Each one has its own housing-stock quirks, and ductless mini-split installation jobs play out differently depending on which sector you live in.

How ductless mini-split installation works
What a ductless mini-split installation job looks like in Portland.
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.
