Ductless Mini-Split · Portland, OR

What ductless mini-split 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 jobs play out differently depending on which sector you live in.

Where we work in Portland

Five Portland sectors, one local crew.

  • Inner SE

    Sellwood-Moreland · Hawthorne · Richmond · Brooklyn

    Pre-1940 craftsman bungalows and four-squares on tight lots.

  • Inner NE

    Alberta · Sabin · Irvington · Beaumont

    Pre-1940 craftsman and bungalow stock, often with original ductwork.

  • SW

    Multnomah Village · Hillsdale · SW Hills

    Mid-century homes on hillsides — outdoor-unit placement gets interesting.

  • North

    St. Johns · Kenton · Portsmouth

    Older working-class housing on smaller lots, mix of bungalows and post-war.

  • Outer SE / East

    Lents · Powellhurst · Montavilla

    Newer post-war tract homes, more modern panels and duct systems.

Portland BDS permits, handled

We pull and submit every Portland mechanical permit.

Portland requires mechanical permits for HVAC work, issued by the Bureau of Development Services (BDS). We pull and submit on every install, schedule the BDS inspection, and you get the signed-off paperwork in your inbox.

Permitted, inspected, and signed off — that's how the manufacturer warranty stays valid and how a future buyer gets clean paperwork at closing. Skipping the permit saves nothing in the long run.

The basics

Mitsubishi Diamond Contractor: multi-zone heat & cool for additions, basements, and ductless homes.

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.
