Manual J Load Calculations in Oregon
Permit-ready Manual J, D & S reports for Oregon HVAC contractors — from the marine Willamette Valley to high-desert Central Oregon. We serve Portland, Salem, Eugene, Bend, Medford, and contractors across the state.
Manual J for Oregon's Climate
Oregon spans Climate Zones 4–5 — but it's really two climates. The marine-influenced Willamette Valley runs mild and wet with heating-dominant loads, while Central Oregon's high desert brings colder winters and big day-night swings.

Willamette Valley & Coast
Portland, Salem, and Eugene sit in a mild, damp marine climate. Heating leads and cooling is modest, so sizing has to reflect that balance rather than a generic split.
Central Oregon
Bend and the high desert see colder winters, lower humidity, and large day-to-night temperature swings. We calculate loads for those real conditions, not a statewide average.
Rogue & Umpqua Valleys
Medford and southern Oregon run warmer and drier in summer than the coast, raising cooling demand. We account carefully for the inland valleys.
