What changes the number in Oregon
| Local cost indexAbove the national baseline | 1.14x national |
|---|---|
| Permit fee index | 1.15x national |
| Code basisStatewide code applies | Oregon Residential Specialty Code, based on the IRC |
| Owner-builder posture | Homeowner permits allowed on owner-occupied property |
| Largest markets | Portland, Salem, Eugene, Bend |
The formula
Cost = base unit cost x efficiency multiplier + venting + removal + permit
High-efficiency condensing furnaces (90%+ AFUE) need new PVC venting and a condensate drain, which is why the jump from 80% to 96% AFUE costs more than the equipment difference alone.
