Portland prices a heat pump against the friendliest operating climate in this guide's family: wet, mild winters with design nights in the mid-twenties, dry summers that used to be optional to cool and no longer are, and an electric grid whose rates make the heat pump's arithmetic work all year. The machine is close to purpose-built for this place, which is why the metro's real pricing questions are not about the climate at all. They are about the house: the 1920s Irvington foursquare with an oil furnace and no ducts upstairs, the Alberta bungalow on zonal electric heat, the Beaverton ranch with a gas furnace and a summer that finally demands cooling. This guide lays out the 2026 bands, then walks the levers that move a quote inside them, with the Energy Trust rebate layer waiting at the end.
The Bands in One Table
| Project | 2026 band | Typical Portland case |
|---|---|---|
| Single-zone ductless | $3,500 to $7,000 | One room, an ADU, a zonal-heat bedroom |
| Multi-zone ductless | $8,000 to $16,500 | Older house without usable ducts |
| Ducted changeout | $7,000 to $14,000 | Swapping a gas or oil furnace system |
| Whole-home conversion | $13,000 to $25,000 | Full system, often with duct work |
| Dual fuel | $10,500 to $20,000 | Heat pump plus retained gas furnace |
| Panel or electrical work | $1,500 to $4,000 | Older service, new circuits |
Why the Bands Run Wide
Two houses a mile apart land at opposite ends of the same band honestly. A changeout in a 1990s Hillsboro two-story with sound ducts and a modern panel sits near the bottom; the same nominal project in a Ladd's Addition foursquare with a basement oil furnace, knob-era wiring, and ducts that stop at the first floor climbs toward the top for reasons a good contractor itemizes rather than buries. The band is not the price; the site visit produces the price, and the load calculation produces the size, per our contractor guide. A quote written without both is a guess wearing a number.
The Ductless Path, Which This City Practically Invented
Portland's older stock made the metro one of the country's natural ductless markets: bungalows and foursquares heated by zonal electric, wall heaters, or radiators, with no duct system to inherit. Single-zone units at $3,500 to $7,000 solve one room, an ADU, or the classic upstairs-bedroom-in-August problem. Multi-zone layouts at $8,000 to $16,500 carry whole smaller homes, with price driven by head count, line-set routing, and where the outdoor unit can sit on a small city lot. The Energy Trust standard path pays about $800 on qualifying ductless equipment, per our rebates guide, and the income-qualified path pays much more.
The Changeout, and What the Old Fuel Changes
The $7,000 to $14,000 ducted band covers swapping a furnace-based system for a heat pump on existing ducts, and the old fuel shapes the scope. A gas furnace swap is the cleanest case. An oil furnace swap, still common under older Portland houses, adds the tank question: decommissioning or removal belongs in the quote as a named line, not a surprise, and the fuel arithmetic that motivates the whole project lives in our fuel comparison. Electric furnace and zonal-heat conversions are the simplest electrically and often the strongest financially, because the operating savings start from resistance-heat bills.
Ducts in the Basement and the Crawlspace
Metro ductwork mostly runs through basements and crawlspaces rather than baking attics, which is kinder to the ducts and different in its failure modes: crawlspace runs sag, disconnect, and drink moisture in the wet season. The credible contractor measures static pressure before sizing anything, walks the crawlspace rather than assuming it, and prices sealing and insulation as first-class options. In houses where the ducts stop at the first floor, the honest answer is often a hybrid: ducted downstairs, a ductless head upstairs, priced as one system.
Whole-Home, Dual Fuel, and the Panel
A whole-home conversion runs $13,000 to $25,000 and buys the house redesigned around one efficient machine. Dual fuel, a heat pump over a retained NW Natural furnace, prices at $10,500 to $20,000; in a climate with mid-twenties design nights it is rarely an engineering necessity, but it is a legitimate configuration for households that want the furnace as a backstop. Older stock often carries older service, and panel work runs $1,500 to $4,000. The honest bidder opens the panel at the site visit and prices what they find as a named line rather than a post-signing change order. One question sorts them: what does my panel need, and is it in this number?
The Cooling Line That Did Not Used to Exist
For decades, the metro's houses skipped air conditioning, and the housing stock shows it. The heat pump ends that gap as a side effect: the same machine that heats the wet season cools the dry one, and for most of the older stock this is the first real cooling the house has ever had. That changes the value math in a way sticker-price comparison misses: a furnace replacement buys heat; a heat pump at similar net cost buys heat and the cooling the last few summers have made non-negotiable, per our cold-weather guide.
What the Rebates Move
Against these bands, the Energy Trust layer is a meaningful trim: about $800 ductless and $1,000 ducted on the standard path, $200 to $2,000 by tier in the electric territories, and $1,800 to $3,000 through Savings Within Reach for income-qualified households, which on a $9,000 multi-zone project is a fifth to a third of the invoice. The federal credits ended December 31, 2025 and belong in no 2026 net-price math. Check the income-qualified path before pricing anything; it is the largest single line most eligible households never claim.
Reading Three Quotes
Run three bidders against this page and the spread tells its own story. The fast, low, paperless bid priced a nameplate copy, not your house, and probably never walked the crawlspace. The high, thorough bid should justify its scope line by line, and a good contractor does. The quote worth signing usually sits where the documents are: load calculation attached, duct findings written down, panel and tank named where they apply, and the Energy Trust line stated with the tier and the filing path. Price matters between bids that did the work; between bids that did not, it is noise.
The Short Version
Ductless runs $3,500 to $7,000 for one zone and $8,000 to $16,500 for several; a ducted changeout runs $7,000 to $14,000; whole-home conversions reach $25,000; dual fuel sits between; panel work adds $1,500 to $4,000, and oil-tank decommissioning belongs in writing where it applies. Energy Trust trims $800 to $1,000 standard, up to $2,000 by tier, and $1,800 to $3,000 income-qualified. The number that decides fifteen years of comfort is the tonnage from a real load calculation, sized for the mid-twenties design night and the summers that now count.
