The repair-vs-replace call is where most Portland homeowners get burned by contractors who push whichever answer is more profitable. The honest math: if a furnace is under 12 years old and the repair is under roughly 30% of replacement cost, repair it. Past 15-18 years, especially on an 80% AFUE unit, a failed heat exchanger or cracked igniter board is usually the signal to replace rather than keep feeding parts into a furnace that's already losing 20 cents of every gas dollar to inefficiency. We'll show the actual repair estimate next to the replacement estimate on paper before recommending either one — that comparison, not a sales pitch, is what should decide it.
Portland's older housing stock changes the job in ways a generic install quote doesn't account for. **Craftsman and bungalow homes** in Alberta Arts District, Irvington, and Laurelhurst were often built in the 1900s-1940s with gravity or early forced-air furnaces shoehorned into low-clearance basements or crawlspaces — pulling the old unit out sometimes means temporarily disconnecting knob-and-tube-era wiring runs or working around original brick chimneys no longer in use. Sellwood-Moreland and Woodstock have similar vintage housing, where the ductwork itself, not just the furnace, needs inspection since decades-old sheet metal often leaks 20-30% of conditioned air before it reaches the vents.
A meaningful number of Portland homes — especially older bungalows in St. Johns, Montavilla, and Lents — never had central ductwork installed at all and rely on wall heaters or baseboard electric. For those houses, a **ductless heat pump system** is often the better fit than forcing in a furnace and duct network from scratch: it heats and cools (useful during summer heat spikes and wildfire-smoke season when windows have to stay shut), and Energy Trust of Oregon incentives can offset a meaningful chunk of the install cost. We walk through that comparison — furnace-plus-ducts versus ductless conversion — on the same visit, with real numbers for your specific house, not a generic brochure.
Every installation gets a **written quote before work begins**, a permit pulled where required, and a final walkthrough covering the new thermostat and warranty paperwork. There's no upsell script and no pressure to sign same-day — the quote holds while you decide.

Furnace Installation & Replacement — questions, answered
How long does a furnace installation take in a Portland home?
A straight furnace swap in Portland — same fuel type, same location, existing ductwork usable — is typically finished in one working day. Homes needing duct repair or a switch to ductless heat pumps usually take one to three days.
Should I repair or replace my furnace in Portland?
If a Portland furnace is under 12 years old and the repair costs less than about 30% of a full replacement, repairing it is usually the better value. Past 15-18 years, especially with a cracked heat exchanger, replacement is typically the more cost-effective choice.
Can older Portland homes without ductwork get central heat installed?
Yes — many bungalows in St. Johns, Montavilla, and Lents never had ducts installed, and a ductless heat pump system is often a better fit than adding ductwork from scratch, since it also provides cooling during Portland's summer heat spikes.
