Boiler Replacement Cost in Eugene, Oregon
Our 2026 estimate for boiler replacement in Eugene, OR is $6,100 to $13,900. That puts Eugene 11% above the national average, mainly because of the bigger heating equipment this climate calls for.
Eugene Weather and HVAC Load
In a normal year, Eugene racks up 4,615 heating and 292 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Eugene put in far more hours than the air conditioner. Count on roughly 52 nights below 32°F and 18 afternoons past 90°F in a typical year. Snowfall averages about 3 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 4,615 |
|---|---|
| Cooling degree days / year | 292 |
| Nights at or below 32°F | 52 |
| Days above 90°F | 18 |
| Average low / high | 41.9°F / 64.3°F |
Eugene Housing Stock
Census figures put the median build year in Eugene at 1979, so a typical house here has about 47 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Owners live in 47.6% of occupied homes, roughly 36,000 households. Homes here have a median value of $435,400 and households a median income of $63,836. Those two numbers drive the labor adjustment in our estimate.
Lane County had 2 hail days and 1 day with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.25 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost.

- The boiler is 20 to 30 years old or more
- The pilot or ignition keeps failing
- Leaks, rust, or pressure that keeps dropping
What Moves the Price
- Condensing or non-condensing boiler
- Fuel type: gas, oil or propane
- A combi boiler that also makes your hot water
- Pumps, zone valves and the piping around the boiler
- A new chimney liner or venting
We raised the national figures about 11% for Eugene using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover

Oregon Permits, Efficiency Rules and Rebates
Oregon falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Eugene generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Oregon license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
