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.

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
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
