Hillsboro Housing Stock
The median Hillsboro home dates to 1997, according to the Census ACS. That makes the typical house about 29 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 21,000 households here own their home, 50.6% of the occupied total. Homes here have a median value of $483,400 and households a median income of $103,207. Those two numbers drive the labor adjustment in our estimate.
Washington County had 1 hail day and 1 day with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.
