St. Paul Housing Stock
Census figures put the median build year in St. Paul at 1952, so a typical house here has about 74 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 65,000 households here own their home, 53.2% of the occupied total. Homes here have a median value of $280,300 and households a median income of $73,055. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 9 hail days and 12 days with damaging thunderstorm winds in Ramsey County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.
