New Haven Housing Stock
Half the homes in New Haven were built before 1952 (Census ACS median), so the typical house is about 74 years old. 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 15,000 households here own their home, 28.4% of the occupied total. With a median household income of $53,771 and a median home value of $249,000, local labor rates come out below the national middle in our model.
NOAA's Storm Events Database shows no hail or damaging-wind days for South Central Connecticut Planning Region from 2020 through 2025, so storm damage to outdoor units is rare here.
