Hartford Housing Stock
The median Hartford home dates to 1953, according to the Census ACS. That makes the typical house about 73 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. Owners live in 25.7% of occupied homes, roughly 13,000 households. With a median household income of $45,300 and a median home value of $217,200, 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 Capitol Planning Region from 2020 through 2025, so storm damage to outdoor units is rare here.
