Rockford context
Rockford's housing stock spans a Victorian and bungalow-era core in neighborhoods like Haight Village through postwar ranch construction and newer subdivisions ringing the city, so duct layouts and equipment age vary widely block to block. Long, humid summers push cooling loads hard while winters average lows near 14°F with heavy January snow, making properly sized equipment essential in either direction.
