Champaign context
Champaign's housing stock spans more than 150 years since the city's 1855 founding, and a large share of the oldest homes had heating and cooling added well after original construction, long before ductwork and insulation standards were what they are today. That mix of construction eras across the Champaign-Urbana area is why HVAC retrofits and replacements are rarely one-size-fits-all.
