Older homes often have basements with boilers or older furnaces, while newer subdivisions have gas furnaces and central AC. Cathedral Area and Upper Bluff homes date from the late 1800s and early 1900s, many built of local limestone, with radiators and limited duct space. Newer west-side and Plainfield-area subdivisions were mostly built in the 1990s and 2000s with gas furnaces, central air and basements. For AC Replacement & Installation, that means the contractor should start with load calculation and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: older homes. Boilers and converted ducts need regular service.
