Furnace tune-up in Marlborough: local context
Marlborough sits where Route 20 meets I-495, with a historic downtown, older neighborhoods of capes and colonials, and newer subdivisions and condo complexes built as the city grew along the highway.
Forced-air furnaces are common in the city's mid-century and newer homes, fueled by natural gas or oil, and many homes add central air through the same ductwork. Older homes may still have boilers, and more owners are adding cold-climate heat pumps.
