• The typical home in Clinton Township was built in 1980.
• When replacing a furnace or air conditioner in a home built around 1980, ask for a load calculation (ACCA Manual J) instead of matching the old unit's size: insulation, windows and duct condition change over the decades, and a correctly sized system runs more efficiently.
• Clinton Township is heating-dominated, so heating efficiency matters most when you replace a system: AFUE for furnaces, HSPF2 for heat pumps. With winter nights averaging below 20°F, ask for a heat pump rated for cold climates if you go electric.
