Furnace sizing should account for more than square footage. Insulation levels, windows, ceiling height, ductwork, air leakage, and the home’s layout all affect heating needs. This is especially important in Bellevue’s mix of older ranch and split-level homes, remodeled properties, and newer construction. An oversized furnace can short cycle and create temperature swings, while an undersized system may struggle during Nebraska cold snaps. Apollo Heating and AC can evaluate these factors and recommend a properly sized furnace installation for your home.
