Age, repair history, safety, efficiency, and comfort are compared together. A furnace over 15 to 20 years old with repeated major repairs, a damaged heat exchanger, or rising running costs is often a replacement candidate — but the comparison is made on your system, not on age alone.
By heat load, ductwork, insulation, and the layout of the home — not simply by copying the size of the old unit. An oversized or undersized furnace costs more to run and heats less evenly.
It depends on the system, ductwork, venting, and fuel or electrical supply. The scope and timing are explained before work begins, and the new system is started, tested, and shown to you before we leave.
