Do home buyers have a strong preference for the highest efficiency furnace possible?I need to replace the furnace before selling my SF Bay area home. An 80% efficient furnace is simpler than a 96% efficient one since it doesn't require a new separate exhaust vent and a condensation line. The usage history doesn't justify the added cost even though it's not that much (~$1500).
