A homeowner deciding whether a furnace repair can wait is really asking how much more cycling that unit has left in it. Homes in Washington run heat about ten months a year, from September through June. With so little of the year spent idle, the burner and the ignition system rarely get a long rest to recover from wear before being asked to fire again. That pattern favors problems in the parts that start the flame and carry heat across the exchanger, over failures that show up only after months of sitting unused. A furnace here earns its keep by running, not by waiting.
Before any new furnace or heat pump gets specified, a contractor has to open up what is already there. The ducts running through the house, the panel feeding it, the venting in place all get checked, not assumed, because what was installed at one point may not match what a new system expects. Half the homes in Washington were built in 1985 or earlier (2020-2024 ACS 5-year). That figure only means the checking has to happen, not what it will turn up. A newer service panel and a tight duct run are both possible in the same neighborhood, and only opening the walls and the equipment closet tells a contractor which one they are working with.
Does your Washington county get hit hard by severe weather?

Where a county lands on this list is a reason to look closer at the equipment sitting outside the house. Wind, hail and heavy rain all work against a condenser that has to keep running through them, and that is a factor in how the unit is sized and where it gets placed. Have a contractor check where your outdoor unit sits, how well it is anchored, and the condition of the unit itself.
