A furnace that clicks but never lights, or one that lights and shuts off within seconds, usually points to a failing ignitor, a fouled flame sensor, or a safety switch doing exactly its job. Our Thayer, IL techs see this specific pattern often enough to diagnose it quickly rather than guess.
A system working harder than it should to hit the same setpoint is a system with a developing problem, even if it hasn't fully failed yet. Ignoring rising utility bills with no usage change rarely makes the underlying issue cheaper to fix later.
