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. Ignoring furnace won't ignite or keeps shutting off rarely makes the underlying issue cheaper to fix later.

One room that's always too warm or too cold while the rest of the house is fine usually traces to a duct, damper, or airflow issue rather than the system itself. Ignoring uneven temperatures room to room rarely makes the underlying issue cheaper to fix later.
