Catching a problem early, before it becomes a total breakdown, almost always means a shorter repair and a smaller bill.
A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.
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.
Dirty coils, duct leaks, and failing components all show up on the utility bill before they show up as a total breakdown. Ignoring rising utility bills with no usage change rarely makes the underlying issue cheaper to fix later.

This is one of the most misdiagnosed HVAC complaints, since it's tempting to blame the thermostat instead of the actual airflow path. Ignoring uneven temperatures room to room rarely makes the underlying issue cheaper to fix later.
