Warm air despite a set cool temperature is one of the most common calls our Acton, CA techs field, and it's rarely as simple as 'low on freon'. Ignoring warm air from the vents rarely makes the underlying issue cheaper to fix later.
This pattern shouldn't be ignored — some of the underlying causes carry genuine carbon monoxide risk. 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.
