Warm air despite a set cool temperature is one of the most common calls our Liguori, MO 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.
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.
