Warm air despite a set cool temperature is one of the most common calls our Twin Lakes, WI techs field, and it's rarely as simple as 'low on freon'. Our Twin Lakes, WI techs see this specific pattern often enough to diagnose it quickly rather than guess.
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.
