Warm air despite a set cool temperature is one of the most common calls our Stony Brook, NY 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.
A system working harder than it should to hit the same setpoint is a system with a developing problem, even if it hasn't fully failed yet. Ignoring rising utility bills with no usage change rarely makes the underlying issue cheaper to fix later.
A grinding or squealing sound usually points to a motor bearing wearing out; a banging sound during startup often means a loose or broken internal component. Ignoring strange noises: grinding, squealing, banging rarely makes the underlying issue cheaper to fix later.
