This pattern shouldn't be ignored — some of the underlying causes carry genuine carbon monoxide risk. Our Marion, IL techs see this specific pattern often enough to diagnose it quickly rather than guess.
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. Our Marion, IL techs see this specific pattern often enough to diagnose it quickly rather than guess.
This is one of the most misdiagnosed HVAC complaints, since it's tempting to blame the thermostat instead of the actual airflow path. Our Marion, IL techs see this specific pattern often enough to diagnose it quickly rather than guess.
