Most Air Duct Cleaning emergencies in Williston, SC gave some warning first, even if it was easy to dismiss at the time.
A system that runs but never actually cools usually means a refrigerant charge issue, a failing capacitor, or restricted airflow — not something a thermostat adjustment will fix. 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.
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.
