Save the scary noises for Halloween.
A new bang, rattle, squeal, grind or repeated click from heating or cooling equipment is useful information—not a soundtrack. From a safe distance, note when it starts, whether the system is heating or cooling, and how long it lasts. Don’t remove panels or reach inside. If the noise persists or comfort changes, arrange qualified service.
