Absolutely agree that's a classic sign of vent blockage! Overheating dryers are actually a serious fire risk that many homeowners don't realize. When lint accumulates in the ductwork, it not only reduces efficiency but creates dangerous conditions. What's concerning is how quickly this problem can escalate from just longer drying times to potential house fires. I need dryer vent maintenance regularly for this exact reason, and professional Dryer vent cleaning GTA services can thoroughly remove all that built-up debris. It's one of those maintenance tasks that seems minor but can prevent major disasters while also saving money on energy bills
