Community Tips
Dust buildup on registers reduces airflow efficiency by up to 30%, so cleaning them quarterly rather than annually can lower energy bills noticeably and prevent the system from overworking. Start by vacuuming with a brush attachment, then wipe register faces with a damp cloth to capture fine dust that accumulation traps.
A Ryobi One+ 18V Cordless Handheld Vacuum ($60-90) with brush attachment outperforms corded models for this task since it reaches high wall vents and ceiling returns without dragging a cord through furniture. The compact nozzle fits tight spaces between vent slats where dust accumulates fastest.
Never use compressed air to clean registers, as it forces dust deeper into the ductwork and can lodge particles against elbows and transitions where they compact into blockages. Compressed air also risks pushing debris into the furnace blower wheel, potentially causing costly damage or triggering safety shutoffs. ---
