Keeping floor registers in good condition boosts airflow and extends their life. In spring, wipe away dust, pet hair, and allergens with gentle cleaning. For summer, be sure vents stay clear of rugs and furniture, wash with mild soap, and adjust dampers for efficient cooling. In fall, tighten any loose registers, schedule a deeper clean, and look for signs of rust. During winter, prevent condensation, seal gaps, and balance heat across rooms. With steady seasonal care, registers stay effective, durable, and visually appealing year-round.
