Clogged dryer vents restrict the flow of hot, moist air, forcing the appliance to work harder and run longer to dry clothes completely. This inefficiency leads to increased use of both electricity and gas, depending on the dryer type, and can cause energy bills to rise noticeably. Over time, the added strain can also shorten the lifespan of the appliance and increase the likelihood of breakdowns. Keeping vents clear of lint and debris allows the dryer to operate at peak efficiency, reducing energy consumption and saving money while lowering the risk of overheating or fire hazards.
