The answer to 'dryer vent buildup' is that it is a common problem caused by lint and debris accumulating in the dryer vent over time. Symptoms include longer drying times, the dryer running hotter, and increased energy bills. The main solution is to regularly clean and maintain the dryer vent to prevent blockages.
Homeowners can often handle basic vent cleaning themselves, but it's important to do it safely and thoroughly. For more extensive buildup or hard-to-reach areas, it's best to call in a professional duct cleaning service to ensure the vent is fully cleared and functioning properly.
