How often should you clean your dryer vent? To keep your dryer working at peak efficiency, in most cases, once every one or two years is fine, or every 365 loads. Some factors that will cause the pipes to clog up faster are pet fur, new clothing, sheets, or towels. We find that homes with multiple shedding pets will need to have the dryer vent cleaned twice a year or more, especially the ones with long-haired dogs or cats. We know all about how to get the lint out, so give us a call today!
