Hi. I noticed one day that my dryer was overheating and taking longer to dry. It turned out that the vent was almost completely clogged with lint! Not only does this reduce efficiency, but it can also cause a fire. I called the experts from dryer vent cleaning services Newmarket, they quickly cleaned everything out, and now the dryer works like new. I recommend cleaning it at least once a year, especially if you use the dryer regularly!
