This winter has been one of the coldest on record. Due to the cold snap, many homeowners have looked for new ways to improve heating efficiency. One great way method that is often overlooked is to keep dryer heat inside. Most homes expel the heat produced from drying clothes, which is a must for gas dryers. They produce dangerous carbon monoxide that must be vented. However, for electric dryers you can take advantage of this excess heat.
First things first, assess your current dryer vent. Is it damaged or excessively dirty? The one in my house was in pretty rough shape when I moved in. I decided to replace it entirely.
If your vent duct is in good shape, it will probably just need to perform regular dryer maintenance. I use the dryer sweep shown below to reach debris in in the dryer vent and lint trap. Compress the duct along its access to make it easier to clean, if needed.
