A clogged lint screen or dryer duct drastically reduces the efficiency of your dryer, whether it’s gas or electric. Clean the lint screen after each load and clean the exhaust duct once a year. The cleaner shown here has an auger brush that attaches to a drill to clean out the ducts.

Clean Out Lint

It’s available at home centers. Dry loads of laundry back-to-back so the dryer doesn’t cool down between loads (a warm dryer uses less energy). And only run the dryer until the clothes are dry. Overdrying damages your clothes and runs up your electric bill. If you’re in the market for a new dryer and already have a gas line in the house, go with a gas dryer. A gas dryer is more efficient.
