Leaving the Lint Screen Dirty
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 Linteater (shown) has an auger brush that attaches to a drill to clean out the ducts.
Electric dryers use about $85 of electricity annually. A dirty lint screen can cause the dryer to use up to 30 percent more electricity, according to the Consumer Energy Center. Lint buildup is also a common cause of fires.
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.
Forgetting the Furnace Filter
One of the fastest ways to create problems with a forced-air heating and cooling system is to forget to replace the filter. Locate the furnace filter and buy replacements if the previous owners didn’t leave you a stash. Replace the filter (and get in the habit of doing it every month). Here’s how!
Failing to Clean Air Conditioner Condensers and Evaporators
A little sweat equity now will help both your wallet and your comfort level later when summer’s heat sets in. Most of the job can be done without the help of a professional, and by servicing and testing out your cooling system now, you will have plenty of time to make an appointment with an air conditioning contractor if there’s any unforeseen issues. After cutting off the electricity to the unit, vacuum the outdoor condenser’s exterior fins with a soft-bristled brush, and clear away bushes, weeds and overgrown grass within two feet of the unit. Indoors, replace the furnace filter on the evaporator unit, vacuum the blower compartment, and clean the condensation drain.
