Recently you set your clocks back and checked your smoke detectors. Whenever time changes take place catchy sayings like 'spring forward and fall back' help us remember exactly what to do. They also can serve as a reminder that it's time to do other things, as well, like checking or changing batteries in smoke alarms. But why stop there? Here are a few more things you should do every fall and spring, and there's no better time than when you "spring forward" and "fall back." Start by replacing filters in furnaces and air conditioners, and then change the direction of your ceiling fans. Blades should turn clockwise (reverse) in winter on the slowest speed to force warm air down. This distributes heat gently without causing a draft. And remember to reset programmable thermostats. Do these things now and again when we "spring forward." And that's the On The House tip for today.
