There are several things to do when the time changes and it starts with setting all the clocks and changing smoke alarm batteries. Over the years I have add other home maintenance chores to the time change day. I recommend you change the air filter. Make sure to check the size before heading to the hardware store. I also check and make sure you have an operating fire extinguisher and make sure everyone in the family knows how to operate it. Also be sure to reset any items on a timers like; outdoor landscape lighting, any recycle pumps or light timers.
