The home itself is a different place on Shabbat. The radio and television are silent. The phone is not answered, the computer isn't used, even the alarm clock stays in the "off" position. Basically, no electrical devices and appliances are operated on Shabbat. Lights, heaters, and air conditioners are turned on before Shabbat, and are not manually turned on or off during Shabbat (timers can be used to turn them on or off at preset times).

Most household chores — such as heavy cleaning, gardening, doing the laundry, or making repairs — also fall under one of the categories of work from which we refrain on the day of rest.
