Don't like the smell when the AC kicks on? Tape a dryer sheet over the vent for a fresh aroma. This works for window units and in-ceiling or in-floor registers. You don't need to block the vent entirely or your dryer sheet may end up across the room!
When you're carrying in groceries, struggling with a latched door is impossible. Wrap a strong rubber band over the inside knob, flip it to form an X, and wrap it over the outside knob. Now you can go in and out freely and remove it when you are done!
