yes it does! Falling leaves as well as snow and ice can get into the condensing unit and cause damage.
Use a cover made of breathable material,Put plywood over the top of the unit only to shield from snow and ice, weighing it down with bricks or rocks to keep in place,Install a wood awning or shelter attached to the building that covers the top of the unit, Plant shrubs around the unit to protect from wind and blowing snow.
Make sure you "work" the juice in your laptop batteries by unplugging your laptop from a power source until it's at low battery. Keeping your laptop plugged in all of the time is not good for your long-term battery life. Also, be sure to eliminate the common drains on your laptop battery life by minimizing screen brightness, closing unnecessary programs and turning off Wi-Fi when not in use.
