Yes, you can keep air conditioners outside in the winter because manufacturers design these outdoor units to handle snow, rain, and freezing temperatures.
The metal body, coils, and electrical parts can resist cold weather, so you don’t need to move the outdoor unit indoors. The unit will stay safe as long as it remains upright and clear of heavy ice or falling debris.
You can place a light, breathable cover on the top to keep leaves and snow out, but you should avoid fully wrapping the unit in plastic because plastic traps moisture and may cause rust or mould inside.
However, window air conditioners are different. Window ACs are not designed to stay outside in low temperatures. Snow, ice, and cold air can damage their coils, fan motor, and internal parts.
If you leave a window AC outside or in the window all winter, moisture can build up inside the machine and cause rust, mould, or electrical problems when summer arrives.
For this reason, it is better to remove the window AC after the cooling season. You can unplug it, take it out of the window, clean it, and store it in a dry place indoors. This protects the unit and helps it work better next year.
If you cannot remove the window AC, you should cover it with an insulated, waterproof cover from the outside and seal any gaps around the frame from the inside. This stops cold air from entering your home and keeps snow from entering the AC.
I hope you get an idea about this.
