Can a Window Mounted Air Conditioner Be Used When It Rains?
The answer is yes it can.
All HVAC heating and cooling units are designed to work in the rain and other weather.

Lightning strikes can damage an A/C unit like any electrical device so if a huge storm rolls in it may be a good idea to unplug it.
Also if the power is going On and Off from a storm it could damage the compressor if the unit is running.
If the unit leaks into a home then it has not been installed properly and the installation should be redone correctly.
Fixing a leak around a unit should be done immediately as water can damage the internal structure of a home.
Rain can also drip onto a unit making loud dripping noises which can be fixed easily with a low cost Rain Drip Cushion.
Rain Drip Cushions can also help prevent damage if Hail was to fall, although building a small roof for the unit would be a better option.
