Should I cover my air conditioner for winter? It's difficult to find an appropriate cover, but finding a cover for an evaporation cooler is easy (and because they allow for air flow from the outdoors, it makes sense).
See this answer for things to do before winter hits, where it's not clear whether an air conditioner should be covered or not.
I don't want to let water build up inside and given my climate, it will freeze and thaw repeatedly which can be very damaging. On the other hand, I don't want to create a moisture barrier that leads to other problems.
Any official word on this?
