Air conditioner

The wife wants to put a cover over our air conditioner (central air conditioner) for winter. Is that advisable or will it just trap moisture? What do you do? What do the pros advise?
 

Why?
Has someone removed all of the exterior sheet metal??

Maybe a sloped roof shelter about a foot above would be good to keep the snow from piling up on it and the rain and sun.
For the months not used.
 
I've never covered one, and can't recall seeing anyone cover theirs.

They are designed to survive outdoors. About the only thing I have see cause them damage is dogs peeing on the aluminum fins causing them to corrode away. Depending on the type trees nearby, they will collect leaves inside, but it doesn't seem to hurt anything.

I can't cover mine, it is a heat pump.
 
Depends on where you live. We get a lot of dirt and tree trash in the AC in fall and winter so I cover mine. Wouldn't worry about moisture, they are damp anyway.
 
I used to cover mine until one spring I uncovered it and found a mouse nest inside the cabinet. since then I just lay a cover on top to keep snow from building up inside, seems to work well. I also remove the sheet metal once a year to clean the condenser fins. Unit is 24 years old.

I do what Double07 suggests. I built a slope-roofed little "hut" that I place over the unit after I clean it each fall. It leaves air space all around the unit and keeps out snow, branches and leaves. (My property has trees and bushes everywhere.) In the fall, I lift off the hut and the unit is clean and ready to go.
 
Old trash can top strap over the fan. Seen snow get deep around the fan motor. Fill motor full of water. Cause snow falling off roof filling unit up.
 
Hello Ted in NE-OH,

It wont hurt to cover it, as in time dust and leaves collects on the bottom. Together with rain it clogs up the drain slots. Bet you it you look close enough you will find them.

You can blow them out from the outside, but a better way is to blow then out from the inside.

A vacuum cleaner does a better job though.

Pull the disconnect switch first. Here is where the drain holes-slots are on mine, they usually at least two of them.,

I am not a pro, but have seen enough mice get into "covered" items over the years. A small shelter roof as others have suggested sounds like a better idea.

A few years ago when we had a lot of snow and then a lot of icicles at my church we had an ice mass fall on one of our evaporators and crush it.
 
HVAC guy advised me that you should only cover the top to keep ice & snow from getting into the fan/coil assembly. He stated that he's seen quite a few condensers that had wiring chewed up because mice like dark secure places and they get under the a/c wraps that you get at the home stores.

Plywood and a brick are your friends.
