Covering an Outdoor Condensing Unit


Hi,
I have an outdoor condensing unit on my back patio. It is only used during the summer when the air conditioning unit is on, 4 months max. The unit gets quite dirty due to the many trees we have in our area and the Evergreen Elm I have on the back patio. I do spray the unit down with the hose.

I would like to extend the life of the unit by purchasing a cover. Is this a good idea? I have read conflicting information.

Thanks,

Sycamore Inn

Covering an Outdoor Condensing Unit


Hi . its a personal preference i do alot commerical hvac and there units run all yr round and are in the weather elements and do not get covered , yes it will extend look of unit but will not extend the mechanical life of the unit , Keep up the maintaince you doing on condensor coil/unit

I don't do any maintenance on the unit. What type of maintenance should be done?

I think I read some place that covering the entire unit with a non-breathing material will possibly trap moisture inside and speed up the rusting process.

One HVAC tech suggested placing a piece of PT plywood on top to prevent stuff from falling in but leave everything open as it was designed to be located outside all year around.

Covering an Outdoor Condensing Unit


covering the top will add to the life of the condenser fan motor in heavy rain/snow areas especially when it sits til the next spring start up.if you have drift snow i would wrap it up to keep the melt away.give it a good hose washing from inside out cleaning all the leaves and muck from the compressor base(remove the top and slide off to the side reaching down ...easy on the hose don't need to blast it..Grainger has mild coil cleaners to spray on the "DRY" coil then let it sit to work in and comes out nice and clean.

Covering an Outdoor Condensing Unit


I know my neighbor covers his unit so I will talk to him as well. Most of the covers they sell today are breathable and designed for the unit. The unit sits on concrete and I spray around it often, so it gets pretty dirty. Here in Southern California we don't get snow, some rain, and our good share of wind, dirt, and leaves. I can get a piece of plywood that would be easy.

Thanks for the replies

I just take an old shower curtain, that just covers the top of the unit, and secure with old magnets from a couple of old hard drives, or bungee it on, leaving the sides uncovered.
