    cleaning condensers

    Has anybody got a good trick for blowing out condensers , espeacially on self contained units, where the dust is contained instead of blowing all over the kitchen or where ever you are? I use co2 and a wet towel over the back of the condenser but still it doesnt do an adequate job of containg the dust. A vacuume don't work either.Who out there has a good way. Also thanks to all for the help on the freezer. we are gaining, got er down and holding 8'.

    Nope,, gotta blow that dust all over. Only way.

    Well, at home I use a small bottle brush. Then blow the heck out of it with my air compresser and tell the wife to cover anything she does'nt want covered in dust

    PS, I tried a vacuum cleaner once,, but it took more than 5 mins, so I blew that sucker out!

    The pharmacies I do, I use the brush, then nitro with a vacuum trying to suck the crap out of the air.

    I didn't say it worked the best...but that's what I do.

    Use a damp rag behind the condenser, then the dust will mostly cling to it.

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    What I do -

    Take a shop vac in and set the hose near the compressor and fan motor. Cover the whole unit, except for the condenser inlet, with a large wet towel or cotton tarp. Turn on the shop vac and blow out the condenser with 150 lb. nitrogen pressure.

    I've had a few like that in some restaurants. I just unplug them, roll them over to a floor drain and wash them out with my Coil-Jet cleaning machine. No muss, no fuss and it's nice and clean.

    I use cans of coil cleaner/degreaser. Foams real good, pulls grease off, washes clean with water hose.

    Water and a wet vac, or CO2 and a wet towel. Tell owner not to wait until they are plugged if they do not want mess.
