The vibration passing through our terrace floor was dramatically reduced, and the noise almost completely eliminated! ok...strong odor, work reasonable well...steel spring encased in rubber works better, but cost considerably more.Just lift the compressor unit one corner at a time and slide under. Did not offer a lot of noise reduction but did eliminate some of the start-up 'bang' noise.

really helped cut the noise level Rubber Baby Buggy Bumpers. Smell fades away in a couple of days. Removed the vibration down to 80% once installed Didn't make any difference, wasted my money They reduced the vibrations a little but did not eliminate them.

My outdoor unit is a bit slanted due to the floor not being completely flat (pic below). However, I don't see any obvious structural issues. Is this something I need to correct? Perhaps by sticking a small piece of wood on one side? Refrigerant needs to flow through the coils evenly without too much interference from the slope of the unit. A level concrete slab with rubber pads between the unit and the concrete is what the manufacturers recommend. "Mostly level" is probably okay for a residential unit. Get a half-inch thick outdoor rubber mat and cut it into 6"x6" squares. Put single pieces on the high side and stack several pieces under the low side to bring the unit closer to level. Be careful not to kink or damage the refrigerant piping to the unit when you do that.

If you damage the lines when you raise the unit to insert the pads, you will wish you had left it alone. It should be as level as possible. The previous posts make good mention of rubber mat 6x6" squares and careful approach to only tip the unit as little as possible not to kink any lines. If you don't hire a professional and aren't confident by yourself to address the issue, having a second person watch the lines while you tip can save much potential trouble. Previous information from these posts also generate ambiguity over the importance of having the unit level in regards to the compressor. Leveling the unit will terminate any ambiguity. An additional concern not previously adressed is the compressor and/or fan bearings. An off level unit will put additional unintended mechanical stress/strain on these rotating components long-term. Therefore for best performance and longevity of your unit, level it and take special precautions in the process. Outside A/C compressors are typically supported on a concrete pad, concrete blocks, or a vinyl pad such as the one shown in the photo at page top.

The air conditioner compressor support pad should be level and secure against movement. Compressors which are badly out of level may fail to function properly and need adjustment. Tipping and moving compressors can also cause can cause leaks in refrigerant lines, leading to costly air conditioning service calls to evacuate and recharge the system after repairing the refrigerant leak. Do not try to move your A/C compressor yourself as you might cause a refrigerant leak or may otherwise damage the equipment. For slightly-tipped air conditioning compressors we generally leave them alone but we add support as needed to avoid further movement. Not being level can cause the oil for the compressor to not lubricate correctly. Over time it will cause the compressor to burn out costing you lots of $ in the long run. For a professional appearance it should not appear to be set without a thought to anything but function as if a war time situation where getting online asap is the priority.

The thought that an AC unit must be absolutely level or its wont work or work well is based on absorption type systems RV's used in the old days that used ammonia and a flame rather than a compressor. Technically speaking, no it matters not if its level or even close to it, it can be at a slant but will look weird. Our unit was off level quite a bit which caused damage that first caused it to perform badly before it quit completely and had to be replaced prematurely. It was installed in 2000. My outdoor a/c fan, condensing unit was making a metal sound when going on and off, that I thought was too loud. The fan blades seemed OK. I checked to see if the unit was level, and it wasn't. In fact it was quite a bit out of level. I leveled it, and now it is very quiet.Eliminated vibration from free standing AC condensorWorks well for isolating a washing machineI ordered two sets, which gave me eight 2x2 squares.Amazing anti-vibration padsHelped me figure out the source of the vibration...not as straightforward as I thought...but solved the problemUsed under hydraulic pumpLooks like they will last.
