Does AC compressor need rubber pads?

[cgallery]

I had someone mention to me that that AC compressor that is sitting on my concrete walkway outside my house should have rubber pads underneath it. I've included a picture. He said I should just get some rubber and put it underneath the four corners. Is he right? How thick should it be? Where do I buy it? I don't want to put undue stress on the connections by moving it too high.

And those seeds are a PITA. I just cleaned them away from the unit the day before but the tree is dropping seeds like crazy.

TIA,
Phil

I don't know if it's needed or not but both of my units are sitting on 4 "cones" that keep the whole unit up off the ground about 4 inches or so. If yours were up on blocks or whatever you wouldn't be having the problem with the seeds piling up around it. They would pile up somewhere else, maybe your neighbors...

They are usually installed on a pad, which yours is. Most have 4 feet on the bottom though...

Both of mine are on concrete or composite "pads" on top of dirt.

While yours appears to be on a pation or something, I would think you would want some pads or feet to keep it above the water if it rains real hard for a short time, also would keep stuff from piling up against the vent areas.

Exactly. I called York and they said they don't include rubber feet of any sort, that they are intended to sit right on the concrete. But I think they normally sit on a "pad" and are therefor elevated 1.5-2 inches over the surrounding grade. I'm going to go to the HW store tomorrow and see if they have any sheets of rubber that I can make something out of. The piping is all flexible, so I should be able to lift the thing up a little bit.

Thanks everyone!

It doesn't need to be rubber. The compressor inside is sitting in rubber mounts to absorb the shock. It does need to be raised though.
I would just get 4 of the 4" by 8" by 16" solid cement blocks and place them under one at a time. The unit really isn't that heavy just lifting a corner at a time. I'd lift with a crow bar or something though.

An episode of "Holmes on Homes" had Mike off on a rant and ended up with the AC unit on substantial brackets (angle iron) attached to the house so that it was up off of the ground and could be dug under for foundation and weeping tile repairs without having to muscle it out of the way, and then re-install later. He expressed an opinion that they should all be installed that way. That would also solve the blowing seed problem
