Mounting Central AC unit on side of home

Similar arrangement is used in my area because of flood plain. Check for vibration transfer to house structure. TB

In my area most new installations are using a compsoite plastic pad rather than concrete.

That's they way it was set up on my new home (ten years ago). I had to do some adjusting to eliminate the vibration issue. I still get a small amount of vibration, but not much now.

I suspect they did it because it was cheaper than building a proper pad. If I had it to do over, I would put it on a good pad.

No comments on mounting, but why do you want to do this and beware of sound/vibration transfer.

P-nut,

Be sure to check on local zoning. Even with much more quiet units these days, many communities still have old ordinances which forbid putting the units on the side of the house.

Good luck, Gideon

Thanks to anyone that can point me in the right direction.

Why?

I concur, why? Is there some specific reason for doing this? Hanging a appliance is extra work and adds new issues (vibration, support). Make sure you are not doing it for "because everyone else is doing it".

I want to move my AC to the side of the house and remove the pad for additional room/less noise for the new deck I will be building in the next month or so. Mounting it sounds like it's a bad idea hearing from everyone so far so I might just pour a new slab on the side of the house.

Ok, that makes sense. Don't want to build a deck around the condensor (as shown on some HVAC sites as what NOT to do). The HVAC guys can confirm this but I don't see you needing a poured pad. Heck some places use plastic types. Check with your AHJ for local regs of course.
