To top it all off, this morning we found the condensing unit for the central A/C had been blown off the mounting pad! That's a new one, I'd never seen that around here or anyplace I've lived. ....
Wow. We had high winds here recently, I will check ours. Our new one is a high efficiency unit, and it is LARGE to provide a lot of surface area for the fins, so it seems pretty light relative to the size, so the wind could have a bigger affect on this than the lower profile unit like yours (and our old one).
I'd def consider some posts into the ground to tie it down.
