wife and I are in our 3 yr old 'new' 2 story, '2 zone' house. our two
outdoor AC units (condensers? evaporators? I forget what they're called)
are continuing to "lean" like the leaning tower of pisa...I'd like to
fix this, & have some ideas, but I'm WIDE open to other suggestions.
please see images of 'the situation' we got at
to reply, please remove the "weird stuff" from my email address. thanks.
They just threw a couple precast pads down on the loose dirt when they
installed those puppies, didn't they? Now from rain/frost heave/vibration
when the units are run, the things keep shifting on you. Cheap solution-
soak the ground till the pads level and stabilize, and then stuff 4 bricks
under each box to keep it up out of the weeds. Correct solution- evac
system, have units disconnected and moved out of way, and pour a proper pad
over gravel base, or at least dig out and put gravel under the cheap precast
pads so they aren't floating so much.
By the way- those home-made leaf guards block a lot of air, and are costing
you money and operating efficency. I'd leave them off till leaf-dropping
My boss just bought a new home this year (over $300k), and they set his
condensor on a hollow shell of cheap plastic that looked like a cement
pad, until his lawn service took a chunk out of it. The property was
apparently filled in and is sinking around the sump pump discharge (not
aligned with drain) and also sinking rear patio that cracked and sloped
more than intended. It looks like chimpanzees did the caulking,
fortunately it matches the color of the plastic siding.
Even a cement pad may heave some every winter if it does not extend down
past the frost line. Although, at least a proper sand and gravel base
(proper drainage) under a shallower pad can help.
We noticed that his neighbor's condensor is mounted on angle iron, with
proper angled supports, anchored to the foundation wall.

from the pictures it looks like they used premade concrete stepping
stone instead of pouring the concete into a pad to place the a/c unit
on( its the condenser unit that is in the outside...the evaporator is in
the attic).... i had my single a/c system, 3 tons moved about 6 ft.
and we poured a new concrete pad.. maybe you need to do this and make it
higher when you do...
