Wooden Platform for A/C Compressor Unit
 

Is it against code to install an A/C compressor unit on a wooden platform instead of a concrete slab? For space reasons, I will need to relocate my unit when it needs to be replaced, and building a 30"x30" wooden platform for it would solve the space problem.

don't know about code violations, but that is what I did. In order to have my condensing unit above my A coil I had to build a wood frame. Attached it right to the foundation of the house on one side a sank 4x4 posts into the ground for the other side. Neat and compact.

Not against code here.

You have to check your local codes. That wooden frame is a big no-no in gulf coast states. They must be anchored to a concrete pad.
