I've noticed that my brand new AC condenser is forming a puddle of water underneath it while it's cooling on a hot day. This isn't water from the drain line; it's coming directly from the condenser itself, and it's quite a bit of water. It's pooling on the cement pad, and I'm worried it could lead to rust and mold issues on the unit's feet. If the AC is effectively pulling heat from inside the house, I'm confused about why water would be condensing on the hot outdoor unit that's actually hotter than the surrounding air temperature.

It sounds like what's happening is similar to how a cold can of soda sweats in the heat. The condensation is likely coming from the suction line, which is the refrigerant line that’s not insulated where it connects to the compressor. That's normal; the uninsulated part cools down and causes condensation that drips and forms a puddle. It's no big deal—your unit is working fine!
Is there any reason not to wrap that with foam insulation so it stops sweating like that?
Thanks for the clarification! I'll check that out next time. Appreciate it!
