I was wondering if anyone has any experience with LG Multi-zone air conditioners? We have a multi-zone system that has been working fine until recently. Now, when I try to run the AC I get a flashing CH 26 and CH 46 error on the units. They work fine if we just use the fan settings. Do I have a bad compressor/inverter or is it something worse?

Help me keep cool! Ok, I'm a bit OCD about this I realize. I'm wondering if there's some way to test the AC in my apartment to see if it's working properly. Is there a special thermometer to use to test the air temperature coming out of the vents? If so, what should that temperature be? [more inside]

Ten-year old air conditioner, busted compressor. Get a new compressor, or replace the whole thing? [more inside]

I need to install a window air conditioner in a casement window. (The kind that cranks open sideways, instead of sliding up and down) If you've ever done this, I would appreciate your thoughts. I do know I need to buy a special model AC.
