Think my central AC has blown a fuse but I have no fuse puller--hardware store out. Is there some other tool I could use or should I wait til I can get one? It is New Orleans and real hot.

My air conditioner has stopped...conditioning. I live in a condo on the north side of Chicago in an old conversion building. The furnace in my mechanical closet hooks to a AC unit on the roof, and for the last few days, it's been running full blast and can barely keep my unit below 80 degrees. I checked on the roof unit, and the fan is blowing cool air out. At this point, I'm pretty sure I need to call in a HVAC guy, but even the best reviewed places on Yelp are combinations of THANK YOU FOR SAVING MY LIFE and OMG SO OVERCHARGED. So, mefi, what do you recommend? If anyone here has any expertise in the field, I'd love to know whether you think this is something simple like a coolant recharge, or I'm looking at a new AC unit. My best guess is that the AC is about 5 years old, give or take.

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.
