My AC guy says Trane has more proprietary parts than most making service more expensive and sometimes delaying it as well.
Well, Goodman's residential line was formerly known as Janitrol.

One thing that I am a little surprised about is the low number of votes for York. George Brazil seems to heavily advertise York A/C systems on TV. The high number of votes for Goodman, Carrier, and Trane aren't surprising though.

Here is a question I've really been wondering about AC's out there. In the southeastern US, much of the AC's duty is to remove the moisture out of the air. And if you buy a unit that is too big, it shuts off before it has hardly had a chance to "condition" the air. This is the case with my 18,000 BTU unit in my main room. It's great in the summer, but many months it is overpowered, the thermostat clicks off and the place still feels muggy. I wind up turning the temp WAY down so it will run more.

But...out there the air is already dry in the house. So what would happen if you had a unit that was way too big? It seems to me it would quickly cool the house down that's all!

And another thing, the motel I stayed at out there had a nice new commercial wall unit. When the compressor would shut off and the fan would run, I didn't notice any of that typical musty smell like I do with my own. It could be because the motel had a real high quality unit, but I'm thinking with that low humidity, the mold can't even survive in the evaporator coil.

If the unit is too big, it will "short cycle", which uses more energy & cuts the efficiency. You'll also get "hot spots" in the house, because the air isn't circulating. I've never seen a moldy coil here, but your a/c unit does still need a drain, and it will drip a surprising amount of water in the off months.
