Hey guys - I've gotten several quotes to have our AC unit replaced and after weeding out the high/low quotes, I've narrowed down the potential vendors that we may go with. All have relatively similar warranties on the labor, parts, unit, etc. so it seems like it's a decision between the models themselves. I'll be going with either a 3-3.5 ton unit. Do any of these models stick out to you as better/worse than the others: Lennox 13acxn, Lennox xc13, trane xr13, Bryant 113ana, or carrier 24abb.

Thanks guys!

Please read the links below, they should answer all of your questions. Note that a larger tonnage unit should not be considered an upgrade. Bigger, as far as HVAC goes, is not better.
The duct system needs to also be assessed to verify it can move the the quantity of air discharged from a 3 or 3.5 ton unit.
