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.
