Here's the story, my current system is a 2.5 ton AH w/ 3.5 HP and its on its last legs so looking to get it replaced.
So far i have I have been told to get a 2 ton HP and AH but the other guy says 2.5 ton is better. I currently live in a small townhome which is 1200 sqft but has a basement not including the sqft. I reside in MD so temps can get about 15 degrees at lowest to 90 degrees avg in summer. The system I'm looking at getting is a 2 stage HP w/ variable speeds AH. Dunno if that makes the difference in size. They both are quoted in about same price rance as one is a Bryant Evolution and other is Trane (don't recall which model thou.)
