Replaced 1 2 Stage Lennox 4 ton, 1 2 Stage Lennox 2 ton, 1 2 Stage Lennox 3 ton three years ago all at the same time. The original units were 30 years old, narry an issue for all 30 years besides one cap.
Since the replacement, metering valve on the 4 ton coils had to be replaced, then the compressor bit the dust, and most recently the coils sprang a leak and were replaced. All under warranty, but didn't include labor and Freon. The 2 ton has a leak in the coils and will be worked on next. The 3 ton is upstairs and doesn't get used that often so it may or may not have an issue.
The remaining "old" unit is a RUUD 3 ton single state we replaced in 2003. Not a single issue from it from day one.
The only advice I have is brand. Lennox is not what is used to be!

Its been stated numerous times but cant stress enough to stay away from Lennox. Any company that recommends Lennox is suspect.
Trane is tops by a large margin. American Standard is good too. Carrier and Ruud are solid. Goodman is solid as well for first 5-6 years then you will have issues.
Yorks are basically a cheap repackaged Coleman unit. Bottom of the barrel. The old York commercial units are very good, the old york residential units on R-22 were very good. Still many of the those 26 yr old dinosaurs around. However the newer Yorks made in past 8-9 years are terrible.
A couple years ago my house was 2,450 sq ft with 3 16x20 returns. I had a 5 ton 14 Seer Trane installed, all new ductwork, electronic dampers for zone heating and cooling, new disconnect box, surge protector, new gas lines, 2 new nest Thermostats and total came to $7,600.
That baby ran like a champ. Could be 102 degrees outside and would keep the house ice cold at 60 degrees if desired.
Having enough returns is critical though. We moved to a new house with two 6 yr old Yorks. Upstairs had leaky evaporator coil, fixed that, but still wasn't cooling properly. Had 58 degrees out of vents, so we added another 12x24 return and temp dropped to 54 degree out of vents then outside unit is 3 ton and evap coil is 4 ton but they put wrong expansion valve in when building house. But correct one in and temp was 50 degrees coming out of vents.
