re: New Construction HVAC question

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.
