Change the TXV

What does the engineering data from Trane tell you?

Yes Lennox used two different expansion valves there part numbers as I remember are 56J20 & 56J21 respectively. They are R22 TXV's. Not sure if they are the same number.

If you would like, I can run the load and see what I come up with. I use Wrightsoft. Just send me all the information about the house.

I don't believe that is a match please see attached.

You should be getting a rebate for the Lennox System especially with that setup. Better check with your contractor.

So no one actually took the time to measure your rooms, ceiling height, widows doors, whether you have carpet, wood floors, maybe some unusual room that has 50 computers, any overhangs over windows,...

Did any of these three companies offer a load calculation to properly size your unit with all the remodel? Not to mention to make sure your ductwork is properly sized?

Yes

Lennox HP29 has a 10 year compressor and 5 year parts warranty. I am not sure it is still possible to get an extended warranty though.
