Hello, I could not find any data on that model number under Lennox or Lear Siegler, or in generic searches using the model number.

There are ways of determining the cooling tonnage though. Get me all of the numbers from the plate spot welded to the top of the compressor. We can go from there.

If you can read the units model number name plate it will have the condenser and evaporator motor data, voltage, phase and HP or full load amperage, that can serve as a double check on the unit capacity.
