I would go with a lennox.

the OP asked for quiet and servicable lennox is at or near the top on both points.
Thanks. I am not aware of this. Last I heard on this forum, Rheem/Ruud is claiming to have the quietest gas furnaces and I don't think there is any outside unit easier to access then a Rheem/Ruud rectangular unit.
