I used to work for a Lennox dealer and we used to never match a different brand condenser to a Lennox A/H. This was only true for heat pumps. I know it is better to do a complete change out, but some customers will only replace the defective component. Does this still hold true? Also, I can't remember the reasoning behind it. I think it had something to do with the coil size in the heat mode.
