I ran your # its a 31,000 btu straight cool unit
Its 12,000 btu per ton so its a 2.5 ton unit! good luck on the new unit

Unless the indoor coil had a TXV installed, an HS6 system would have used the Lennox RFC line as the metering device, so you likely must have new refrigerant lines installed with the new outdoor unit and indoor coil.
