    I generally use the eccentric termination kit. Only one wall penetration. I would agree that a nice air cleaner would have been a nice add on to that G71. Also, I don't see a vent tee on the furnace...

    I don't think that Lennox match up you listed will make the tax credit either. Looks like 17.2 SEER and 12.70 EER.

    Thanks for the clarification. This coil # doesn't exist however, and the SEER rating still isn't 19 even with a matched coil as the OP believes. I think a little more homework is in order.

    Make the call. The sooner the better. Refrigeration systems absolutely hate being left open to the atmosphere. And DONT start the system until the repair is made.

    I like the XP15 for quiet operation as well as the warranties. If I were in the market for 2 stage I would choose the XP19 over the XP16.
