Lennox G25MV Heat Exchanger.

Used. I see no cracks. This was removed by myself when the system would not work. I later discovered the fault was that the (now obsolete) NOx insert baffles had worn out, but by that time, I had purchased a new exchanger.

Local pickup.

Shipping could be an option and I could box up the item and take it to UPS but buyer will be responsible for all interaction with the shipper, and all fees paid for the shipment. It could potentially be very expensive. Or Uship.com
