That is the question. I need a new central a/c unit and have a 19 year old Lennox pulse furnace that completes my system. As far as I know, there is nothing wrong with the furnace other than age. I have been told that these furnaces had some heat exchanger issues and there was a major recall. I understand there is a pressure test that can be done to determine if the unit qualifies under the recall program.
I am trying to decide whether it is worth replacing the furnace at the same time as the a/c given its age and tendency for failure. I hate to spend money now on something that could last 2, 3 or 10 more years and with its 96% efficiency rating, I probably do not stand to gain a lot in replacing it. However, I also do not want to be left in a no heat or dangerous situation.
Thoughts, advice, suggestions??
