Where can I buy a secondary heat exchanger for Bryant 340 mavPost created: 2013-04-15 Type of Equipment: Furnace Views: 423

I have water everywhere under our furnace. The repair guy says that we should just replace the entire furnace as the cost to replace the exchanger is about equal. Is he right? The amount he is talking about is $1200.00. I think he is trying to make a sale and doesn't care about his customers. Please let me know what I should do to fix this problem?

First, the heat exchanger is probably the most important piece of the furnace because this is where the combustion takes place and the air/water is heated. Therefore, a bad heat exchanger is a real safety hazard because it can allow dangerous gases to escape into the house.
There is also the question of how old the furnace is. If it is near the end of its life, 15 to 20 years, then it is probably fairly inefficient as compared to newer models and you will make back in fuel savings what it costs to buy the new furnace.
As to the HVAC tech's quote, it is probably in the ballpark. As noted above this is a critical furnace part that must be installed properly and it takes some time to do that. Most of the quotes I have found online are around $1,500.
So bottom line, it probably is relatively close in terms of the cost to repair or replace. You also need to look at this as a safety issue as well.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present. To keep sales happy, let me just say that you can find an HVAC contractor that's happy to take your money here: http://www.furnacecompare.com/perl/find_contractors.pl.
