How Can I Tell If Heat Exchanger On My Gas Furnace Is Broken?

Posted by admin on December 9, 2009 under Heat Transfer | 4 Comments to Read

I have a high efficency gas furnace that runs good. But after it shuts off a little water leaks from underneath it. The pcv vent, drain and pump are fine. Does this mean my heat exchanger is broken or could there be a loose hose connection inside the furnace?
