I would check out the ducting like you with any forced air system. Make sure that the air intake is not plugged and that it is filtered before it reaches the blower section. With any out side air intake you want to keep 10’ clearance from any flue exhaust or waste vent.

Look for signs of soot at supply registers and smell for oil or gas fumes. Observe the burner flame as the furnace fan kicks on; a disturbance or color change in the flame may indicate air leakage through the exchanger. I like to be there when the unit fires up, to see how the flame reacts upon igniting.


Operate the furnace for several minutes and then feel the furnace cabinet for uneven hot spots.

David,


Not trying to be a know it all here by any means. The question was about air exchangers, not heat exchangers. Air exchangers are connected to a home duct system as well as to the outdoors to provide a constant, controlled supply of fresh air to the home.

The post previous to yours is just about what I have done on any of the units I've ever seen. Haven't seen any since I left VA!!

BTW, your answer on heat exchangers was good!

OOOOpps.

I really have to slow down a bit here. I'm reading way too fast.

Erase my last statement....![](upload://kPfCTIr2MvAiQ548DCSC1ILbXLt.gif)
