What is the heat exchanger, and can they be replaced.?Post created: 2014-11-04 Type of Equipment: Furnace Views: 170
Installed in 2001, it is an Amana 90 Air Comand Gas Furnace. The problem started this week. A tech came out and turned it back on.

A heat exchanger allows for the exchange of heat between two fluids (air or gas) without the fluids mixing together. The heat exchanger can be replaced and most warranties have lifetime or at least 20 year guarantees for them.
