5 Common Problems With High-Efficiency Furnaces
A high-efficiency condensing furnace is a little more complex than a conventional furnace, and troubleshooting is somewhat more complicated since there are more potential problems. High-efficiency furnaces are often known as condensing furnaces because they have a second heat exchanger that extracts additional heat from the air that passes through the first heat exchanger. This heat-extraction processes caused water vapor to condense out of the air, which is drained away through a tube that is usually placed in a floor drain. Thus, a high-efficiency condensing furnace can be identified by the presence of this drainage tube.
