Checking for Gas Leaks in a Furnace in Houston, TX

FURNACE STORY: We were called out to a house near downtown Houston, TX where the customer stated that their home was filled with the smell of gas.  They did the right thing by evacuating and calling centerpoint.  Centerpoint came and performed a test on the home finding gas coming from the furnace.  They shut the furnace down.

A common reason to replace furnaces is when the Heat Exchanger has a crack.  In this case no crack was found in the heat exchanger.  The following picture is from during the diagnosis process.
