Why is my furnace clicking when the furnace is sour.? I need someone to fix the click coming from my furnace....

I need someone to fix the click coming from my furnace. It clicks but my carafe stat is not even on. It's set to the "off" position. How much $$ to look at it and repair it? I don't know where to look to fix this problem.

Answers:    Your furnace should be checked by a professional every 2 years if furnace simply. once a year if a/c also should be under $100. But in good health worth the money if there is a problem next to any CO2 leaks.
