Gas Leak? Natural Gas Furnace Help

5 years ago

I have a central HVAC - natural gas furnace.


Currently I am still running A/C and the furnace as not on. However, I sniffed the air intake for the furnace and I get an odor of natural gas. The unit is in our garage and it intakes the air from the garage...exhausts to the outside.


Is it normal to have a light odor in the furnace when it is not running?

If not, I assume there is a leak?

If there is a leak, without testing, what would be the most likely issue? Valve or manifold?


I have ordered a gas detector, but I am looking for knowledge on the subject.


Thank you in advance.
