So I just went into my garage for the first time in 1-2 days and it smells pretty strongly of gas. This is where my furnace is. We rent, so I contacted my landlord to see what she wanted us to do (don't want to be stuck with an after hours service charge if we just go ahead and call someone and she'd rather us not do that). It's snowing and will be realllyyyy cold tonight, we turned off the gas...but neither me or FH really know anything about this stuff..any words of advice? I know gas leaks can be serious business but my google search hasn't been very helpful so far.
