I didnt know this till recently but a gas furnace can pump out up to 1L per hour when running, this discharge is usually drained into the hot water tank overflow or another drain..
might be worth checking

I do have a gas furnace. I never really noticed any sort of drainage tubes coming out of the furnace. I'll have to take a look later today when I get home. This is an older house (probably 50+ years old) and there isn't any drainage in the furnace/hot water tank area so I'm not sure where it would drain out to.
We're beginning to suspect it might be a leak in the city mains before it goes into the house - and the recent snow might have been what clued us in to this. Our front yard has about 5-6" of snow everywhere except for this 3'x3' spot in the center of the yard. It just happens to be right in line with where the water mains from the city comes into the house.
Once the snow melts, we'll probably dig it up and check it out to see if that's where the leak is.
