Ever since we had the furnace fixed a couple of weeks ago, we've been smelling wisps of natural gas just as we walk in the front door, which is just off the kitchen. Today, I finally called the gas company. They sent a man out who identified a leak in the furnace and then turned off the gas. We called a plumber, and he came and replaced the leaky part. Our lives were saved!
We probably should have called awhile ago, but I just worried I'd be embarrassed that the guy would wave his gas sensing wand around and discover a dead squirrel or something under the refrigerator.
We recently got an estimate to replace the furnace with a much more efficient one. It was really expensive. Apparently what we're going to do instead is replace this furnace, piece by piece, and end up with the same inefficient furnace we already have, but at an even higher price.
