Maybe they took it out in the 70s when they dropped the ceiling in the kitchen

Best spam title for the past few months: "ductwork accelerometer." Thursday there was a note outside my door from Zoned Girl that the furnace had gone out, did I have time to look at it, or what was the landlord's phone number? Well, I'm pleased I'm #1 on the list of "people to poke broken things", but I was running late, and I really hoped she meant the hot water heater (again!), since I'm not so keen on clambering around under the house poking things. Left her the number and the location of the long-necked lighter in case of water heater, ran to work.

Friday, landlord came and fixed the furnace, which apparently had loose wires (under the wood and plaster house from 1905, oh what joys of insurance I need a fire extinguisher). Saturday it went out again (cold!). So I'm paging through my email on the web to nail all the spam before downloading and reading mail, and I see "ductwork accelerometer," and my first thought is, Dammit, not the ductwork accelerometer, too!

This house totally seems like the kind of place that would have a ductwork accelerometer.
