Woke up to a freezing house this morning and the furnace was making this awful grinding noise. Called an emergency repair service, and a technician was at my door within an hour. He found a cracked heat exchanger, which explained the smell. Grateful for fast help, but now I'm looking at a costly replacement. Winter really hits different when your heat goes out.
