More apartment drama today. I've been getting little headaches lately and noticed that the heat was always on when I got them. When the heat turns off the headache would go away. I tried four times to call the gas company's emergency number. Each time I called a recording would say that they were too busy to take my call and to call 911! I am always reluctant to call 911 for anything except a real emergency, but I don't wish to perish in my bed due to carbon monoxide. A fire truck arrived, lights on, sirens blaring, and three firefighters came up to my apartment to check the carbon monoxide level. It was OK and they referred me to the heating contractor. They also said that low levels, below what can be picked up on their sensors, could be present and causing thr headaches.
