Questions
What should I do if my furnace stops working in winter?
Check the thermostat and filter, then call a technician. Do not heat your home with a gas oven, which can fill the home with carbon monoxide. If you smell gas or a CO alarm sounds, get outside and call 911.

Where should carbon monoxide alarms be installed?
The CPSC recommends battery-operated alarms or alarms with battery backup on every level of the home and outside sleeping areas. Interconnected alarms work well, since when one sounds, they all sound.
