What do I do if I suspect CO is present?
  1. Open windows to ventilate the area.
  2. Shut off your furnace and other fuel-burning appliances.
  3. If you're experiencing physical symptoms, get everyone, including pets, out of your home or building.
  4. If you have an attached garage, open the largest garage door.
  5. If you suspect problems with your appliances, call your gas appliance dealer or CenterPoint Energy's Customer Service toll-free at (888) 876-5786.
  6. If CO is discovered, don't return to your home or building until the source is found and the problem corrected.
