To reduce the risk of carbon monoxide poisoning, have your heating equipment “tuned up” each year, preferably before the heating season begins. Your local gas orelectricty company has highly trained professionals who can provide this service. The service technician should also check your chimney and vent pipes for blockage. It is also a good idea to make sure your home is adequately ventilated, particularly if you have added insulation to your home, had major renovations done or have enclosed your heating system to increase living space.
