Furnace tune-up helps prevent carbon monoxide danger

As the winter heating season approaches, consider getting your home’s heating system checked by a qualified heating contractor to help identify and address any carbon monoxide issues that could exist. Carbon monoxide (CO) is a poisonous gas that is odorless, colorless and tasteless. It is formed by the incomplete combustion of fuels such as heating oil, wood, gasoline, coal, natural gas, propane and charcoal. When heating units or motors are not working properly, or if exhaust fumes and chimneys are not properly vented outdoors, carbon monoxide can accumulate in your home. Breathing even small amounts of carbon monoxide can result in headaches, dizziness or nausea. Prolonged exposure can result in more severe illness, or even death. If you experience any of these symptoms, immediately open the windows in your home and seek medical attention. Call your heating contractor to repair the source of the problem. Some signs of a CO problem are: Stale, stuffy air with high indoors humidity. Fallen soot from a fireplace chimney or furnace flue. No draft in the chimney or flue. To prevent a carbon monoxide problem, make sure that a plumber or qualified heating contractor services your furnace each year before the heating season begins to: Clean and adjust your heating system’s thermostat. Check the flue for leaks to avoid carbon monoxide escaping into living spaces. Properly lubricate blower motor, fan motor and circulator pump. Check operating efficiency of heating controls. Replace cracked, worn or frayed blower belts. Clean or replace filter. Remove dust or lint from furnace vents, registers and cold air returns.
