Have a professional do the following: • Measure the concentration of Carbon Monoxide in the flue gases. • Check furnace connections to the flue pipes and venting systems. • Check furnace filters and filtering systems. • Check forced air fans for proper installation and to assure correct airflow of flue gases. • Check the combustion chamber and internal heat exchanger for cracks, holes, corrosion, dirt or debris. • Check burners, ignition systems and pilot lights. • Check fireplaces for closed, blocked or bent flues, soot and debris. • Check all venting systems to the outside of your home, including flues and chimneys for cracks, corrosion, holes, debris or blockage.
