High-efficiency furnaces draw combustion air from outside and exhaust through PVC pipes. Snow, ice, or debris blocking these pipes can cause dangerous carbon monoxide buildup or system lockout.

Test CO detectors monthly and replace batteries or units as recommended. Install detectors on every level and near sleeping areas. After any significant snowfall, walk around the exterior and clear snow or ice from intake and exhaust terminations.

Have a technician inspect the heat exchanger and venting during your pre-winter tune-up. Cracked heat exchangers are a serious safety concern.
