Cost Savings

Checklist Tasks

• Locate all exterior exhaust vents serving home appliances.
• Inspect vent terminations for ice or snow restricting airflow.
• Carefully remove ice from vent covers using a non-metallic tool.
• Check for condensation or frost inside vent pipes for early sign of blockage.
• Test for warm airflow at vents while appliances run to confirm clear passage.
• Listen for abnormal appliance noises that may indicate restricted venting.
• Install vent hoods with downward outlets to shield vents from snow and ice.
• Clear a 3-foot area around each vent of snow, ice, and debris.
• Inspect vent screens for ice buildup during freezing weather.
• Test carbon monoxide detectors near vented appliances for alerts.
• Document vents with before-and-after photos for insurance purposes.
• Call a professional if vent ice returns within 24 hours after clearing.
