Preparing for Heating Season: The Maintenance That Prevents Carbon Monoxide Disasters
Fall preparation ensures safe, efficient heating while preventing dangerous conditions that cause 400+ deaths and 20,000+ emergency room visits annually from carbon monoxide poisoning.September Heating System Preparation:
Gas Furnace Safety Inspection (Critical - Cost: $0-$200)
1. Visual Safety Check - Inspect heat exchanger for cracks (use flashlight) - Check venting system for obstructions - Look for rust, corrosion, or damage - Test carbon monoxide detectors (replace batteries)2. Combustion Air Supply - Ensure adequate air supply to furnace room - Check combustion air openings for blockages - Verify proper clearances around unit - Remove any stored items near furnace
3. Gas Connection Inspection - Check for gas odors around connections - Look for corrosion on gas line - Test gas shutoff valve operation - Verify proper gas pressure (professional task)
When to Call Professional Immediately: - Any gas odors near appliance - Rust flakes around heat exchanger - Yellow or orange flames (should be blue) - Soot deposits around venting - Previous carbon monoxide alarmsOctober Heating System Optimization:
Ductwork Preparation for Heating Season
1. Seal Air Leaks (Saves 10-20% on heating costs) - Use metal tape on visible duct joints - Seal around duct penetrations - Insulate ducts in unheated spaces - Close summer cooling vents in unused rooms2. Heating Distribution Optimization - Reverse ceiling fans to clockwise rotation - Move furniture away from heating vents - Install door sweeps to prevent heat loss - Consider zone dampers for unused areas
