Fall Furnace Preparation: Get Ready for Winter

Getting your furnace ready before cold weather arrives prevents uncomfortable (and expensive) surprises. Here is your fall heating preparation guide.

Fall Furnace Checklist

1. Replace the Air Filter - Start heating season with a clean filter - Stock up on replacements - Set reminders for monthly checks

2. Test Your Furnace Before you need it for real: 1. Set thermostat to heat mode 2. Set temperature above current room temp 3. Wait for system to start 4. Verify warm air at vents 5. Let it run for 15-20 minutes

Note: A slight burning smell initially is normal (dust burning off). Strong or persistent odors are not.

3. Check Thermostat - Replace batteries if applicable - Verify programming is correct - Test that system responds properly

4. Inspect Visible Components - Look at furnace exterior for damage or corrosion - Check for any loose panels or parts - Ensure area around furnace is clear (3-foot minimum)

5. Check Vents and Registers - Open all registers (or most—closing too many causes problems) - Remove obstructions - Clean vent covers if dusty

6. Inspect Flue and Venting - Check that flue pipe is secure and undamaged - Ensure exterior vent is clear of debris - Look for bird nests or blockages

Professional Fall Maintenance

Schedule a professional tune-up including:

• Heat exchanger inspection (critical for safety)
• Combustion analysis
• Gas pressure check
• Electrical connections inspection
• Blower motor check
• Safety controls testing

When to schedule: September or October for Bay Area Tip: Book early to ensure preferred scheduling

Safety Checks

Carbon Monoxide Detectors - Test all detectors - Replace batteries - Replace detectors older than 5-7 years - Ensure detectors on each level and near bedrooms

Smoke Detectors - Test and replace batteries - Heating season increases fire risk

Gas Connections - Smell for gas around furnace - If you smell gas, leave and call gas company

Efficiency Preparations

Seal Drafts - Check weatherstripping on doors and windows - Seal gaps around pipes and wires entering home - Use door sweeps if needed

Attic Insulation - Check insulation levels - Add insulation if below recommended levels

Programmable Thermostat - Set heating schedule - Use setback temperatures when away/sleeping - Consider smart thermostat upgrade

Bay Area Winter Notes

Our winters are mild but damp:

• Humidity control matters as much as heat
• Systems may run more frequently than you expect
• Hill areas get colder than bayside

Even in mild years, having a reliable heating system provides comfort and peace of mind.
