Bay Area winters are mild compared to much of the country, but chilly mornings and evenings still require reliable heating. Prepare your furnace before you need it.
DIY Preparation
Replace the air filter. Start heating season with a clean filter. Check monthly during operation.
Test the system. Run the furnace on a mild day. Verify it heats and that warm air comes from all vents.
Check carbon monoxide detectors. Test operation and replace batteries. These are critical safety devices for any home with gas appliances.
Clear around the furnace. Remove any items stored near the furnace. Maintain clearances specified by the manufacturer.
Check vents and returns. Ensure nothing blocks airflow. Open closed vents in occupied rooms.
Safety Inspection Points
Look for these warning signs: - Rust or corrosion on the furnace - Soot around the unit - Yellow or flickering burner flame - Unusual odors during operation - Cracks in the heat exchanger (requires professional inspection)
Any of these warrant professional inspection before operating the system.
Professional Maintenance
Annual furnace maintenance typically includes: - Heat exchanger inspection - Burner cleaning and adjustment - Blower motor inspection - Electrical connection check - Safety control testing - Thermostat calibration
Professional inspection catches potential problems and ensures safe operation.
Bay Area Heating Considerations
Mild climate advantages: Our winters are easy on heating systems compared to cold climates. Equipment often lasts longer with proper maintenance.
Extended off-seasons: Systems may sit idle for months. Pre-season testing ensures they work when needed.
Victorian and older homes: Many have original heating systems or retrofits. Professional inspection is especially important for older equipment.
If You Find Problems
Schedule repairs before cold weather arrives. Fall service calls typically have shorter waits than emergency calls during cold snaps.
Do not ignore warning signs hoping the system will make it through winter. Safety issues especially need prompt attention.
Heat Pump Homes
If you have a heat pump for heating: - Clean outdoor unit - Check refrigerant lines for damage - Verify heating mode operation - Inspect auxiliary heat elements (if applicable)
Heat pumps need maintenance for both heating and cooling seasons.
Backup Plans
Even with preparation, heating systems can fail: - Know how to find emergency service - Have portable heaters available (use safely) - Know friends or family who could provide temporary shelter
Bay Area winters are survivable without heat, but having backup options provides peace of mind.
