Homeowner Maintenance Guidance for National City Residents

Homeowners across National City are advised to replace disposable furnace filters every 60 to 90 days, ensure basement supply dampers are open, and test carbon monoxide alarms prior to winter heating activation.

Check Thermostat Setting:Confirm the system switch is set to "HEAT" and the fan is on "AUTO" to avoid room-temperature air circulating between cycles.
Inspect Filter Condition:Clogged return filters cause heat to build up inside the plenum, tripping the high-temperature limit switch and locking out burners.
Test Carbon Monoxide Alarms:Install and test digital CO detectors on every level of your National City home, especially outside sleeping areas.
