Homeowner Maintenance Guidance for Cornish Flat Residents

In Cornish Flat, schedule an annual 21-point safety inspection before November cold snaps, verify that basement supply ducts are properly mastic-sealed, and never run a furnace with a yellow or flickering burner flame.

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 Cornish Flat home, especially outside sleeping areas.
