Homeowner Maintenance Guidance for Johnston City Residents

Homeowners in Johnston City should replace furnace air filters monthly throughout the winter season, clear exterior PVC exhaust and intake pipes after heavy snowstorms, and install carbon monoxide alarms on every floor outside bedrooms.

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 Johnston City home, especially outside sleeping areas.
