Homeowner Maintenance Guidance for Merrillville Residents

In Merrillville, test your heating system on the first cool September evening, keep return-air grilles unobstructed by furniture, and have venting checked after any major storm crosses Lake County.

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 Merrillville home, especially outside sleeping areas.
