Homeowner Maintenance Guidance for Saint John Residents

In Saint John, keep exterior vent caps free of moss and debris, check attic and crawlspace duct insulation after storm season, and replace filters at the start of the long wet heating season.

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 Saint John home, especially outside sleeping areas.
