Homeowner Maintenance Guidance for Merrimack Residents

Homeowners in Merrimack should have their flue and venting inspected each fall, keep heating-oil tank levels monitored where oil is used, and seal obvious duct leaks in unheated basements before New Hampshire winter sets in.

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 Merrimack home, especially outside sleeping areas.
