Whole Home Generator Service, Maintenance and Monitoring


Generator manufacturers recommend that generators be installed, serviced and repaired by an authorized dealer who is familiar with applicable codes, standards and regulations.


Despite the safe design of generators, neglecting maintenance or operating improperly can cause injury or death.

Installation, operation, servicing and repair of generators must always comply with applicable codes, standards, laws and regulations, including strictly adhering to local, state and national electrical and building codes


Generators produce dangerous electrical voltages that can cause fatal electric shock. Utility power delivers potentially lethal high voltage to the transfer switch as well.

The National Electric Code (NEC) requires the frame and external electrically conductive parts of generators to be connected to an approved earth ground and/or grounding rods.


Generators operate using one of several types of fuels. All fuel types are FLAMMABLE and should be handled with care.


Generators operate using one of several types of fuels. All fuel types are potentially EXPLOSIVE and should be handled with care.


Generator exhaust fumes contain carbon monoxide gas which can be DEADLY. If breathed in sufficient concentrations, carbon monoxide can cause unconsciousness or even death.


Often called the silent killer, carbon monoxide is an invisible, odorless, colorless gas created when fuels burn incompletely.

Carbon Monoxide (CO) alarms should be installed in a central location outside each sleeping area and on every level of the home and in other locations where required by applicable laws, codes or standards. For the best protection, interconnect all CO alarms throughout the home. When one sounds, they all sound.

Follow the manufacturer's instructions for placement and mounting height.

Choose a CO alarm that has a label of a recognized testing laboratory.

Call your local fire department's non-emergency number to find out what number to call if the CO alarm sounds.

Test CO alarms at least once a month. Replace them according to the manufacturer's instructions.

If the audible trouble signal sounds, check for low batteries. If the battery is low, replace it. If it still sounds, call the fire department.

If the CO alarm sounds, immediately move to a fresh air location outdoors. Make sure everyone inside the home is accounted for. Call for help from a fresh air location and stay there until emergency personnel arrive.

If you need to warm a vehicle, remove it from the garage immediately after starting it. Do not run a vehicle or other fueled engine or motor indoors, even if the garage doors are open. Make sure the exhaust pipe of a running vehicle is not covered with snow.
