Running the self-test is an important part of your generator’s maintenance plan
Standby generators are the gold standard for emergency electrical power for your home or small business. When there’s an outage, the generator kicks in automatically and provides service for hours or days, energizing your fridge, phone and all your essentials. It will do the job whenever you need it—if you do your job to maintain it properly.
Once a standby generator is permanently installed in your yard, it will last a long time if well-maintained, potentially 20 years or more. The self-testing feature is a primary reason these generators are so reliable.
How self-testing works
Each week, the standby generator turns itself on for about 10 minutes, based on a programmed schedule. The day and time can be set from the control board, and for convenience, your installer can program your unit to run self-tests weekly, bi-weekly or monthly.
Any problem that’s detected is read by a remote indoor monitor that transmits data to your maintenance team, who will determine if your generator needs service.
Also important: the test charges the 12-volt car battery the generator uses so it’s ready to go the moment a blackout occurs.
Is it noisy?
Most generators are relatively quiet during the self-test, like a car idling in your driveway. Some of the best standby generators on the market, like the Generac Guardian series, have recently been enhanced to further lower the decibel level.
Be sure to listen for and monitor the results of these exercises. You can also read the display inside your generator to gather all the data points from the last test run. Another simple visual inspection: check the external indicator light, which should be green if it’s running properly. Red indicates an operating problem and requires a service visit by a certified technician to keep the warranty intact.
Remote access to data
If you’re away from home, don’t worry. The Generac Guardian series and other top-of-the-line generators have remote Wi-Fi monitoring capability. Weekly data results can be transmitted to a smartphone, tablet, or PC.
“Our customers can check the status of their generators even when they’re at work or on vacation,” notes Mike DeJoseph, owner of Bloomfield Cooling, Heating, & Electric, Inc. “If they get an alert that their generator is running when it shouldn’t, or if there’s an operational problem, they can contact us right away so we can check out the issue.”
Maintenance to-do list
- Monitor oil levels monthly, or more when the generator is running for longer periods of time; be sure the breaker and unit are off before pulling out the dipstick. Oil levels are key to maintaining the warranty.
- Keep the area around the unit clear and easily accessible, especially near the intake and exhaust areas. The generator needs air to work properly. Leaves, snow, or nesting birds and animals can all interfere with operation.
Scheduled inspections
A factory certified technician should fully inspect your generator annually or more depending on usage and more extreme weather. Make sure the installer or contractor has a comprehensive checklist for your specific unit which includes:
- Starters and alternators
- Transfer switch operation and controls (detects service interruption and disconnects your house from the utility)
- Air (intake and exhaust, filter replacement)
- Electrical connections and voltage input
- Fuel lines and hoses
- Oil and oil filter (change at least twice a year)
- Load testing (to verify overall reliability to run at full kW output)

At Bloomfield Cooling, Heating & Electric, Inc., we switched to a refrigerant called R-410A. In fact, we have been using it since 1995 when it was first introduced, because it is much more environmentally friendly. Unlike R-22, 401A does not contain bromine or chlorine (which contribute to ozone depletion). It also enables higher SEER (seasonal energy efficiency ratio) ratings, reducing power consumption which in turn reduces greenhouse gas emissions from power plants.
