Generac Generator Maintenance
Living in the Lakes Region of Maine means you’re no stranger to unpredictable weather — from high winds and freezing rain in the winter to heavy summer storms that can knock out power in an instant. That’s why so many homeowners in Windham, Raymond, Naples, and surrounding towns rely on Generac standby generators to keep their homes running when the grid goes down.
But owning a generator is only half the battle. To make sure your system is ready to perform when it matters most, routine maintenance and occasional service are critical.
Why Regular Maintenance is Essential
A standby generator is a complex machine — and just like your vehicle, it needs regular attention to keep running reliably. Even if it hasn’t been used recently, parts inside your Generac system can still wear down over time. Fluids break down, batteries lose charge, and small issues can turn into major failures if left unchecked.
Generac recommends that standby generators be serviced at least once per year or after every 200 hours of run time — whichever comes first.
Regular maintenance helps:
Ensure the generator starts during an outage
Prevent costly emergency repairs
Extend the life of your system
Keep your manufacturer's warranty valid
What’s Included in a Standard Generator Maintenance Visit
At Peak Electric, we service Generac generators across the Lakes Region and follow a detailed inspection and tune-up process designed for Maine's seasonal climate shifts.
Each visit typically includes:
Oil and oil filter change
Air filter replacement
Spark plug inspection and replacement if needed
Full system inspection and diagnostic scan
Battery testing and cleaning of connections
Fuel system inspection for propane or natural gas units
Test run under load to ensure full functionality
Transfer switch inspection and test
We also check for any alerts or error codes on the system and make recommendations if anything needs attention.
Common Generator Repair Issues
Even well-maintained generators can run into problems over time — especially if they sit idle for long stretches or endure frequent power events. Some of the most common repairs we perform include:
Generator won’t start during an outage
Transfer switch failure
Low battery voltage or battery failure
Fuel delivery problems (especially with propane units)
Engine or starter motor failure
Fault codes such as RPM sense loss, overcrank, or low oil pressure
If your generator displays a red or yellow light, makes unusual noises during its weekly test, or hasn’t been serviced in over a year, it’s time to give us a call.
Signs Your Generator Needs Service
Homeowners in the Lakes Region rely on their generators most during storms, icy conditions, or high summer demand — times when getting emergency service can be tough. It's important to address warning signs before a failure occurs.
Be proactive if you notice:
Your generator hasn’t run its weekly test
Warning lights or alarm messages on the control panel
Excessive exhaust, vibration, or strange noises
The system fails to switch power over during an outage
It’s been more than 12 months since your last service
