IS YOUR HOME READY FOR THE NEXT OUTAGE?
Signs you May Need a Standby Generator...
You Work from Home
Remote workers and home-based professionals in Andover can't afford to lose internet or power. A generator keeps your connectivity and home office equipment running no matter what New England weather brings.
Medical Equipment in the Home
Oxygen concentrators, CPAP machines, refrigerated medications - if someone in your home relies on powered medical equipment, uninterrupted power isn't optional.
Refrigerators & Freezers at Risk
A 24-hour outage can mean hundreds of dollars in spoiled food. A standby generator kicks on automatically so your fridge and freezer never miss a beat, no manual action needed.
Frequent Power Outages
Andover's tree-lined neighborhoods and wooded lots are beautiful, but falling branches during New England storms are one of the most common causes of power outages. A standby generator eliminates the disruption permanently and kicks on automatically within seconds.
You Have a Sump Pump or Well
Many of Andover's larger single-family homes have basements and rely on sump pumps during heavy rain. A generator keeps your sump pump running automatically. No flooded basement, no expensive water damage.
Heating or Cooling Stops Working
Gas furnaces, heat pumps, and whole-home AC systems all require electricity. In a New England winter, losing heat in a large Andover home can be dangerous and costly. A generator ensures you're never without climate control.

Andover Standby Generator FAQ's
How do I know if my home needs a standby generator?
If your Andover home frequently loses power during storms, you rely on a sump pump, have medical equipment that requires constant power, or you work from home, a standby generator is a smart investment. Andover's wooded lots and tree-lined streets mean falling branches during New England storms regularly cause outages — a standby generator kicks on automatically within seconds so you never have to worry about it. Contact Sylvester Electric for a free in-home evaluation.
How long does a generator install take in Andover?
Most whole home generator installations in Andover are completed in one to two days. The timeline depends on the size of the generator, the complexity of your electrical system, and whether a gas line extension is needed. Our team will give you a clear timeline during your free estimate.
Is a permit required for a standby generator installation in Andover?
Yes, all standby generator installations in Andover, MA require a permit and an inspection. Sylvester Electric handles all permit filing and scheduling with the Town of Andover's building department as part of every installation. You don't have to manage any paperwork.
What size generator does my Andover home need?
Generator size depends on your home's square footage, the number of appliances you want to power, and your electrical panel capacity. Common sizes range from 11 kW for essential circuits to 22 kW for whole-home coverage. During our free estimate, we assess your specific power needs and recommend the right size Generac unit for your home and budget
What is the difference between a portable and a standby generator?
A portable generator must be manually started and connected — it runs on gasoline and requires refueling. A standby generator is permanently installed outside your home, connected to your natural gas or propane supply, and starts automatically within seconds of a power outage. Standby generators are safer, more convenient, and provide whole-home coverage without any manual action.
