What size generator do I need for my home?

The ideal wattage depends on whether you want to power your entire estate or just must-run essentials like well pumps and HVAC. For larger properties in Barrington, IL, North Barrington, and South Barrington, we typically recommend units between 20kW and 26kW to handle high-demand appliances. Barrington Electric performs detailed load calculations across the Chicago metro area to ensure your whole house generator installation provides enough headroom for your Inverness or Deer Park home to stay fully functional during a week-long outage.

Do you install automatic transfer switches?

Yes, an Automatic Transfer Switch ATS is the essential brain of any professional home standby generator installation. It monitors your utility power in Cook, Lake, and surrounding counties and automatically engages the generator within seconds of a failure. Whether you are in Barrington Hills, Tower Lakes, or Port Barrington, our trusted technicians ensure the ATS is seamlessly integrated into your main panel. We provide this critical generator service throughout Chicagoland to eliminate the need for manual switches or dangerous extension cords.

Do generators require permits in Barrington?

Absolutely. Local municipalities throughout the Barrington area require electrical and plumbing permits to ensure the unit meets strict safety, noise, and exhaust codes. Barrington Electric manages the entire permitting process for homeowners in Barrington Village Center, Tall Trees, and Barrington Meadows, coordinating with local inspectors to guarantee a legal and safe installation. By handling the paperwork for our clients in the Barrington area and surrounding suburbs, we ensure your whole-home generator project in Lake Barrington Shores or Barrington Oaks is completed without a hitch.

In today’s world, losing power is more than just a hassle — it can mean a home that gets too hot or too cold, food spoiling in the fridge, and security systems going dark. Unlike the portable generators you wheel out of the garage and manually start up in the middle of a storm, a standby generator is already connected directly to your home and its fuel supply. The moment it senses an outage, it turns itself on — often within seconds — and your family may barely notice anything happened at all.

At Barrington Electric, we help homeowners throughout Barrington, IL, find the right generator setup for their needs. We like to think of a whole-house generator as one of the best investments you can make — not unlike an insurance policy that actually pays off every time the lights go out on your street but stay on in your house. By focusing on dependable, high-powered solutions, we make sure families across the Chicagoland area stay comfortable, safe, and worry-free, no matter what the weather throws at us.
