Generac® Home Generator Installation & Generac® Generator Repairs
Don’t fear weather reports or spotty electrical services. Power your place with a Generac® whole home generator.
Every year, Kansas City-area homes and businesses experience power outages from severe weather, utility work, and grid malfunctions. These unexpected disruptions don’t just impact your comfort, spoil your food, and compromise your home security–post-outage power surges can put your whole electrical system at risk.
When candles don’t cut it, our Generac® generators keep your home or business humming, no matter what the weather or wires send your way. They automatically activate at the first sign of an outage and settle into standby mode when the power is back on–even when you’re away.
Don’t fear weather reports or spotty electrical services. Power your place with a Generac® whole home generator.
When you purchase a Generac® generator from Lancaster Brothers, we’ll include a
real-time remote monitoring system at no additional cost*. Our around-the-clock status monitor detects disruptions and error codes instantly alerting our team to any problems long before you notice an issue. (*Customer-provided Wifi required for free remote monitoring system use.)

Whole home flexibility
In addition to keeping your lights on, your Generac® generator can power your HVAC system, sump pump, kitchen appliances, security system, life-saving medical devices, and more. The right size generator for you depends on how many devices you want to power at once and the size of your home.
As part of our project quote process, we’ll talk about power capacity, load, and our flexible financing options–so you can find the best system and payment plan for your budget.
Never get left in the dark
