Our electricians work with permanently installed standby generators and coordinate the equipment with your electrical panel, transfer switch, and the systems you want to keep running during an outage.

Generator Installation
Woodstock provides professional generator installation in McHenry County for homeowners who watn backup power available automatically when an outage occurs. We help determine which electrical loads you want to protect, size the equipment appropriately, and install the generator and transfer equipment for safe integration with your home’s electrical system.
Generator Replacement
If an older standby generator is becoming unreliable or no longer provides enough capacity for your home, replacement may be the better long-term option. Woodstock can evaluate the existing generator and electrical setup, help you choose properly sized replacement generator equipment, and complete the electrical work for the new system.
Generator Repair
A standby generator needs to be ready before the power goes out. If your system won’t start, produces warning codes, fails its regular testing cycle, or is otherwise not operating properly, Woodstock provides generator repair in McHenry County to diagnose the problem and determine what is needed to restore dependable backup power.
We Install Generac Generators in McHenry County
Generac home standby generators are designed specifically for automatic whole-home backup and are available in a wide range of capacities, from smaller air-cooled units to larger liquid-cooled units for higher electrical demands. Woodstock installs Generac generators in McHenry County and works directly with Generac sizing guidelines to match the right model to your home’s electrical load, whether you’re backing up a few essential circuits or planning for near whole-home coverage. We evaluate key factors like HVAC tonnage, sump pumps, refrigeration, and overall panel capacity to ensure the selected Generac system can handle startup surges and sustained operation.
Types of Backup Generators
Backup power equipment comes in several different forms. The right option depends on how much power you need, how automatically you want the system to operate, and which appliances and systems you want to keep running.
Home Standby Generators
Home standby generators are permanently installed outside the home and connected to the electrical system through a transfer switch. They can automatically start when utility power fails and are the primary option for homeowners who want reliable, hands-off backup power for essential circuits or larger portions of the home.
Whole-House Standby Generators
Larger standby systems are designed to support most or all of a home’s normal electrical demand when properly sized. These systems can be a good fit for properties where homeowners want to maintain major appliances, HVAC equipment, lighting, and other important electrical loads during an extended outage.
Portable Generators
Portable generators provide temporary power through equipment that must be manually positioned, started, fueled, and connected appropriately during an outage. They can support selected appliances or circuits but don’t provide the automatic operation of a permanently installed standby system.
Inverter Generators
Inverter generators are typically smaller portable units designed to provide efficient, relatively stable power for a limited number of appliances or electronics. Their lower output generally makes them better suited to targeted backup needs than whole-home power.
Battery Backup Systems
Home battery systems store electricity for use when utility power is unavailable. Depending on their size and configuration, battery backup can support selected circuits or larger portions of the home and can sometimes be paired with solar generation or other backup-power equipment.
What Kind of Generator Do I Need for My Home?
Start by deciding what you expect to keep powered during an outage. A homeowner who only wants refrigeration, lights, and several essential circuits will have very different generator requirements from someone who wants to continue operating central air conditioning, heating equipment, well or sump pumps, and most of the home’s normal electrical loads. Woodstock can review the equipment you want backed up and recommend a generator with enough capacity to safely handle those loads.
