Whole-Home Generator Installation and Repair in League City, TX

We install and service whole home generators from Briggs & Stratton and Generac. These systems are permanently installed and connected directly to your home’s electrical panel, using your existing natural gas or propane supply to deliver uninterrupted power during extended outages.
Before installation, our team evaluates your home’s electrical load to determine the right generator size for your needs. This ensures essential systems like air conditioning, heating, refrigeration, lighting, and medical equipment continue to operate when the grid goes down.
In addition to installation, we provide generator repair and ongoing maintenance to keep your system ready when you need it. Regular maintenance helps prevent startup failures, fuel issues, and wear that can go unnoticed until an outage occurs.
If you already own a portable or standby generator, we can help make sure it is connected safely. Bob’s installs interlock kits and transfer equipment so power is delivered where you need it while protecting your electrical system and preventing backfeeding hazards.
Whether you are preparing for hurricane season or dealing with frequent outages, backup power gives your household stability and control when utility service is unavailable. Bob’s is here to help you plan, install, and maintain a generator system that fits your home and usage needs.
Generator Sizing and Runtime FAQs
How do I know what size generator my home needs?
Generator size depends on the electrical load you want to support during an outage. This includes essentials like HVAC systems, refrigerators, lighting, medical equipment, and electronics. Before installation, we evaluate your home’s electrical panel and usage to determine the correct generator size so you are not underpowered or overspending on capacity you do not need.
How long can a whole home generator run during an outage?
Whole home generators can run continuously as long as fuel is available. Systems connected to natural gas can operate for extended outages without refueling. Propane systems will run based on tank size and usage, often for several days or longer. Runtime depends on generator size, electrical demand, and fuel supply.
Will my generator turn on automatically?
Yes. Standby and whole home generators are designed to automatically detect power loss and restore electricity within seconds. Once utility power is restored, the generator shuts off and resets automatically.
Does a generator require maintenance?
Yes. Regular maintenance is important to ensure your generator starts and runs properly during an outage. Maintenance typically includes oil changes, battery checks, system testing, and inspection of fuel and electrical connections.
