Generator Services in Charlotte, NC

A standby generator is permanently installed outside your home or business and turns on automatically when the power goes out. It is designed to power essential systems or even your entire property, depending on the size and setup. A portable generator is movable, typically runs on gasoline, and must be set up and started manually during an outage.

Standby generators are generally safer and more convenient because they connect through a transfer switch and provide automatic backup power without extension cords or manual fueling during severe weather.

The right generator size depends on what you want to power during an outage. Many homeowners choose to back up essentials like HVAC, refrigeration, lighting, sump pumps, medical devices, and internet. Others want whole home coverage for maximum comfort and convenience.

Roby Services can assess your electrical load, review your priorities, and recommend a generator that matches your home and lifestyle so you do not end up under powered or paying for capacity you do not need.

It can, as long as the generator is properly sized and the installation is designed to support those loads. HVAC systems are often the largest electrical demand in a home, so careful load planning is important. Many homeowners prioritize keeping climate control running during summer heat and winter cold for safety and comfort.

During your estimate, we can identify which HVAC equipment you want backed up and confirm what generator capacity and electrical upgrades may be required.

Run time depends on the fuel source and how much power your home is using. Many standby generators are connected to a natural gas line, which can provide extended run time during longer outages. Others use propane, which depends on tank size and usage.

We can explain expected run time based on your fuel type, generator size, and typical household loads so you can plan confidently for short and extended outages in the Charlotte area.

Yes. A transfer switch is a critical part of safe generator installation. It isolates your home from the utility grid during an outage, which helps prevent backfeeding and protects utility workers and your electrical system. Standby generators use an automatic transfer switch that shifts power seamlessly when the grid fails.

Roby Services installs generators with the proper transfer equipment so your backup power is safe, reliable, and code compliant.

If your generator does not start during an outage, it may be due to low battery voltage, a maintenance issue, a fuel supply problem, an error code that locked the unit out, or a transfer switch issue. Even small abnormalities during weekly self tests should be taken seriously because they can prevent operation when you need backup power most.

If your generator displays a warning or fails a test, schedule service so we can diagnose the cause and restore reliable performance.

Routine maintenance helps ensure your generator works when the grid fails. Most systems benefit from regular professional service based on run hours and manufacturer recommendations, along with periodic checks of the battery, oil, filters, and overall operation. Maintenance is especially important before storm season and periods of extreme temperatures.
