Residential Backup Generator Services in Houston, TX

Home generator installation in Houston

OneCall Houston installs, repairs, and maintains home backup generators. We help you plan which circuits or appliances a standby system should support during an outage.

The right generator size depends on the equipment you want to keep running. Refrigerators, lights, key outlets, and heating or cooling systems can have different starting and operating loads. We review those needs along with electrical service and fuel supply.

What to discuss before installation

Tell us about essential equipment, available outdoor space, and any planned home upgrades. We explain generator options, transfer equipment, installation requirements, and the limits of the proposed setup.

An existing generator also needs inspection and maintenance. Share its make, age, and service history when you request generator service. For related electrical work, see our installation services.

Sizing and installation

We calculate the load for the equipment you want to support. Large motors can need extra power when they start, so choosing by the generator’s size alone is not enough.

Installation planning includes:

  • A suitable outdoor location and required clearances.
  • A stable base.
  • Fuel supply and connections.
  • Electrical wiring and a transfer switch.
  • Permit and inspection requirements.

The transfer switch separates generator power from utility power and controls the changeover. We review whether the system will serve the whole home or selected circuits.

Once installed, we test the setup and explain its operation. We also show you where to find status information and how to arrange routine service.

Repairs and maintenance

A generator needs care even when it is rarely used. We check the battery, starting system, fluids, connections, and other parts listed in the maker’s service schedule.

Tell us about warning lights, failed starts, unusual noise, or problems during an exercise cycle. We can trace the fault and discuss repair options.

Routine service may include oil and filter changes, testing under load, and checking the transfer switch. The exact work depends on the model, hours of use, and maintenance history.

Keep records of service and fault messages. Before storm season, ask us about the checks your system needs so you can address known issues ahead of an outage.
