Generator Installation in Dallas

Whole-Home Backup Power Sized for Your Electrical Load

A standby generator must do more than produce electricity. Its capacity, transfer equipment, fuel source, placement, and electrical connections must work together to keep your chosen systems running during an outage.

We begin planning with an electrical load calculation based on the home’s actual usage requirements. This calculation helps determine whether you need broader whole-home backup power or coverage for critical circuits serving essentials such as refrigeration, lighting, communications, security equipment, or medically important devices.

Call (972) 619-7607 to schedule a consultation about generator installation and your backup power priorities.

Home Electrical Service in Dallas Since 1910

We have served homeowners across the Dallas-Fort Worth area since 1910, including under the former Levy and Son identity. Backed by the national Service Experts network, our technicians are licensed, bonded, insured, and ACE-certified.

The Service Experts Guarantee states that equipment we work on or install will be set up with care and precision according to manufacturer standards. That standard is especially important when backup equipment, transfer controls, and existing wiring must operate as one coordinated system.

How We Plan & Install a Standby Generator

Every property has a different combination of electrical demand, available fuel, site constraints, and backup power priorities. We start by identifying what you want the equipment to power and calculating the electrical load required to meet that goal.

Installation planning typically addresses:

  • Power priorities: Identifying whether you want selected essential systems or broader household coverage.
  • Load calculation: Matching equipment capacity to the home’s electrical usage requirements.
  • Site planning: Considering placement, required clearances, fuel availability, and property restrictions.
  • Electrical integration: Coordinating the equipment with properly selected transfer controls and the existing electrical system.
  • System testing: Checking startup and transfer operation, then reviewing basic operation with the homeowner.

Natural gas and LP fuel may be options for whole-home systems, depending on the property and selected equipment. Permit review, fuel connections, site preparation, and inspection requirements vary by project, so these details must be evaluated for the individual property.

After installation, our technicians can also diagnose maintenance or repair needs when the system requires service.

FAQs We’ve Got Answers to Your Electrical Services Questions
  • Efficiency can be improved by using energy-efficient appliances and light bulbs, adding insulation to walls and attics, and sealing air leaks.

  • Signs of electrical service issues include flickering lights, frequent circuit breaker trips, hot or discolored electrical outlets or switches, buzzing sounds from outlets or switches, and burning smells. Another issue is improper outlets in the kitchen or bathroom – which should be GFCI (ground fault circuit interrupter) outlets. This is a shock-resistant outlet that acts as a safety measure and helps prevent fire hazards since water is a great conductor of electricity.

  • It is recommended that electrical service be inspected at least every 10 years to ensure that it is safe and up to code.

  • Some safety precautions include turning off the power supply before working on any electrical component, using insulated tools, wearing appropriate personal protective equipment (PPE), and following electrical codes and regulations.

  • A licensed electrician can perform an electrical load calculation to determine the right size of service needed for a home or business. This calculation takes into account the electrical needs of appliances, lighting, and other electrical devices.
