Why DFW Homeowners Trust Guardian for Backup Power
Local and Owner-Operated: We are a locally owned and operated business. This means you get direct accountability, personalized care, and a team that takes personal pride in protecting our neighbors. You won't be handed off from salesman to project manager; you have a single point of contact from start to finish.
Dedicated Specialists: When you work with us, you get dedicated electricians and plumbers licensed in the state of Texas, including factory-certified Generac and Kohler technicians. No generic 'installation techs' or jack-of-all-trades crews. Unlike some electricians, AC companies, or contractors who "also do generators", whole-home backup power is all we do, every single day
True Turnkey Approach: We take care of everything! We handle city permitting, assist with HOA approvals, all project management, and more.
Completely Local: We live and work right here in the heart of Metroplex, meaning we understand local building codes, gas line requirements, and neighborhood layouts.
Uncompromising Protection: We use third-party inspections to guarantee compliance, maximize safety, and avoid frustrating city delays.
Totally Transparent Pricing: We believe in being honest and open at every step. Our complete, standalone installations begin at $13,500 or $215/mo for an 18kw generator, with the average project ranging from 14,500 to $16,500 with a 24kw - 26kw generator.
Planning & Custom System Design
No two homes are built exactly alike, and their backup power needs are just as unique. We kick off every project with a detailed on-site assessment to map your home’s layout, audit your electrical panel, and evaluate your fuel source, whether that is natural gas or liquid propane. From there, we engineer a custom backup blueprint designed specifically to deliver safe, efficient, and uninterrupted power the exact second your local grid fails.
True Turnkey Installation
Planning, permits, electrical connections, gas hookup, final inspections, and homeowner education, we've got you covered from start to finish. Our team manages the entire process by securing mandatory city permits, arranging required inspections, and providing the exact layout documentation your HOA needs for swift approval. Once the paperwork is greenlit, our specialized crew executes the physical installation. We safely connect your standby generator to your home’s electrical panel and fuel infrastructure with precision, ensuring you have reliable and safe backup power.
Final Walk Through and Training
We want you to feel completely confident in your investment. Before we call the job complete, we will walk you through the setup, connect your generator to your home Wi-Fi, and help you configure the mobile monitoring app. We will also walk you through a complete system demonstration so you thoroughly understand how the generator runs, how it detects outages, and exactly how it functions to protect your home.
How a Whole-Home Generator Works
A whole-home generator automatically protects your home when utility power goes out. The generator detects the outage, starts itself, and transfers your home from utility power to generator power through an automatic transfer switch.
When utility power returns, the system automatically transfers your home back to normal power and shuts the generator down after a short cool-down cycle.
Guardian Home Generators designs each system around your home’s electrical load, fuel source, equipment, and backup power needs.
Fully Automatic
When utility power is lost, the generator system detects the outage and starts automatically. You do not need to connect cords, move equipment, or manually start the generator.
Power Through Any Storm
A standby generator is permanently connected to your home’s natural gas (or propane). That means there is no fuel to store and no dangerous refueling during an outage. Natural gas will allow your generator to power through virtually any outage, and a propane system can last 2 - 7 days.
True Whole-Home Backup Power
Your new generator system sits between utility power and your home’s electrical system. When the power goes out, your entire home is covered. You'll never be without air conditioning, heating, refrigeration, lighting, internet, or garage door opener again!
