Whole-Home Generator
Installation
Texas storms don't warn you. A standby generator kicks on automatically the moment the grid goes down — keeping your lights, AC, refrigerator, and medical equipment running without you lifting a finger.

Why It Matters
The Grid Goes Down. You Stay On.
DFW averages multiple major power outages per year from ice storms, hurricanes, and summer heat events. If you depend on electricity for medical equipment, have young children, or simply can't afford a hotel every time the grid fails — a standby generator is not a luxury. It's a necessity.
Unlike a portable generator (which requires manual setup and fuel runs), a standby generator is permanently installed, runs on your natural gas or propane line, and activates automatically within seconds of a power loss.
- Activates automatically — no action needed from you
- Runs indefinitely on natural gas — no fuel to store or haul
- Powers your entire home or just critical circuits
- Increases home resale value by 3–5%

Common Questions
Frequently Asked Questions
How much does a standby generator installation cost in DFW?
Total installed costs in DFW typically range from $5,000 to $15,000+ depending on generator size, transfer switch type, gas line distance, and permit requirements. We provide a fully itemized written quote before any work begins.
How long does installation take?
Most generator installations take 1–2 days. The electrical work and transfer switch are typically done in one day. Gas line coordination with your utility may add a day depending on their schedule.
Do I need to do anything when the power goes out?
Nothing. The automatic transfer switch detects the outage and starts the generator within 10–30 seconds. When utility power is restored, it switches back automatically and shuts the generator off.
What brands of generators do you install?
We install Generac, Kohler, Briggs & Stratton, and other major brands. We're not tied to one manufacturer — we recommend based on your needs, budget, and local service availability.
Does a generator require regular maintenance?
Yes. Most standby generators run a weekly self-test automatically. Annual professional maintenance (oil change, filter, spark plugs) is recommended to keep the warranty valid and ensure reliable operation.

They upgraded our electrical panel in one day. The electrician explained everything, kept the garage spotless, and even helped us understand which breakers controlled what. Incredible service.

I called at 10pm on a Saturday because half my house lost power. They had someone at my door within 45 minutes. Fixed a tripped main breaker and checked everything to make sure we were safe. Lifesaver.
