Whole-house backup power for Texas homes. Generac & Kohler certified installers. Automatic transfer switches. Licensed electricians & gas fitters.
Texas weather is unpredictable. Ice storms, summer storms, grid failures—power outages can happen anytime. A whole-house standby generator keeps your lights on, AC running, food cold, and family safe when the grid goes down.
Unlike portable generators that require manual setup and refueling, a standby generator sits permanently outside your home, connects to your natural gas or propane line, and starts automatically within 10-30 seconds of detecting a power outage. You don't lift a finger—the lights stay on like nothing happened.

Protect your home, family, and peace of mind with backup power.
If the 2021 Texas winter storm left you without heat, water, or power for days, a generator ensures it never happens again. Many DFW homeowners installed generators after that wake-up call.
CPAP machines, oxygen concentrators, refrigerated medications, or mobility equipment that require power. A generator can be life-saving for medically dependent family members.
Power outages mean lost productivity, missed meetings, and potential income loss. A generator keeps your internet, computer, and workspace running during outages.
Some DFW neighborhoods experience more outages due to aging infrastructure or storm-prone locations. If you lose power 3+ times per year, a generator makes sense.
Homes with sump pumps risk flooding during outages. Well water systems mean no water when power is out. A generator keeps these critical systems running.
Knowing your family is safe, comfortable, and protected regardless of what happens to the grid. That peace of mind is worth it for many homeowners.

Call for Free AssessmentWhat to expect when you choose LEX for generator installation.
Our generator specialist visits your home to assess your electrical panel, available space for generator placement, and fuel source (natural gas or propane). We perform a load calculation to determine the right size generator for your needs.
We provide a detailed written quote including generator model, transfer switch, gas line work, permits, and installation. You review options (whole-house vs partial coverage, Generac vs Kohler) and approve the scope of work.

We deliver the generator, pour a concrete pad (if needed), set the generator, and install the automatic transfer switch at your electrical panel. Electrical connections are made per code.
Licensed gas fitters run natural gas or propane line from your meter/tank to the generator. All gas work is pressure-tested and leak-checked per code.

"After the winter storm knocked out power for days, we decided to get a generator. LEX handled everything—sizing, installation, permits, and inspections. When the next storm hit, we didn't lose power. Best investment we've made!"— Robert K., Preston Hollow

We install both brands. Here's how they compare.
Most Popular Choice
Best for: Most homeowners. Excellent value, proven track record, best warranty coverage.
Premium Choice
Best for: Homeowners who want the absolute best, prioritize quiet operation, or have larger homes (3,500+ sq ft).
Our recommendation: For most DFW homeowners, Generac offers the best value and warranty. Kohler is worth the premium if noise or longevity are priorities.
Best for most DFW homes with natural gas service
Pros:
Cons:
Our recommendation: If you have natural gas service, use it. The convenience and lower fuel cost make it the best choice for 90% of DFW homeowners.
Best for homes without natural gas service
Pros:
Cons:
Tank size: A 250-gallon propane tank runs a 22kW generator for 20-30 hours. 500-gallon tank runs 40-60 hours.
Keep your generator ready when you need it.
Maintenance schedule: Annual service is recommended. More frequent service (every 6 months) for generators that run weekly exercise cycles.
$299/year
Includes all items listed, plus priority service if you have a generator issue. Scheduled in spring or fall.
$499/year
Two visits per year (spring and fall). Best for generators that run weekly exercise cycles or homes where the generator is critical (medical equipment, etc.).
Most installations take 2-3 days. Day 1: Set generator and install transfer switch. Day 2: Gas line installation and electrical connections. Day 3: Startup, testing, and city inspection. The process from initial assessment to final inspection typically takes 3-4 weeks due to permitting.
If you have natural gas service, we recommend natural gas for convenience—no tank refills needed, lower fuel cost, and unlimited runtime. Propane is a good option for homes without natural gas service or for those who want guaranteed fuel availability even if gas lines fail.
Modern standby generators are much quieter than portable generators. Most run at 60-70 decibels—about as loud as normal conversation. Kohler generators are 3-5 dB quieter than Generac. The generator sits outside, so noise inside your home is minimal.
Yes, generator installations require electrical and gas permits from your city. We handle all permit applications and inspections in Dallas, Plano, Frisco, McKinney, Allen, Carrollton, and surrounding cities. Permit costs are included in our quotes.
We perform a load calculation based on your home's power requirements. Most homes need 18-22kW for whole-house coverage. Larger homes (3,500+ sq ft) or homes with multiple AC units may need 24-26kW. Partial coverage (essentials only) can work with 10-13kW.
On natural gas, a generator can run indefinitely as long as gas service is available. On propane, runtime depends on tank size and load. A 500-gallon propane tank runs a 22kW generator for 40-60 hours at 50% load. Most outages in DFW last less than 24 hours.
Yes. The automatic transfer switch detects power loss and signals the generator to start within 10-30 seconds. Your home transitions to generator power seamlessly. When utility power returns, the system automatically switches back and shuts down the generator.
Fuel cost depends on generator size and load. A 22kW generator at 50% load uses about $2-3/hour on natural gas or $4-6/hour on propane. Most outages last 4-12 hours, so total fuel cost is typically $20-50 per outage on natural gas.
Annual maintenance is recommended for most homeowners. Oil change, filter replacement, battery check, and test run. Generators that run weekly exercise cycles should be serviced every 6 months. We offer maintenance plans starting at $299/year.
Yes. A professionally installed standby generator typically increases home value by 3-5%, or $5,000-$15,000 depending on your home's value. It's also a strong selling point in Texas where power reliability is a concern for buyers.
Generac offers up to 10-year comprehensive warranty (varies by model). Kohler offers 5-year comprehensive warranty standard, with extended warranties available. Both warranties cover parts and labor when serviced by authorized dealers like LEX.
No. Generator installation requires licensed electrician (TECL license) and licensed gas fitter. DIY installation voids the warranty, violates code, and creates serious safety hazards (electrical shock, gas leaks, carbon monoxide). Insurance may not cover damage from unpermitted work.
