Why Greater Houston Homeowners Choose Whole Home Generators

Storm Season Protection

Houston’s hurricane season brings power outages lasting days or weeks. A whole home generator automatically powers essential systems—air conditioning, refrigerators, water heaters, medical equipment, lighting—without manual intervention. When the grid fails, your generator starts automatically and keeps your home running.

Professional Installation to Code

Generator installation involves electrical permits, proper fuel supply, exhaust venting, transfer switch integration, and comprehensive testing. Our certified electricians handle every aspect to local code, ensuring your system is safe, legal, and covered by warranty.

Automatic Transfer Switch Integration

Our installations include automatic transfer switches that detect power outages and seamlessly transfer your home’s load to the generator—all without you lifting a finger. When utility power returns, the switch transfers back automatically. This automation is what separates professional installations from DIY approaches.

Regular Maintenance and Testing

Generators sitting idle can fail when called upon during emergencies. Our maintenance program includes monthly exercise runs, fuel system checks, coolant and oil service, battery testing, and transfer switch verification. Regular testing ensures your generator starts reliably when a storm threatens.

Emergency Repair and Support

If your generator fails during a power outage, we respond quickly to diagnose and repair the problem. We also maintain fuel supply contracts so your generator keeps running as long as needed during extended outages.

Generator Services

Generator Services We Offer

From initial installation to emergency repair during outages, we provide comprehensive generator services to keep your backup power system reliable.

Generators - whole-home standby generator

Installing a whole home generator starts with understanding your home’s electrical load, fuel preferences (natural gas or propane), and backup power priorities. We install and service Generac and Champion standby generators—two of the most trusted names in home backup power—and we assess which systems you want to power during outages (HVAC, refrigeration, medical equipment, lighting) to size your generator to handle that load reliably.

We then design the installation: generator placement (usually on a concrete pad beside your home), natural gas or propane line connection, electrical service upgrades if needed, automatic transfer switch installation, exhaust venting, and fuel storage. We pull permits, complete all installation to code, perform comprehensive testing, and provide documentation and operating training. Your generator is ready to protect your home from day one. Learn more about generator installation.

When your generator fails—whether during a storm outage or during a maintenance test—diagnosis requires understanding fuel systems, electrical operation, and ignition controls. We test fuel supply, check the battery and starter, verify electrical output, inspect the engine for damage, and evaluate the transfer switch.

Common failures include dead or weak batteries (most common), fuel contamination or line blockage, spark plug failure, alternator problems, or engine overload conditions. We pinpoint the issue, explain what’s wrong, and provide repair options. Battery replacements are quick and affordable; fuel system cleaning restores operation after prolonged idle periods; engine repairs are more involved. Discover our generator repair process.

Regular maintenance ensures your generator starts reliably when a power outage occurs. Our maintenance program includes monthly exercise runs (operating the generator at load for 20–30 minutes to exercise the engine and verify operation), fuel system inspection and treatment (preventing fuel degradation during idle periods), oil and coolant changes, battery testing and cleaning, transfer switch verification, and engine inspection.

Monthly exercise runs are crucial—generators stored idle can develop fuel sludge, corroded contacts, or weak batteries. Monthly use prevents these problems and gives you confidence the system will start during an emergency. See what’s included in generator maintenance.

Generator FAQs

Generator Questions Greater Houston Homeowners Ask

For a natural gas generator, cost depends on your local gas rates and is generally modest for fuel alone. Propane costs vary with propane prices and tend to run somewhat higher. These are rough estimates; actual costs depend on generator size, electrical load, and fuel prices. Monthly exercise runs (20–30 minutes) cost just a few dollars.

Yes, if your system includes an automatic transfer switch (which our installations do). The switch detects power loss in seconds, starts the generator, and transfers your home’s load to generator power—all automatically. You don’t need to do anything.

A whole home generator can run indefinitely as long as fuel is available. For natural gas, supply is continuous. For propane, you need to monitor tank levels and arrange refills before fuel runs out. We help you plan fuel supply to cover extended outages.

This depends on which systems you want to power during an outage. A 10 kW generator powers essential loads (HVAC, refrigerator, water heater, lighting); a 20 kW unit powers most of your home simultaneously. We assess your electrical panel and recommend sizing during a consultation. Oversizing wastes money; undersizing leaves critical systems unpowered.

Yes, but AC requires significant power (3–5 kW). A typical 20 kW generator can run your AC plus other loads. If you only want essential backup (no AC), a 10 kW unit suffices. We design systems based on your priorities—cooling is a common priority in Houston heat.

We recommend monthly exercise runs (operating the generator under load for 20–30 minutes), plus annual professional service including oil changes, fuel treatment, battery testing, and transfer switch verification. Monthly exercise is the most important task—it keeps the engine in working order and ensures reliable startup during emergencies.

We provide emergency repair service during power outages. Call us immediately—we prioritize outage situations. However, prevention through regular maintenance is the best approach. Monthly exercise runs and annual service catch problems before they become emergencies.

Generator installation requires electrical permits, natural gas or propane line work, transfer switch integration, and safety testing. DIY installation violates building codes, voids manufacturer warranty, and creates electrical and fuel hazards. Always hire licensed electricians and HVAC professionals for generator work.

A properly sized and installed generator can power your entire home—or just essential circuits, depending on size and design. We discuss your priorities (full-home power vs. essential-only) during consultation and size the system accordingly. Full-home coverage requires larger, more expensive generators.

A typical whole home generator installation takes 2–4 days, depending on generator size, fuel supply complexity, and transfer switch integration. We coordinate all permit work, electrical connections, fuel supply, and testing. You’ll have detailed timeline and updates throughout the process.
