Generators & Backup Power

Whole-Home Standby Generator Installation for Austin & the Texas Hill Country

Texas weather doesn't wait—and neither should you. From summer storms and ERCOT grid emergencies to the unexpected freeze, power outages in the Austin area have become more frequent and unpredictable. A whole-home standby generator ensures your family stays comfortable, your food stays fresh, and your home stays safe when the grid goes down.

At Malco Electric, we've been installing generators throughout Austin and the Texas Hill Country since 1983. Led by Master Electrician Randy Mallory (Lic. #6328), our team handles complete generator installations—from sizing and permitting to electrical hookup and final inspection.

Frequently Asked Questions

How much does a whole-home generator cost in Austin?

Whole-home generator costs in Austin typically range from $5,000 to $15,000+ installed, depending on the generator size (kW), fuel type, and installation complexity. A 22kW generator that powers most homes runs $8,000-$12,000 installed. We provide free in-home consultations with detailed, no-obligation quotes.

What size generator do I need for my house?

Generator sizing depends on what you want to power. A 10-14kW generator handles essential circuits. A 16-22kW generator powers most typical homes. Larger homes with pools, multiple HVAC systems, or well pumps may need 24kW or more. We perform a load calculation to determine your specific needs.

How long can a whole-home generator run continuously?

Natural gas generators can run indefinitely as long as gas supply is available. Propane generators run until the tank is empty—a 500-gallon tank typically provides 5-7 days of continuous power at 50% load. Standby generators are designed for extended operation.

Do I need a permit to install a generator in Texas?

Yes, generator installations require electrical and often gas permits in Texas. The work must pass inspection. Malco Electric handles all permit applications, inspections, and coordination as part of our installation service.

How quickly does a standby generator turn on during a power outage?

Automatic standby generators detect an outage and start within 10-30 seconds. The automatic transfer switch safely disconnects your home from the grid and connects to the generator—all without any action from you, even if you're away.
