Generator Installation

Standby and portable generator installation. Keep your home powered when the Texas grid can't.

Texas power outages have taught Austin homeowners a hard lesson about grid reliability. Lonestar Electric Co installs whole-home standby generators and transfer switches that kick in automatically when power goes out. We also install manual transfer switches for portable generators, giving you a safe, code-compliant way to power essential circuits. From generator sizing and fuel connection to automatic transfer switch installation and city permits, we handle the complete project.

Frequently Asked Questions

What size generator do I need for my home?

A typical Austin home needs a 16-24 kW generator for whole-house coverage. If you only want to power essentials like HVAC, refrigerator, and lights, a smaller 10-14 kW unit works well. We perform a load calculation to size it right.

How does an automatic generator work?

An automatic transfer switch monitors your utility power 24/7. When it detects an outage, the generator starts within seconds and takes over your home's power supply. When utility power returns, it switches back and shuts down automatically.
