A Lennox™ Residential Generator is installed permanently outside your home and is fueled by either natural gas or liquid propane (LP) gas. When an outage occurs, the generator starts up automatically—whether you're home or away—restoring power in as little as 10 seconds. Competitive models take up to 30 seconds to begin providing backup power.
Lennox™ Residential Generators are the strongest, fastest, cleanest and quietest generator systems available, as proven in our testing labs alongside competitors' units. As with our heating and cooling systems, Lennox dealers have the ability to offer a complete package, including installation, ongoing maintenance and service. Plus, our industry-leading warranty coverage gives you added peace of mind.
