Lennox^™ Home Generators

Lennox™ Residential Generators offer dependable protection during unexpected power outages. With a complete line of residential generators and transfer switches, Lennox provides the ideal solution—safe, reliable, automatic backup power for your home that lets you live your life without interruption. To learn about how backup generators work and to choose the right size for your home.

When the lights go out, so does your heating and cooling, creating a potentially dangerous and unhealthy situation in your home. To make matters worse, sump pumps stop working, which can lead to costly damage. You can also experience problems with your food spoiling, security system going down and family members getting hurt from falls.

Unlike a portable generator, which can be dangerous and difficult to operate, a Lennox Residential Generator senses a power outage and starts up automatically.Installed permanently outside your home, a Lennox generator runs on your liquid propane (LP) or natural gas supply and monitors incoming utility-line voltage. When power is interrupted, it immediately detects the problem and begins supplying electricity to your preselected circuits.

Why should I purchase a generator from Lennox instead of the competition?

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.

How does a Lennox generator protect my computer, TV or other electronic devices?

All Lennox generators are designed with the industry's strongest commercial–grade digital controller. The electronic governor ensures delivery of clean, low–distortion power to an amazing tolerance of +/- 0.5%, which exceeds even the standards set by most utility companies. Competitive products have tolerances of +/- 3.0Hz, a range nine times larger than ours.

What is the warranty coverage on a Lennox™ Residential Generator?

Every Lennox generator system is covered by a 5–year/2000–hour warranty that takes effect at the date and time your dealer starts up the unit for its initial test run. Specific details of the warranty program are outlined in the owner's manual. For added convenience and peace of mind, your Lennox dealer also offers long–term generator service and maintenance contracts.
