How They Work

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. It restores power within as little as 10 seconds—no starter ropes, no extension cords, no hassles.
