Our take on the Generac Guardian 22kW Home Standby Generator 7043

The Generac Guardian 7043 is a 22 kW air-cooled home standby generator that runs on natural gas and starts automatically within seconds of an outage. It handles a 5-ton central air conditioner plus most of a typical home's essentials, and its 67 dB rating is quieter than many larger standby units. It is a whole-house-leaning model for homeowners who want permanent, hands-off backup rather than a portable unit. Compared with smaller Guardian models it carries more load, but it needs a natural gas line, a concrete pad and a licensed install.

Questions and answers

Is 22 kW enough for a whole house?
It runs a 5-ton central AC plus most essentials, but not every large load at once. Homes with electric heat, multiple AC units or EV charging may need a larger model.
Does it run on propane too?
This model is set up for natural gas. Propane requires a conversion kit and a tank, which changes output and fuel consumption.
How loud is it?
Generac rates it at 67 dB in normal operation, quieter than many larger standby units. Placement away from bedrooms and windows matters more than the number.
Does it start automatically?
Yes. It senses utility loss and starts on its own, then switches back when power returns. A compatible transfer switch is required.
What maintenance does it need?
Annual oil and filter changes, spark plug and air filter checks, and periodic exercise runs. Generac recommends a service plan for hands-off upkeep.
Does it include a CO sensor?
No. This model has low-oil shutdown and overload protection but no onboard CO sensor, so placement and clearances matter.
