- Is the Generac 7043 enough to run my whole house?
- For most homes up to about 4,000 square feet with two central AC units, yes. Add up your largest loads, especially AC, well pump and electric heat, to confirm 22 kW covers them.
- Does it run on natural gas or propane?
- Both. It is rated 22 kW on propane and 19,500 W on natural gas, so output drops slightly on natural gas.
- How loud is it?
- Generac rates it at 57–67 dB(A), with the higher figure under load. That is about the level of a loud conversation to a lawn mower at close range.
- Does it have a CO shutdown sensor?
- No. This model lacks the CO sensor found on newer Generac units, so correct placement away from windows and doors matters.
- How long can it run during an outage?
- Indefinitely, as long as natural gas or propane keeps flowing. There is no onboard fuel tank, so runtime depends on your supply.
- What maintenance does it need?
- Annual oil and filter changes, spark plug checks and a battery inspection. Generac's 5-year limited warranty covers parts, not routine service.
