  • Our take on the Generac 7043

    The Generac 7043 is a 22 kW air-cooled home standby generator that runs on propane or natural gas and starts itself within seconds of an outage. Its 999cc G-Force engine and 240 V output can carry a large home, including two 5-ton air conditioners, and it runs indefinitely as long as fuel is supplied. It is the biggest air-cooled unit in Generac's Guardian line, so it competes with liquid-cooled models on capacity while staying simpler and cheaper to install. Owners like the automatic operation and the 5-year warranty; the main complaints are noise under load and the fuel volume a 22 kW unit draws on natural gas.

    What reviewers say

    Owners of the 7043 mostly report reliable automatic backup through multi-day outages and praise the capacity for whole-home coverage. Criticism centers on noise at full load and the amount of fuel a 22 kW air-cooled unit consumes.

    What people mention
    • NoiseCriticisedOwners say it is clearly audible at full load, especially near bedrooms or property lines.
    • ReliabilityPraisedReviewers report it starting and carrying the house through outages lasting days.
    • Fuel useMixedNatural gas supply is convenient, but consumption at high load is heavy.
    • CapacityPraisedThe 22 kW rating handles whole homes with two AC units and a well pump.
    • InstallationMixedSetup is manageable for a licensed installer but needs a pad, gas line and transfer switch.

    Questions and answers

    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.
    Where is the Generac 7043 cheapest?
    At Crenvu, for $4,199.40, 51% under what the other stores charge, as of our latest check.
    Where can I buy the Generac 7043?
    9 stores we checked sell it, including Crenvu, Haney Equipment Company Athens Alabama, alt-electric.com, ToolUp.com, DK Hardware.
