3500/4000 Generator an AC

Any issues running a rooftop AC with this? Assuming my AC is 13500 BTU.
I will only do this in the event of a power outage where we are out for days.
  • Tom_M you are correct. I had problems with the ties snapping

    Basically, if it will run on 30 amp park current, it will run with the Champion.

    Here is a pic of mine that follows me everywhere. I only use when no power available.
    I noticed what appears to be hose storage is tie-wrapped to the bumper with white ties which are not UV resistant. These will deteriorate in a fairly short time from exposure to the sun. It would be better to use black UV resistant ties.
  • I have the Champ 3500 and $280 is a GREAT price for a great genny.

    I've run my 13.5 k A/C from my Champ 3500 in 103 degree heat at almost 4000 ft. In that heat and altitude it started and ran perfectly.

    I have inverter gennies that I use now for camping and I keep my beloved Champ for home backup. IMO you cannot beat the Champion 3500 for quality in a synchronous genny.
  • Thanks for the quick replies. I can get it where the Mrs. works for $280 after her employee discount.

  • My older Generac 4000xl runs a AC fine hear at sea level.

    What kind of Generator? I ask because "jobsite gennys" are often rated at 240-VAC. That's two 120-VAC legs at half the rated wattage. So a 3500-watt jobsite genny provides two 1750-watt circuits. A campsite genny, say 3000-watt Honda, lets you draw all 3000 from one circuit.

    So find out how the generator is set up. Harbor Fright, who I don't necessarily recommend for generators, only as an example, had two jobsite type gennys. One of them featured a 30A outlet. That setup would start and run a rooftop A/C.

    Most jobsite-style gennys are noisy.
