There are hundreds of posts on generators Just use the search menu at the top.
be prepared to do a lot of reading. There is more here than you would ever want to know. Most would say 3000 to 4000 watts either Honda or Yamaha.These are the two quietest

The new Yamaha is2400 is very capable of running your roof air, is very quiet, is the inverter type which does not run at full speed all the time and is only 65lbs. Plus you can buy it ready-converted to run on propane.....not gasoline..........a real bonus for longevity, safety and maintenance!!!

Welcome to the forums! If for some reason you and Angel73 don't strike a deal, you can always list your generator here in the forums classified ads.

The following is for non-inverter generators!

be careful of one thing. If a generator provides both 120V and 240V, it is probably wired with two windings in serial. This provides the total power output to the 240V plug, but only half power to each of the two 120V recepticles (each of the 120V recepticles is wired from the common connection between the windings and then to either end of the two windings, which means only the power from one winding is available to each recepticle).

So my 3500 Watt generator only delivers 1700 Watts at 120V (each recepticle), which is marginal for an AC that requires 13.5 Amps. I've looked at mine generator and it will be easy to rewire the windings in parallel, but I'd lose the 240V output, which I don't use.

By the way, YOU CAN'T PARALLEL THE OUTPUT OF THE TWO 120V RECEPTICLES without rewiring the windings--THEY ARE 180 DEGREES OUT OF PHASE!
