generators should be "exercised" every year just to "run them", unless stored inside a controlled environment. This is a rule of thumb ....
that being said ... it maybe a perfectly great unit .. but beware.
If you have no A/C perhaps a 1000 watt unit would be better for you ... much smaller .. easier to carry, and a bit quieter, ... and much cheeper secound hand ..as most people buy up when they realize they need more power ..
just a thought ..
