I don't think pulling wire is that likely, at least probably not with recent construction in a place with code enforcement. Standard here would be a 120v 20 amp circuit on 12 gauge romex... I'm not an electrical engineer, but shouldn't that be sufficient for nearly 2000 watts constant load?  I've done a little bit of homeowner construction to code, and they make you run a separate circuit for just about damn near everything these days, except lights...  I guess the concern would be if you've got an old 15 amp circuit on skinny little wire or hooked up to your air conditioner....
