Faeries are being of their own, and 'summoning' them isn't as accurate as 'trying to get their attention' which often times is a tad contrary to the goal, as many people aim to live coinciding with them, rather than calling them from their business to something that is probably menial in their eyes.
However, depending on where you live and the kind that may be around, you could leave some milk, bread, or fruit outside your door for them as sign of good will and they would know your pleasant intentions. Betraying them isn't wise, so be kind and true with intent and heart.
Spending time in nature around your home, or finding a place in your dwelling that you feel is connected to the Fae and showing respect and enjoyment of the company is a good way to keep good ties too.
You wouldn't 'see' the Fae if you did happen to summon it, and it would come in a different way than you probably expected, because they march to their own drum - which is why they all come differently.
If you contacted them in a cordial manner they would be pleasant I imagine, many tales in folklore of the Fae are consistent with that. Be rude and you'll probably find yourself with some bad luck.
