Refinancing?

I’m a little clueless about homeownership.

I bought my house just over a year ago. Since then my credit has gotten better and apparently interest rates are at a two year low. I have an offer that will save me 1.126% and roughly $200 a month.

How do I know if this is a good deal? Anything I need to look out for?
What’s a good closing cost?

Is there a professional I should be talking to about this?
