Answer

Hi there Fernando,

To speak respectfully in English, you change your phrasing to match a formal setting. 
English differs from Spanish in that there is no formal second-person pronoun (I believe it's "usted"?) However, instead of saying, "Hi, how are you?" you would say, "Hello, how are you doing?" 
Typically, formal/business English does not use shortened and contracted forms of words and phrases. Also, you would use titles where appropriate.

For example: (Casual) Formal
(Thanks!) Thank you.
(No problem!) You are welcome.
(I'm just going to the washroom. Be right back!) Excuse me, I need to use the facilities. 
(Hello, Sam!) Hello, Mr. Smith.

Hope this helps!
