1) In the context where you are getting a technician, tradesperson or a repairman to come to your house, which phrase is more appropriate/common among native speakers? Is it a matter of difference in degrees of formality? Below are some example sentences I thought of.
I have a problem with my xxxx. Could you please come out and have a look.
xxxx has not been working for some time, so can you come over to check it out for me.
I think there is something wrong with my xxxx. I was wondering if you can send someone to have a look/ check it out.
2) What are some idiomatic and more concise alternatives to the two above? I have heard of the expression 'do a house call' and would like to know some others.
Many thanks in advance.
