In house vs home visits
Solution 1:
This is rather a quirky aspect of English and might seem rather strange to foreign speakers.
In-house acupuncture
This means that acupuncture is done on-site. This does not have anything to do with visiting other people's homes.
Home-visit/house-visit acupuncture
In-Home Acupuncture
Acupuncture done by House-calls
These mean you visit someone's house and do acupuncture. The latter two sound the least awkward of the three to me.
