It is possible to spend too much time "making friends" and not enough time uncovering the need.
If you are talking about features and benefits you are missing the point of the interview. It seems you have failed to uncover the need.
Assuming you have qualified them before setting the appointment, try this after the warm up.
"I want to thank you again for inviting me in to your home. So I don't waste your time, tell me why you asked me to come here and discuss your needs and possible solutions to your concerns."
This forces them to come clean and gives you the key points you need to stress in your presentation. If they say something to the effect of "I just wanted to see what you had to offer" or "I am just checking prices", you don't have a qualified prospect and probably wasted a trip.
