Neighbor is a HVAC technician and constantly bothering me

I am the least friendly person on my street and I am proud of that title. I don’t like to make or have friends. Friends are a ton of work, constantly need favors and provide no benefit to you. I also like that I can go grocery shopping, take a walk or mow my lawn without anyone talking to me. I try to be as unfriendly as possible. The only person who has not realized my unfriendly ways is my neighbor Bob. Bob owns his own HVAC company. He does HVAC installation, HVAC tune ups and also common HVAC repairs. Bob is constantly coming over to the house and handing me a flyer for his HVAC business. I don’t even know if he is NATE certified or even rated by the BBB. I feel like Bob is just a guy with a toolbox that happens to know a lot about HVAC. All I know is that Bob is super annoying and is desperate to look at my heating and cooling equipment. I don’t support this behavior and he will never get his hands on my HVAC. I take the flyers and use them for scrap paper. Anytime he talks to me about his HVAC services I don’t ever respond. I tried at one point playing deaf, Bob saw right through me. I need to work on my strategy and get where he feels he can’t knock on my door anymore. I have thought about saying I don’t own any HVAC for religious reasons. Then maybe he would leave me alone.
