Trying to get HVAC sales from outside the US, how should I go about it?

I really enjoy sales jobs, and I believe greed drives humanity forward.

I sold plenty of home security systems, plumbing services and cooling units by phone in my country and made good money.

then I thought damn if I did something similar in the US I'd be making ×5 times my current numbers.

I don't have any issue learning the intricacies of a specific domain. my English is great and I have no accent.

however, I'm unsure about the approach, I thought about opening google maps and just calling every HVAC business in Michigan offering them leads and just cold call every establishment in their area, but I lack logistics, and I lack technical knowledge.
