Steve Nelson & Nelson Mechanical has defaulted on over $30,000 worth of equipment he purchased from me back in 2022. He continues to be unresponsive on emails, phone calls, text messages, and mail. This is not an isolated issue with Steve Nelson ... if you plan on doing work with Nelson Mechanical, I would suggest taking full payment before anything is shipped.
