Six HVAC professionals. Six cities. Six completely different ways of building a career and a business in one of the most in-demand trades in the country — from a solo starter in Phoenix chasing his first residential contract, to a 34-year owner in Portland working through succession, to a rural dual-fuel specialist in Vermont who learned the hard way what the paperwork actually protects.

Groundwork: HVAC follows their real decisions — licensing, first hires, commercial transitions, compliance headaches — through a structured roadmap covering all sixteen stages of building an HVAC business, backed by real cited regulation: EPA 608, OSHA, DOT, IRS, FTC, DOE SEER2 standards, mechanics liens, and more.

This isn't motivational talk about "following your trade." It's the terrain — permits, contracts, liability, and the mistakes that cost real money — mapped out by six people who actually walked it.
